The Choreography of Group Affiliation

Published in: Topics in Cognitive Science, Volume 10, Issue 1, 80-94 Abstract “When two people move in synchrony, they become more social. Yet it is not clear how this effect scales up to larger numbers of people. Does a group need to move in unison to affiliate, in what we term unitary synchrony; or does affiliation arise from distributed coordination, patterns of coupled movements between individual members of a group? We developed choreographic tasks that manipulated movement synchrony without explicitly instructing groups to move in unison. Wrist accelerometers measured group movement dynamics and we applied cross‐recurrence analysis to distinguish the temporal features of emergent unitary synchrony (simultaneous… Read More

Multi‐Scale Contingencies During Individual and Joint Action

Published in: Topics in Cognitive Science, Volume 10, Issue 1, 36-54 Abstract “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… Read More

Editor’s Introduction and Review: Coordination and Context in Cognitive Science

Published in: Topics in Cognitive Science, Volume 10, Issue 1, 6-17 Abstract “The role of coordination in cognitive science has been on the rise in recent years, in terms of coordination among neurons, coordination among sensory and motor systems, and coordination among individuals. Research has shown that coordination patterns corresponding to cognitive activities depend on the various contexts in which the underlying interactions are situated. The present issue of Topics in Cognitive Sciencecenters on studies of coordination that address the role of context in shaping or interpreting dynamical patterns of human behavior. This introductory article reviews some of the prior literature leading… Read More

From Adult Finger Tapping to Fetal Heart Beating: Retracing the Role of Coordination in Constituting Agency

Published in: Topics in Cognitive Science, Volume 10, Issue 1, 18-35 Abstract “Sense of agency can be defined as the self‐awareness of bodily movement, whereas extended agency as the self‐awareness of affecting, through movement, events concomitant with movement. As a distinctive manifestation of agency, we review Spizzo’s effect. This effect arises when agents coordinate their rhythmic movements with visual pulses. Once coordination is established, agents feel controlling the onset or the offset of the pulses through their movements. Spizzo’s effect, therefore, constitutes a manifest case of extended agency, in which agents are aware of controlling, through movement, the pulses temporally concomitant with movement. We propose… Read More

Factorization of Force and Timing in Sensorimotor Performance: Long‐Range Correlation Properties of Two Different Task Goals

Published in: Topics in Cognitive Science, Volume 10, Issue 1, 120-132 Abstract “Long‐range correlations are often manifested in the form of 1/fβ noise in a series of repeated measurements of the same neural or behavioral variable. Recent work has demonstrated that the magnitude and nature of these long‐range correlations reliably capture individual differences and variation in task performance. In sensorimotor timing experiments, task characteristics such as tapping or circle drawing affect these long‐range correlations during the production of isochronous time intervals. Such correlations are highly reproducible across multiple trials for the same task but do not correlate between tasks. In the present… Read More
