ABSTRACT
The field of joint action research has rapidly emerged from the realization that studying the mind exclusively in insular contexts may be insufficient for fully understanding how cognition works (Sebanz, Bekkering, & Knoblich, 2006). To go further, one may argue that several cognitive functions are shaped, and in some cases only exist, to engage in joint contexts. Language provides a clear example in this regard, as one could imagine the hypothetical scenario of a world in which individuals would not engage in any social interaction. In such a scenario, the functionality of knowing a language would be rather minimal, and language may not have existed under such a pretense in the first place.
