作者研究了通过操纵碎片的数量和研究的性质来导致物体识别的视觉处理。在研究过程中，参与者在实验1中命名或画出物体，并在实验2中画出所有物体。在测试过程中，参与者对已研究对象和新对象分别在6个不同的碎片化水平上进行识别判断。鉴定研究过的物体所需的碎片比鉴定未研究过的物体所需的碎片要少。研究对象的反应时间（RTs）在识别和前一个水平上都比未研究对象快。事件相关脑电位（事件相关脑电位）对未识别物体表现出晚期负性，而对已识别物体表现出晚期正性。研究对象的erp，而不是新对象的erp，在识别之前的水平上包含更小和更晚版本的识别阳性，这不是由于差异反应置信度。许多隐蔽的视觉分析甚至物体识别可能先于公开识别，这取决于先前经验的性质。（PsycINFO数据库记录(c) 2016 APA，版权所有）
The authors investigated visual processing leading to object identification by manipulating the number of fragments and nature of the study. During the study, participants either named or drew objects in Experiment 1 and drew them all in Experiment 2. During the test, participants made an identification judgment at each of 6 different fragmentation levels for studied and new objects. Fewer fragments were needed to identify studied than unstudied objects. Reaction times (RTs) were faster for studied than unstudied objects both at identification and at the preceding level. Event-related brain potentials (ERPs) to unidentified objects were characterized by a late negativity in contrast to a positivity to identified objects. ERPs to studied but not to new objects contained a smaller and later version of the identification positivity at level just prior to identification, which was not due to differential response confidence. Much covert visual analysis and even object identification may precede overt identification, depending on the nature of prior experience.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
