Information about the timing of spontaneous eye blinks was abstracted while subjects performed a detection and identification task. We found blinks to be time-locked to saccadic eye movements involved in the identification of peripherally presented stimuli. The larger the required eye movement, the greater the likelihood of blink occurrence. Blink latencies were found to be significantly shorter for centrally, as compared to peripherally presented stimuli, and blinks were more likely to be associated with eye movement returning gaze to a central location than with movements associated with the identification of peripherally presented information. Thus, we conclude that the spontaneous or endogenous eye blink is triggered by aspects of information processing, and that blink latencies can be used as one tool for evaluating the level of complexity of such processing under a wide variety of task demands.
在受试者执行检测和识别任务时，提取了有关自发性眨眼时间的信息。我们发现眨眼与识别周边呈现刺激时的眼球跳动在时间上是同步的。所需的眼球运动幅度越大，眨眼发生的可能性就越大。与周边呈现的刺激相比，发现中央呈现刺激时的眨眼潜伏期明显更短，并且眨眼更有可能与将注视返回中央位置的眼球运动相关，而不是与识别周边呈现信息相关的运动。因此，我们得出结论，自发性或内源性眨眼是由信息处理的各个方面触发的，并且眨眼潜伏期可以用作在各种任务需求下评估此类处理复杂性水平的一种工具。
