Final Answer:
The theory that suggests you can change a person's interest in exercise is the "Theory of Planned Behavior" (TPB).
Step-by-step explanation:
The Theory of Planned Behavior (TPB) is a psychological model that proposes individuals are more likely to engage in a behavior, such as exercise, if they have a positive attitude towards it, perceive social pressure to engage in it, and believe they have control over it. The TPB suggests that by influencing these three key factors—attitude, subjective norm, and perceived behavioral control—one can positively impact an individual's intention and motivation to participate in exercise.
For example, interventions that enhance positive attitudes towards exercise, emphasize social approval for engaging in physical activity, and promote a sense of control over one's ability to exercise can effectively change a person's interest in physical activity.
A visual representation of the TPB typically involves three main components: 1) Attitude, 2) Subjective Norm, and 3) Perceived Behavioral Control, all leading to the central construct of Behavioral Intention. Behavioral Intention, in turn, influences the actual behavior, which, in this context, is engaging in exercise.
The TPB diagram visually illustrates the interconnectedness of these factors and how they collectively shape an individual's decision to participate in exercise, offering a comprehensive understanding of the psychological processes involved in behavior change.
