Multi-Scale Contingencies During Individual and Joint Action.
The present paper describes a joint action paradigm in which individuals or pairs utilized two computer keys to keep a dot stimulus moving inside a larger rectangle. Members of a pair could neither see nor hear each other. This paradigm allowed us to combine the discrete-trial type dependent variables (e.g., reaction time) commonly utilized by representational theorists, with the continuous, temporal dependence variables (e.g., RQA) utilized by dynamical theorists. Analysis revealed that individuals kept the dot in the rectangle longer than dyads and did so by moving it back and forth within the rectangle. Dyads, however, pressed their individual buttons as quickly as possible in order to keep the dot near the middle of the rectangle. These findings indicate that joint action constitutes a multi-scale phenomena that is best investigated via multiple, complementary methodologies versus single-measure, competing theories.
