Visual attentional blink in dyslexic children: Parameterizing the deficit
نویسندگان
چکیده
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.

Children with dyslexia: evidence for visual attention deficits in perception of rapid sequences of objects
The attentional blink (AB) refers to a decrease in accuracy that occurs when observers are required to identify, detect or classify the second of two rapidly-sequential targets. The AB is typically attributed to an inability to rapidly reallocate attentional resources from the first to the second target. Thus, it provides an ideal tool to investigate how visual attention is rapidly allocated to...
متن کاملA case study of developmental phonological dyslexia: Is the attentional deficit in the perception of rapid stimuli sequences amodal?
The attentional blink (AB) refers to a decrease in accuracy that occurs when participants are required to detect the second of two rapidly sequential targets displayed randomly in a stream of distracters. Dyslexic individuals have been shown to exhibit a prolonged AB in the visual modality, interpreted as evidence of sluggish attentional shifting (SAS). However, the amodal SAS theory predicts t...

The goal of this study was to evaluate the possibility that dyslexic individuals require more working memory resources than normal readers to shift attention from stimulus to stimulus. To test this hypothesis, normal and dyslexic adolescent participated in a Rapid Serial Visual Presentation experiment (Shapiro, Arnell, & Raymond, 1997). Surprisingly, the result showed that the participants with...

متن کاملNo differential attentional blink in dyslexia after controlling for baseline sensitivity
Previous research has associated a prolonged attentional blink (AB) with adult dyslexia [Hari, R., Valta, M., & Uutela, K. (1999). Prolonged attentional dwell time in dyslexic adults. Neuroscience Letters, 271, 202-204]. The AB represents a limitation in temporal information processing, estimated as the time interval between two targets necessary for accurate recall (e.g., [Raymond, J. E., Shap...
