3.Psychological Factors
These include our motives, acquired interests, our attitudes, our will and character, our intellectual capacities such as intelligence i.e., the abilities to perceive, to observe, to imagine, to think and to reason
These factors determine our reactions in various situations and thus affect our personality, growth and direction. An individual with a considerable amount of will power will be able to make decisions more quickly than others.
Thus, we see that hereditary, environmental and psychological factors contribute towards the development of personality.
