Overall, the performance of nonvisually deprived participants remained relatively constant between the pretest and posttest, whereas the visually deprived participants exhibited an improvement in performance during their second discrimination test. More specifically, 31 of the 32 visually deprived participants showed an improvement in their discrimination threshold, ranging from 7-85% (M = 28.7%) relative to their initial discrimination score. A 2 x 2 analysis of variance (ANOVA) with group (Group 1: control; Group 2: visually deprived) as the between subjects factor and condition (Condition 1: before visual deprivation; Condition 2: after visual deprivation) as a within-subject factor was conducted. The interaction between factors was significant, reflecting group-specific changes from pretest to posttest. Post hoc tests with Bonferroni correction revealed no significant difference in the ability to discrimination auditory stimuli prior to visual deprivation between the two groups, t(62) = -0.026, p = .979. Result from the subsequent testing session revealed significant improvement for the visually deprived individuals’ discrimination ability compared to the nonvisual deprived group, t(62) = 3.786, p
