N2 - 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., Shapiro, K. L., & Arnell, K. M. (1992). Temporary suppression of visual processing in an RSVP task: An attentional blink? Journal of Experimental Psychology: Human Perception and Performance, 18, 849-860]). Utilizing single- and dual-target procedures, this investigation extended upon previous research. When controlling for baseline sensitivity as estimated in the dual-target condition, there was no significant difference between dyslexic and control performance. Finding no evidence of a single-target task difference or prolonged AB effect in dyslexia, it is suggested that baseline sensitivity differences relate to difficulties with task demands in dyslexic readers.
