COLLOQUIUM HEYMANS INSTITUUT

Time: 1200 - 13.00 hrs.
Room: M 161 (Kouwerzaal), Muntingbuilding, Groningen
Abstract:
Event-related brain potentials, or the time-locked recording of electrical activity in the brain, can allow us much insight on issues of person perception, stereotyping, and prejudice. ERPs have excellent temporal resolution, which can show the unfolding of different processes across time as well as allow us to examine the effects of sequential processing stages on behavioral outcomes. This talk will describe several studies that have begun to examine the process of person perception using ERPs. First, several studies will examine the surprisingly early influence of social category information, and show that ERPs discriminate between members of different social categories as early as 100ms after stimulus presentation. The effect of stereotypes on reaction time tasks will then be examined, and evidence presented that African-American targets are particularly likely to draw attention (as measured by attentional-related ERPs) in a stereotype-congruent environment, and that this attentional bias predicts biased reaction times. Furthermore, these targets are also less likely to cause individuals to engage in corrective processing when an erroneous response is made. Implications of these findings for models of person perception and automatic stereotype activation will be considered.
