This study examined whether audiovisual computer training without linguistic material had a remedial effect on different learning disabilities, like dyslexia and ADD (Attention Deficit Disorder). This study applied a pre-test-intervention-post-test design with students (N = 62) between the ages of 7 and 19. The computer training lasted eight weeks occurring twice a week for 15 minutes per session. After the training period, an improvement in the auditory-visual matching test was found. According to the hypothesis of this study, the youngest children with dyslexia would benefit most from the intervention. However, the training had also a positive effect on auditory-visual matching with older students with dyslexia. Surprisingly, the students with ADD benefited from this intervention. According to the teachers, this intervention had also a positive effect on the students' school behaviour.
