Abstract

BACKGROUND: Theories of attention-deficit/hyperactivity disorder (ADHD) posit either executive deficits and/or alterations in motivational style and reward processing as core to the disorder. Effects of motivational incentives on electrophysiological correlates of inhibitory control and relationships between motivation and stimulant medication have not been explicitly tested. METHODS: Children (9-15 years) with combined-type ADHD (n = 28) and matched typically developing children (CTRL) (n = 28) performed a go/no-go task. Electroencephalogram data were recorded. Amplitude of two event-related potentials, the N2 and P3 (markers of response conflict and attention), were measured. The ADHD children were all stimulant responders tested on and off their usual dose of methylphenidate; CTRLs were never medicated. All children performed the task under three motivational conditions: reward; response cost; and baseline, in which points awarded/deducted for inhibitory performance varied. RESULTS: There were effects of diagnosis (CTRL > ADHD unmedicated), medication (on > off), and motivation (reward and/or response cost > baseline) on N2 and P3 amplitude, although the N2 diagnosis effect did not reach statistical significance (p = .1). Interactions between motivation and diagnosis/medication were nonsignificant (p > .1). CONCLUSIONS: Motivational incentives increased amplitudes of electrophysiological correlates of response conflict and attention in children with ADHD, towards the baseline (low motivation) amplitudes of control subjects. These results suggest that, on these measures, motivational incentives have similar effects in children with ADHD as typically developing CTRLs and have additive effects with stimulant medication, enhancing stimulus salience and allocation of attentional resources during response inhibition.

  • Performance-based incentives and optimal task pace help to offset impaired arousal regulation in ADHD.

    “suggest that these factors help to offset impaired arousal regulation in ADHD.”

    From Is autonomic nervous system function atypical in Attention Deficit Hyperactivity Disorder (ADHD)? A systematic review of the evidence (2020) · cites this paper as Groom et al., 2010

    The Abstract Conclusions and Discussion (Effects of Diagnosis and Motivation; page not provided) report that incentives increased electrophysiological markers of attention and response conflict in children with ADHD, bringing them closer to control-group baseline levels. The Methods (Paradigm; page not provided) describe task timing and an adaptive response-time limit, but do not show that an optimal task pace offsets impaired arousal regulation. That part of the claim is unsupported. (LLM, conf=0.84)

  • This indicates that impaired arousal regulation in ADHD may be malleable by motivational incentives.

    “This indicates that impaired arousal regulation in ADHD may be malleable by motivational incentives, consistent with previous evidence showing the effects of motivational incentives on electrophysiological (Groom et al., 2010(Groom et al., , 2013) ) and fMRI correlates (Liddle et al., 2011) in ADHD.”

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.
