知觉中的关系动力学:对试验间变异的影响

Relational Dynamics in Perception: Impacts on trial-to-trial variation

Shimon Marom, Avner Wallach

摘要:

我们表明,审判到审判的变化,而不是呈现一个固定的刺激对比度时,在一个受试者的判断波动相匹配的刺激对比度的波动,在一个微弱的视觉刺激的感官检测显着减少。这种波动的衰减不涉及受试者心理测量功能的变化。这一结果与将这种感觉检测任务中的试验间差异解释为一种高级元认知控制过程相一致,该过程探索了我们的大脑非常习惯的东西:主体-客体关系动态。

英文摘要:

We show that trial-to-trial variability in sensory detection of a weak visual stimulus is dramatically diminished when rather than presenting a fixed stimulus contrast, fluctuations in a subject's judgment are matched by fluctuations in stimulus contrast. This attenuation of fluctuations does not involve a change in the subject's psychometric function. The result is consistent with the interpretation of trial-to-trial variability in this sensory detection task being a high-level meta-cognitive control process that explores for something that our brains are so used to: subject-object relational dynamics.
