« Moi d’abord ! » ou l’égocentrisme ordinaire : Une revue critique de l’effet de priorité au Soi.

Abstract

The self is a crucial component of the psychic life and plays a central role for the adaptation to the environment. In daily life, this adaptative function is ensured, inter alia, by numerous biases filtering information and favoring those which are self-related. After succinctly reviewing the most documented among them which are affective and mnesic biases, the current paper provides a critical review of literature about a bias which is supposed to be perceptive, the self-prioritization effect (SPE). That has been revealed by Sui et al. (2012, Journal of Experimental Psychology: Human Perception and Performance, 38(5), 1105) with an astute matching task and consists in the fact that arbitrarily tagging shapes to a word referring to the participant (e.g., you-square) leads to faster and more accurate responses as compared to shapes tagged to a word referring to another identity (e.g., strange-circle). The methodological variations of this task and the SPE's both extension and putative origins will be presented, as well as the restrictions which border it, related to the individuals, to the experimental situation and to some more general properties of the self. Finally, some avenues for future research will be proposed, drawing some promising paths: beyond being a robust and intriguing phenomenon, SPE can indeed be considered as a convenient tool to assess some mechanisms underlying social cognition, in various fields using an experimental approach such as developmental psychology and social psychology.
