Psychologists who favor the biological approach believe that inherited predispositions as well as physiological processes can be used to explain differences in our personalities (Burger, 2008).\r\n\r\n<\/div>\r\nIn the field of behavioral genetics, the Minnesota Study of Twins Reared Apart\u2014a well-known study of the genetic basis for personality\u2014conducted research with twins from 1979 to 1999. In studying 350 pairs of twins, including pairs of identical and fraternal twins reared together and apart, researchers found that identical twins, whether raised together or apart, have very similar personalities (Bouchard, 1994; Bouchard, Lykken, McGue, Segal, &amp; Tellegen, 1990; Segal, 2012). These findings suggest the heritability of some personality traits. <strong>Heritability<\/strong> refers to the proportion of difference among people that is attributed to genetics. Some of the traits that the study reported as having more than a 0.50 heritability ratio include leadership, obedience to authority, a sense of well-being, alienation, resistance to stress, and fearfulness. The implication is that some aspects of our personalities are largely controlled by genetics; however, it\u2019s important to point out that traits are not determined by a single gene, but by a combination of many genes, as well as by epigenetic factors that control whether the genes are expressed.\r\n<div class=\"textbox tryit\">\r\n<h3>Try It<\/h3>\r\nhttps:\/\/assessments.lumenlearning.com\/assessments\/4615\r\n\r\n<\/div>\r\n<section data-depth=\"1\">\r\n<h2>Temperament<\/h2>\r\nMost contemporary psychologists believe temperament has a biological basis due to its appearance very early in our lives (Rothbart, 2011). As you learned when you studied lifespan development, Thomas and Chess (1977) found that babies could be categorized into one of three temperaments: easy, difficult, or slow to warm up. However, environmental factors (family interactions, for example) and maturation can affect the ways in which children\u2019s personalities are expressed (Carter et al., 2008).\r\n\r\nResearch suggests that there are two dimensions of our temperament that are important parts of our adult personality\u2014<em>reactivity<\/em> and <em>self-regulation<\/em> (Rothbart, Ahadi, &amp; Evans, 2000). Reactivity refers to how we respond to new or challenging environmental stimuli; self-regulation refers to our ability to control that response (Rothbart &amp; Derryberry, 1981; Rothbart, Sheese, Rueda, &amp; Posner, 2011). For example, one person may immediately respond to new stimuli with a high level of anxiety, while another barely notices it.\r\n<div data-type=\"note\" data-label=\"Connect the Concepts\">\r\n<div data-type=\"title\">\r\n<div data-type=\"title\">\r\n<div class=\"textbox exercises\">\r\n<h3>Connect the Concepts: Body Type and Temperament<\/h3>\r\nIs there an association between your body type and your temperament? The constitutional perspective, which examines the relationship between the structure of the human body and behavior, seeks to answer this question (Genovese, 2008). The first comprehensive system of constitutional psychology was proposed by American psychologist William H. Sheldon (1940, 1942). He believed that your body type can be linked to your personality. Sheldon\u2019s life\u2019s work was spent observing human bodies and temperaments. Based on his observations and interviews of hundreds of people, he proposed three body\/personality types, which he called somatotypes.\r\n\r\nThe three somatotypes are ectomorphs, endomorphs, and mesomorphs (Figure 1). Ectomorphs are thin with a small bone structure and very little fat on their bodies. According to Sheldon, the ectomorph personality is anxious, self-conscious, artistic, thoughtful, quiet, and private. They enjoy intellectual stimulation and feel uncomfortable in social situations. Actors Adrien Brody and Nicole Kidman would be characterized as ectomorphs. Endomorphs are the opposite of ectomorphs. Endomorphs have narrow shoulders and wide hips, and carry extra fat on their round bodies. Sheldon described endomorphs as being relaxed, comfortable, good-humored, even-tempered, sociable, and tolerant. Endomorphs enjoy affection and detest disapproval. Queen Latifah and Jack Black would be considered endomorphs. The third somatotype is the mesomorph. This body type falls between the ectomorph and the endomorph. Mesomorphs have large bone structure, well-defined muscles, broad shoulders, narrow waists, and attractive, strong bodies. According to Sheldon, mesomorphs are adventurous, assertive, competitive, and fearless. They are curious and enjoy trying new things, but can also be obnoxious and aggressive. Channing Tatum and Scarlett Johannson would likely be mesomorphs.\r\n<figure>\r\n\r\n[caption id=\"\" align=\"aligncenter\" width=\"515\"]<img class=\"\" src=\"https:\/\/s3-us-west-2.amazonaws.com\/courses-images-archive-read-only\/wp-content\/uploads\/sites\/902\/2015\/02\/23225018\/CNX_Psych_11_06_Somatotype.jpg\" alt=\"The outlines of three human somatotypes are shown.

Sheldon proposed three somatotypes: endomorphs, mesomorphs, and ectomorphs. Do you think Sheldon\u2019s ideas about somatotypes are generally accurate about most people?[\/caption]<\/figure>\r\nSheldon (1949) also conducted further research into somatotypes and criminality. He measured the physical proportions of hundreds of juvenile delinquent boys in comparison to male college students, and found that problem youth were primarily mesomorphs. Why might this be? Perhaps it\u2019s because they are quick to anger and don\u2019t have the restraint demonstrated by ectomorphs. Maybe it\u2019s because a person with a mesomorphic body type reflects high levels of testosterone, which may lead to more aggressive behavior. Can you think of other explanations for Sheldon\u2019s findings?\r\n\r\nSheldon\u2019s method of somatotyping is not without criticism, as it has been considered largely subjective (Carter &amp; Heath, 1990; Cort\u00e9s &amp; Gatti, 1972; Parnell, 1958). More systematic and controlled research methods did not support his findings (Eysenck, 1970). Consequently, it\u2019s not uncommon to see his theory labeled as pseudoscience, much like Gall\u2019s theory of phrenology (Rafter, 2007; Rosenbaum, 1995). However, studies involving correlations between somatotype, temperament, and children\u2019s school performance (Sanford et al., 1943; Parnell); somatotype and performance of pilots during wartime (Damon, 1955); and somatotype and temperament (Peterson, Liivamagi, &amp; Koskel, 2006) did support his theory.\r\n\r\n<\/div>\r\n<div class=\"textbox tryit\">\r\n<h3>Try It<\/h3>\r\nhttps:\/\/assessments.lumenlearning.com\/assessments\/4610\r\n\r\nhttps:\/\/assessments.lumenlearning.com\/assessments\/4611\r\n\r\nhttps:\/\/assessments.lumenlearning.com\/assessments\/4612\r\n\r\nhttps:\/\/assessments.lumenlearning.com\/assessments\/4613\r\n\r\nhttps:\/\/assessments.lumenlearning.com\/assessments\/4614\r\n\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/section><section data-depth=\"1\"><section data-depth=\"1\">\r\n<div class=\"textbox learning-objectives\">\r\n<h3>Think It Over<\/h3>\r\n<section data-depth=\"1\">\r\n<div data-type=\"exercise\">\r\n<div data-type=\"problem\">\r\n<ul>\r\n \t<li>Research suggests that many of our personality characteristics have a genetic component.

