Jerome Kagan - On Temperament

The video explores the study of temperamental differences in children, initially resisted by the speaker due to a focus on environmental influences. Through research, the speaker identifies biological differences, particularly in infants' reactions to unfamiliar stimuli, linked to the amygdala. The study categorizes infants into high and low reactive types, correlating with introversion and extroversion. Long-term effects show that while external behavior can change, internal tendencies remain. The video concludes with examples of famous figures and encourages further research in this field.
