This study will examine how young adults with different levels of schizotypal traits process social acceptance and rejection. Participants between 18 and 35 years old will complete a single laboratory session that includes questionnaires and electroencephalography (EEG), a noninvasive method that measures electrical brain activity through sensors placed on the scalp. During EEG recording, participants will complete a computer-based Social Judgment Paradigm (SJP) in which they form expectations about whether another person will like or dislike them and then receive experimentally controlled acceptance or rejection feedback. The study will examine how brain responses differ when social feedback is expected versus unexpected and whether these responses vary with schizotypal traits. The goal is to better understand the brain mechanisms involved in evaluating social feedback. This study does not provide treatment and does not test a drug or medical device.
Schizotypal traits occur along a continuum in the general population and are associated with differences in social functioning and social information processing. This study will investigate neural responses to social feedback in young adults across the schizotypy spectrum using electroencephalography (EEG). Participants between 18 and 35 years old will complete a single experimental session. During EEG recording, they will perform a Social Judgment Paradigm (SJP) in which they first form an expectation about whether another person will respond positively or negatively toward them and subseque…
Inclusion Criteria: * Ages 18-35 years. * Able to provide informed consent. * Able to complete an EEG recording session. Exclusion Criteria: * Younger than 18 years or older than 35 years. * Unable to provide informed consent. * Unable to complete the EEG recording session. * No additional exclusion criteria are applied.
A computerized Social Judgment Paradigm in which participants receive experimentally controlled social feedback (acceptance/rejection) from purported peers or evaluators while continuous EEG is recorded to assess oscillatory activity and event-related potentials associated with social feedback processing. Feedback valence and expectancy are manipulated at the trial level, with trial order randomized within the task.
