Abstract

The present study was designed to investigate the hypothesis that children with Attention Deficit Hyperactivity Disorder combined subtype (ADHD-C) have a generalized executive functioning (EF) [Barkley, R. A. (1997). Behavioural inhibition, sustained attention, and executive functions: Constructing a unifying theory of AD/HD. Psychological Bulletin, 121, 65-94; Barkley, R. A. (1997). ADHD and the nature of self-control. New York: The Guilford Press]. We tested whether ADHD-C and ADHD inattentive subtype (ADHD-I) can be differentiated from each other on EF measures. We compared 16 normally developing boys with 16 boys with ADHD-C and 16 with ADHD-I on five EF domains. The boys were all matched on age, IQ, and the presence of oppositional defiant disorder (ODD)/conduct disorder (CD). Despite carefully diagnosed groups and methodological controls, the results do not support the EF-hypothesis of ADHD-C. Children with ADHD-C differed from normal controls (NC) on tasks related to inhibition; they did not exhibit EF deficits on all EF tasks. Children with ADHD-C also exhibited deficits on non-EF tasks. Furthermore, the ADHD-C and ADHD-I subtypes did not differ from one another. Neuropsychological findings on the domains under study did not yield evidence for the distinctiveness of ADHD-C and ADHD-I subtypes.

  • Beyond learning disorders, processing speed deficits are most consistently associated with ADHD in the mental health literature.

    “To date, beyond learning disorders, PS deficits are most consistently associated with attention-deficit/hyperactivity disorder (ADHD) in the mental health literature23–34.”

    From Diagnostic Associations of Processing Speed in a Transdiagnostic, Pediatric Sample (2020) · cites this paper as [28]

    In §3.2.1 (page unavailable), the paper reports no significant difference in mean reaction time—a measure of response-execution speed—between children with either ADHD subtype and controls. It does report slower stop-signal reaction times in §3.1.1, but identifies those as a response-inhibition difficulty, not a processing-speed deficit. The paper also does not make the claimed comparison across mental-health conditions. (LLM, conf=0.76)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • Some research has shown that all three ADHD presentations have similar processing speed deficits, indicating that processing speed is not a differentiating factor within ADHD presentations.

    “Some research has shown that all three presentations have similar PS deficits, indicating that PS is not a differentiating factor within ADHD presentations25–28.”

    From Diagnostic Associations of Processing Speed in a Transdiagnostic, Pediatric Sample (2020) · cites this paper as [28]

    The Discussion reports that ADHD-C and ADHD-I could not be differentiated on most neuropsychological measures. But the study did not include the third presentation, ADHD-H, and its response-execution results (Table 3) show no significant group difference in mean reaction time; it therefore does not establish similar processing-speed deficits across all three presentations. (LLM, conf=0.85)

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.
