阈下和阈上不同情绪启动对反应抑制的影响

The Effect of Two Types of Emotional Priming on Response Inhibition

为检验反应抑制是否受阈下情绪启动的影响,以及进一步验证阈上情绪效价对反应抑制的作用,通过Go-Nogo范式分别在实验一和实验二中以阈下和阈上两种情绪启动方式考察情绪对反应抑制的影响。结果发现阈下情绪启动实验中,负性情绪Go任务下的反应时显著长于正性情绪和中性情绪下的反应时,而正性情绪和中性情绪下反应时之间差异不显著。阈上实验中发现了同样的结果,并且发现负性情绪Nogo任务下的虚报率显著高于正性和中性情绪Nogo任务下的虚报率。对比两种情绪启动条件后发现,阈上情绪启动的Go任务反应时都要显著长于阈下情绪启动对应的反应时。

To test whether the response inhibition was influenced by subthreshold emotional priming and verify the effect of threshold emotional priming on response inhibition,we used the Go-Nogo paradigm task to investigate the relationship between two types of emotional priming and response inhibition through two experiments. The results of subthreshold emotional priming experiment found that the response time of negative emotional priming Go task significantly higher than that of positive and neutral emotional priming Go task,and there was no significant difference between positive emotion and neutral emotion. The same result was found by threshold emotional priming experiment,and the false rate of negative emotional priming Nogo task is significantly higher than that of positive and neutral emotional priming Nogo task. The response time under Go task of threshold emotional priming was significantly higher than that of subthreshold emotional priming.
