Impact of audio on navigation strategies in children and adults with dyslexia

Abstract

Children and adults with dyslexia are often provided with audio-support, which reads the written text for the learner. The present study examined to what extent audio-support as a form of external regulation impacts navigation patterns in children and adults with and without dyslexia. We compared navigation patterns in multimedia lessons of learners with (36 children, 41 adults), and without dyslexia (46 children, 44 adults) in a text-condition vs. text-audio-condition. Log files were recorded to identify navigation patterns. Four patterns could be distinguished: linear reading (linear), linear reading with rereading (big peak), reading with going back to previous pages (small peaks), and a combination of strategies (combined peaks). Children generally used linear navigation strategies in both conditions, whereas adults mostly used combined-peaks strategies in the text-condition, but linear strategies in the text-audio-condition. No differences were found between learners with and without dyslexia. Audio-support does not impact navigation strategies in children but does seem to impact navigation strategies in adult learners, towards the use of more linear navigation patterns, reflecting less self-regulation.
