Final answer:
An external event is informational within the Cognitive Evaluation Theory if it provides useful information for competence and self-determination, enhancing one's self-efficacy and intrinsic motivation.
Step-by-step explanation:
According to the Cognitive Evaluation Theory, when we say that an external event is informational, it means that it provides information that is useful for competence and self-determination. This contrasts with a controlling aspect of an event, which relates to regulation and possible manipulation of behavior. The informational aspect is seen as playing a positive role in promoting autonomy and competence by giving feedback that helps individuals understand and master their environment. For instance, positive feedback on a task can enhance a person's self-efficacy and intrinsic motivation, which are important cognitive factors in learning and personality development. Self-efficacy greatly influences how challenges are approached and the persistence through setbacks, while the locus of control determines if individuals attribute their successes or failures to internal or external factors.
