正如Yantis和Jonides（1984）所提出的那样，突然的视觉开始自动捕获注意力的假设在四个实验中得到了验证。一种位于中心的线索，将注意力引导到几个刺激位置之一，为识别嵌入在一系列干扰字母中的目标字母做准备。在所有的实验中，一个刺激（目标或干扰物之一）有一个突然的开始，其余的字母没有。操纵的有效性的线索（改变其持续时间或其预测有效性），以测试是否突然发作捕捉注意力，即使受试者是在一个高度集中的注意力状态。结果表明，发作并不一定捕获注意违反观察者的意图。本文提出了一种由突然启动引起的部分自动注意捕获机制，并讨论了自动性的意向性判据的诊断性。
The hypothesis that abrupt visual onsets capture attention automatically, as suggested by Yantis and Jonides (1984) was tested in four experiments. A centrally located cue directed attention to one of several stimulus positions in preparation for the identification of a target letter embedded in an array of distractor letters. In all experiments, one stimulus (either the target or one of the distractors) had an abrupt onset; the remaining letters did not. The effectiveness of the cue was manipulated (varying either its duration or its predictive validity) to test whether abrupt onsets capture attention even when subjects are in a highly focused attentional state. Results showed that onsets do not necessarily capture attention in violation of an observer’s intentions. A mechanism for partially automatic attentional capture by abrupt onset is proposed, and the diagnosticity of the intentionality criterion for automaticity is discussed.
