Consider two brothers. One of these siblings will grow up to become a world leader. The other will struggle with alcohol and drugs, eventually spending time in jail. What about each of their personalities propelled them to take the path they did?

Three months before William Jefferson Blythe III was born, his father died in a car accident. He was raised by his mother, Virginia Dell, and grandparents, in Hope, Arkansas. When he turned 4, his mother married Roger Clinton, Jr., an alcoholic who was physically abusive to William’s mother. Six years later, Virginia gave birth to another son, Roger. William, who later took the last name Clinton from his stepfather, became the 42nd president of the United States. While Bill Clinton was making his political ascendance, his half-brother, Roger Clinton, was arrested numerous times for drug charges, including possession, conspiracy to distribute cocaine, and driving under the influence, serving time in jail. Two brothers, raised by the same people, took radically different paths in their lives. Why did they make the choices they did? What internal forces shaped their decisions? Personality psychology can help us answer these questions and more.

  • Define personality
  • Describe early theories about personality development

Personality refers to the long-standing traits and patterns that propel individuals to consistently think, feel, and behave in specific ways. Our personality is what makes us unique individuals. Each person has an idiosyncratic pattern of enduring, long-term characteristics and a manner in which he or she interacts with other individuals and the world around them. Our personalities are thought to be long term, stable, and not easily changed. The word personality comes from the Latin word persona. In the ancient world, a persona was a mask worn by an actor. While we tend to think of a mask as being worn to conceal one’s identity, the theatrical mask was originally used to either represent or project a specific personality trait of a character (Figure).

Three masks are arranged side by side. The masks are almost identical, but with slightly different facial expressions resulting from the masks being at different angles. The first mask is tilted downward and has downcast eyes. The second mask is shown straight on and is directing its gaze slightly higher than the first. The third mask is tilted upwards so its gaze is directed more upward.
Happy, sad, impatient, shy, fearful, curious, helpful. What characteristics describe your personality?

HISTORICAL PERSPECTIVES

The concept of personality has been studied for at least 2,000 years, beginning with Hippocrates in 370 BCE (Fazeli, 2012). Hippocrates theorized that personality traits and human behaviors are based on four separate temperaments associated with four fluids (“humors”) of the body: choleric temperament (yellow bile from the liver), melancholic temperament (black bile from the kidneys), sanguine temperament (red blood from the heart), and phlegmatic temperament (white phlegm from the lungs) (Clark & Watson, 2008; Eysenck & Eysenck, 1985; Lecci & Magnavita, 2013; Noga, 2007). Centuries later, the influential Greek physician and philosopher Galen built on Hippocrates’s theory, suggesting that both diseases and personality differences could be explained by imbalances in the humors and that each person exhibits one of the four temperaments. For example, the choleric person is passionate, ambitious, and bold; the melancholic person is reserved, anxious, and unhappy; the sanguine person is joyful, eager, and optimistic; and the phlegmatic person is calm, reliable, and thoughtful (Clark & Watson, 2008; Stelmack & Stalikas, 1991). Galen’s theory was prevalent for over 1,000 years and continued to be popular through the Middle Ages.

In 1780, Franz Gall, a German physician, proposed that the distances between bumps on the skull reveal a person’s personality traits, character, and mental abilities (Figure). According to Gall, measuring these distances revealed the sizes of the brain areas underneath, providing information that could be used to determine whether a person was friendly, prideful, murderous, kind, good with languages, and so on. Initially, phrenology was very popular; however, it was soon discredited for lack of empirical support and has long been relegated to the status of pseudoscience (Fancher, 1979).

Photograph A shows the cover of the American Phrenological Journal circa 1848. Across the top it reads: “American Phrenological Journal.” Below that it says “Know thyself.” Below that is a picture of a human head facing left, with many pictures comprising the area where the brain is. Below the person’s ear it says “Home truths for home consumption.” The lines below that read: “1848,” “Vol. X, March, No. 3,” “O.S. Fowler, Editor,” “Phrenology, Physiology, Physiognomy, Magnetism,” “New York,” “Fowlers and Wells,” “Phrenological cabinet, 131 Nassau-Street,” and “Terms $1 a year, invariably in advance. Ten cts. a Number.” Photograph B shows a printed cartoon of a person in a chair with another person behind. There are three other people in the room, and the wall is decorated with various skulls. Below the picture it reads: “Drawn on Stone by E.H,” and “The Phrenologist.”
The pseudoscience of measuring the areas of a person’s skull is known as phrenology. (a) Gall developed a chart that depicted which areas of the skull corresponded to particular personality traits or characteristics (Hothersall, 1995). (b) An 1825 lithograph depicts Gall examining the skull of a young woman. (credit b: modification of work by Wellcome Library, London)

In the centuries after Galen, other researchers contributed to the development of his four primary temperament types, most prominently Immanuel Kant (in the 18th century) and psychologist Wilhelm Wundt (in the 19th century) (Eysenck, 2009; Stelmack & Stalikas, 1991; Wundt, 1874/1886) (Figure). Kant agreed with Galen that everyone could be sorted into one of the four temperaments and that there was no overlap between the four categories (Eysenck, 2009). He developed a list of traits that could be used to describe the personality of a person from each of the four temperaments. However, Wundt suggested that a better description of personality could be achieved using two major axes: emotional/nonemotional and changeable/unchangeable. The first axis separated strong from weak emotions (the melancholic and choleric temperaments from the phlegmatic and sanguine). The second axis divided the changeable temperaments (choleric and sanguine) from the unchangeable ones (melancholic and phlegmatic) (Eysenck, 2009).

A circle is divided vertically and horizontally into four sections by lines with arrows at the ends. Clockwise from the top, the arrows are labeled “Strong Emotions,” “Changeable Temperaments,” “Weak Emotions,” and “Unchangeable Temperaments.” The arcs around the perimeter of the circle, clockwise beginning with the top right segment are labeled “Choleric,” “Sanguine,” “Phlegmatic,” and “Melancholic.” The sections inside each arc contain descriptive words. Inside the Choleric arc are the words “excitable, egocentric, exhibitionist, impulsive, histrionic, and active.” Inside the Sanguine arc are the words “playful, easygoing, sociable, carefree, hopeful, and contented.” Inside the Phlegmatic arc are the words “reasonable, principled, controlled, persistent, steadfast, and calm.” Inside the Melancholic arc are the words “anxious, worried, unhappy, suspicious, serious, and thoughtful.”
Developed from Galen’s theory of the four temperaments, Kant proposed trait words to describe each temperament. Wundt later suggested the arrangement of the traits on two major axes.

Sigmund Freud’s psychodynamic perspective of personality was the first comprehensive theory of personality, explaining a wide variety of both normal and abnormal behaviors. According to Freud, unconscious drives influenced by sex and aggression, along with childhood sexuality, are the forces that influence our personality. Freud attracted many followers who modified his ideas to create new theories about personality. These theorists, referred to as neo-Freudians, generally agreed with Freud that childhood experiences matter, but they reduced the emphasis on sex and focused more on the social environment and effects of culture on personality. The perspective of personality proposed by Freud and his followers was the dominant theory of personality for the first half of the 20th century.

Other major theories then emerged, including the learning, humanistic, biological, evolutionary, trait, and cultural perspectives. In this chapter, we will explore these various perspectives on personality in depth.

Summary

Personality has been studied for over 2,000 years, beginning with Hippocrates. More recent theories of personality have been proposed, including Freud’s psychodynamic perspective, which holds that personality is formed through early childhood experiences. Other perspectives then emerged in reaction to the psychodynamic perspective, including the learning, humanistic, biological, trait, and cultural perspectives.
