| 概要 | Affect is difficult to measure because it is an activity that occurs deep within the brain. Since, the limbic system and the thalamus, are connected via the cerebral cortex, we indirectly assessed affect by measuring activity in the auditory cortex using MEG. We measured 20 Hz-ASSR (Auditory Steady State Response) from the auditory cortex when participants were presented with a continuous optimized chirp and three emotionally evocative IAPS in a random visual presentation. The mean amplitudes of the ASSRs when these three categories were presented were compared. The result showed a significant difference in ASSR mean amplitude between HAHV and HALV (p<0.05). The results suggested the possibility that affect can be assessed from activity in the auditory cortex. |
