ALT Faces have so much information in them! You can learn all sorts of things from looking at a person’s face. But how does your brain react to seeing different types of faces? In our study, you will make judgements about faces presented on a computer screen while your brain activity is measured using a non-invasive brain imaging technique! The session will take between 1 and 1.5 hours, and you will receive $22.50 upon completion as a thank you for your time. Appropriate protocols and guidelines are in place for the safety of all participants. Please check to see if you fit the eligibility criteria to participate in this study: • Are Caucasian (to be able to match our current stimuli, as we are using Caucasian faces ) • Between 16 and 65 years of age • Do not suffer from epilepsy and/ or migraines, as participants will be required to view images shown rapidly • It is recommended that those in vulnerable populations should not participate at this time