Do you tend to be sociable or shy? Passive or aggressive? Optimistic or pessimistic? Moody or even-tempered? Early trait theorists tried to describe all human personality traits. For example, one trait theorist, Gordon Allport (Allport &amp; Odbert, 1936), found 4,500 words in the English language that could describe people. He organized these personality traits into three categories: cardinal traits, central traits, and secondary traits. A cardinal trait is one that dominates your entire personality, and hence your life\u2014such as Ebenezer Scrooge\u2019s greed and Mother Theresa\u2019s altruism. Cardinal traits are not very common: Few people have personalities dominated by a single trait. Instead, our personalities typically are composed of multiple traits. Central traits are those that make up our personalities (such as loyal, kind, agreeable, friendly, sneaky, wild, and grouchy). Secondary traits are those that are not quite as obvious or as consistent as central traits. They are present under specific circumstances and include preferences and attitudes. For example, one person gets angry when people try to tickle him; another can only sleep on the left side of the bed; and yet another always orders her salad dressing on the side. And you\u2014although not normally an anxious person\u2014feel nervous before making a speech in front of your English class.\r\n\r\n<\/div>\r\nIn an effort to make the list of traits more manageable, Raymond Cattell (1946, 1957) narrowed down the list to about 171 traits. However, saying that a trait is either present or absent does not accurately reflect a person\u2019s uniqueness, because all of our personalities are actually made up of the same traits; we differ only in the degree to which each trait is expressed. Cattell (1957) identified 16 factors or dimensions of personality: warmth, reasoning, emotional stability, dominance, liveliness, rule-consciousness, social boldness, sensitivity, vigilance, abstractedness, privateness, apprehension, openness to change, self-reliance, perfectionism, and tension (Table 1). He developed a personality assessment based on these 16 factors, called the 16PF. Instead of a trait being present or absent, each dimension is scored over a continuum, from high to low. For example, your level of warmth describes how warm, caring, and nice to others you are. If you score low on this index, you tend to be more distant and cold. A high score on this index signifies you are supportive and comforting.\r\n<table summary=\"A three column table compares low scores and high scores for personality factors measured by the 16PF Questionnaire.

Hans and Sybil Eysenck believed that our personality traits are influenced by our genetic inheritance. (credit: \"Sirswindon\"\/Wikimedia Commons)[\/caption]\r\n\r\nPsychologists Hans and Sybil Eysenck were personality theorists (Figure 2) who focused on <strong>temperament<\/strong>, the inborn, genetically based personality differences that you studied earlier in the module. They believed personality is largely governed by biology. The Eysencks (Eysenck, 1990, 1992; Eysenck &amp; Eysenck, 1963) viewed people as having two specific personality dimensions: extroversion\/introversion and neuroticism\/stability.\r\n<figure><\/figure>\r\nAccording to their theory, people high on the trait of extroversion are sociable and outgoing, and readily connect with others, whereas people high on the trait of introversion have a higher need to be alone, engage in solitary behaviors, and limit their interactions with others. In the neuroticism\/stability dimension, people high on neuroticism tend to be anxious; they tend to have an overactive sympathetic nervous system and, even with low stress, their bodies and emotional state tend to go into a flight-or-fight reaction. In contrast, people high on stability tend to need more stimulation to activate their flight-or-fight reaction and are considered more emotionally stable. Based on these two dimensions, the Eysencks\u2019 theory divides people into four quadrants. These quadrants are sometimes compared with the four temperaments described by the Greeks: melancholic, choleric, phlegmatic, and sanguine (Figure 3).\r\n<figure>\r\n\r\n[caption id=\"\" align=\"aligncenter\" width=\"631\"]<img class=\"\" src=\"https:\/\/s3-us-west-2.amazonaws.com\/courses-images-archive-read-only\/wp-content\/uploads\/sites\/902\/2015\/02\/23225022\/CNX_Psych_11_04_Quadrants.jpg\" alt=\"A circle is divided vertically and horizontally into four sections by lines with arrows at the ends.

