Sluggish Cognitive Tempo and Working Memory Training
Behavioral symptoms such as drowsiness, lethargy, and hypoactivity are characteristics of individuals with sluggish cognitive tempo (SCT), which is associated with dysfunction in attention and executive functioning. Cogmed Working Memory Training® (CWMT) is an internet based, intensive, and systematic training program. The current study examined whether the effectiveness of CWMT differed according to the level of SCT symptoms of youth with attentional and learning difficulties. SCT scores were obtained from 50 youth (31 boys and 19 girls) between the ages of 5 and 14. Pre- and post-neuropsychological assessment included WISC-IV, Conners’ CPT-II, and NEPSY-II subtests of attention and executive functioning, as well as the parent and the teacher ratings of the BRIEF. Weak trends toward significant negative correlations were found between reaction time related attention markers and SCT, and most of the self-report measures of executive functioning were significantly and negatively correlated with SCT. Importantly, for the 19 children who completed CWMT, those with low SCT symptoms showed stronger gains on executive functioning than those with high levels of SCT symptoms. The findings of this study indicate that SCT might play a moderating role in CWMT, which would be a possible reason why there have been mixed results for the benefits of CWMT.
