From: Face expectancy cues differentially modulate conflict processing driven by emotional incongruence: an EEG study

Fig. 6

Time–frequency representations of event-related spectral perturbations (ERSPs) at the parietal cluster (P1, P2, Pz) for the Label-first (A) and Face-first (B) conditions. At − 1000 ms, the expectancy cue appears (letter in A, face in B); at 0 ms, the face and label overlap, marking conflict onset. The color scale (dB) indicates power changes relative to a common pre-event baseline. Consistent with the linear mixed-effects results, alpha and beta power show a Condition × Period interaction: in the Label-first condition, desynchronization is strongest during conflict, whereas in the Face-first condition, pronounced desynchronization is already present during the expectancy period with little additional change at conflict.
