In this unit, you studied human personality. One of the things you had to consider is the role human difference plays in the development of personality. However, you also had to consider the role of similarity in determining and theorizing about personality
Trait Theories - Raymond Cattell
Raymond Cattell was a psychologist who developed trait theories of personality. He believed that personality can be understood in terms of a person's traits, which are stable characteristics that influence behavior. Cattell identified 16 source traits that underlie human personality, such as extroversion, neuroticism, and openness. He also identified surface traits, which are the observable behaviors that result from the interaction of source traits.
One of the key aspects of Cattell's theory is the idea of individual differences in personality. He believed that people differ in terms of their level of each trait, and that these differences can help explain why people behave in different ways. For example, someone high in extroversion may be more outgoing and sociable, while someone low in extroversion may be more reserved and introverted.
However, Cattell also recognized the role of similarity in personality. He argued that there are common traits that are shared by all people, such as the need for social interaction and the desire for security. These common traits can help build connections between people and provide a basis for understanding and predicting behavior.
Overall, Cattell's trait theories of personality highlight the importance of both individual differences and similarities in understanding human personality. By considering both aspects, psychologists can develop a more comprehensive and nuanced understanding of how personality develops and influences behavior.
