Final answer:
The main idea of reciprocal determinism is option (c) "Our behavior, cognitive processes, and situational context all influence each other," which is a theory by Albert Bandura stating that these three factors have a reciprocal cause-and-effect relationship.
Step-by-step explanation:
The statement that summarizes the main idea of reciprocal determinism is option c. Reciprocal determinism is a concept introduced by Albert Bandura, and it suggests that behavior is not just influenced by the environment, but there is a continuous interactive relationship between an individual's behavior, personal factors (such as cognitive skills, attitudes, and biological events), and the environment.
Bandura's view contrasts with earlier theories by Skinner, which emphasized that the environment alone shapes behavior and Freud's view that personality is fixed in childhood. In reciprocal determinism, cognitive thinking, such as an individual's beliefs or personalities, can shape how they interact with their environment and vice versa.
