BrainHQ Learning Rate |
Participants completed a Divided Attention Task during 5 sessions of tDCS. Unit of measure: milliseconds Meaning: lowest threshold reached across trials / fastest reaction time Direction: lower values represent better performance |
Learning rate will be computed over 5 sessions of tDCS spanning 28 to 56 days; Each of the 5 tDCS sessions are 46 minutes long. The divided attention task is administered at the end of each tDCS session. |

Change in D-KEFS Verbal Fluency - Letter |
The Delis-Kaplan Executive Function System (D-KEFS) cognitive battery measures executive functioning skills. Task performance is in scaled score points based on items generated and errors (range of 1-19 with a mean of 10 and a standard deviation of 3). Here, we present difference scores between session 1 (baseline) and 5 (completion). Greater values represent more change. Positive values represent improvement; negative values represent decline in performance. |
D-KEFS will be administered at baseline and at the final visit (28 to 56 days after baseline) |

Delis Rating of Executive Functioning (D-REF) |
The Delis Rating of Executive Functioning (D-REF) contains 60 items rated by the parent to measure the child's executive functioning compared to age-peers. Results are calculated as T-scores, which have a mean of 50 and a standard deviation of 10. Here, we present the scores at study completion (visit 5), post-intervention. Greater values reflect greater executive functioning impairment. |
D-REF will be administered at baseline and at the final visit (28 to 56 days after baseline). NOTE that baseline scores are listed previously in the appropriate section |

Change in Flanker Inhibitory Control and Attention Task |
The Flanker Inhibitory Control and Attention Task from the NIH Toolbox measure inhibitory control and attention. Task performance is in T-scores based on correct items and errors (mean of 50 and a standard deviation of 10). Here, we present difference scores between session 1 (baseline) T-score and 5 (completion) T-score. Greater values represents more change. Positive values represent improvement; negative values represent decline in performance. |
