在感觉运动控制的直接参数说明(DPS)模式中，反应参数可以由非有意识感知的刺激来指定[心理学研究/心理学Forschung 52(1990)207]。存款保障计划取决于当前的意图。只有当看不见的刺激与实际意图相匹配时，才能对它们进行处理，以用于感觉运动控制，例如，共享与任务相关的特征。本实验探讨了被掩蔽的突发性刺激引起的注意捕获是否通过DPS调节。参与者判断两个视觉目标中哪一个最先出现。蒙面质数在其中一个目标之前。质点要么与目标相似，要么形状相似，要么颜色不同。素数类似于目标(与任务相关)，但不像分心因素(与任务无关)，促进了落后于其位置的目标的知觉潜伏期。因此，潜伏期效应是由注意转移的DPS引起的，而不是来自自下而上的捕获或自上而下的动态特征搜索。
In the direct parameter specification (DPS) mode of sensorimotor control, response parameters can be specified by stimuli that are not consciously perceived [Psychological Research/Psychologische Forschung 52 (1990) 207]. DPS is contingent on the current intentions. The invisible stimuli can be processed for the purposes of sensorimotor control only if they match the actual intentions, for example, share task-relevant features. The present experiments explore whether attentional capture by masked abrupt-onset stimuli is mediated via DPS. Participants judged which of two visual targets appeared first. Masked primes preceded one of the targets. The primes were either similar to the targets or not, in shape, or in color. Target-like (task-relevant), but not distractor-like (task-irrelevant), primes facilitated perceptual latencies of targets trailing at their positions. Thus, the latency effects resulted from DPS of an attention shift, rather than from bottom-up capture or from top-down search for dynamic features.
