There is considerable evidence that people are especially sensitive to emotionally negative materials. However, the temporal course of the negativity bias is still unclear. To address this issue, we observed the changes of P2, late positive components (LPC) and lateralized readiness potential (LRP) under positive, negative and neutral conditions, with(More)
It has been suggested that anxious individuals are more prone to feel that negative outcomes are particularly extreme and to interpret ambiguous outcomes as negative compared to nonanxious individuals. Previous studies have demonstrated that the feedback negativity (FN) component of event-related brain potential (ERP) is sensitive to outcome evaluation and(More)
Considerable evidence from behavioral studies has indicated that people tend to pay attention to negative stimuli preferentially. The attentional bias can occur rapidly and automatically. In the current study, a 'cue-target' paradigm was utilized to manipulate the attention allocation. Seventeen healthy undergraduates participated in the experiment. The(More)
Patients suffering from anxiety disorder may experience a few problems in the inhibition function. Using event-related potentials, the current study investigated the differences between subjects with high versus low trait-anxiety when they tried to inhibit disturbances in novel emotional pictures in an oddball task. The results showed that P3 amplitudes(More)
The manganse bioleaching mechanism by a manganese-resistant strain Fusarium sp. was investigated, through analyzing the bioleaching rate and manganese-electrolytic residue characterizations with the presence of Fusarium sp. and with the addition of organic acids. Special attention was paid to explore the relationship among the manganese's leaching rate, pH,(More)
Behavioral studies demonstrate that the timing of receiving gains or losses affects decision-making, a phenomenon known as temporal discounting, as participants are inclined to prefer immediate rewards over delayed ones and vice versa for losses. The present study used the event-related potential technique with a simple gambling task to investigate how(More)
The present study described a new type of multi-person neurofeedback with the neural synchronization between two participants as the direct regulating target, termed as "cross-brain neurofeedback." As a first step to implement this concept, an experimental platform was built on the basis of functional near-infrared spectroscopy, and was validated with a(More)
Previous studies have shown that two components of event-related potentials, the feedback negativity (FN) and P300, respond to feedback information of reward and penalty. The present study investigated the response of FN and P300 to neutral (neither reward nor penalty) outcome in an EEG level control task. Reward, penalty and neutral feedbacks were(More)
This study examined the temporal courses of imagery processes by having participants imagining vibrotactile sensation as if perceived by the right-hand second finger. The results indicate that the imagery condition elicited a less negative going N400 and then a less positive going P600 than the control condition (perceived without imagining). This is(More)
1.1 Influence of anxiety on Inhibition function: Emotional processing Many researchers have reported that anxiety patients are more sensitive to emotional stimuli, particularly negative stimuli. This phenomenon is suggested to be linked with highanxiety people’s inhibition dysfunction when facing emotional stimuli (Barkley, 1997; Enright & Beech, 1993).(More)
