Biological Approach: Genes Linked to Behaviors
Behavioral Genetics
Studies how both genetics and environment contribute to human behavior.
Based on this principle, some people may have genetic "predisposition" towards a behavior, however, without the appropriate environmental stimuli, the gene is not turned on and the behavior is not expressed
Due to the bidirectional nature of behavior (nature vs nurture), genetic research is based largely on correlation studies