The Eysencks described two factors to account for variations in our personalities: extroversion\/introversion and emotional stability\/instability.[\/caption]<\/figure>\r\nLater, the Eysencks added a third dimension: psychoticism versus superego control (Eysenck, Eysenck &amp; Barrett, 1985). In this dimension, people who are high on psychoticism tend to be independent thinkers, cold, nonconformists, impulsive, antisocial, and hostile, whereas people who are high on superego control tend to have high impulse control\u2014they are more altruistic, empathetic, cooperative, and conventional (Eysenck, Eysenck &amp; Barrett, 1985).\r\n<div class=\"textbox tryit\">\r\n<h3>Try It<\/h3>\r\nhttps:\/\/assessments.lumenlearning.com\/assessments\/4616\r\n\r\n<\/div>\r\n<h2>The Big 5<\/h2>\r\nWhile Cattell\u2019s 16 factors may be too broad, the Eysenck\u2019s two-factor system has been criticized for being too narrow. Another personality theory, called the <strong>Five Factor Model<\/strong>, effectively hits a middle ground, with its five factors referred to as the Big Five personality traits. It is the most popular theory in personality psychology today and the most accurate approximation of the basic trait dimensions (Funder, 2001). The five traits are openness to experience, conscientiousness, extroversion, agreeableness, and neuroticism (Figure 4). A helpful way to remember the traits is by using the mnemonic OCEAN.\r\n\r\nIn the Five Factor Model, each person has each trait, but they occur along a spectrum. Openness to experience is characterized by imagination, feelings, actions, and ideas. People who score high on this trait tend to be curious and have a wide range of interests. Conscientiousness is characterized by competence, self-discipline, thoughtfulness, and achievement-striving (goal-directed behavior). People who score high on this trait are hardworking and dependable. Numerous studies have found a positive correlation between conscientiousness and academic success (Akomolafe, 2013; Chamorro-Premuzic &amp; Furnham, 2008; Conrad &amp; Patry, 2012; Noftle &amp; Robins, 2007; Wagerman &amp; Funder, 2007). Extroversion is characterized by sociability, assertiveness, excitement-seeking, and emotional expression. People who score high on this trait are usually described as outgoing and warm. Not surprisingly, people who score high on both extroversion and openness are more likely to participate in adventure and risky sports due to their curious and excitement-seeking nature (Tok, 2011). The fourth trait is agreeableness, which is the tendency to be pleasant, cooperative, trustworthy, and good-natured. People who score low on agreeableness tend to be described as rude and uncooperative, yet one recent study reported that men who scored low on this trait actually earned more money than men who were considered more agreeable (Judge, Livingston, &amp; Hurst, 2012). The last of the Big Five traits is neuroticism, which is the tendency to experience negative emotions. People high on neuroticism tend to experience emotional instability and are characterized as angry, impulsive, and hostile. Watson and Clark (1984) found that people reporting high levels of neuroticism also tend to report feeling anxious and unhappy. In contrast, people who score low in neuroticism tend to be calm and even-tempered.\r\n<figure>\r\n\r\n[caption id=\"\" align=\"aligncenter\" width=\"697\"]<img class=\"\" src=\"https:\/\/s3-us-west-2.amazonaws.com\/courses-images-archive-read-only\/wp-content\/uploads\/sites\/902\/2015\/02\/23225023\/CNX_Psych_11_07_BigFive.jpg\" alt=\"A diagram includes five vertically stacked arrows, which point to the left and right.

In the Five Factor Model, each person has five traits, each scored on a continuum from high to low. In the center column, notice that the first letter of each trait spells the mnemonic OCEAN.[\/caption]<\/figure>\r\nThe Big Five personality factors each represent a range between two extremes. In reality, most of us tend to lie somewhere midway along the continuum of each factor, rather than at polar ends. It\u2019s important to note that the Big Five traits are relatively stable over our lifespan, with some tendency for the traits to increase or decrease slightly. Researchers have found that conscientiousness increases through young adulthood into middle age, as we become better able to manage our personal relationships and careers (Donnellan &amp; Lucas, 2008). Agreeableness also increases with age, peaking between 50 to 70 years (Terracciano, McCrae, Brant, &amp; Costa, 2005). Neuroticism and extroversion tend to decline slightly with age (Donnellan &amp; Lucas; Terracciano et al.). Additionally, The Big Five traits have been shown to exist across ethnicities, cultures, and ages, and may have substantial biological and genetic components (Jang, Livesley, &amp; Vernon, 1996; Jang et al., 2006; McCrae &amp; Costa, 1997; Schmitt et al., 2007).\r\n<div data-type=\"note\" data-label=\"Link to Learning\">\r\n<div class=\"textbox examples\">\r\n<h3>Link to Learning<\/h3>\r\nTo find out about your personality and where you fall on the Big Five traits, follow this <a href=\"http:\/\/www.outofservice.com\/bigfive\/\" target=\"_blank\" rel=\"noopener noreferrer\">link<\/a> to take the Big Five personality test.\r\n\r\n<\/div>\r\n<div class=\"textbox tryit\">\r\n<h3>Try It<\/h3>\r\nhttps:\/\/assessments.lumenlearning.com\/assessments\/4617\r\n\r\nhttps:\/\/assessments.lumenlearning.com\/assessments\/4618\r\n\r\n<\/div>\r\n<div class=\"textbox learning-objectives\">\r\n<h3>Think It Over<\/h3>\r\n<section data-depth=\"1\">\r\n<div data-type=\"exercise\">\r\n<div data-type=\"problem\">\r\n<ul>\r\n \t<li>Review the Big Five personality traits shown in Figure 4.

The culture in which you live is one of the most important environmental factors that shapes your personality (Triandis &amp; Suh, 2002). The term <strong>culture<\/strong> refers to all of the beliefs, customs, art, and traditions of a particular society. Culture is transmitted to people through language as well as through the modeling of culturally acceptable and nonacceptable behaviors that are either rewarded or punished (Triandis &amp; Suh, 2002). With these ideas in mind, personality psychologists have become interested in the role of culture in understanding personality. They ask whether personality traits are the same across cultures or if there are variations. It appears that there are both universal and culture-specific aspects that account for variation in people\u2019s personalities.\r\n\r\n<\/div>\r\nWhy might it be important to consider cultural influences on personality? Western ideas about personality may not be applicable to other cultures (Benet-Martinez &amp; Oishi, 2008). In fact, there is evidence that the strength of personality traits varies across cultures. Let\u2019s take a look at some of the Big Five factors (conscientiousness, neuroticism, openness, and extroversion) across cultures. As you will learn when you study social psychology, Asian cultures are more collectivist, and people in these cultures tend to be less extroverted. People in Central and South American cultures tend to score higher on openness to experience, whereas Europeans score higher on neuroticism (Benet-Martinez &amp; Karakitapoglu-Aygun, 2003).\r\n\r\nAccording to this study, there also seem to be regional personality differences within the United States (Figure 5). Researchers analyzed responses from over 1.5 million individuals in the United States and found that there are three distinct regional personality clusters: Cluster 1, which is in the Upper Midwest and Deep South, is dominated by people who fall into the \u201cfriendly and conventional\u201d personality; Cluster 2, which includes the West, is dominated by people who are more relaxed, emotionally stable, calm, and creative; and Cluster 3, which includes the Northeast, has more people who are stressed, irritable, and depressed. People who live in Clusters 2 and 3 are also generally more open (Rentfrow et al., 2013).\r\n<figure>\r\n\r\n[caption id=\"\" align=\"aligncenter\" width=\"658\"]<img class=\"\" src=\"https:\/\/s3-us-west-2.amazonaws.com\/courses-images-archive-read-only\/wp-content\/uploads\/sites\/902\/2015\/02\/23225025\/CNX_Psych_11_08_Clusters.jpg\" alt=\"A map of the United States is shown.

