Treatment effects on n-back performances independent of WM-load load and Post-hoc tests for each WM-load separately.

Note. * p post-hoc tests. ME = Main effect. There was a significant interaction between load and stimulation on delta ACC n-back performance. The interaction of age and load as well as sex and load were included as covariates. Post-hoc tests revealed a significant stimulation effect on 2-back performance only. For the Post-hoc tests only the main effects for sex and age were included as covariates, but not the interaction terms WM-load by sex and WM-load by age.Treatment effects on n-back performances independent of WM-load load and Post-hoc tests for each WM-load separately.
