Explanation:

Kelley’s theory is an attribution theory that explains how people’s social perception and self-perception are formed by making attributions to causes of events, which in turn influence how they interact with others. These attributions, can be categorized as internal or external. People’s behaviors can be attributed to be as a result of personal factors that are internal, such as traits, feelings, or ability. On the other hand, behaviors of people can be attributed to be as a result of social or environmental factors which are external.
