Visual representations must support both robust and rapid object processing, yet how these representations develop remains unclear. Here, we used electroencephalography (EEG) and multivariate analyses to characterize visual representations emerging during passive viewing of everyday objects, from infancy to adulthood (total N=190) from 0.5 years to adulthood in a cross-sectional study. We observed that the peak latency of object decoding decreased with age, indicating faster processing. Time generalization analysis revealed increasingly persistent representations with age. Together our results provide a first comprehensive cross-sectional view of the neural dynamics with which object representations emerge during development.
