对57名正常裸眼大学生进行了3项研究，考察了时间不连续对视觉搜索的影响。向SS展示了一个显示，其中1个项目出现突然发作，而其他项目通过逐渐移除伪装它们的线段来引入。有人假设，视觉显示的突然出现将吸引视觉注意力，使这一项目相对于没有突然前沿的项目具有处理优势。这一假设在实验一中得到了证实。实验二是为了区分实验一中观察到的效应的知觉解释和注意解释。结果表明，当注意在视觉显示之前被适当地引导时，突然开始比逐渐不开始没有优势。实验I基于注意捕获的解释得到了支持。Exp III复制了Exp I，并证明了用于避免突然发作(即，去除伪装)的程序不需要渐进的波形。讨论了这些发现对注意力理论的影响。(参考文献51)(心理信息数据库记录(C)2016 APA，版权所有)
Examined the effect of temporal discontinuity on visual search in 3 studies with 57 college students with normal uncorrected vision. Ss were presented with a display in which 1 item had an abrupt onset, while other items were introduced by gradually removing line segments that camouflaged them. It was hypothesized that an abrupt onset in a visual display would capture visual attention, giving this item a processing advantage over items lacking an abrupt leading edge. This hypothesis was confirmed in Exp I. Exp II was conducted to distinguish between a perceptual and an attentional explanation for the effects observed in Exp I. Results indicate that when attention was appropriately directed in advance of a visual display, there was no advantage for abrupt onsets over gradual no-onsets. An explanation of Exp I based on attentional capture is supported. Exp III replicated Exp I and demonstrated that the procedure used to avoid abrupt onset (ie, camouflage removal) did not require a gradual waveform. Implications of these findings for theories of attention are discussed.(51 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
