通过两个实验考察了背景连贯场景中整体信息加工对物体识别的影响。在实验1中，受试者观看100ms的线条画演示，其中包含在图片背景下常见或不寻常的物体。每次曝光后，他们被要求从4个物体中选择场景中包含的1个物体。三个分心选项与图片含义的一致性是不同的。对于不寻常的物体，当干扰与图片的含义一致，并且与被试在没有实际观看图片的情况下，在获得图片主题后选择反应备选方案的表现没有实质性差异时，识别准确率较差。受试者显然是基于图片中的全局信息而不是局部物体信息做出反应。当暴露时间增加到2个S(实验2)时，对普通和不寻常物体的局部信息加工都是明显的，但全局信息的影响仍然明显。
The effect on object recognition of the processing of the global information in contextually coherent scenes was investigated in 2 experiments. In experiment 1, human subjects saw 100 ms presentations of line drawings containing objects that were either usual or unusual given the picture context. Following each exposure they were required to select from among 4 objects the 1 that had been contained in the scene. The consistency of the 3 distractor alternatives with the meaning of the picture was varied. Recognition accuracy was poor for unusual objects and when the distractors were consistent with the picture meaning and did not substantially differ from the performance of subjects who selected response alternatives after being provided with a theme of the picture, without actually viewing the pictures. Subjects were apparently responding on the basis of the global information but not the local object information in the pictures. When the exposure duration was increased to 2 s (experiment 2), processing of local information was apparent for both usual and unusual objects but effects of the global information were still evident.
