Visual and temporal processing are abilities recognized as important components of the reading process. In an attempt to replicate and extend the findings of previous studies investigating these abilities in children and adults with reading disability (RD), the present study investigated visual and temporal processing abilities in an RD sample in the process of special educational remediation. Participants were 36 students, aged 12 to 18 years, from a school for youth with learning disabilities. Group formation was based on previous formal diagnoses of RD. The children were tested on measures including the Useful Field of View test (UFOV), a multiple object tracking task, temporal order judgment tasks, a phonological task, and an orthographic task. The influence of age and special education were examined to determine their role in performance on all measures. The RD group performed significantly worse than the comparison group on phonological processing accuracy, and orthographic processing reaction time and accuracy. There were no reliable differences between groups on the visual processing or auditory temporal processing tasks, but the RD group was slower than the comparison group on the visual temporal processing task. Potential explanations are suggested for discrepancies with previous studies examining these abilities in children varying considerably in age and educational opportunities.
