Being able to classify experienced emotions by identifying distinct neural responses has tremendous value in both fundamental research (e.g. positive psychology, emotion regulation theory) and applied settings (clinical, healthcare, commercial). We aimed decode the representation of experience two discrete emotions: sadness disgust, devoid differences valence arousal. In a passive viewing paradigm, we showed evoking images from International Affective Picture System participants while recording their EEG. then selected subset those that were either or disgust (20 for each), yet indistinguishable on normative Event-related potential analysis 69 differential N1 EPN components support-vector machine classifier was accurately (58%) whole-brain EEG patterns experiences.
