Abstract
Avoiding pain-associated activities can prevent tissue damage. However, when avoidance spreads excessively (or overgeneralizes) to safe activities, it may culminate into chronic pain disability. Gaining insight into ways to reduce overgeneralization is therefore crucial. An important factor to consider in this is relief, as it reinforces avoidance behavior and therefore may be pivotal in making avoidance persist. The current study investigated whether experimentally induced positive affect can reduce generalization of pain-related avoidance and relief. We used a conditioning task in which participants (N = 50) learned that certain stimuli were followed by pain, while another was not. Subsequently, they learned an avoidance response that effectively omitted pain with one stimulus, but was ineffective with another. Next, one group of participants performed an exercise to induce positive affect, while another group performed a control exercise. During the critical generalization test, novel stimuli that were perceptually similar to the original stimuli were presented. Results showed that both avoidance and relief generalized to novel stimuli, thus replicating previous work. However, increasing positive affect did not reduce generalization of avoidance, nor relief.
