Figure 2

(a) Time plots showing the ERPs evoked by faces and flowers (collapsed across the valid, invalid and no-cue conditions) over occipito-temporal electrodes, along with significant clusters of the difference between the two conditions (Monte-Carlo P value<0.05). (b) Bar plots illustrating voltage differences for the three components of interest (P1, P400 and LSW, see Supplementary Fig. 1). For each component, two-tailed pair-wise comparisons (n=28 subjects) were performed on signal amplitudes for face (Fa) and flower (Fl) target stimuli (asterisks denote *P<0.05 and **P<0.01; Error bars show s.e.m.). (c) Scalp topographies showing the voltage ERPs evoked by face and flower trials for each temporal window of interest (top row), and their difference in terms of statistical maps (Z-scores; bottom row).
