如果在该位置或其同侧出现非信息性提示，则中心凹外位置的检测反应时间 (RT) 可能会增加。这种提示诱导的抑制称为返回抑制或同侧抑制。我们测量了对中心凹外位置的简单光目标的检测 RT，这些目标可以通过本地或远处的线索指定为隐蔽定向。我们发现，线索诱导的抑制以累加的方式与隐蔽定向的直接影响同时发生，即，它降低了有人值守位置的便利性，并增加了无人值守位置的劣势。因此，提示诱导的抑制不能通过定向到提示位置的意志隐蔽来抑制；不同促进和抑制效应的同时发生证实了在隐蔽定向过程中多个独立注意机制的同时运作。
Detection reaction time (RT) at an extrafoveal location can be increased bu noninformative precues presented at that location or ipsilaterally to it. This cue-induced inhibition is called inhibition of return or ipsilateral inhibition. We measured detection RT to simple Light targets at extrafoveal locations that could be designated for covert orienting by local or distant cues. We found that cue-induced inhibition co-occurred in an additive fashion with the direct effects of covert orienting, i.e., it detracted from facilitation at attended locations and increased the disadvantage for unattended locations. Thus, cue-induced inhibition cannot be suppressed by a volitional covert orienting to the cued location; the co-occurrence of different facilitatory and inhibitory effects confirms the simultaneous operation of multiple independent attentional mechanisms during covert orienting.
