+
After Bonferroni correction, group difference significant in ANOVA/ANCOVA controlling for IQ (for % intensity scores only) and in Wilcoxon-Mann-Whitney test (for % accuracy scores only).
*
Group difference significant in ANCOVA controlling for overall perceptual sensitivity (no longer significant after Bonferroni correction).
