Question no. 1 Cognition is the mental process of acquiring knowledge through thinking, judgment, and problem solving. Cognitive function provides humans with the ability to use language, create perceptions, use imagination, and make decisions. These thought processes play a significant role in personality development. Both biological and environmental factors have been linked to cognition. Biological factors include our genetic makeup and hereditary factors. Genetic composition determines the physical characteristics of eye color, hair color. Hereditary factors are those traits that are transferred from parents and blood relatives. These hereditary traits determine the temperament of human beings. Both biological traits of genetics and heredity play an important role in how humans perceive themselves and how others interact with them. This cognitive perception of oneself and others is believed to help determine one's personality. Environmental factors include how a human being is raised and how external influences such as school, church, relationships, and society shape his or her cognitive processes. An example of the relationship between cognition and personality would be that of a child born to two different races. Physical characteristics are likely to be different in mixed races, causing the child to perceive himself or herself as abnormal, thus leading to antisocial or withdrawn personality traits.
