Subclaims¶

q3 i? ADHD-rs scores were positively correlated with total items produced and with the number of different animals named in a semantic fluency task. → Van den Driessche 2019 q3 i? ADHD score also positively predicted immediate repetitions, controlling for the number of items produced. → Van den Driessche 2019 (2)

Evidence¶

Van den Driessche 2019¶

Van den Driessche, C., Chevrier, F., Cleeremans, A. & Sackur, J. (2019). Lower Attentional Skills predict increased exploratory foraging patterns. Scientific Reports 9:10948. https://doi.org/10.1038/s41598-019-46761-0

q3 · i? · associational · r1

Poisson regressions on semantic fluency (animal naming, 2 minutes) from the same 87-child study: ADHD score predicted total production (β = 0.005, z = 3.477, p < 0.001) and number of different animals (β = 0.004, z = 2.49, p < 0.02); unstandardised coefficients only, so no effect size is coded.

"Scores on the ADHD-rs were positively correlated with higher production (total number of items–β = 0.005, SD = 0.001, z = 3.477, p < 0.001, Poisson regression for count data), but also with higher performance (number of different animals–β = 0.004, SD = 0.0016, z = 2.49, p < 0.02)"

Van den Driessche 2019 (2)¶

Van den Driessche, C., Chevrier, F., Cleeremans, A. & Sackur, J. (2019). Lower Attentional Skills predict increased exploratory foraging patterns. Scientific Reports 9:10948. https://doi.org/10.1038/s41598-019-46761-0

q3 · i? · associational · r2

Poisson regression on counts of immediate repetitions with ADHD score and performance as predictors; both effects positive and significant, meaning "the increased number of repetitions is present even while controlling for number of items produced". There was no effect on distant repetitions (p > 0.2).

"we found significant and positive effects of both the ADHD score (β = 0.017, SD = 0.007, z = 2.33, p = 0.02, see Fig. 2B) and performance (β = 0.049, SD = 0.012, z = 4.006, p < 0.001)"
