Mean reaction time (in seconds) of individuals of each treatment for each observation time between 8 and 50 days after rehydration (n = 11 observations). SD has been removed for clarity. Time affected significantly the reaction time (p < 0.05; mixed ANOVA). The interaction between time and treatments did not caused significant differences (p > 0.05; mixed ANOVA). Letters in right indicate significant differences in reaction time between treatments (p < 0.001; Student t pairwise with Bonferroni correction).
