Fig. 5
Univariate analysis results. a Left panels represent ERP group differences (T values) across time in those electrodes that formed a significant cluster during object presentation, locked to the onset of the stimulus. Top left panel shows the contrast of photographs vs. line drawings, and the bottom left panel differences between animate vs. inanimate objects. Scalp figures next to each contrast illustrate the maximum cluster’s topography, averaged across the significant time-window, with all significant electrodes in a cluster being marked with an asterisk. b Right panels show ERP group differences (T values) over time in those electrodes that are contained in the maximum significant clusters during memory retrieval, time locked to participants’ responses. The top right panel shows the perceptual contrast, and the bottom right panel the semantic contrast. Cluster topographies for each comparison are located next to each panel, and the temporal extent of significant clusters is shaded in colour
