Full Self: Completeness Cues Enhance Self-Prioritization

Self-related information is of great significance to human survival and development. The present study, through two experiments, used the perceptual matching paradigm to examine the effect of complete/incomplete shapes on self-processing. The behavioral results of Experiment 1 showed that, under the matching condition, compared with self-incomplete association and stranger-complete association, self-complete association had faster reaction times, higher accuracy rates, and more liberal response criteria; moreover, self-complete association had a faster information uptake rate and a shorter non-decision time. The ERP results showed that, under the matching condition, compared with self-incomplete association and stranger-complete association, self-complete association elicited smaller N1 and N2 amplitudes...
