虽然注意瞬脱和前脉冲惊吓抑制之间的联系已经被认为是，没有证据表明这种关系已被报道。我们在快速连续视觉演示期间提供了声学惊吓探针，其中两个目标（目标1和2）的相对位置在干扰物流中变化。惊吓探针以相对于目标或干扰物的发作的100 ms导联间隔呈现。我们发现视觉前脉冲抑制和注意力瞬脱效应之间存在正相关。随着前脉冲抑制与目标和分心物铅刺激的幅度增加，在识别目标2在注意瞬脱增加赤字，这表明这些现象的基础上类似的过程。而前脉冲抑制可能揭示抑制的强度，以保护刺激处理，注意瞬脱可能指数从类似的抑制过程的恢复率。
Although a link between the attentional blink and prepulse startle inhibition has been considered, no evidence of this relationship has been reported. We delivered acoustic startle probes during rapid serial visual presentations in which the relative positions of two targets (targets 1 and 2) was varied within a stream of distractors. Startle probes were presented at 100 ms lead intervals relative to onset of a target or distractor. We found positive correlations between visual prepulse inhibition and attentional blink effects across participants. As the magnitude of prepulse inhibition with target and distractor lead stimuli increased, deficits in identifying target 2 during the attentional blink increased, suggesting similar processes underlying these phenomena. Whereas prepulse inhibition may reveal the strength of inhibition to protect stimulus processing, attentional blink may index the rate of recovery from similar inhibitory processes.
