Abstract Autism spectrum disorder (ASD) is characterized by a range of symptoms, including restrictive behaviors and deficient social skills. We investigated EEG correlates attention, face, non-face perception applying continuous performance test (CPT) with two different sets stimuli (letters faces). The CPT required participants to respond specific target stimulus (e.g., “X”) only when it followed preceding “O”). Event-related potential (ERP) components, P100, N170, P200, N250, P300, negative variation (CNV), were analyzed in 19 young adults ASD typically developed (TD) individuals that matched for intelligence, age, gender. TD had higher accuracies the condition regardless type. No ERP differences between groups found letter stimuli. By contrast, autistic exhibited lower amplitudes P300 CNV during face CPT. Results suggest diminished allocation attentional resources response preparation towards socially relevant

Musicians have an advantage in recognizing vocal emotions compared to non-musicians, a performance often attributed enhanced early auditory sensitivity pitch. Yet previous ERP study only detected group differences from 500 ms onward, suggesting that conventional analyses might not be sensitive enough detect neural effects. To address this, we re-analyzed EEG data 38 musicians and 39 non-musicians engaged emotion perception task. Stimuli were generated using parameter-specific voice morphing preserve emotional cues either the pitch contour (F0) or timbre. By employing decoding framework with Linear Discriminant Analysis classifier, tracked evolution of representations over time signal. Converging study, our findings reveal musicians—but non-musicians—exhibited significant between 900 after stimulus onset, pattern observed for F0-Morphs only. These results suggest musicians’ superior recognition arises more effective integration information during later processing stages rather than sensory encoding. Our also demonstrates potential approaches brain activity as biological sensor unraveling temporal dynamics perception.
