目前的囤积障碍（HD）模型强调决策问题。然而，HD患者神经心理损害的证据却众说纷纭。目前的研究考察了HD患者是否表现出与决策问题相关的经济推理问题。42名HD患者，29名强迫症患者和36名健康对照组参与者完成了爱荷华赌博任务（IGT），这是一种电脑纸牌游戏，评估参与者学习和利用牺牲短期利益换取长期利益的规则的能力，以及认知失调减少任务，测量参与者在选择或拒绝物品（艺术印刷品）后对它们的偏好变化。结果显示，HD参与者在IGT上没有缺陷，在选择和拒绝项目后，在减少失调任务上的结果没有差异。此外，这两项任务的表现与囤积症状的严重程度或自我报告的优柔寡断无关。这表明，HD患者的认知加工问题可能在很大程度上与尚未充分研究的过程有关，包括个人拥有物品的特殊分类问题以及经济推理的其他方面。
Current models of hoarding disorder (HD) emphasize problems of decision-making. Evidence for neuropsychological impairment in HD, however, has been mixed. The present study examined whether HD patients show problems of economic reasoning that could be associated with decision-making problems. Forty-two HD patients, 29 obsessive-compulsive disorder (OCD) patients, and 36 healthy control participants completed the Iowa gambling task (IGT), a computerized card playing game that assesses participants’ ability to learn and utilize a rule of sacrificing short-term gain for long-term gain, and a cognitive dissonance reduction task that measured changes in preference for items (art prints) after selecting or rejecting them. Results showed no deficits on the IGT for HD participants, and no difference in dissonance reduction results after selecting or rejecting items on the dissonance reduction task. Furthermore, performance on these two tasks was unrelated to hoarding symptom severity or self-reported indecisiveness. It is suggested that the problems of cognitive processing in HD patients may be largely related to as-yet understudied processes, including idiosyncratic categorization problems for personally-owned items as well as other aspects of economic reasoning.
