Subjects identified common objects under conditions of a "haptic glance," a brief haptic exposure that placed severe spatial and temporal constraints on stimulus processing. They received no advance cue, a superordinate-level name as cue, or a superordinate and basic-level name as cue. The objects varied in size relative to the fingertip and in the most diagnostic attribute, either texture or shape. The data suggest that object recognition can occur when global volumetric primitives cannot directly be extracted. Even with no cue, confusion errors resembled the target object and indicated extraction of material and local shape information, which was sufficient to provide accuracy above 20%. Performance improved with cuing, and the effect of exposure duration was observed primarily with minimal cuing, indicating compensatory effects of top-down processing.
受试者在“触觉扫视”条件下识别常见物体，“触觉扫视”是一种短暂的触觉暴露，对刺激处理施加了严格的空间和时间限制。他们没有收到预先提示、作为提示的上位类别名称或作为提示的上位和基本类别名称。这些物体在相对于指尖的大小以及最具诊断性的属性（纹理或形状）方面各不相同。数据表明，当无法直接提取全局体积原语时，物体识别仍可发生。即使没有提示，混淆错误也与目标物体相似，表明提取了材料和局部形状信息，这足以提供高于20%的准确率。提示可提高表现，暴露持续时间的影响主要在最小提示条件下观察到，表明自上而下加工的补偿作用。
