掩蔽启动范式中,当掩蔽刺激与目标刺激的时间间隔达到100~200ms时,出现负相容效应。负相容效应是指相容条件的反应时大于不相容条件,错误率高于不相容条件。目前主要有三种理论来解释负相容效应的发生机制,分别是自我抑制理论、目标更新理论和掩蔽抑制理论。三种理论探讨了负相容效应发生的机制,即负相容效应发生在知觉阶段还是反应阶段,涉及自我引发抑制还是刺激引发抑制。有关负相容效应发生的机制还需进一步的探讨。
In masked prime paradigm,negative compatibility effect,with performance benefits on incompatible trials and cost on compatible trials,occurs when mask-target SOA is 100 to 200ms.This effect can be interpreted by three theories:self-inhibition theory,object-updating theory and mask-triggered inhibition theory.All of which probe into the mechanism of negative compatibility effect,including whether it occurs in perception stage or response stage and involves self-inhibition or stimuli-triggered inhibition.The mechanism of negative compatibility effect need to be further explored.
