Trial Summary

What is the purpose of this trial?

The goal of this study is to investigate the finding that there are large individual differences in how participants move their eyes during active visual search. For example, some individuals tend to fixate, that is point their eyes steadily at a single location, for longer than other individuals before moving to another location. This experiment will use behavioral tasks to measure an individual's attentional and inhibitory functioning, and then see how each of these contributes to between-participant variability in eye movement behavior during visual search.

Eligibility Criteria

This trial is for individuals interested in how people use their eyes and attention during visual tasks. Participants should be willing to perform behavioral tasks that measure focus and self-control. Specific eligibility criteria are not provided, so it's open to a broad audience unless otherwise specified.

Exclusion Criteria

Uncorrected vision problems

I have a history of neurological illness.

Treatment Details

Interventions

• Visual tasks

Trial Overview The study is examining individual differences in eye movements during visual search tasks. It aims to understand why some people fixate longer on one spot before moving their eyes compared to others by measuring attentional control and inhibition.

Participant Groups

Group I: Study Group Experimental Treatment 1 Intervention

This study examines eye movement behavior using eye-tracking technology. Healthy participants perform three different tasks, including a visual search task, a stop-signal task, and a useful field of view task. Behavioral performance and eye movements are recorded for all tasks.
