The purpose of this research is to study the development of decision-making abilities between educated and non-educated groups, analyzing blood flow changes over the frontal lobes. Neural activation was estimated with infra-red spectroscopy. The educated subjects were of 3 undergraduates majoring in Home Economics with cooking lesson experience, and the non-educated subjects were of 5 other undergraduates not majoring in Home Economics. A task was projected on a screen for 30 s in a series of 30 questionnaires alternatively, composed of educated questions and non-educated questions. And subjects were asked to make a decision as fast as he/she could, and in case of no decision the subjects were asked to no more think. Just after the measuring a comprehension-test was done.The Oxy-hemoglobin dynamics showed different frontal lobe activation between the 2 groups. Education might activate the frontal lobes in decision-making.
