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)
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)
Emotion is known to interact with behavioral inhibitory control (BIC), an ability critical for adaptive living. Nevertheless, how emotion valence influences this control, and the spatiotemporal dynamics underlying this influence, remain undetermined. For this purpose, the present study recorded event-related potentials (ERPs) for a standard stimulus which(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)
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)
As an ability critical for adaptive social living, behavioral inhibitory control (BIC) is known to be influenced substantially by unpleasant emotion. Nevertheless, how unpleasant emotion of diverse strength influences this control, and the spatiotemporal dynamics underlying this influence, remain undetermined. For this purpose, Event-related potentials(More)
To explore the temporal features and underlying brain structures of self-referential processing, participants were shown examples of Chinese handwriting, half of which were their own and the other half belonged to others, and asked to judge whether the handwriting was their own. In Experiment 1, the task was to categorize the handwriting by pressing the(More)
This study investigated the impact of auditory-induced emotion on response inhibition. Fifty kinds of positive, neutral, and negative sounds were used as emotional materials whose presentation was followed by a Go/Nogo task. Event-related potentials were recorded for Go and Nogo tones. The response times for Go stimuli were longer under negative than under(More)
We designed a novel task, partially incongruent categorization (PIC), to examine the timing of cognitive control. In the PIC task, participants categorized the probe stimulus according to a specific concept, and the number of features corresponding to the concept was varied. When there was one feature (c1 condition), the probe would elicit only(More)
This study investigated whether the human sensitivity to valence intensity changes in positive stimuli varies with extraversion. Event-related potentials were recorded for highly positive, moderately positive, and neutral stimuli while participants (extraverts and nonextraverts) performed a standard/deviant categorization task, irrespective of the(More)
