An increasing number of studies are investigating the cognitive processes underlying human-object interactions. For instance, several researchers have manipulated the type of grip associated with objects in order to study the role of the objects' motor affordances in cognition. The objective of the present study was to develop norms for the types of grip employed when grasping and using objects, with a set of 296 photographs of objects. On the basis of these ratings, we computed measures of agreement to evaluate the extent to which participants agreed about the grip used to interact with these objects. We also collected ratings on the dissimilarity between the grips employed for grasping and for using objects, as well as the number of actions that can typically be performed with the objects. Our results showed grip agreements of 67 % for grasping and of 65 % for using objects. Moreover, our pattern of correlations is highly consistent with the idea that the grips for grasping and using objects represent two different motor dimensions of the objects.
越来越多的研究正在探究人类与物体相互作用背后的认知过程。例如，一些研究人员操纵了与物体相关的握持类型，以研究物体的运动启示在认知中的作用。本研究的目的是为抓握和使用物体时所采用的握持类型制定规范，为此我们使用了一组 296 张物体的照片。基于这些评分，我们计算了衡量一致性的指标，以评估参与者在使用这些物体时对所采用的握持方式的一致性程度。我们还收集了关于抓握和使用物体时握持方式之间的差异以及通常可以用物体执行的动作数量的评分。我们的研究结果表明，抓握的一致性为 67%，使用的一致性为 65%。此外，我们的相关模式非常符合这样一种观点，即抓握和使用物体的握持方式代表了物体的两个不同的运动维度。
