Three-dimensional topographical maps (posterior view) of summed corrected amplitudes of the expression-change response as a function of expression intensity averaged across emotions for both healthy controls (top) and 22q11DS individuals (bottom). Center: the same data displayed averaged across regions of interest (ROIs) showing the expression-change response (F) surrounded by ±0.5 Hz of summed corrected amplitude spectra. Shadowed areas represent standard errors of the mean. Z-scores displayed next to each map indicate the significance of the response for each group and each expression intensity (*p < .05, ***p < .001). While the expression-change response is non-significant and practically absent for both groups of participants when emotions are expressed at low intensity, it progressively emerges as expression intensity increases with significant responses for both groups at moderate and high intensities. However, it is significantly lower in 22q11DS participants with a magnitude corresponding to 64% of the response observed for healthy controls
