Attentional capture by task-irrelevant fearful faces is revealed by the N2pc component
We measured the N2pc component as an electrophysiological indicator of attentional selection to investigate whether fearful faces can attract attention even when they are entirely task-irrelevant and attention is focused on another demanding visual monitoring task. Participants had to detect infrequent luminance changes of the fixation cross, while ignoring stimulus arrays containing a face sin...
متن کاملThe N2pc component and stimulus duration.
The N2pc component of the event-related potential is a moment-by-moment index of the deployment of visual-spatial attention. It is not clear whether the N2pc reflects pure top-down attentional activity or a positive interaction of top-down activity with bottom-up sensory activity. Here, we presented a bilateral visual display containing a target and a distractor for a duration of 50, 200, or 35...
متن کاملa study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
Visual search and the N2pc in children
While there is growing understanding of visual selective attention in children, some aspects such as selection in the presence of distractors are not well understood. Adult studies suggest that when presented with a visual search task, an enhanced negativity is seen beginning around 200 ms (the N2pc) that reflects selection of a target item among distractors. However, it is not known if similar...
متن کاملThe Speed of Serial Attention Shifts in Visual Search: Evidence from the N2pc Component
Finding target objects among distractors in visual search display is often assumed to be based on sequential movements of attention between different objects. However, the speed of such serial attention shifts is still under dispute. We employed a search task that encouraged the successive allocation of attention to two target objects in the same search display and measured N2pc components to d...
