P	0.019^*	< 0.001^*	< 0.001^*	< 0.001^*

Data was expressed using Mean ± SD. SD Standard deviation
Mean with Common letters are not significant (i.e. Means with Different letters are significant)
F F for One way ANOVA test, Pairwise comparison bet. the Post Hoc Test (Tukey) was used in each of the two groups
p p value for comparing between the studied Reaction time
^* Statistically significant at p ≤ 0.05
