The present study was designed to test whether OC tendencies are associated with indecisiveness and increased need for objective feedback in vague decision situations. This hypothesis was tested using a neutral color judgment task that places minimal demands on working memory.
Sixty-one participants completed several measures of OC symptoms and tendencies. Indecisiveness was tested on a novel computerized task in which participants can move along a continuum marked by two colors at the extreme ends and are instructed to choose the color they judge to be the exact mid-point on the continuum.
OC scores were positively correlated with indecisiveness on the task, as assessed by the amount of time it took participants to complete the task and the extent of their search through the color continuum. This association was most pronounced when feedback for performance was not routinely provided. Requests for feedback were also positively correlated with OC scores. OC scores were not associated with actual performance on the task (accuracy levels) or with confidence ratings.
The study relies on non-clinical participants and the extent to which these results would extend to OCD patients in unknown. Some effects may be confounded by the fixed order in which the task phases were administered.
The findings support the hypothesis that OC tendencies are associated with general indecisiveness and reliance on external feedback.
本研究旨在测试 OC 倾向是否与模糊决策情境中的犹豫不决和对客观反馈的需求增加有关。该假设通过使用对工作记忆要求最低的中性颜色判断任务进行了测试。
61 名参与者完成了几项 OC 症状和倾向的测量。在一项新颖的计算机任务中测试了犹豫不决，在该任务中，参与者可以沿着两个极端颜色标记的连续体移动，并被指示选择他们判断为连续体上确切中点的颜色。
OC 分数与任务中的犹豫不决呈正相关，这可以通过参与者完成任务所需的时间以及他们在颜色连续体上的搜索程度来衡量。当常规不提供绩效反馈时，这种关联最为明显。对反馈的请求也与 OC 分数呈正相关。OC 分数与任务的实际表现（准确率）或置信度评级无关。
该研究依赖于非临床参与者，这些结果在 OCD 患者中会有多大程度的扩展尚不清楚。一些影响可能会受到任务阶段固定顺序的混淆。
研究结果支持 OC 倾向与一般犹豫不决和对外部反馈的依赖有关的假设。
