Neurophysiological and Behavioural Correlates of Coherent Motion Perception in Dyslexia
Taroyan, Naira A.; Nicolson, Roderick I.; Buckley, David
Dyslexia, v17 n3 p282-290 Aug 2011
Coherent motion perception was tested in nine adolescents with dyslexia and 10 control participants matched for age and IQ using low contrast stimuli with three levels of coherence (10%, 25% and 40%). Event-related potentials (ERPs) and behavioural performance data were obtained. No significant between-group differences were found in performance accuracy and response latencies of correct responses, for early (P1, N1, and P2) or late (P3) ERP peaks. However, attenuated early ERPs in the 10% coherent condition correlated significantly with lower performance accuracy (r = -0.66) and with the magnitude of literacy deficit (r = -0.46).
