Study 1 Stimuli and ERP results. (FIRST ROW) The nine trial types used in Study 1 were three levels of prime (same, different, none) × three levels of feature (faces, eyes, mouth). (SECOND ROW) Grand-average ERPs (N = 24) across electrodes P₈, P₁₀, TP₈, P₇, P₉, TP₇. The time period of the P100 is indicated by the area with downward slashes. NOTE: this figure displays the waveform across the electrodes listed above, whereas the P100 statistics were done on the average waveform of electrodes C₁, C_z, C₂. The time period of the N170 is indicated by the solid shaded area. The time period of the N250r is indicated by the area with upward slashes. The waveforms are color coded such that RED is the prime_same condition, GREEN is the prime_different condition and BLUE is the prime_none condition. (THIRD ROW) Topographical maps of the N250r priming effect at each cell of the feature factor. The ‘Same’ maps display the prime_samevs prime_none simple contrast, whereas the ‘Different’ maps display the prime_differentvs prime_none contrast. (FOURTH ROW) N250r mean amplitude differences across electrodes P₈, P₁₀, TP₈, P₇, P₉, TP₇. The contrasts displayed are the same as for the topographical maps. Error bars indicate the 95% confidence interval. Asterisks indicate significant priming effects, P < 0.05.
