Right impairment of temporal order judgements in dyslexic children.
This study investigates the spatial bias of visual attention measured by a temporal order judgement (TOJ) task and the influence of a high attentional load condition in a group of dyslexic children compared to a control group with normal reading skills (each group N=10). The TOJ task (T2) was placed after a shape discrimination task (T1). In a low attentional load block participants worked only on T2, whereas in the high attentional load block they were required to process both T1 and T2. Several t-tests were executed to compare performance between conditions and groups. In the low attentional load conditions, results in dyslexic children were significantly impaired for the right visual field compared to a control group. The high attentional load conditions did not enhance these effects and seems to provoke the same leftward bias in the control group.
