Objective: The objective of the current study was tripartite; first, to establish the impaired face processing of dyslexic readers in a large sample; secondly, to assess whether the hypothesized perceptual impairment of dyslexic readers is specific to higher order visual processing; lastly, to determine whether the proposed higher level visual processing deficits of dyslexic readers extend to the perception of novel objects. Research suggests that dyslexic readers are impaired at the perception of faces and other complex objects. Therefore, it would be expected that dyslexia might stem from a deficit within the higher visual system. Method: 32 diagnosed dyslexic readers (M=26.3 years) and 32 matched typical readers (M=26.1 years) participated in the study. Performance was measured on the FYS-test, which involves three separate discrimination tasks, each with different stimuli: faces (F), novel computer-generated objects called YUFOs (Y) and scrambled faces (S). Results: Dyslexic readers have impaired face perception compared to typical readers, but do not have complications with perceiving novel objects or scrambled faces. Conclusion: Reading difficulties in dyslexia might partially be caused by deficits in higher level visual processing, specifically in the perception of familiar objects such as words and faces.
