Standardized scores were used for analysis.
We reported subtests that comprised Bonferroni-corrected significant composite scores as described in Table 4.
p-Value ≤ .05.
Bonferroni-corrected p-values ≤ .01.
As raw scores for errors/incorrect responses/reaction time decreased, scaled scores increased.
For clarity, we are referring to the CNS-VS, Four-Part CPT, as Working Memory since only the subtest score which measured Working Memory specifically, comprised the Working Memory domain.
