It is well known that subjects tend to misattribute task-irrelevant signals, incorporating them into the information on which a decision is made. Such misattribution has been reported to originate only from a social or a cognitive stage of information processing. However, we provide the initial evidence that misattribution also originates at a lower, visuomotor stage. This type of misattribution occurs only when subjects do not notice a visuomotor conflict. Misattribution at a social or a cognitive stage facilitates decision-making if the misattributed information is consistent with the decision and impedes decision-making if the information is in conflict with the decision. However, misattribution originating at a visuomotor stage only impedes decision-making, suggesting a fundamental difference between the mechanisms for the two types of misattribution. Furthermore, misattribution effects that originate in a visuomotor interaction stage also affect subjective preference ratings, suggesting that the misattribution exerts an influence on global brain processing.
众所周知，主体往往会错误归因于与任务不相关的信号，并将其纳入决策所依据的信息中。这种错误归因仅被报道来源于信息处理的社会或认知阶段。然而，我们提供了最初的证据表明，错误归因也起源于较低的视动阶段。只有当主体没有注意到视动冲突时，才会发生这种类型的错误归因。如果错误归因的信息与决策一致，则在社会或认知阶段的错误归因会促进决策，如果信息与决策冲突，则会阻碍决策。然而，起源于视动阶段的错误归因只会阻碍决策，这表明两种类型的错误归因的机制存在根本差异。此外，起源于视动相互作用阶段的错误归因效应也会影响主观偏好评分，这表明错误归因会对大脑的整体处理过程产生影响。
