通过比较共享一个共同的传出通路，但有不同的传入肢体的脑干反射的影响，自动的，感觉过程是否可以通过选择性地将注意力引导到刺激来修改的问题。受试者判断的持续时间短暂，但强烈的眨眼引发的音调（实验1）或微弱的音调之前眨眼引发的空气喷在刺激间隔产生眨眼抑制（实验2）。音调在左、右或中线位点不可预测地发生;靶位置的指定在试验区组中各不相同。选择性地促进了侧化眨眼诱发目标的眨眼潜伏期，选择性地抑制了侧化前刺激目标后由空气抽吸诱发的眨眼幅度。没有证据表明存在中线选择性效应。结果似乎支持预设的差异处理的刺激在感觉通路在低，可能是皮层下，水平和随之而来的修改的强制性，自动的过程。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
The question of whether automatic, sensory processes can be modified by selectively directing attention to stimuli was addressed by comparing effects on brainstem reflexes that share a common efferent pathway but have distinct afferent limbs. Subjects judged the duration of brief but intense blink-eliciting tones (Experiment 1) or weak tones preceding a blink-eliciting air puff at interstimulus intervals producing blink inhibition (Experiment 2). Tones occurred unpredictably at left, right, or midline loci; designation of the target location varied across blocks of trials. Latency of blinks to lateralized blink-eliciting targets was facilitated selectively, and the magnitude of blinks evoked by air puff following lateralized prestimulus targets was inhibited selectively. There was no evidence for a midline selective effect. Results appear to support a preset differential processing of stimuli in sensory pathways at low, possibly subcortical, levels and the consequent modification of obligatory, automatic processes.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
