Orienting attention exogenously to a location can have two different consequences on processing subsequent stimuli appearing at that location: positive (facilitation) at short intervals and negative (inhibition of return) at long ones. In the present experiments, we manipulated the frequency of targets and responses associated with them. Results showed that, even at long SOAs, where IOR is usually observed, facilitation was observed for infrequent targets at the same time that IOR was measured for frequent targets. These results are difficult to explain on the basis of either task set modulation of attentional capture or task set modulation of subsequent orienting processes. In contrast, we offer an explanation by which the different cuing effects can be considered as different manifestations of attentional capture on target processing, depending on the task set.
将注意力外源性地定向到一个位置，可能会对随后出现在该位置的刺激处理产生两种不同的结果：短间隔时为正向（促进），长间隔时为负向（返回抑制）。在本实验中，我们操纵了目标及其相关反应的频率。结果表明，即使在通常观察到返回抑制的长刺激间隔条件下，在测量频繁目标的返回抑制的同时，也观察到了对不频繁目标的促进作用。基于注意力捕获的任务集调制或后续定向过程的任务集调制，这些结果都很难解释。相比之下，我们提出了一种解释，根据任务集，不同的线索效应可被视为注意力捕获对目标处理的不同表现形式。
