Final answer:
The model that assumes maladaptive ways of feeling, thinking, and behaving may have been learned is the Cognitive-Behavioral model of pain. This model is closely related to learning through environmental interactions and the therapeutic approaches to modify such behaviors.
Step-by-step explanation:
The assumption that maladaptive ways of feeling, thinking, and behaving may have been learned is part of the Cognitive-Behavioral model of pain. This approach posits that individuals learn behaviors and thought patterns through their interactions with the environment, which can contribute to their experience of pain. Thus, cognitive-behavioral therapy (CBT) often involves strategies to unlearn these maladaptive ways and replace them with healthier coping mechanisms.
