Definition:
Temperament refers to our inborn personality traits, which are genetic in nature. The different ways infants interact with and react to the their environment and experiences are reflective of their temperament, or behavioral style.
In general, temperaments exist as they are prior to birth and are a component of an individual’s personality. Although it is thought that temperaments are genetically determined, personalities as a whole are a combination of temperaments and experiences that shape and influence a person’s development.
