Kaylee's experience of pain during a demanding physical exercise routine was intensified when she noticed that other exercise participants were in a lot of pain.This best illustrates that the experience of pain is influenced by

A) dissociation.
B) psychokinesis.
C) top-down processing.
D) synesthesia.

Top-down processing refers to the influence of higher-level mental processes, such as cognition and expectation, on the experience of pain. In this case, Kaylee's perception of the pain was intensified because she was influenced by the pain experiences of those around her, suggesting that her pain perception was influenced by her cognitive and social expectations of the situation. Dissociation refers to the reduction or detachment of the experience of pain, psychokinesis refers to the supposed ability to move objects with one's mind, and synesthesia refers to the blending of sensory experiences. None of these concepts are relevant to Kaylee's experience of pain in this context.
