Color Change Detection Task

This EEG dataset comprises electrophysiological recordings from 53 subjects performing a bilateral change-detection task designed to investigate how perceptual grouping based on color repetition influences visual working memory (VWM) processing. Using event-related potentials (ERPs), the study temporally isolates neural correlates of distinct VWM stages—individuation encoding, maintenance, initial comparison, percept-memory comparison, and decision making—through specific ERP markers (N2pc, CDA, N2, FN400). The dataset includes 1,248 trials recorded at 512 Hz from a 71-channel BioSemi ActiveTwo system and is structured according to BIDS standards.
