“…This quick and transient difference may not be identified by fMRI studies with lower temporal resolution. Regarding the after effect, no difference was observed, which was different from Muta & Koshikawa (2015) reporting that answering The Positive and Negative Affect Schedule (Watson et al, 1988) in advance influenced the reaction time of a subsequent emotional word discrimination task. This result may suggest either that was a difference in reaction time but not in brain activity, or that the after effect did not occur in the first place in the present task.…”

“…This study also seeks to provide neuroscientific evidence of self-focused attention, which directs attention to one's own emotions and internal changes. Muta & Koshikawa (2015) reported that pre-mood measurement may influence the reaction time of a subsequent emotion word discrimination task. They discussed that prior mood measurement elicited selffocused attention and delayed the response to the stimulus as the reason for this result.…”

In this research to assess emotions from biometric signals, participants are asked to evaluate the emotions they subjectively experienced in order to confirm whether the assumed emotions were actually elicited. However, the evaluation of emotions is not routinely performed in daily life, and it is possible that this evaluation may alter biological signals. In fMRI studies, evaluation has been shown to activate the amygdala, which is said to be related to emotional expression. However, electroencephalography (EEG) studies do not take into consideration the effects of such evaluations, and it is unclear how these evaluations affect emotion-related brain activity observed in EEG. We hypothesized that emotion evaluations would amplify emotions and c alter Frontal Alpha Asymmetry (FAA), which has been shown to be related to emotional pleasantness and unpleasantness. We suspect this is because in order to evaluate one's emotions, one must pay attention to one's internal state, and this self-focused attention has been found to enhance the subjective emotional experience. We measured a 29-channel EEG when presented with unpleasant and highly arousing images from the International Affective Picture System (IAPS) from 40 healthy male and female participants. The results revealed that FAA was significantly lower in the condition in which participants rated their own emotions compared to the condition in which they did not. Similar to fMRI studies, this result indicates that emotion-related brain activity is amplified on an EEG. This paper provides a cautionary note regarding the use of such evaluations in EEG emotion estimation studies.
