Objectives and Key Themes

This study investigates the effects of continuous social exclusion, experienced in a virtual ball tossing game called Cyberball, on the P300 event-related-potential (ERP) component. The objective is to analyze the P300 amplitude and latency in response to inclusion and exclusion conditions using a single-trial analysis approach.

• The psychological effects of social exclusion (ostracism)
• The brain's response to social exclusion as measured by the P300 ERP component
• The influence of single-trial analysis on the understanding of the P300 in relation to social exclusion
• The development and validation of a method to analyze the P300 component using single-trial data
• The implications of these findings for understanding social exclusion and its impact on individuals

Chapter Summaries

• Introduction: This chapter provides a comprehensive overview of social exclusion and its effects. It introduces the concepts of ostracism, paradigms that trigger feelings of exclusion, and the Need Threat Model. Additionally, it discusses the role of event-related-potentials (ERPs), particularly the P300 component, in understanding the brain's response to social exclusion.
• Materials and Methods: This chapter details the methodology employed in the study. It outlines the participants, experimental design, Cyberball paradigm, EEG recording procedures, and data analysis methods.
• Results: This chapter presents the findings of the study. It analyzes the effects of time and group on the P300 amplitude and latency, and investigates the influence of probability models on the P300 amplitude.
• Discussion: This chapter interprets the results in light of previous research on social exclusion and the P300 ERP component. It discusses the significance of the findings, limitations of the study, and potential future research directions.
