Figure 1. A. Task Procedure.

Figure 1

Each trial began with a fixation screen containing a solid circle appearing at the center. Participants were required to maintain steady fixation for 500 ms, after which the fixation circle was replaced with a cue circle. The cue indicating target contrast was either High-contrast or low contrast. The screen was then blanked, followed by the search display which remained visible until a manual response was made. Participants indicated the presence of the gap at the top or bottom of the target item by pushing one of two buttons on a game controller. A 500-ms blank interval was interposed between the response and the onset of the next trial. Each participant underwent 160 trials with all four trial types randomized. B. Guided Visual Search and Response Process. This panel depicts the visual search process and attentional guidance to the target location prior to execution of a response.
