3093.1 Effect of spatial and non-spatial cue on target identification: An ERP study, Xuemin
Zhang, Yongna Li, Beijing Normal University, China
The present study used spatial cueing paradigm to research the effect of spatial and non-spatial cue
on target identification. The behavioral study showed that spatial cue had significant effect on
target identification. Non-space cue has no cue effect. We did a further ERP study based on the
previous behavioral study. The ERP study showed that spatial and non-spatial cue had different
effect on cue-evoked event-related potentials (ERPs). These results were consistent with the
behavioral study in some way. These results also supported Matin’s results and Simon and other
researchers’ SRC theory. The detailed results will report at the presentation.
3093.2 Flanker effects in emotional faces identification, Chunping Jiang, XiaoLin Zhou,
Peking University. China
In standard flanker paradigm, RT and accuracy to centrally targets can be altered by the
task-irrelevant (flankers). In this study, the emotional faces were used as target and participants
judge they are positive or negative expression, flankers are morphs between positive and negative
emotion for different pixel. It was found that it lead to faster and more accurate responses when
emotional faces are congruent than incongruent when the target are negative emotion, whereas no
such effect in positive faces. The interpretation advanced is that: negative emotion should capture
attention enhance perceptual processes and competition in selection processes.
3093.3 What occurs after the initial selective attention to negative words: Test the pattern of
attentional bias by manipulation of stimuli exposure times, Xinghua Liu, Mingyi Qian, Xiaolin
Zhou, Peking University, China
The study investigated the vigilance-avoidance pattern of anxiety-related attentional bias for
negative words by manipulating stimuli exposure times. High and low anxious individuals carried
a modified dot-probe task (N = 47). Words pair were presented for eight times, and each time the
attentional bias were examined. High anxious individuals showed selective attention to negative
words when presented for the first time. However, the pattern of attentional bias changed when
stimulus were presented in the first three times; and then the reaction time was no longer
influenced by word meaning when stimulus were presented more times. Theoretical and
methodological implications are discussed.
3093.4 Affective and cognitive processing among problem and non-problem drinkers in a
modified Stroop task, Dinkar Sharma 1 , Ian P. Albery 2 , Ana Fernandez 1 , 1 University of Kent,
UK; 2 South Bank University, UK
Biases in processing alcohol stimuli in problem drinkers have been characterised as automatic.
This suggests these biases are fact acting. Using a modified Stroop task with problem and
non-problem drinkers we show that such biases can be relatively fast, operating online during
stimulus presentation (online component) and relatively slow, operating offline beyond stimulus
presentation (initial offline and persistent offline). In problem drinkers the interference from
alcohol and emotional words that are present online is shown to be predicted by a non-affective
factor (ratings of alcohol relatedness). In contrast an affective factor (ratings of emotionality)
predicted interference for the initial offline component. These results suggest that the
cognitive/non-affective effects operate prior to any emotional effects.
