现在采用返回抑制范式所进行的空间非信息线索作用的研究，大多以非线索化位置反应时为参照，发现线索化位置的反应先易化后抑制。后者即返回抑制。本研究采用在返回抑制范式上增设中性线索化条件的方法，发现当靶子可以出现的位置为四个时，相对于中性线索化条件，非线索化位置反应快。这种非线索化位置的易化作用是独立存在的，它能使生物体尽快地对出现在多个非线索化位置的靶子作出反应。 Nowadays, the research on the effect of spatial non-information clues by using the return inhibition paradigm mostly refers to non-clues to the position reaction, and finds that the reaction at the clues position is facilitated and then suppressed. The latter returns inhibition. In this study, a method of adding neutral clues to the return inhibition paradigm was used. It was found that when the number of target positions can be four, the non-clues position responded faster than neutral clumping conditions. The facilitation of such non-clues is independent and enables organisms to react quickly to targets that appear in more than one clueless location.
