Social Connection Through Joint Action and Interpersonal Coordination

The pull to coordinate with other individuals is fundamental, serving as the basis for our social connectedness to others. Discussed is a dynamical and ecological perspective to joint action, an approach that embeds the individuals mind in a body and the body in a niche, a physical and social environment. Research on uninstructed coordination of simple incidental rhythmic movement, along with research on goal-directed, embodied cooperation, is reviewed. Finally, recent research is discussed that extends the coordination and cooperation studies, examining how synchronizing with another, and how emergent social units of perceiving and acting are reflected in peoples feelings of connection to others.

Effects of Visual and Verbal Interaction on Unintentional Interpersonal Coordination.

Previous research has demonstrated that peoples movements can become unintentionally coordinated during interpersonal interaction. The current study sought to uncover the degree to which visual and verbal (conversation) interaction constrains and organizes the rhythmic limb movements of coactors. Two experiments were conducted in which pairs of participants completed an interpersonal puzzle task while swinging handheld pendulums with instructions that minimized intentional coordination but facilitated either visual or verbal interaction. Cross-spectral analysis revealed a higher degree of coordination for conditions in which the pairs were visually coupled. In contrast, verbal interaction alone was not found to provide a sufficient medium for unintentional coordination to occur, nor did it enhance the unintentional coordination that emerged during visual interaction. The results raise questions concerning differences between visual and verbal informational linkages during interaction and how these differences may affect interpersonal movement production and its coordination.

Contrasting Approaches to Perceiving and Acting With Others

How and why the presence of a person directly affects the perception and action of another person is a phenomenon that has been approached in a limited and piecemeal fashion within psychology. This kind of diffuse strategy has failed to capture the jointness of perception and action within and between people. In contradistinction, the authors offer a perspective that retains both integrally social features (e.g., involves interaction) and yet adequately exploits the current state of knowledge regarding the ecological properties of perception–action, while at the same time drawing on aspects of dynamic systems theory. In this article the authors review the best attempts to examine how one individual affects anothers perceptions and actions in the emergence of a social unit of action. Two important approaches, the individual-level and cognitive dynamics approaches, have yielded insights that derive in significant degree from principles of ecological psychology and/or dynamical systems theory. Prototypic of the individual-level approach is a focus on what can be perceived by coactors with the aim of uncovering how the dispositional qualities (affordances) of another person are informationally specified during social interaction. In contrast, the cognitive dynamics approach simulates dynamical characteristics of cognition and psychological influence with the aim of uncovering how cooperative interaction emerges out of its component parts. The authors argue that these approaches involve, respectively, insufficient mutuality and insufficient embodiment. Consequently, a social synergy perspective is discussed that approaches the problem of socially cooperative interaction at the relational, nonreductive level, using novel methods to examine how social perception and action emerge through self-organizing processes. The coupling of Gibsons ideas with those of Bernstein forms a natural basis for looking at the traditional psychological topics of perceiving, acting, and knowing as activities of ecosystems rather than isolated animals.

Gaining Control through Counterfactual Thinking

The control-gaining influence of counterfactual thought was examined in a month-long study of real-life exam performances. Participants were contacted immediately after receiving a test grade, the day before their next test, and right after receiving their second grade. Previous research has proposed that upward counterfactuals lead to improved future performance. The present study aimed to identify mediators of this process. Participants who generated more upward counterfactuals were predicted to perceive enhanced control over the environment and to engage in more action on their environment. Subsequent test performance should thus improve. Results showed that the tendency to generate upward counterfactuals was correlated with later changes in circumstances, which in turn, was associated with higher perceptions of control; control perceptions were correlated with better subsequent grades. Implications of results for social cognition, action, and control processes are discussed.

Heart versus reason in condom use: implicit versus explicit attitudinal predictors of sexual behavior.

