Timeline showing the progression of events for a single visual search trial. Participants were shown the target image(s) and progressed to the next screen upon key press. Next, a fixation cross was displayed and automatically cleared from the screen following 1-second fixation. The visual search array was then presented, and terminated upon spacebar press. Finally, target presence was queried, followed by 1-second accuracy feedback, and a 1-second delay prior to the start of the next trial.
