Mean classification accuracy rates in unsmoothed data and at three different levels of spatial smoothing. Smoothing was carried out using Gaussian kernels of either 4, 6 or 8 mm FWHM. The effect of smoothing varied across regions, producing a decrease in classification accuracy in A1 and M1, but an increase in accuracy in V1. Error bars represent 1 standard error of the mean (calculated across participants).
