Q. Effect of heredity and environment on the development of personality. Ans.
What is Personality?
Personality can be defined as a dynamic and organized set of characteristics possessed by a person that uniquely influences his or her cognitions, motivations, and behaviors in various situations. Some say that personality is inherited or hereditary. Some raised the idea that it is environment that shapes one’s personality. Both are correct, many studies have shown that both heredity and environment are responsible in shaping an individual’s personality. Heredity is one of the major factors in the development of our personality. Hereditary factors were passed by our parents and ancestors to us. The individual’s talent and some other traits are just few examples of these traits. The environment is another factor in personality development. These include the place we live and the people around us. Our experiences in our day to day life, as well as the people whom we associated with such as our family, friends, people in the school, in the church and the community as a whole, all influences our personality. Behavioral and Social Cognitive Theories suggest that personality is a result of interaction between the individual and the environment. Behavioral theorists include B. F. Skinner and Albert Bandura. Biological and Evolutionary Approaches to Personality suggests that important components of personality are inherited. Research on heritability suggests that there is a link between genetics and personality traits. One of the best known biological theorists was Hans Eysenck, who linked aspects of personality to biological processes. For example, Eysenck argued that introverts had high cortical arousal, leading them to avoid stimulation. On the other hand, Eysenck believed extroverts had low cortical arousal, causing them to seek out stimulating experiences. Some researchers contend that specific genes are related to personality. For example, people with a longer...
