心理生理反应被认为是病理性赌博（PG）发展中的一个介导因素，并且PG与赌博期间的不同唤醒水平相关。然而，很少有人知道具体的心理生理反应的胜利和失败的PG。本研究调查的心率（HR）和皮肤电导反应（SCR）在爱荷华州赌博任务（IGT）在成人PG组（它= 46）和正常对照组（NC）（n = 47）。在IGT和心理生理反应的胜利和失败的不利和有利的选择预期的心理生理反应进行了测量。PG组在IGT上的表现比NC组差，并且在IGT期间考虑不利的卡片组的选择时表现出较低的预期SCR和HR降低。PG组在输后和赢后HR下降，而NC组在输后HR下降，但在赢后HR增加。通过自我报告的BIS/BAS量表测量的奖励和惩罚敏感性影响IGT表现和心理生理反应。但一般来说，PG组和NC组的这些作用相似。PG中对不利选择的预期心理生理反应较低，表明该组的风险评估受损。没有一个HR增加后，胜利可能意味着奖励的敏感性降低PG。因为奖励和惩罚的敏感性水平与差异预期HR反应有利和不利的甲板，这将是明智的，包括这种分类的心理生理反应的奖励和损失的研究。(c)2006爱思唯尔爱尔兰有限公司保留所有权利。
Psychophysiological responses are considered to be a mediating factor in the development of pathological gambling (PG) and PG has been associated with differential arousal levels during gambling. Yet little is known about the specific psychophysiological responses to wins and losses in PG. This study investigated heart rate (HR) and skin conductance responses (SCRs) during the Iowa Gambling Task (IGT) in an adult PG group (it = 46) and a normal control (NC) group (n = 47). Anticipatory psychophysiological reactions to disadvantageous and advantageous choices during the IGT and psychophysiological responses to wins and losses were measured. The PG group performed worse than the NC group on the IGT and exhibited lower anticipatory SCRs and HR decreases when pondering choices of disadvantageous card decks during the IGT. The PG group showed a decrease in HR after losses and wins, whereas the NC group showed a decrease in HR after losses, but an increase in HR after wins. Reward and punishment sensitivity as measured by the self-report BIS/BAS scale influenced IGT performance and psychophysiological responses. but in general these effects were similar for the PG group and the NC group. Lower anticipatory psychophysiological responses to disadvantageous choices in PG suggest impaired risk assessment in this group. Absence of a HR increase after wins possibly implies that reward sensitivity is decreased in PG. Because levels of reward and punishment sensitivity were associated with differential anticipatory HR responses to advantageous and disadvantageous decks, it would be advisable to include this taxonomy in studies on psychophysiological responses to rewards and losses.
