| description | ObjectiveThis study aims to investigate the impact of stimulus environments (Virtual Theatre vs Monitor) and error probabilities (20% vs 50%) on attentional states, Error Potentials (ErrP), and machine learning classification performance.ApproachEEG signals were recorded using different protocols, and features were extracted for subsequent analysis from single-trial response and attention level was computed from the second preceding error processing stimulation.ResultsThe results indicate significant differences across conditions: the Monitor environment consistently elicited higher and faster ErrP responses and elevated attentional states compared to Virtual Theatre. Additionally, classification performance in the Monitor environment outperformed Virtual Theatre consistently. Further analysis revealed that the 20% error probability protocol yielded increased ErrP responses, heightened attentional states, and superior classification performance compared to the 50% protocol. Classification performance under the 20% error probability condition consistently exceeded 75% validation and test sets. Moreover, a significant correlation between attention-related features and ErrP characteristics was observed, highlighting the intricate relationship between error processing and attentional engagement.RelevanceThese findings underscore the importance of considering stimulus environments and error probabilities in cognitive neuroscience research and machine learning applications. Understanding these factors can inform experimental design and model development, ultimately advancing our comprehension of cognitive processes and enhancing real-world applications of machine learning algorithms. |
