Quantification of the P350 effects. Mean amplitudes of Identity (I), Variation (V) and Control (C) condition for all groups within 300–400 ms. Please note that for pre-reading preschoolers and reading preschoolers comparison was made in anterior regions; whereas for beginning readers comparison was made for left hemisphere regions (for further explanations, please refer to the text). Electrodes included in the mean amplitudes are displayed by black circles. Lines above bars indicate significant differences revealed by post hoc tests. Error bars indicate standard errors.
