Investigating visual search behavior in different task conditions
Prevalence Effects in Visual Search: Theoretical and Practical Implications (H)
NA · Brigham and Women's Hospital · NCT06934148
This study is testing how people search for things visually when they do the same task over and over versus when they switch between different tasks.

What this trial studies
This experiment aims to explore how visual search behavior differs when participants perform the same search task repeatedly versus when they are presented with mixed tasks. Four distinct search tasks will be tested, with the target remaining constant while the distractors vary. Participants will engage in either a Blocked condition, where they complete a set number of trials for each task, or a Mixed condition, where tasks are randomized. The findings could provide insights into real-world visual search processes compared to traditional lab methods.
Who should consider this trial
Good fit: Ideal candidates for this study are individuals who can pass the Ishihara color vision test and have normal vision of 20/25 or better with correction.
Not a fit: Patients with a history of neuromuscular or visual disorders may not benefit from this study.
Why it matters
Potential benefit: If successful, this research could enhance our understanding of visual attention and improve strategies for tasks requiring visual search.
How similar studies have performed: While similar studies have explored visual search, this specific approach of comparing blocked versus mixed tasks is relatively novel.
