The aim of the present study was to investigate the effects of communicative intention on action. In Experiment 1 participants were requested to reach towards an object, grasp it, and either simply lift it (individual condition) or lift it with the intent to communicate a meaning to a partner (communicative condition). Movement kinematics were recorded using a three-dimensional motion analysis system. The results indicate that kinematics was sensitive to communicative intention. Although the to-be-grasped object remained the same, movements performed for the 'communicative' condition were characterized by a kinematic pattern which differed from those obtained for the 'individual' condition. These findings were confirmed in a subsequent experiment in which the communicative condition was compared to a control condition, in which the communicative exchange was prevented. Results are discussed in terms of cognitive pragmatics and current knowledge on how social behavior shapes action kinematics.
本研究的目的是调查交际意图对动作的影响。在实验1中，要求参与者伸手去拿一个物体，抓住它，然后要么简单地举起它（个体条件），要么带着向伙伴传达某种意义的意图举起它（交际条件）。使用三维运动分析系统记录运动学数据。结果表明，运动学对交际意图很敏感。尽管要抓的物体保持不变，但在“交际”条件下执行的动作具有一种运动学模式，该模式与在“个体”条件下获得的模式不同。在随后的一项实验中，将交际条件与一个阻止交际交流的控制条件进行了比较，这些发现得到了证实。将根据认知语用学以及关于社会行为如何塑造动作运动学的现有知识来讨论结果。
