Practice effects on the modified Concept Shifting Task (mCST): A convenient assessment for treatment effects on prefrontal cognitive function

Table 2 The results of four repeated measures ANOVAs comparing either the accuracy or the duration of performance on either the last vs. the first mCST trial or after vs. before the session break on all experimental days.
