Abstract

Although attention deficit/hyperactivity disorder (ADHD) is associated with impairment in working memory and short-term memory, up to half of individual children with ADHD perform within a normative range. Heterogeneity in other ADHD-related mechanisms, which may compensate for or combine with cognitive weaknesses, is a likely explanation. One candidate is the robustness of parasympathetic regulation (as indexed by respiratory sinus arrhythmia; RSA). Theory and data suggest that a common neural network is likely tied to both heart-rate regulation and certain cognitive functions (including aspects of working and short-term memory). Cardiac-derived indices of parasympathetic reactivity were collected during short-term memory (STM) storage and rehearsal tasks from 243 children (116 ADHD, 127 controls). ADHD was associated with lower STM performance, replicating previous work. In addition, RSA reactivity moderated the association between STM and ADHD - both as a category and a dimension - independent of comorbidity. Specifically, conditional effects revealed that high levels of withdrawal interacted with weakened STM but high levels of augmentation moderated a positive association predicting ADHD. Thus, variations in parasympathetic reactivity may help explain neuropsychological heterogeneity in ADHD.

  • Ward et al. (2015) found that children with higher ADHD symptoms showed worse task performance and reduced RSA withdrawal from baseline/rest to the task.

    “Ward et al. (2015) measured short term memory and found that children with higher ADHD symptoms showed worse task performance and reduced RSA withdrawal from baseline/rest to the task, which is a sign of reduced functioning of the PNS when switching from a less-to a more-attentional demanding situations.”

    The Results (Primary Analyses; page not available in our copy) show poorer short-term-memory task performance in children with ADHD. They do not show the claimed reduction in RSA withdrawal: RSA reactivity did not differ significantly between the ADHD and control groups. The Follow-Up Analyses instead report an interaction between memory performance and RSA change in predicting symptom scores, not a general finding that higher symptoms meant reduced withdrawal.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
