Which of Kelly's corollaries is illustrated by a person who sees all experiences as power struggles and refuses to change their attitude?

The modulation corollary in Kelly's Personal Construct Theory refers to the way a person allows their constructs to be altered and adapted based on new experiences. It emphasizes the flexibility of one's constructs to incorporate new information and change over time.

In the scenario described, the individual perceives all experiences as power struggles and maintains a rigid attitude, which indicates a resistance to adapting their constructs. This inflexibility and refusal to change their attitude highlight a failure to utilize the modulation corollary effectively. Instead, the person clings to their existing views without allowing for modifications, demonstrating a lack of openness to new experiences that could challenge or expand their existing framework of understanding.

The focus here is on the rigidity of the individual’s constructs and their unwillingness to adapt based on interaction with the environment, which directly aligns with the nature of the modulation corollary. The other corollaries do not capture this essence of rigidity and inability to adjust personal understanding as effectively.
