Change in SDT variables (difference scores) for the overall sample and separated by condition.

Note: Changes over time were examined using intercept-only multilevel models; differences between conditions were tested using multilevel univariate models, with condition as the sole predictor. Significance for change over time is noted in the “Overall” columns; differences across condition are noted in the BWL/SDT-WL columns.
