WRAM performance for Training (pre-treatment). (a) Across the 12 days of baseline testing, there was a main effect of Age, where Middle-Aged animals made more total errors than Young animals collapsed across all days of testing. (b) Average total errors (ln) per trial were evaluated for the asymptotic phase of testing (D7–12). Trial 3 alone, a higher working memory load trial, revealed a main effect of Age, where Middle-Aged animals made more errors than Young animals (* = p<0.05).
