Abstract

Interpersonal action coordination relies on an information channel between co-actors. Previous studies have shown that offline or online visual, auditory, and haptic information can facilitate joint action. However, most previous studies only investigated the information that is naturally meaningful in the task context. Few explanations have been given about the underlying mechanism of this facilitation effect. The current study was designed to investigate what makes the information useful in improving joint action performance. I argued that externally added information (action effects) can also facilitate joint action. According to the Theory of Event Coding (TEC), once the association between an action and its effects are built, action control can be achieved by effects control. Thus, by adding external action effects in joint action, co-actors are able to perceive the action and intention of each other and coordinate their action accordingly. In the current study, the utility of a color action effect in a joint movement control task was tested. An association test was used to examine the hypothesis of TEC. The results, for the first time, revealed that action effects are coded in dynamical, flexible forms in action concept.
