ClinConnect Summary

This clinical trial is studying how our everyday experiences can influence our attention, particularly how we focus on different things around us. Researchers will use a mobile phone app to gather information about participants' daily lives and see how these personal experiences affect their attention. They will measure this by tracking eye movements and using brain imaging technology to observe how specific areas of the brain involved in attention are activated.

To be eligible for the study, participants need to be between 18 and 40 years old, right-handed, and must not wear glasses. They should have a compatible mobile phone and be willing to follow certain instructions for an MRI scan, which is a type of brain scan. It's important to note that individuals with certain medical histories, such as neurological or psychiatric conditions, or those taking specific medications, will not be able to participate. If you join, you can expect to engage in activities involving your mobile phone and undergo brain scans while researchers explore how your past experiences shape your attention.
