Experiment 2: One Target in Many Situations (NCT06934148)
Prevalence Effects in Visual Search: Theoretical and Practical Implications (H)
🩺 Plain-English Summary (8th-Grade Level)
The goal is to look for qualitative differences in visual search behavior when one search is performed many times in a row compared to when multiple search tasks are intermixed. Four search tasks are tested. The target is the same in every task but the types of distractors change from task to task. In the Mixed condition, the four tasks are randomly changed from trial to trial. In the Blocked condition, each task is run as a block of 100 trials.
