Abstract

Backward-masking conditions were established for a pair of circularpatch stimuli. A third stimulus was then selected so as to mask the second when the second and the third were presented in the absence of the first. When all three stimuli were presented in serial order, the first and third were reliably detected but the second was not. Apparently, by masking the second flash, the third "disinhibited" the first.

摘要

针对一对圆形斑块刺激建立了后向掩蔽条件。然后选择第三个刺激，以便在第一个刺激不存在的情况下呈现第二个和第三个刺激时，第三个刺激能够掩蔽第二个刺激。当按顺序呈现所有三个刺激时，第一个和第三个刺激能够被可靠地检测到，而第二个刺激则检测不到。显然，通过掩蔽第二个闪光，第三个刺激“解除了对”第一个刺激的“抑制”。
