The orienting of attention has been found to be influenced by the previous cueing status in a spatial-cueing paradigm. The explanation for this sequence effect remains uncertain. This study separated the involuntary and the voluntary components of arrow cueing by manipulating the predicted target locations. For example, a left arrow cue may have indicated that the target was more likely to appear at the up location. Therefore, three trial types were repeated or switched between trials: cued (targets appeared along the direction of the arrows), predicted (targets appeared at the locations predicted by the arrows), and unrelated (targets appeared at the other two locations, neither cued nor predicted). RTs of cued trials were found to be significantly facilitated after a previous cued trial; however, the same effect was not observed for predicted trials. The results suggest that significant sequence effects are induced only in the involuntary component of arrow cueing. The findings support the feature-integration hypothesis for the sequence effect of symbolic cueing.
在空间线索范式中，人们发现注意力的定向会受到先前线索状态的影响。这种序列效应的解释仍不确定。本研究通过操纵预测的目标位置，将箭头线索的非自愿和自愿成分区分开来。例如，向左的箭头线索可能表明目标更有可能出现在上方位置。因此，三种试验类型在试验之间重复或切换：线索提示（目标沿箭头方向出现）、预测（目标出现在箭头预测的位置）和无关（目标出现在其他两个位置，既不是线索提示的也不是预测的）。发现在先前的线索提示试验之后，线索提示试验的反应时显著加快；然而，预测试验并未观察到同样的效果。结果表明，显著的序列效应仅在箭头线索的非自愿成分中诱发。这些发现支持了符号线索序列效应的特征整合假说。
