What Causes Trait Differences? (Intro Psych Tutorial #140)

www.psychexamreview.com In this video we consider why traits might differ between people, beginning with the possible role of biological systems. Hans Eysenck suggested that introverts and extraverts differed in their levels of cortical arousal, resulting in different needs for stimulation that influence behavior. Next we look at the behavioral approach system and the behavioral inhibition system, two opposing systems of brain activity which roughly correspond to positive and negative emotion. Differences in activity and responsiveness of these two systems may explain some personality differences. Personality and its Transformations Course Lectures - Jordan B.
