Table 2.
Multifactorial interaction comparisons (repeated measure ANOVA) and simple means comparisons (t-tests) of RWM errors. Sidak corrections used for t-tests with multiple comparisons. (* for a value indicates a significant paired difference, see significance column, * in a column title indicates a significant overall or interaction effect, as per RMANOVA.).
