title: Observation and action priming in anticipative tasks implying biological movements.
abstract: The purpose of this study was to assess the effect of short-term priming in perceptual anticipation tasks involving point-light biological motions. After the production or the observation of a relevant or an irrelevant movement (action vs. observation priming), 11 right-handed volunteers were asked to anticipate, as quickly and accurately as possible, the end point of a pointing movement after the stimulus vanished upon completion of 60% of the total movement. Our results indicate that perceptual accuracy is significantly affected only with relevant observation priming. This suggests that perceptual anticipation tasks' involving point-light biological motions implies specific perceptual competencies. (PsycINFO Database Record (c) 2013 APA, all rights reserved).
