Child Gap Overlap Task - Prosaccade

The Gap-overlap task is a gaze contingent paradigm that measures visual attention shifting between a central and a peripheral stimulus. This is thought to be a key process underlying behavioral control. The Gap-overlap task contains three conditions; i) Gap, in which the central stimulus disappears 200ms before the appearance of the peripheral target; ii) Baseline, in which the central stimulus disappears simultaneously with the appearance of the peripheral target; iii) Overlap, in which the central stimulus remains on screen during peripheral target presentation. In the prosaccade version of the task, which is followed by the antisaccade version of the task, children are instructed to look at the peripheral stimulus appearing on the screen. During the task, a Tobii TX300 eye-tracker records eye movements at 300 Hz. Key dependent variables are latency to shift attention to the peripheral stimulus in the Gap vs Baseline conditions (Facilitation) and Gap vs Overlap conditions (Disengagement).

Data were collected up until May 2022. An infant version of the the Gap Overlap - Prosaccade task was conducted in YOUth Baby and Child at 5 months, 10 months and 3 years old.
