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 Private Object, or the Shared Object (SO), or the body-object moved by P2. Note that as illustrated on the right of the figure, the receptor field of P2 is oriented downward: this means that P2 can perceive only the objects (and the part of SO) located below the line, consequently being ignorant of the Private Object of P1.

Figure 2: Schematic illustration of the one-dimensional digital space explored by the participants. Participant P1 receives a tactile stimulation whenever she encounters either her Private Object, or the Shared Object (SO), or the body-object moved by P2. Note that as illustrated on the right of the figure, the receptor field of P2 is oriented downward: this means that P2 can perceive only the objects (and the part of SO) located below the line, consequently being ignorant of the Private Object of P1.

Mentions: For each trial, three fixed 2-pixel objects are placed along the one-dimensional space. One of these is jointly perceptible by both participants whereas the two others are private, that is to say that each is respectively perceptible by only one of the two participants (see Figure 2). In other words, for a given participant, two objects are perceptible for each trial: a shared one (SO, for Shared Object) and a private one (OwnPO, for Own Private Object). The private object of the partner is thus called OtherPO (for Other Private Object). The position of these objects varies for each trial.
