English abstract The relationship between gaze behavior and postural stability under distinct cognitive loads is still unclear in children. This study focuses on eye movements' effect on the children's postural stability by varying the visual tasks' attentional/cognitive demands. Twenty young adults (23.4 years-old, ± 2.1) and sixteen children (10.3 years-old, ± 0.4) stand in semi-tandem position on a force plate, wearing a head-mounted eye-tracking while performing three 40 second-trials in the following order: stationary gaze task; free-viewing task; and visual searching task. Children showed a higher number of fixations during the stationary gaze task (p<0.0001), butthis number was lower during free-viewing (p<0.004) and visual searching tasks (p<0.0001) when compared to young adults. Total fixation duration was lower in children than in young adults (p<0.0001) and higher during stationary gaze task than free-viewing(p<0.0001) and visual searching tasks (p<0.0001) for both groups. These results indicate that the performance of the visual searching task during the maintenance of a challenging stance may deteriorate children’s postural stability suggesting that the relationship between gaze behavior and postural control is not well developed around the age of 10 years
