Final answer:
George Kelly's theory of personality attributes individual differences to biology, socialization, and cognitive processes, but not predominantly to emotions.
Step-by-step explanation:
According to George Kelly's theory of personality, individual differences in personality can be traced to various sources such as biology, socialization, and cognitive processes. However, Kelly did not emphasize emotions as a source of these differences. In the context of social psychology, the focus is often on situational factors, and the social-cognitive theory introduced by Albert Bandura suggests that both cognition and learning significantly contribute to individual differences in personality. From a sociological perspective, numerous factors influence a person's socialization, including gender and class, but Kelly's psychological perspective doesn't attribute a primary role to emotions specifically.
