Summary

This trial aims to understand how our brain determines what to focus on in our visual environment. Researchers will have participants look at displays with colored shapes and moving dots and report specific aspects of the visual stimuli.

Who is the study for?

This trial is for individuals interested in how we pay attention to important objects in our environment. Participants should be able to look at displays and report on visual stimuli. There are no specific inclusion or exclusion criteria provided, suggesting it may be open to a wide range of volunteers without particular health conditions.Check my eligibility

What is being tested?

The study tests how the presence of distracting stimuli and cues about location relevance affect our ability to focus on salient objects. It involves looking at colored shapes or moving dots and reporting details like line orientation, with response times being measured.See study design

What are the potential side effects?

Since this is a behavioral study involving visual tasks, there are likely no direct physical side effects from participating. However, participants might experience eye strain or mental fatigue from focusing on visual tasks during the experiment.

Experimental Treatment

Group I: Manipulations of Relevant Locations (Expt 3.1 Pilot)Experimental Treatment3 Interventions

Participants will complete a visual search task in which they will covertly search for a unique target item based on a specific feature dimension indicated at the start of the experiment (unique color, unique motion direction, unique shape) in an 8 item array. At the beginning of each trial, participants will be visually cued (e.g., an arrowhead around fixation) to the side of the display the target item will appear (left, right, up, down). A proportion of all trials will contain a task-irrelevant, singleton distractor defined in a non-target dimension (e.g., color target and motion distractor)
