PS330: Personality Development
Prof: Benjamin Anderson
1. What is the relationship between cognition and personality development?
Put simply, developmental theories of personality follow quite closely the same developmental timetable as cognitive development. The Oral stage of Freud occurs during the Sensor motor period of Piaget; the anal stage, Pre-conceptual stage; the phallic stage, Concrete Operational Stage; the Latency period of Freud also occurs during the Concrete Operational stage; the Genital stage, Formal Operations. Erickson’s stages ad other stage theories follow a similar path. The ages of these stages are also milestones in development, many relating to a child’s focus in relationship to the world and an increasing divestiture of egocentrism with a better understanding of the self and the relationship of the self to others (Schultz, & Schultz, 2008). Cognition is a person’s competencies to describe what they are able to do. Knowing that one can perform a certain behavior does not mean that they will do so. (Cloninger, Friedman, & Schustack, 2010, page 373)
Behavioral and physiological research generally supports Eysenck’s view. When introverts and extraverts are presented with a range of intense stimuli, introverts respond more strongly, including salivating more when a drop of lemon juice is placed on their tongues and reacting more negatively to electric shocks or loud noises (Bartol & Costello 1976; Stelmack, 1990). This reactively has an impact on the ability to concentrate. Extraverts tend to perform well at tasks that are done in a noisy, arousing environment, such as bartending or even teaching, where introverts are better in tranquil surroundings (Schacter, Gilbert, & Wegner, 2009)
2. Explain how evolutionary, biological/genetic, and environmental (i.e. learning) factors can result in the development of an aggressive personality.
