Social Feedback Evaluation for Schizotypal Traits

This trial explores how young adults with different schizotypal traits (patterns of unusual thinking or behavior) process social acceptance and rejection. Participants will attend a single lab session to answer questions while researchers record their brain activity using EEG, a noninvasive method that tracks electrical activity in the brain. The study examines how brain responses differ when individuals expect to be liked or disliked and how these responses relate to schizotypal traits. This research does not involve any treatment or medication testing. Young adults aged 18 to 35 who can complete an EEG session are suitable candidates for this trial. As an unphased trial, it offers participants a unique opportunity to contribute to understanding social processing in young adults without involving treatment.

In a previous study, researchers examined how individuals handle acceptance or rejection using the Social Judgment Paradigm. This method is safe for participants and involves considering whether someone will like or dislike them, followed by feedback. It is noninvasive, requiring no surgery or intrusive procedures. No harmful effects have been reported from this type of study. Participants typically wear sensors on their scalp to measure brain activity, a safe and common research practice. These studies enhance understanding of reactions to social situations without posing risks to participants.¹²³⁴⁵

Unlike traditional treatments for schizotypal traits, which often rely on medication or long-term therapy, the Social Judgment Paradigm offers a fresh approach by focusing on real-time social feedback processing. This method exposes participants to different social feedback scenarios—like acceptance or rejection—while monitoring brain activity through EEG. Researchers are excited because this could reveal new insights into how people with schizotypal traits process social interactions, potentially leading to more effective, personalized treatment strategies.

Research shows that people with schizotypal traits think and react differently in social situations. Those with schizotypal personality disorder (SPD) exhibit increased brain activity when detecting social cues, indicating they experience social situations differently from others. Studies also find that individuals with strong schizotypal traits may struggle with social interactions, such as predicting others' responses. In this trial, participants will complete the Social Judgment Paradigm (SJP) to study brain responses during social feedback. Understanding these differences will enhance knowledge of how people with schizotypal traits process social information.⁶⁷⁸⁹¹⁰
