Reciprocity and alignment: quantifying coupling in dynamic interactions

Recent accounts of social cognition focus on how we do things together, suggesting that becoming aligned relies a reciprocal exchange information. The next step is to develop richer computational methods quantify the degree coupling and describe nature information exchange. We put forward definition coupling, comparing it related terminology detail, available level organization which they pertain, presenting them as hierarchy from weakest richest forms coupling. rationale temporally coherent link between two dynamical systems at lowest sustains mutual adaptation alignment highest level. Postulating when so dynamically over time argue determine measure instances true reciprocity in exchanges key. Along with this computationally rich present challenges for field be tackled by diverse community working towards dynamic account cognition.