Cluster 2 occurs mainly on the west side of the country. Cluster 3 occurs mainly in the North-East region of the country and also in Texas. These are generalizations; there are several states which are comprised of a combination of two different clusters.\" width=\"658\" height=\"512\" data-media-type=\"image\/jpeg\" \/> Figure 5. Researchers found three distinct regional personality clusters in the United States. People tend to be friendly and conventional in the Upper Midwest and Deep South; relaxed, emotionally stable, and creative in the West; and stressed, irritable, and depressed in the Northeast (Rentfrow et al., 2013).[\/caption]<\/figure>\r\nOne explanation for the regional differences is <strong>selective migration<\/strong> (Rentfrow et al., 2013). Selective migration is the concept that people choose to move to places that are compatible with their personalities and needs. For example, a person high on the agreeable scale would likely want to live near family and friends, and would choose to settle or remain in such an area. In contrast, someone high on openness would prefer to settle in a place that is recognized as diverse and innovative (such as California).\r\n\r\n<section data-depth=\"1\">\r\n<h2>Personality in Individualist and Collectivist Cultures<\/h2>\r\nIndividualist cultures and collectivist cultures place emphasis on different basic values. People who live in individualist cultures tend to believe that independence, competition, and personal achievement are important. Individuals in Western nations such as the United States, England, and Australia score high on individualism (Oyserman, Coon, &amp; Kemmelmier, 2002). People who live in collectivist cultures value social harmony, respectfulness, and group needs over individual needs. Individuals who live in countries in Asia, Africa, and South America score high on collectivism (Hofstede, 2001; Triandis, 1995). These values influence personality. For example, Yang (2006) found that people in individualist cultures displayed more personally oriented personality traits, whereas people in collectivist cultures displayed more socially oriented personality traits.\r\n\r\n<\/section><section data-depth=\"1\">\r\n<h2>Approaches to Studying Personality in a Cultural Context<\/h2>\r\nThere are three approaches that can be used to study personality in a cultural context, the <em data-effect=\"italics\">cultural-comparative approach<\/em>; the <em data-effect=\"italics\">indigenous approach<\/em>; and the <em data-effect=\"italics\">combined approach<\/em>, which incorporates elements of both views. Since ideas about personality have a Western basis, the cultural-comparative approach seeks to test Western ideas about personality in other cultures to determine whether they can be generalized and if they have cultural validity (Cheung van de Vijver, &amp; Leong, 2011). For example, recall from the previous section on the trait perspective that researchers used the cultural-comparative approach to test the universality of McCrae and Costa\u2019s Five Factor Model. They found applicability in numerous cultures around the world, with the Big Five traits being stable in many cultures (McCrae &amp; Costa, 1997; McCrae et al., 2005). The indigenous approach came about in reaction to the dominance of Western approaches to the study of personality in non-Western settings (Cheung et al., 2011). Because Western-based personality assessments cannot fully capture the personality constructs of other cultures, the indigenous model has led to the development of personality assessment instruments that are based on constructs relevant to the culture being studied (Cheung et al., 2011). The third approach to cross-cultural studies of personality is the combined approach, which serves as a bridge between Western and indigenous psychology as a way of understanding both universal and cultural variations in personality (Cheung et al., 2011).\r\n<div class=\"textbox tryit\">\r\n<h3>Try It<\/h3>\r\nhttps:\/\/assessments.lumenlearning.com\/assessments\/4619\r\n\r\nhttps:\/\/assessments.lumenlearning.com\/assessments\/4620\r\n\r\nhttps:\/\/assessments.lumenlearning.com\/assessments\/4621\r\n\r\n<\/div>\r\n<\/section><section data-depth=\"1\">\r\n<div>\r\n<div class=\"textbox learning-objectives\">\r\n<h3>Think It Over<\/h3>\r\n<section data-depth=\"1\">\r\n<div data-type=\"exercise\">\r\n<div data-type=\"problem\">\r\n<ul>\r\n \t<li>According to the work of Rentfrow and colleagues, personalities are not randomly distributed.

