Developmental dyslexia is a heterogeneous disorder that has been associated with deficits in various cognitive domains, such as memory and attention. The aim of the present study was to investigate possible deficits in memory and attention in students with developmental dyslexia. The sample consisted of 50 students (mean age 10.5 years), including 25 students diagnosed with dyslexia and 25 typically developing controls matched for age and gender. Participants were assessed using tests of short-term phonological memory, long-term memory, working memory, immediate verbal memory, auditory and visual memory, as well as auditory and visuospatial attention. The results revealed that students with dyslexia exhibited statistically significant deficits in all memory tests. In the attention domain, statistically significant deficits were observed in the visuospatial attention test but not in the auditory attention test. These findings support multiple-deficit models of dyslexia and suggest that memory and attention impairments may collectively contribute to the understanding of the cognitive profile of students with developmental dyslexia.
