Visual sensitivity can be heightened in the vicinity of an appropriate precue. Experiments with multiple, noninformative precues suggest that this facilitation should not be attributed to focal attention. The number of simultaneously appearing precues seems to be irrelevant; contrast thresholds are lowest for targets that appear in a precued position. Here we report that precues become less effective when they and the target are delivered to different eyes. We conclude that the mechanism responsible for such heightened sensitivity has largely monocular input.
在适当的预提示附近，视觉敏感度可以提高。对多个无信息预提示的实验表明，这种促进作用不应归因于焦点注意力。同时出现的预提示数量似乎无关紧要；出现在预提示位置的目标的对比度阈值最低。我们在此报告，当预提示和目标传递到不同眼睛时，预提示的效果会降低。我们得出结论，负责这种敏感度提高的机制主要有单眼输入。
