Figure 3. Signal Detection analysis of subjects' self recognition performance.

Proportion of view-self trials in which subjects correctly identified their hands (Hits) vs. incorrectly judged them to belong to someone else (Misses) and proportion of the view-other trials in which the subjects correctly judged the viewed hands to be someone else's (CR - Correct Rejections) vs. incorrectly judged them to be their own (FA - False Alarms). Note that there were more errors in the passive relative to the active condition, indicating that the task was more difficult when subjects were not the authors of the viewed movement.
