Visual attentional blink in dyslexic children: Parameterizing the deficit.
The parameters generated by a curve fitting method on the visual attentional blink (AB) of 14 dyslexic and 14 control children were compared. The two groups differed on AB minimum parameters, whereas both AB duration and AB amplitude parameters were the same. The results suggest that low AB minimum is associated with poor reading. Moreover, phonological awareness was found to correlate with visual AB parameters in the dyslexic group. Overall, the present study provides new methodological insights regarding the assessment of the AB and visual sequential processing in relation to reading disorders.
