Table 2 presents the mean for the percentage changes of
the auditory and visual choice and complex choice RTs. It
should be noted that positive numbers represent improve-
ment in the RTs. In the experimental group, the highest
mean percentage change was 21.84% for auditory complex
choice RT and the lowest value was 5.14% for visual choice
RT. The mean percentage changes of the auditory choice and
complex choice RTs were statistically significant between
two groups (P Z 0.02, P Z 0.04, respectively) (Table 2).
