通过触觉感知的物体识别涉及两个要素：物体的形状（宏观几何属性）和物体的材料（微观几何属性）。在这里，我们试图确定通过触觉感知进行物体识别的微观几何触觉表征的特征。参与者被要求使用触觉信息或视觉信息来识别具有不同表面材料的物体。通过对有关对象识别的认知过程的定量分析，实验 1 证实了在完成任务的触觉和视觉感知中通常生成的相同的八个概念（由定义不同认知过程的规则组成），尽管在视觉任务期间生成了一个附加概念。实验 2 仅关注触觉感知。物体识别任务使用了三种具有不同表面材料（塑料、布料和砂纸）的触觉物体。参与者回答了一份关于得出答案的过程的问卷（该问卷是根据实验 1 中获得的结果设计的），并对生动性、熟悉度和情感效价进行评分。我们利用这些实验数据来研究材料属性（触觉信息）的变化是否会改变触觉表征的特征。观察表明，触觉信息的差异导致认知过程、生动性、熟悉度和情感性的差异。这两个实验共同表明，微观几何触觉信息通过招募包括情景记忆和情感在内的各种认知过程有助于物体识别，类似于通过视觉信息识别物体的情况。
Object recognition through tactile perception involves two elements: the shape of the object (macrogeometric properties) and the material of the object (microgeometric properties). Here we sought to determine the characteristics of microgeometric tactile representations regarding object recognition through tactile perception. Participants were directed to recognize objects with different surface materials using either tactile information or visual information. With a quantitative analysis of the cognitive process regarding object recognition, Experiment 1 confirmed the same eight concepts (composed of rules defining distinct cognitive processes) commonly generated in both tactile and visual perceptions to accomplish the task, although an additional concept was generated during the visual task. Experiment 2 focused only on tactile perception. Three tactile objects with different surface materials (plastic, cloth and sandpaper) were used for the object recognition task. The participants answered a questionnaire regarding the process leading to their answers (which was designed based on the results obtained in Experiment 1) and to provide ratings on the vividness, familiarity and affective valence. We used these experimental data to investigate whether changes in material attributes (tactile information) change the characteristics of tactile representation. The observation showed that differences in tactile information resulted in differences in cognitive processes, vividness, familiarity and emotionality. These two experiments collectively indicated that microgeometric tactile information contributes to object recognition by recruiting various cognitive processes including episodic memory and emotion, similar to the case of object recognition by visual information.
