采用听觉通道Oddball范式考察认知期望高低对偏差干扰和偏差后干扰的影响.实验一采用声音方位辨别任务证实了偏差干扰效应和偏差后干扰效应,实验二通过改变靶出现概率操作认知期望水平,结果发现:高期望水平整体反应显著性快于低期望水平;在高标准高偏差和高标准低偏差条件下偏差干扰效应均显著,而偏差后干扰效应消失;低标准低偏差条件下偏差干扰和偏差后干扰均消失;低标准高偏差条件下偏差干扰消失而出现易化作用,而偏差后干扰显著存在.研究认为干扰现象受认知期望的影响.
Oddball paradigm of auditory pathway was used to investigate the effect of cognitive expectation on the bias interference and post-bias interference.Experiment 1 proved the bias interference effect and post-bias interference effect in experiment 1 by using the azimuth discrimination task, and in experiment 2, the cognitive expectation level The results showed that: the overall response of high expectation level was significantly faster than the low expected level; under the high standard deviation and the high standard low deviation conditions, the deviation interference effect was significant, but the post-deviation interference effect disappeared; the deviation interference under the low standard deviation And the deviation after the interference disappeared; deviation under the conditions of low standard deviation disappeared and facilitation, while the deviation of the existence of significant interference.Studies that the interference phenomenon is affected by cognitive expectations.