Psychologists who favor the biological approach believe that inherited predispositions as well as physiological processes can be used to explain differences in our personalities (Burger, 2008).<\/p>\n<\/div>\n<p>In the field of behavioral genetics, the Minnesota Study of Twins Reared Apart\u2014a well-known study of the genetic basis for personality\u2014conducted research with twins from 1979 to 1999. In studying 350 pairs of twins, including pairs of identical and fraternal twins reared together and apart, researchers found that identical twins, whether raised together or apart, have very similar personalities (Bouchard, 1994; Bouchard, Lykken, McGue, Segal, &amp; Tellegen, 1990; Segal, 2012). These findings suggest the heritability of some personality traits. <strong>Heritability<\/strong> refers to the proportion of difference among people that is attributed to genetics. Some of the traits that the study reported as having more than a 0.50 heritability ratio include leadership, obedience to authority, a sense of well-being, alienation, resistance to stress, and fearfulness. The implication is that some aspects of our personalities are largely controlled by genetics; however, it\u2019s important to point out that traits are not determined by a single gene, but by a combination of many genes, as well as by epigenetic factors that control whether the genes are expressed.<\/p>\n<div class=\"textbox tryit\">\n<h3>Try It<\/h3>\n<p>\t<iframe id=\"lumen_assessment_4615\" class=\"resizable\" src=\"https:\/\/assessments.lumenlearning.com\/assessments\/load?assessment_id=4615&#38;embed=1&#38;external_user_id=&#38;external_context_id=&#38;iframe_resize_id=lumen_assessment_4615\" frameborder=\"0\" style=\"border:none;width:100%;height:100%;min-height:400px;\"><br \/>\n\t<\/iframe><\/p>\n<\/div>\n<section data-depth=\"1\">\n<h2>Temperament<\/h2>\n<p>Most contemporary psychologists believe temperament has a biological basis due to its appearance very early in our lives (Rothbart, 2011). As you learned when you studied lifespan development, Thomas and Chess (1977) found that babies could be categorized into one of three temperaments: easy, difficult, or slow to warm up. However, environmental factors (family interactions, for example) and maturation can affect the ways in which children\u2019s personalities are expressed (Carter et al., 2008).<\/p>\n<p>Research suggests that there are two dimensions of our temperament that are important parts of our adult personality\u2014<em>reactivity<\/em> and <em>self-regulation<\/em> (Rothbart, Ahadi, &amp; Evans, 2000). Reactivity refers to how we respond to new or challenging environmental stimuli; self-regulation refers to our ability to control that response (Rothbart &amp; Derryberry, 1981; Rothbart, Sheese, Rueda, &amp; Posner, 2011). For example, one person may immediately respond to new stimuli with a high level of anxiety, while another barely notices it.<\/p>\n<div data-type=\"note\" data-label=\"Connect the Concepts\">\n<div data-type=\"title\">\n<div data-type=\"title\">\n<div class=\"textbox exercises\">\n<h3>Connect the Concepts: Body Type and Temperament<\/h3>\n<p>Is there an association between your body type and your temperament? The constitutional perspective, which examines the relationship between the structure of the human body and behavior, seeks to answer this question (Genovese, 2008). The first comprehensive system of constitutional psychology was proposed by American psychologist William H. Sheldon (1940, 1942). He believed that your body type can be linked to your personality. Sheldon\u2019s life\u2019s work was spent observing human bodies and temperaments. Based on his observations and interviews of hundreds of people, he proposed three body\/personality types, which he called somatotypes.<\/p>\n<p>The three somatotypes are ectomorphs, endomorphs, and mesomorphs (Figure 1). Ectomorphs are thin with a small bone structure and very little fat on their bodies. According to Sheldon, the ectomorph personality is anxious, self-conscious, artistic, thoughtful, quiet, and private. They enjoy intellectual stimulation and feel uncomfortable in social situations. Actors Adrien Brody and Nicole Kidman would be characterized as ectomorphs. Endomorphs are the opposite of ectomorphs. Endomorphs have narrow shoulders and wide hips, and carry extra fat on their round bodies. Sheldon described endomorphs as being relaxed, comfortable, good-humored, even-tempered, sociable, and tolerant. Endomorphs enjoy affection and detest disapproval. Queen Latifah and Jack Black would be considered endomorphs. The third somatotype is the mesomorph. This body type falls between the ectomorph and the endomorph. Mesomorphs have large bone structure, well-defined muscles, broad shoulders, narrow waists, and attractive, strong bodies. According to Sheldon, mesomorphs are adventurous, assertive, competitive, and fearless. They are curious and enjoy trying new things, but can also be obnoxious and aggressive. Channing Tatum and Scarlett Johannson would likely be mesomorphs.<\/p>\n<figure>\n<div style=\"width: 525px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"\" src=\"https:\/\/s3-us-west-2.amazonaws.com\/courses-images-archive-read-only\/wp-content\/uploads\/sites\/902\/2015\/02\/23225018\/CNX_Psych_11_06_Somatotype.jpg\" alt=\"The outlines of three human somatotypes are shown.

Sheldon proposed three somatotypes: endomorphs, mesomorphs, and ectomorphs. Do you think Sheldon\u2019s ideas about somatotypes are generally accurate about most people?<\/p>\n<\/div>\n<\/figure>\n<p>Sheldon (1949) also conducted further research into somatotypes and criminality. He measured the physical proportions of hundreds of juvenile delinquent boys in comparison to male college students, and found that problem youth were primarily mesomorphs. Why might this be? Perhaps it\u2019s because they are quick to anger and don\u2019t have the restraint demonstrated by ectomorphs. Maybe it\u2019s because a person with a mesomorphic body type reflects high levels of testosterone, which may lead to more aggressive behavior. Can you think of other explanations for Sheldon\u2019s findings?<\/p>\n<p>Sheldon\u2019s method of somatotyping is not without criticism, as it has been considered largely subjective (Carter &amp; Heath, 1990; Cort\u00e9s &amp; Gatti, 1972; Parnell, 1958). More systematic and controlled research methods did not support his findings (Eysenck, 1970). Consequently, it\u2019s not uncommon to see his theory labeled as pseudoscience, much like Gall\u2019s theory of phrenology (Rafter, 2007; Rosenbaum, 1995). However, studies involving correlations between somatotype, temperament, and children\u2019s school performance (Sanford et al., 1943; Parnell); somatotype and performance of pilots during wartime (Damon, 1955); and somatotype and temperament (Peterson, Liivamagi, &amp; Koskel, 2006) did support his theory.<\/p>\n<\/div>\n<div class=\"textbox tryit\">\n<h3>Try It<\/h3>\n<p>\t<iframe id=\"lumen_assessment_4610\" class=\"resizable\" src=\"https:\/\/assessments.lumenlearning.com\/assessments\/load?assessment_id=4610&#38;embed=1&#38;external_user_id=&#38;external_context_id=&#38;iframe_resize_id=lumen_assessment_4610\" frameborder=\"0\" style=\"border:none;width:100%;height:100%;min-height:400px;\"><br \/>\n\t<\/iframe><\/p>\n<p>\t<iframe id=\"lumen_assessment_4611\" class=\"resizable\" src=\"https:\/\/assessments.lumenlearning.com\/assessments\/load?assessment_id=4611&#38;embed=1&#38;external_user_id=&#38;external_context_id=&#38;iframe_resize_id=lumen_assessment_4611\" frameborder=\"0\" style=\"border:none;width:100%;height:100%;min-height:400px;\"><br \/>\n\t<\/iframe><\/p>\n<p>\t<iframe id=\"lumen_assessment_4612\" class=\"resizable\" src=\"https:\/\/assessments.lumenlearning.com\/assessments\/load?assessment_id=4612&#38;embed=1&#38;external_user_id=&#38;external_context_id=&#38;iframe_resize_id=lumen_assessment_4612\" frameborder=\"0\" style=\"border:none;width:100%;height:100%;min-height:400px;\"><br \/>\n\t<\/iframe><\/p>\n<p>\t<iframe id=\"lumen_assessment_4613\" class=\"resizable\" src=\"https:\/\/assessments.lumenlearning.com\/assessments\/load?assessment_id=4613&#38;embed=1&#38;external_user_id=&#38;external_context_id=&#38;iframe_resize_id=lumen_assessment_4613\" frameborder=\"0\" style=\"border:none;width:100%;height:100%;min-height:400px;\"><br \/>\n\t<\/iframe><\/p>\n<p>\t<iframe id=\"lumen_assessment_4614\" class=\"resizable\" src=\"https:\/\/assessments.lumenlearning.com\/assessments\/load?assessment_id=4614&#38;embed=1&#38;external_user_id=&#38;external_context_id=&#38;iframe_resize_id=lumen_assessment_4614\" frameborder=\"0\" style=\"border:none;width:100%;height:100%;min-height:400px;\"><br \/>\n\t<\/iframe><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/section>\n<section data-depth=\"1\">\n<section data-depth=\"1\">\n<div class=\"textbox learning-objectives\">\n<h3>Think It Over<\/h3>\n<section data-depth=\"1\">\n<div data-type=\"exercise\">\n<div data-type=\"problem\">\n<ul>\n<li>Research suggests that many of our personality characteristics have a genetic component.

