Mean values (standard deviation). HF/ND: hypofunctional/nondominant arm; F/D: functional/dominant arm. The two methods did not differ in estimating the SSRT for each used arm in each experimental group, and their average was used for SSRT comparisons between groups and arms. T-tests comparisons between the methods are reported. Two-way ANOVA (factors: gender, arm) revealed no gender differences between female and male controls (main effect gender: F(1,20) = 2.56, p = 0.13; main effect arm F(1,20) = 0.10, p = 0.76; interaction between gender and arm: F(1,20) = 1.03, p = 0.37).