We test the hypothesis that explicit and implicit measures of attitudes would differentially predict deliberate versus spontaneous behavior in the domain of condom use. Students completed explicit attitudinal and thought-listing measures about using condoms and implicit measures using attitude priming and Implicit Association Test (IAT) procedures. An attitude IAT measured the association between condom images and affective images; a self-identity IAT measured association of condoms with the self. We predicted and found that condom use with main partners was predicted by explicit measures but not implicit measures; the opposite was true for condom use with casual partners. Although the attitude priming measure was not positively correlated with casual condom use, the IATs were. The patterns of relations, however, were unexpectedly complex, due to a strong decrease in IAT effects over time, and different IATs assessing unique attitudinal dimensions.

Rocking to the beat: effects of music and partner's movements on spontaneous interpersonal coordination.

People move to music and coordinate their movements with others spontaneously. Does music enhance spontaneous coordination? We compared the influence of visual information (seeing or not seeing another person) and auditory information (hearing movement or music or hearing no sound) on spontaneous coordination. Pairs of participants were seated side by side in rocking chairs, told a cover story, and asked to rock at a comfortable rate. Both seeing and hearing the other person rock elicited spontaneous coordination, and effects of hearing amplified those of seeing. Coupling with the music was weaker than with the partner, and the music competed with the partners influence, reducing coordination. Music did, however, function as a kind of social glue: participants who synchronized more with the music felt more connected.

Language Use, Coordination, and the Emergence of Cooperative Action

Over the last three decades, two major theoretical developments within cognitive science have enriched our understanding of perceptual function and coordinated action in real-world environments.

Autism and social disconnection in interpersonal rocking.

Individuals with autism spectrum disorders (ASDs) have significant visuomotor processing deficits, atypical motoric behavior, and often substantial problems connecting socially. We suggest that the perceptual, attentional, and adaptive timing deficiencies associated with autism might directly impact the ability to become a socially connected unit with others. Using a rocking chair paradigm previously employed with typical adults, we demonstrate that typically-developing (TD) children exhibit spontaneous social rocking with their caregivers. In contrast, children diagnosed with ASD do not demonstrate a tendency to rock in a symmetrical state with their parents. We argue that the movement of our bodies is one of the fundamental ways by which we connect with our environment and, especially, ground ourselves in social environments. Deficiencies in perceiving and responding to the rhythms of the world may have serious consequences for the ability to become adequately embedded in a social context.

Affording cooperation: Embodied constraints, dynamics, and action-scaled invariance in joint lifting

Understanding the physical and interpersonal constraints that afford cooperation during real-world tasks requires consideration of the fit between the environment and task-relevant dimensions of coactors and the coactors’ fit with each other. In the present study, we examined how cooperation can emerge during ongoing interaction using the simple task of two actors’ moving long wooden planks. The system dynamics showed hysteresis: A past-action mode persisted when both solo and joint actions were possible. Moreover, pairs whose arm spans were both short, both long, or mismatched made action-mode transitions at similar points, when scaled by a relational measure. The relational measure of plank length to arm span was dictated by the pair member with the shorter arm span, who, thus, had a greater need to cooperate during the task. The results suggest that understanding affordances for cooperation requires giving more consideration to constraints imposed by the fit between coactors’ action capabilities.

Condoms + pleasure=safer sex? A missing addend in the safer sex message

Abstract Since the emergence of HIV, sexual risk-reduction intervention and prevention programmes have promoted the ‘condoms equal safer sex’ message with a particular focus on the preventative aspects of condoms (i.e. disease or pregnancy prevention). Yet despite the pervasiveness of this message, research has found that most people fail to use condoms consistently. Using the thought-listing technique, we asked men who have sex with men (MSM) and heterosexuals to list thoughts that immediately came to mind when thinking about condoms. Results show that MSM have more sexual/sensory associations to condoms than heterosexuals, suggesting that interventions highlighting the sexual/sensory aspects of condoms might be an important component to increase condom use among MSM while a combined approach (i.e. messages that integrate preventative, interpersonal, and sexual/sensory components) might be more appealing to heterosexuals.
