Final answer:
George Kelly's theory indicates that an individual's behavior is guided by personal constructs, expectations, and interpretations of their environment.
Step-by-step explanation:
In George Kelly's theory, what guides a person's behavior? The answer is A) The constructs an individual has and his/her expectations and interpretations of the environment. Kelly posited that personal constructs, which are the ways in which individuals interpret the world and predict events, are the primary determinants of behavior. Unlike traits viewed through The Big Five personality factors—openness, conscientiousness, extroversion, agreeableness, neuroticism—Kelly believed that our individual constructs guide how we perceive situations and thus influence our behavior. These constructs are formed through experience and are unique to each person, influencing how they approach different scenarios and interpret their environment.