Do you tend to be sociable or shy? Passive or aggressive? Optimistic or pessimistic? Moody or even-tempered? Early trait theorists tried to describe all human personality traits. For example, one trait theorist, Gordon Allport (Allport &amp; Odbert, 1936), found 4,500 words in the English language that could describe people. He organized these personality traits into three categories: cardinal traits, central traits, and secondary traits. A cardinal trait is one that dominates your entire personality, and hence your life\u2014such as Ebenezer Scrooge\u2019s greed and Mother Theresa\u2019s altruism. Cardinal traits are not very common: Few people have personalities dominated by a single trait. Instead, our personalities typically are composed of multiple traits. Central traits are those that make up our personalities (such as loyal, kind, agreeable, friendly, sneaky, wild, and grouchy). Secondary traits are those that are not quite as obvious or as consistent as central traits. They are present under specific circumstances and include preferences and attitudes. For example, one person gets angry when people try to tickle him; another can only sleep on the left side of the bed; and yet another always orders her salad dressing on the side. And you\u2014although not normally an anxious person\u2014feel nervous before making a speech in front of your English class.<\/p>\n<\/div>\n<p>In an effort to make the list of traits more manageable, Raymond Cattell (1946, 1957) narrowed down the list to about 171 traits. However, saying that a trait is either present or absent does not accurately reflect a person\u2019s uniqueness, because all of our personalities are actually made up of the same traits; we differ only in the degree to which each trait is expressed. Cattell (1957) identified 16 factors or dimensions of personality: warmth, reasoning, emotional stability, dominance, liveliness, rule-consciousness, social boldness, sensitivity, vigilance, abstractedness, privateness, apprehension, openness to change, self-reliance, perfectionism, and tension (Table 1). He developed a personality assessment based on these 16 factors, called the 16PF. Instead of a trait being present or absent, each dimension is scored over a continuum, from high to low. For example, your level of warmth describes how warm, caring, and nice to others you are. If you score low on this index, you tend to be more distant and cold. A high score on this index signifies you are supportive and comforting.<\/p>\n<table summary=\"A three column table compares low scores and high scores for personality factors measured by the 16PF Questionnaire.

The Eysencks (Eysenck, 1990, 1992; Eysenck &amp; Eysenck, 1963) viewed people as having two specific personality dimensions: extroversion\/introversion and neuroticism\/stability.<\/p>\n<figure><\/figure>\n<p>According to their theory, people high on the trait of extroversion are sociable and outgoing, and readily connect with others, whereas people high on the trait of introversion have a higher need to be alone, engage in solitary behaviors, and limit their interactions with others. In the neuroticism\/stability dimension, people high on neuroticism tend to be anxious; they tend to have an overactive sympathetic nervous system and, even with low stress, their bodies and emotional state tend to go into a flight-or-fight reaction. In contrast, people high on stability tend to need more stimulation to activate their flight-or-fight reaction and are considered more emotionally stable. Based on these two dimensions, the Eysencks\u2019 theory divides people into four quadrants. These quadrants are sometimes compared with the four temperaments described by the Greeks: melancholic, choleric, phlegmatic, and sanguine (Figure 3).<\/p>\n<figure>\n<div style=\"width: 641px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"\" src=\"https:\/\/s3-us-west-2.amazonaws.com\/courses-images-archive-read-only\/wp-content\/uploads\/sites\/902\/2015\/02\/23225022\/CNX_Psych_11_04_Quadrants.jpg\" alt=\"A circle is divided vertically and horizontally into four sections by lines with arrows at the ends.

