Merely observing how another person responds to a stimulus results in incidental stimulus-response (SR) bindings in memory. These observationally acquired SR bindings can be retrieved on a later occasion. Retrieval will bias current behavioral response tendencies towards re-execution of the observed response. Previous demonstrations of this effect endorsed a dyadic interaction paradigm in which two co-actors respond in alternating fashion. The present paper investigates a video-based version of the observational SR binding task in which videotaped responses are observed on screen. Whereas findings from the dyadic paradigm indicate that retrieval of observationally acquired SR bindings is modulated by social relevance, the video-based paradigm is not influenced by social moderators. Data of four experiments show that manipulations of visual perspective, natural and artificial group membership had no modulatory effect on retrieval of observationally acquired SR bindings in the video-based paradigm. The absence of any socially modulated effect in the video-based paradigm is supported by Bayesian statistics in favor of the null hypothesis. Data from a fifth experiment suggests that observational SR binding and retrieval effects in the video-based paradigm reflect the influence of spatial attention allocated towards response keys of observed responses. Implications for the suitability of both paradigms to study observational learning and joint action phenomena are discussed.

仅仅观察另一个人对刺激的反应会导致记忆中偶然的刺激-反应（SR）结合。这些观察获得的SR绑定可以在以后的情况下检索。检索将使当前的行为响应趋势偏向于重新执行所观察到的响应。先前对此效果的演示证实了二元交互作用范式，其中两个共同角色以交替方式响应。本文研究了观察性SR绑定任务的基于视频的版本，其中在屏幕上观察到录像带的响应。尽管来自二进式范式的发现表明，观察获得的SR绑定的检索受社交相关性的调节，而基于视频的范式不受社交主持人的影响。四个实验的数据表明，在基于视频的范例中，对视觉角度，自然和人工组成员的操纵对观察到的SR绑定的检索没有调制作用。贝叶斯统计支持基于视频的范式中不存在任何社会调节效应，这支持零假设。来自第五个实验的数据表明，基于视频的范例中的观察性SR绑定和检索效果反映了空间注意力分配给观察到的响应的响应键的影响。讨论了两种范式是否适合研究观察性学习和关节动作现象的含义。贝叶斯统计支持基于视频的范式中不存在任何社会调节效应，这支持零假设。来自第五个实验的数据表明，基于视频的范例中的观察性SR绑定和检索效果反映了空间注意力分配给观察到的响应的响应键的影响。讨论了两种范式是否适合研究观察性学习和关节动作现象的含义。贝叶斯统计支持基于视频的范式中不存在任何社会调节效应，这支持零假设。来自第五个实验的数据表明，基于视频的范例中的观察性SR绑定和检索效果反映了空间注意力分配给观察到的响应的响应键的影响。讨论了两种范式是否适合研究观察性学习和关节动作现象的含义。
