This study examined hemodynamic brain activity while cutting wood according to different teaching methods. We used near-infrared spectroscopy, which is a brain activity measurement device. Participants were divided into 2 groups. Two types of experiment were carried out in each group. Group 1 cut wood after being given instructions in the first experiment and repeated this in the second experiment. Group 2 cut wood without the instructions in the first experiment and cut it again after instructions had been given in the second experiment. Both cutting results and the concentration changes of oxy-hemoglobin were measured. Comparing the first experiment with the second (a within-groups comparison), the concentration of oxy-hemoglobin in Group 2 increased in the frontal area, including the presupplementary motor area, the right dorsolateral prefrontal cortex, the left dorsolateral prefrontal cortex, and the frontal pole. These results suggest that frontal cortex activation might be due to different teaching methods.
