AP PSYCH 7.5 Introduction to Personality
- Personality is the characteristic pattern of a person’s thinking, feeling, and behavior
- Personality is often the result of interplay between nature and nurture
- Recall that nature is genetics that determines behavior, and is fixed at birth
- Nurture is our environment and upbringing, as well as the constant effect that experiences have
- Personality theories attribute different levels of influence to either
- We will also revisit heritability, which does not indicate what proportion of a trait is determined by nature/nurture, nor is it the extent to which traits are passed down
- Heritability is the variability in the trait in a population that is due to genetic differences, often estimated from studies of twins
- Or to what degree do differences in genes account for differences in our personality traits
- Personality is measured through a variety of tests with different approaches and methodologies
- It is always important to consider the validity and reliability of these measures
