There was a highly significant effect of time (F (5, 153) = 12.80, p < 0.0001) and treatment (F (1, 34) = 4.892, p = 0.0338), but no significant interaction (F (5, 153) = 1.584, p = 0.1677) over the 6-week period indicating that the animals learned the rules of the task, with anthocyanin-rich extract fed animals performing better than the control fed animals.
