a method of studying heritability by comparing genetic markers that allows researchers to assess how genetic differences interact with environment to produce certain behaviors in some people but not in others
Term
developmental psychology
Definition

explores how thought and behavior change and show stability across the life span.

-allows us to appreciate that organisms change and grow, thus psychological functions likely change as well

Term

-the mind simply receives what our sensory organs-eyes,nose,skin,ears and tongue-experience and take in from the outside is very important in psychology and philosophy.

Term
Introspection
Definition

the main method of investigation for sturcturalists; it involves looking into ones own mind for information about the nature of conscious experience.

 -Wilhelm Wundt coined phrase