The Eysencks described two factors to account for variations in our personalities: extroversion\/introversion and emotional stability\/instability.<\/p>\n<\/div>\n<\/figure>\n<p>Later, the Eysencks added a third dimension: psychoticism versus superego control (Eysenck, Eysenck &amp; Barrett, 1985). In this dimension, people who are high on psychoticism tend to be independent thinkers, cold, nonconformists, impulsive, antisocial, and hostile, whereas people who are high on superego control tend to have high impulse control\u2014they are more altruistic, empathetic, cooperative, and conventional (Eysenck, Eysenck &amp; Barrett, 1985).<\/p>\n<div class=\"textbox tryit\">\n<h3>Try It<\/h3>\n<p>\t<iframe id=\"lumen_assessment_4616\" class=\"resizable\" src=\"https:\/\/assessments.lumenlearning.com\/assessments\/load?assessment_id=4616&#38;embed=1&#38;external_user_id=&#38;external_context_id=&#38;iframe_resize_id=lumen_assessment_4616\" frameborder=\"0\" style=\"border:none;width:100%;height:100%;min-height:400px;\"><br \/>\n\t<\/iframe><\/p>\n<\/div>\n<h2>The Big 5<\/h2>\n<p>While Cattell\u2019s 16 factors may be too broad, the Eysenck\u2019s two-factor system has been criticized for being too narrow. Another personality theory, called the <strong>Five Factor Model<\/strong>, effectively hits a middle ground, with its five factors referred to as the Big Five personality traits. It is the most popular theory in personality psychology today and the most accurate approximation of the basic trait dimensions (Funder, 2001). The five traits are openness to experience, conscientiousness, extroversion, agreeableness, and neuroticism (Figure 4). A helpful way to remember the traits is by using the mnemonic OCEAN.<\/p>\n<p>In the Five Factor Model, each person has each trait, but they occur along a spectrum. Openness to experience is characterized by imagination, feelings, actions, and ideas. People who score high on this trait tend to be curious and have a wide range of interests. Conscientiousness is characterized by competence, self-discipline, thoughtfulness, and achievement-striving (goal-directed behavior). People who score high on this trait are hardworking and dependable. Numerous studies have found a positive correlation between conscientiousness and academic success (Akomolafe, 2013; Chamorro-Premuzic &amp; Furnham, 2008; Conrad &amp; Patry, 2012; Noftle &amp; Robins, 2007; Wagerman &amp; Funder, 2007). Extroversion is characterized by sociability, assertiveness, excitement-seeking, and emotional expression. People who score high on this trait are usually described as outgoing and warm. Not surprisingly, people who score high on both extroversion and openness are more likely to participate in adventure and risky sports due to their curious and excitement-seeking nature (Tok, 2011). The fourth trait is agreeableness, which is the tendency to be pleasant, cooperative, trustworthy, and good-natured. People who score low on agreeableness tend to be described as rude and uncooperative, yet one recent study reported that men who scored low on this trait actually earned more money than men who were considered more agreeable (Judge, Livingston, &amp; Hurst, 2012). The last of the Big Five traits is neuroticism, which is the tendency to experience negative emotions. People high on neuroticism tend to experience emotional instability and are characterized as angry, impulsive, and hostile. Watson and Clark (1984) found that people reporting high levels of neuroticism also tend to report feeling anxious and unhappy. In contrast, people who score low in neuroticism tend to be calm and even-tempered.<\/p>\n<figure>\n<div style=\"width: 707px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"\" src=\"https:\/\/s3-us-west-2.amazonaws.com\/courses-images-archive-read-only\/wp-content\/uploads\/sites\/902\/2015\/02\/23225023\/CNX_Psych_11_07_BigFive.jpg\" alt=\"A diagram includes five vertically stacked arrows, which point to the left and right.

In the Five Factor Model, each person has five traits, each scored on a continuum from high to low. In the center column, notice that the first letter of each trait spells the mnemonic OCEAN.<\/p>\n<\/div>\n<\/figure>\n<p>The Big Five personality factors each represent a range between two extremes. In reality, most of us tend to lie somewhere midway along the continuum of each factor, rather than at polar ends. It\u2019s important to note that the Big Five traits are relatively stable over our lifespan, with some tendency for the traits to increase or decrease slightly. Researchers have found that conscientiousness increases through young adulthood into middle age, as we become better able to manage our personal relationships and careers (Donnellan &amp; Lucas, 2008). Agreeableness also increases with age, peaking between 50 to 70 years (Terracciano, McCrae, Brant, &amp; Costa, 2005). Neuroticism and extroversion tend to decline slightly with age (Donnellan &amp; Lucas; Terracciano et al.). Additionally, The Big Five traits have been shown to exist across ethnicities, cultures, and ages, and may have substantial biological and genetic components (Jang, Livesley, &amp; Vernon, 1996; Jang et al., 2006; McCrae &amp; Costa, 1997; Schmitt et al., 2007).<\/p>\n<div data-type=\"note\" data-label=\"Link to Learning\">\n<div class=\"textbox examples\">\n<h3>Link to Learning<\/h3>\n<p>To find out about your personality and where you fall on the Big Five traits, follow this <a href=\"http:\/\/www.outofservice.com\/bigfive\/\" target=\"_blank\" rel=\"noopener noreferrer\">link<\/a> to take the Big Five personality test.<\/p>\n<\/div>\n<div class=\"textbox tryit\">\n<h3>Try It<\/h3>\n<p>\t<iframe id=\"lumen_assessment_4617\" class=\"resizable\" src=\"https:\/\/assessments.lumenlearning.com\/assessments\/load?assessment_id=4617&#38;embed=1&#38;external_user_id=&#38;external_context_id=&#38;iframe_resize_id=lumen_assessment_4617\" frameborder=\"0\" style=\"border:none;width:100%;height:100%;min-height:400px;\"><br \/>\n\t<\/iframe><\/p>\n<p>\t<iframe id=\"lumen_assessment_4618\" class=\"resizable\" src=\"https:\/\/assessments.lumenlearning.com\/assessments\/load?assessment_id=4618&#38;embed=1&#38;external_user_id=&#38;external_context_id=&#38;iframe_resize_id=lumen_assessment_4618\" frameborder=\"0\" style=\"border:none;width:100%;height:100%;min-height:400px;\"><br \/>\n\t<\/iframe><\/p>\n<\/div>\n<div class=\"textbox learning-objectives\">\n<h3>Think It Over<\/h3>\n<section data-depth=\"1\">\n<div data-type=\"exercise\">\n<div data-type=\"problem\">\n<ul>\n<li>Review the Big Five personality traits shown in Figure 4.

The culture in which you live is one of the most important environmental factors that shapes your personality (Triandis &amp; Suh, 2002). The term <strong>culture<\/strong> refers to all of the beliefs, customs, art, and traditions of a particular society. Culture is transmitted to people through language as well as through the modeling of culturally acceptable and nonacceptable behaviors that are either rewarded or punished (Triandis &amp; Suh, 2002). With these ideas in mind, personality psychologists have become interested in the role of culture in understanding personality. They ask whether personality traits are the same across cultures or if there are variations. It appears that there are both universal and culture-specific aspects that account for variation in people\u2019s personalities.<\/p>\n<\/div>\n<p>Why might it be important to consider cultural influences on personality? Western ideas about personality may not be applicable to other cultures (Benet-Martinez &amp; Oishi, 2008). In fact, there is evidence that the strength of personality traits varies across cultures. Let\u2019s take a look at some of the Big Five factors (conscientiousness, neuroticism, openness, and extroversion) across cultures. As you will learn when you study social psychology, Asian cultures are more collectivist, and people in these cultures tend to be less extroverted. People in Central and South American cultures tend to score higher on openness to experience, whereas Europeans score higher on neuroticism (Benet-Martinez &amp; Karakitapoglu-Aygun, 2003).<\/p>\n<p>According to this study, there also seem to be regional personality differences within the United States (Figure 5). Researchers analyzed responses from over 1.5 million individuals in the United States and found that there are three distinct regional personality clusters: Cluster 1, which is in the Upper Midwest and Deep South, is dominated by people who fall into the \u201cfriendly and conventional\u201d personality; Cluster 2, which includes the West, is dominated by people who are more relaxed, emotionally stable, calm, and creative; and Cluster 3, which includes the Northeast, has more people who are stressed, irritable, and depressed. People who live in Clusters 2 and 3 are also generally more open (Rentfrow et al., 2013).<\/p>\n<figure>\n<div style=\"width: 668px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"\" src=\"https:\/\/s3-us-west-2.amazonaws.com\/courses-images-archive-read-only\/wp-content\/uploads\/sites\/902\/2015\/02\/23225025\/CNX_Psych_11_08_Clusters.jpg\" alt=\"A map of the United States is shown.

