Study Summary

This trial aims to understand how the brain processes different visual features like color and motion to identify important locations in a scene. The researchers will use functional MRI scans on healthy participants to study how the brain regions

Who is the study for?

This trial is for healthy individuals interested in how the brain processes visual information. Participants should be willing to undergo fMRI scans and perform visual tasks that involve discriminating colors or motion of stimuli. Specific eligibility criteria are not provided, but typically participants would need to have no contraindications to fMRI.Check my eligibility

What is being tested?

The study examines how certain brain regions process and prioritize visual features like color or motion when performing a task. Using advanced imaging (fMRI) and analysis techniques, researchers will track how these regions create 'feature dimension maps' that guide attention in complex scenes.See study design

What are the potential side effects?

There are generally minimal side effects associated with participating in this type of cognitive neuroscience study. The main risks come from the fMRI procedure which can include discomfort from lying still, loud noises during scanning, and potential claustrophobia.

Experimental Treatment

Group I: Manipulations of task demands (Expt 2.1)Experimental Treatment1 Intervention

Participants will view a single stimulus containing dots moving in one of two directions (clock-wise or counterclockwise) and drawn in one of two colors (orange and cyan). To complete the correct task for a trial, a cue at fixation will be manipulated.
