Joint Perception of a Shared Object: A Minimalist Perceptual Crossing Experiment.

Deschamps L, Lenay C, Rovira K, Le Bihan G, Aubert D - Front Psychol (2016)

Bottom Line: The main results suggest that the mutual awareness of a shared object (SO) arises from the quality of sensorimotor coordination between the partners.Indeed, the presence of a SO acts as a simultaneous affordance that attracts and structures individual perceptive activities, giving both partners the opportunity to co-construct a shared world where their respective actions make sense.We discuss our results by way of an enactive account of social cognition, taking the joint perception of a SO as a first step to account for joint attention.

ABSTRACT
The minimalist perceptual crossing paradigm has emphasized the essential role of interpersonal dynamics on social understanding. Within the particular case of minimalist interaction, it has been argued that interpersonal processes can constitute social cognition, at least partially, which calls for a paradigm shift in social cognition studies. In this paper, we review several perceptual crossing experiments and their theoretical implications, and propose an original experiment to go beyond strictly dyadic interactions. Whereas past experiments have used objects as distracters of dyadic interaction, our experiment aims at integrating objects themselves as the goal of interpersonal coordination. We asked 24 subjects to participate in a minimalist perceptual crossing experiment where they had to decide, based on their on-line interaction in a one-dimensional digital space, which of the objects they perceived was also perceptible by their partner. The main results suggest that the mutual awareness of a shared object (SO) arises from the quality of sensorimotor coordination between the partners. Indeed, the presence of a SO acts as a simultaneous affordance that attracts and structures individual perceptive activities, giving both partners the opportunity to co-construct a shared world where their respective actions make sense. We discuss our results by way of an enactive account of social cognition, taking the joint perception of a SO as a first step to account for joint attention.

Schematic illustration of the one-dimensional digital space explored by the participants. Participant P1 receives a tactile stimulation whenever she encounters either her fixed object, or the receptor field of participant P2, or the mobile object attached to the receptor field of P2 (from Lenay and Stewart, 2012).

Mentions: The pioneering study of minimalist perceptual crossing was proposed during the last decade (Lenay et al., 2006; Auvray et al., 2009). Two participants were using a technical device in order to interact in a virtual environment. By means of a computer mouse, each participant moves a receptor field laterally in a one-dimensional digital space, and the meeting of this field with any “object” in the environment activates an all-or-none tactile stimulation. Each participant can encounter three kinds of objects, each of which delivers strictly the same stimulation: the body-object moved by the other participant (which is superimposed on her receptor field), a fixed object and a mobile object. It is crucial to note that the mobile object is actually a lure attached to the receptor field of each participant by a rigid virtual link (see Figure 1).
