Evolution of the EEG responses across successive AAAAB patterns. The time points were obtained using a sliding FFT (6.25-s time window with 0.625 s steps). For both the contrast (top) and base responses (bottom), the amplitude remained stable over time, except in the conditions with large contrast where a transient increase in amplitude was also observed, spanning 3–10 s after the onset of the sequence, followed by a significant decrease (in red, experiments 1 and 2; top).
