The present study investigated whether the human brain is sensitive to valence differences in emotionally negative stimuli by recording event-related potentials (ERPs) for extremely negative (EN), moderately negative (MN), and neutral pictures while subjects perform a standard/deviant categorization task, irrespective of the emotional valence of the(More)
The inhibition of inappropriate behaviors is important for adaptive living in changing environments. The present study investigated gender-related behavioral inhibitory control by recording event-related potentials for standard and deviant stimuli while subjects performed a standard/deviant distinction task by accurately pressing different keys within 1000(More)
Previous studies have extensively reported an advantage of females in identifying negative facial emotions as compared with males. Nevertheless, why females are better in performance relative to males during emotion recognition tasks is still unknown, and the neural mechanism(s) underlying this phenomenon has yet to be directly investigated. As facial(More)
Considerable studies reported that females are more susceptible to affective disturbances such as depression, anxiety disorder, and phobia compared to males. Based on the close relation between emotional sensitivity and liability to affective disturbances (Hofer et al. [2006]: NeuroImage 32, 854-862; Spearing [2001]: Bipolar disorder, 2nd ed. Bethesda (MA):(More)
OBJECTIVE The current model of ADHD suggests abnormal reward and punishment sensitivity, although differences in ADHD subgroups are unclear. This study aimed to investigate the effect of feedback valence (reward or punishment) and punishment magnitude (small or large) on Feedback-Related Negativity (FRN) and Late Positive Potential (LPP) in two subtypes of(More)
The timing dynamics of regulating negative emotion with expressive suppression and cognitive reappraisal were investigated in a Chinese sample. Event-Related Potentials were recorded while subjects were required to view, suppress emotion expression to, or reappraise emotional pictures. The results showed a similar reduction in self-reported negative emotion(More)
How task focus affects recognition of change in vocal emotion remains in debate. In this study, we investigated the role of task focus for change detection in emotional prosody by measuring changes in event-related electroencephalogram (EEG) power. EEG was recorded for prosodies with and without emotion change while subjects performed emotion change(More)
The present study investigated neural correlates underlying the psychological processing of the extent of self-relevance. Event-related potentials were recorded for distracting names different in extent of self-relevance while subjects performed a three-stimulus oddball task. The results showed larger amplitudes and prolonged latencies for high(More)
The present study investigated the electrophysiological correlates of the psychological processing of the collective self-relevant stimulus using a three-stimulus oddball paradigm. The results showed that P300 amplitude elicited by the collective self-relevant stimulus was larger than those elicited by familiar and unfamiliar stimuli. In addition, N250 and(More)
In natural settings, the occurrence of unpredictable infrequent events is often associated with emotional reactions in the brain. Previous research suggested a special sensitivity of the brain to valence differences in emotionally negative stimuli. Thus, the present study hypothesizes that valence changes in infrequent negative stimuli would have(More)
