Experimental task and performance. A, Each trial began with the presentation of four trial-unique flanker faces, followed by an identical target face in the center of the array, and participants had to classify the viewpoint direction of the target face with a button press. Target and flanker face-viewpoint direction was congruent in half of all trials (shown here in the first trial) and incongruent in the other half (shown here in the second trial). The proportion of congruent to incongruent stimuli (conflict frequency) was manipulated in a context-specific manner according to stimulus location: one side of fixation was associated with 75% congruent trials (low-conflict context) and the other side with 75% incongruent trials (high-conflict context). B, Group mean RTs and error rates (C; ±SEM) are plotted for congruent and incongruent trials as a function of the contextual conflict frequency manipulation.
