摘　　要：结合数数任务和情绪flanker任务,探究不同认知负载条件下,高低趋近动机对情绪刺激加工的影响。结果发现:高负载组中,高趋近动机条件下,对积极目标刺激的反应显著快于消极目标刺激;低趋近动机条件下,对消极目标刺激的反应显著快于积极目标刺激。且高负载组中,各条件下的反应大多都显著慢于低负载组。低负载组中没有发现各条件之间的差异。结果表明,高负载条件下,高趋近动机促进了积极情绪刺激的加工,低趋近动机促进了消极情绪刺激的加工,高负载在一定程度上阻碍了情绪刺激的加工。The main purpose of the present study was to investigate the effect of motivation on emotional stimulus processing under different cognitive load conditions by combining the emotional flanker task with the number task.The present study used pictures with different emotional dimensions of valence as the target stimuli and pictures with different emotional dimensions of motivation as the interference stimuli.The present study included two experiments both using a 2(cognitive load:high vs.low)×2(the motivation of interference stimuli:high vs.low)×2(the valence of target stimulus:positive vs.negative)mixed design.The procedure of the two experiments was the same one.At the beginning of each experiment,a random number was presented at the center of the screen(two digits under the low cognitive load,three digits under the high cognitive load).Participants were asked to remember this number,keep counting from this number and report loudly(take the number to plus 2 under the low cognitive load condition,reduce 6 under the high cognitive load condition)in the following flanker task.In the flanker task,participants’main task was to ignore the pictures presented on one side of the screen and evaluate the valence of well-defined emotional stimuli(words in Experiment 1 and pictures in Experiment 2)as quickly as possible by pressing the"J"key for positive stimuli and the"F"key for negative stimuli.Experiment 1 used positive/negative words as target stimuli and pictures with high/low motivation as the interference stimuli.Results showed that there was a significant interaction among the cognitive load,the valence of target stimulus and the motivation of interference stimuli.Under the high cognitive load condition,the response times(RTs)were shorter for positive words compared to negative words in the high motivation condition,while the RTs were shorter for negative words compared to positive words in the low motivation condition.However,no significant difference was found under the low cognitive load condition.That was to s
