Abstract: The purpose of this study was to examine hemodynamic brain activity while sawing wood based on having or not having failure recognition, i.e., accuracy and surface quality of sawing. Participants were divided into a “failure recognition group” and a “non-failure recognition group.” All participants sawed wood without instructions in the first experiment. Afterward, only participants in the “failure recognition group” received feedback on failure in the task and were asked to reflect on the reason for the failure. In the second experiment, participants in both groups sawed wood again after receiving instructions regarding gaze and head position during sawing. The results revealed that the number of significant channels in prefrontal cortex blood flow was greater in the failure than in the non-failure recognition group (p<.05), even after repeated experiments. The findings suggest that prefrontal cortex activation may be attributed to failure recognition.
