Interpersonal synergies.

Riley MA, Richardson MJ, Shockley K, Ramenzoni VC - Front Psychol (2011)

Bottom Line: Interpersonal synergies are higher-order control systems formed by coupling movement system degrees of freedom of two (or more) actors.Characteristic features of synergies identified in studies of intrapersonal coordination - dimensional compression and reciprocal compensation - are revealed in studies of interpersonal coordination that applied the uncontrolled manifold approach and principal component analysis to interpersonal movement tasks.Broader implications of the interpersonal synergy approach for movement science include an expanded notion of mechanism and an emphasis on interaction-dominant dynamics.

ABSTRACT
We present the perspective that interpersonal movement coordination results from establishing interpersonal synergies. Interpersonal synergies are higher-order control systems formed by coupling movement system degrees of freedom of two (or more) actors. Characteristic features of synergies identified in studies of intrapersonal coordination - dimensional compression and reciprocal compensation - are revealed in studies of interpersonal coordination that applied the uncontrolled manifold approach and principal component analysis to interpersonal movement tasks. Broader implications of the interpersonal synergy approach for movement science include an expanded notion of mechanism and an emphasis on interaction-dominant dynamics.

(A) Depiction of the individual- (left) and interpersonal- (right) task conditions from Ramenzoni (2008). (B) Time series of the data projected onto the intrapersonal principle components from the individual (left) and interpersonal-task (right) conditions. The striking coordination in the interpersonal-task condition was confirmed by cross-recurrence quantification analysis, which revealed a greater degree and higher stability of coupling in that condition.

Figure 3: (A) Depiction of the individual- (left) and interpersonal- (right) task conditions from Ramenzoni (2008). (B) Time series of the data projected onto the intrapersonal principle components from the individual (left) and interpersonal-task (right) conditions. The striking coordination in the interpersonal-task condition was confirmed by cross-recurrence quantification analysis, which revealed a greater degree and higher stability of coupling in that condition.

Mentions: The first study we discuss (Ramenzoni, 2008) involved pairs of participants performing an interpersonal precision task. One participant held a target (a circle), while another held a pointer through the circle without touching its sides (Figure 3A). Smaller circles were used to create more difficult task conditions. Preliminary results showed that with greater task difficulty participants’ hand and torso movements became increasingly coordinated (as quantified by cross-recurrence quantification analysis – CRQA; Webber and Zbilut, 1994; Shockley et al., 2002; Shockley, 2005; Richardson et al., 2007). CRQA quantifies the degree of shared activity between two time series by evaluating how they unfold similarly over time in a multi-dimensional (embedding) space. The proportion of body configurations shared between the time series (an overall measure of coordination) and how long they maintain similar patterns (how stable the coordination is) are among the CRQA measures (see Webber and Zbilut, 1994).
