Antisaccade Cost Is Modulated by Contextual Experience

Temporal dynamics of the consistency effect in reading Chinese: an event-related potentials study.

This study aimed to explore the temporal dynamics of the consistency effect in reading Chinese phonograms. High-consistency and low-consistency characters were used in the homophone judgment task, and the event-related potentials were recorded. The data showed that low-consistency characters elicited greater N170 amplitude in the temporal-occipital region and greater P200 amplitude in the front...

Neural correlates of impulsive-violent behavior: an event-related potential study.

Impulsive-violent offenders are often less capable of controlling their behavior. A cued Go/No-go task was used to test the hypothesis that impulsive-violent behavior reflects a deficit in the ability to inhibit prepotent responses and could be reflected in the measurement of event-related potentials. Results showed that the amplitudes of the N2 component at Fz reflected different degrees of in...

Sex differences in how erotic and painful stimuli impair inhibitory control.

Witnessing emotional events such as arousal or pain may impair ongoing cognitive processes such as inhibitory control. We found that this may be true only half of the time. Erotic images and painful video clips were shown to men and women shortly before a stop signal task, which measures cognitive inhibitory control. These stimuli impaired inhibitory control only in men and not in women, sugges...

Sex differences in spinal excitability during observation of bipedal locomotion.

This study investigated whether there are sex differences in the spinal excitability of the human mirror-neuron system. We measured the modulation of spinal excitability, elicited by Hoffmann reflex in the left plantar flexor muscle (soleus), when women and men participants observed videos of bipedal heel-stepping (plantar dorsiflexion), standing still, and bipedal toe-stepping (plantar flexion...
