We investigated whether and how comprehending sentences that describe a social context influences our motor behaviour. Our stimuli were sentences that referred to objects having different connotations (e.g., attractive/ugly vs. smooth/prickly) and that could be directed towards the self or towards "another person" target (e.g., "The object is ugly/smooth. Bring it to you/Give it to another person"). Participants judged whether each sentence was sensible or non-sensible by moving the mouse towards or away from their body. Mouse movements were analysed according to behavioral and kinematics parameters. In order to enhance the social meaning of the linguistic stimuli, participants performed the task either individually (Individual condition) or in a social setting, in co-presence with the experimenter. The experimenter could either act as a mere observer (Social condition) or as a confederate, interacting with participants in an off-line modality at the end of task execution (Joint condition). Results indicated that the different roles taken by the experimenter affected motor behaviour and are discussed within an embodied approach to language processing and joint actions.
我们研究了理解描述社会情境的句子是否以及如何影响我们的运动行为。我们的刺激物是那些提及具有不同内涵的物体的句子（例如，有吸引力的/丑陋的与光滑的/多刺的），并且这些句子可以针对自我或“另一个人”目标（例如，“这个物体是丑陋的/光滑的。把它拿给你/把它给另一个人”）。参与者通过将鼠标移向或远离自己的身体来判断每个句子是否合理。根据行为和运动学参数分析鼠标移动情况。为了增强语言刺激的社会意义，参与者要么单独执行任务（个体条件），要么在与实验者共同在场的社会环境中执行任务。实验者要么仅仅作为观察者（社会条件），要么作为同盟者，在任务执行结束时以离线方式与参与者互动（联合条件）。结果表明，实验者所扮演的不同角色会影响运动行为，并在语言处理和联合行动的具身方法中进行了讨论。
