In the present study, we used a spatial cuing paradigm in conjunction with a choice identification task to investigate whether exogenous attentional orienting and inhibition of return are affected by attentional control settings. As in previous studies (e.g., Folk, Remington, & Johnston, 1992), onset- and color-defined targets were crossed with uninformative onset- and color-defined cues. As expected, when the cue-target stimulus onset asynchrony (SOA) was short (i.e., 100 msec), the results showed that exogenous attentional orienting was contingent on attentional set; attentional capture occurred in response to a particular cue only when the feature that defined the cue also defined the target (Folk et al., 1992). More importantly, when the cue-target SOA was long (i.e., 1,000 msec), the results showed that the occurrence of inhibition of return was also contingent on attentional set, at least partially so; inhibition of return occurred in response to onset cues only when they preceded onset targets. In contrast, inhibition of return never occurred in response to color cues (at a variety of long SOAs). The associations and dissociations that were observed between exogenous attentional orienting and inhibition of return are discussed in terms of posterior and anterior attention networks in the brain (Posner & Petersen, 1990).
在本研究中，我们使用空间线索范式结合选择识别任务，来探究外源性注意定向和返回抑制是否受注意控制设置的影响。与之前的研究（如Folk、Remington和Johnston，1992）一样，起始点和颜色定义的目标与无信息的起始点和颜色定义的线索交叉呈现。正如预期的那样，当线索 - 目标刺激起始异步性（SOA）较短（即100毫秒）时，结果表明外源性注意定向取决于注意集；只有当定义线索的特征也定义目标时，注意才会被特定线索捕获（Folk等人，1992）。更重要的是，当线索 - 目标SOA较长（即1000毫秒）时，结果表明返回抑制的出现也取决于注意集，至少部分如此；只有当起始线索先于起始目标出现时，才会出现对起始线索的返回抑制。相比之下，（在各种较长的SOA条件下）对颜色线索从未出现返回抑制。根据大脑中的后部和前部注意网络（Posner和Petersen，1990），对外源性注意定向和返回抑制之间观察到的关联和分离进行了讨论。
