摘要

Introduction: The experience of acute pain and pain-related fear negatively impact cognition and behavior; however, little research has examined their impacts on risky decision-making and effort. The present study investigated the effects of acute pain and pain-related fear on risky decision-making and effort during cognitive tests. Method: Levels of pain-related fear were assessed. Healthy participants (n = 146) experienced acute pain induced via cold pressor task, and then were randomly assigned to one of the four conditions to induce pain-related fear: Pain Threat (n = 36), Pain Threat with Control (n = 39), Cognitive Threat with Control (n = 34), and Control (n = 36). Participants then completed measures of effort (Word Memory Test WMT, self-reported effort) and risky decision-making (Iowa Gambling Task IGT, Balloon Analogue Risk Task BART). Results: Collapsed across condition, participants did not learn to decide advantageously on the IGT following an acute pain experience. During the early trials (1-40) on the IGT, participants in the Pain Threat condition made riskier decisions. Higher levels of pain during the cold pressor task predicted less risky decisions on the BART, and participants in the Cognitive Threat with Control condition made less risky decisions. Participants in the Pain Threat with Control condition self-reported lower effort on cognitive tests, yet no group-based differences were seen in WMT performance. Greater pain-related fear predicted greater self-reported effort and better WMT performance, but no effects were seen on decision-making task performance. Conclusions: The experience of pain and the threat of additional pain can lead to changes in risky decision-making and effort on cognitive tasks. This threat of additional pain could activate underlying pain-related fear, creating hypervigilance to and avoidance of pain that affects subsequent task performance. Implications for research and clinical evaluation of acute pain and pain-related fear are discussed.
