Abstract

Recently, Cestnick and Coltheart (Cognition 71 (1999) 231) have reported evidence of abnormal performance on the Ternus apparent motion task in dyslexics. We demonstrate that some aspects of their data may be accounted for by more frequent lapses of concentration in the dyslexic group than in controls. We then report on a study in which a modification of the Ternus procedure was employed to simplify the task and to control for the effects of inattention. The results suggest that dyslexics do genuinely differ from normal readers in their perceptual processing.