Cluster 2 occurs mainly on the west side of the country. Cluster 3 occurs mainly in the North-East region of the country and also in Texas. These are generalizations; there are several states which are comprised of a combination of two different clusters.\" width=\"658\" height=\"512\" data-media-type=\"image\/jpeg\" \/><\/p>\n<p class=\"wp-caption-text\">Figure 5. Researchers found three distinct regional personality clusters in the United States. People tend to be friendly and conventional in the Upper Midwest and Deep South; relaxed, emotionally stable, and creative in the West; and stressed, irritable, and depressed in the Northeast (Rentfrow et al., 2013).<\/p>\n<\/div>\n<\/figure>\n<p>One explanation for the regional differences is <strong>selective migration<\/strong> (Rentfrow et al., 2013). Selective migration is the concept that people choose to move to places that are compatible with their personalities and needs. For example, a person high on the agreeable scale would likely want to live near family and friends, and would choose to settle or remain in such an area. In contrast, someone high on openness would prefer to settle in a place that is recognized as diverse and innovative (such as California).<\/p>\n<section data-depth=\"1\">\n<h2>Personality in Individualist and Collectivist Cultures<\/h2>\n<p>Individualist cultures and collectivist cultures place emphasis on different basic values. People who live in individualist cultures tend to believe that independence, competition, and personal achievement are important. Individuals in Western nations such as the United States, England, and Australia score high on individualism (Oyserman, Coon, &amp; Kemmelmier, 2002). People who live in collectivist cultures value social harmony, respectfulness, and group needs over individual needs. Individuals who live in countries in Asia, Africa, and South America score high on collectivism (Hofstede, 2001; Triandis, 1995). These values influence personality. For example, Yang (2006) found that people in individualist cultures displayed more personally oriented personality traits, whereas people in collectivist cultures displayed more socially oriented personality traits.<\/p>\n<\/section>\n<section data-depth=\"1\">\n<h2>Approaches to Studying Personality in a Cultural Context<\/h2>\n<p>There are three approaches that can be used to study personality in a cultural context, the <em data-effect=\"italics\">cultural-comparative approach<\/em>; the <em data-effect=\"italics\">indigenous approach<\/em>; and the <em data-effect=\"italics\">combined approach<\/em>, which incorporates elements of both views. Since ideas about personality have a Western basis, the cultural-comparative approach seeks to test Western ideas about personality in other cultures to determine whether they can be generalized and if they have cultural validity (Cheung van de Vijver, &amp; Leong, 2011). For example, recall from the previous section on the trait perspective that researchers used the cultural-comparative approach to test the universality of McCrae and Costa\u2019s Five Factor Model. They found applicability in numerous cultures around the world, with the Big Five traits being stable in many cultures (McCrae &amp; Costa, 1997; McCrae et al., 2005). The indigenous approach came about in reaction to the dominance of Western approaches to the study of personality in non-Western settings (Cheung et al., 2011). Because Western-based personality assessments cannot fully capture the personality constructs of other cultures, the indigenous model has led to the development of personality assessment instruments that are based on constructs relevant to the culture being studied (Cheung et al., 2011). The third approach to cross-cultural studies of personality is the combined approach, which serves as a bridge between Western and indigenous psychology as a way of understanding both universal and cultural variations in personality (Cheung et al., 2011).<\/p>\n<div class=\"textbox tryit\">\n<h3>Try It<\/h3>\n<p>\t<iframe id=\"lumen_assessment_4619\" class=\"resizable\" src=\"https:\/\/assessments.lumenlearning.com\/assessments\/load?assessment_id=4619&#38;embed=1&#38;external_user_id=&#38;external_context_id=&#38;iframe_resize_id=lumen_assessment_4619\" frameborder=\"0\" style=\"border:none;width:100%;height:100%;min-height:400px;\"><br \/>\n\t<\/iframe><\/p>\n<p>\t<iframe id=\"lumen_assessment_4620\" class=\"resizable\" src=\"https:\/\/assessments.lumenlearning.com\/assessments\/load?assessment_id=4620&#38;embed=1&#38;external_user_id=&#38;external_context_id=&#38;iframe_resize_id=lumen_assessment_4620\" frameborder=\"0\" style=\"border:none;width:100%;height:100%;min-height:400px;\"><br \/>\n\t<\/iframe><\/p>\n<p>\t<iframe id=\"lumen_assessment_4621\" class=\"resizable\" src=\"https:\/\/assessments.lumenlearning.com\/assessments\/load?assessment_id=4621&#38;embed=1&#38;external_user_id=&#38;external_context_id=&#38;iframe_resize_id=lumen_assessment_4621\" frameborder=\"0\" style=\"border:none;width:100%;height:100%;min-height:400px;\"><br \/>\n\t<\/iframe><\/p>\n<\/div>\n<\/section>\n<section data-depth=\"1\">\n<div>\n<div class=\"textbox learning-objectives\">\n<h3>Think It Over<\/h3>\n<section data-depth=\"1\">\n<div data-type=\"exercise\">\n<div data-type=\"problem\">\n<ul>\n<li>According to the work of Rentfrow and colleagues, personalities are not randomly distributed.
