Recent studies show that spatial attention is uniquely engaged by the selection history of a stimulus. One example of this process is Automated Symbolic Orienting, which is thought to reflect overlearned spatial links between a behaviorally relevant stimulus and a target event. However, since automated symbolic effects have been found to vary with temporal expectancies about when a target might occur, it is possible that this spatial effect may also depend on processing resources associated with voluntary temporal attention. To test this idea, here we elicited automated symbolic orienting and voluntary temporal attention in isolation and in combination. Across all conditions, both types of orienting remained typical without interacting. Thus, typical automated symbolic orienting is not modulated by participants' explicit utilization of temporal information; however, and as we have shown previously, typical ASO does appear to require the presence of an implicit temporal structure within a task.
最近的研究表明，空间注意力是由刺激的选择历史独特地引发的。这一过程的一个例子是自动符号定向，它被认为反映了行为相关刺激与目标事件之间过度学习的空间联系。然而，由于已发现自动符号效应会随对目标何时可能出现的时间预期而变化，所以这种空间效应也可能取决于与自愿时间注意力相关的处理资源。为了验证这一想法，我们在这里分别以及同时引发了自动符号定向和自愿时间注意力。在所有条件下，两种定向类型都保持典型且互不影响。因此，典型的自动符号定向不会因参与者对时间信息的明确利用而受到调节；然而，正如我们之前所表明的，典型的自动符号定向似乎确实需要任务中存在隐含的时间结构。
