Abstract

Objective: The efficacy of n-back training for children with attention deficit hyperactivity disorder (ADHD) was tested in a randomized controlled trial. Method: 41 children aged 7 to 14 years with ADHD were trained on an n-back task, and their performance was compared with that of an active control group ( n = 39) who were trained on a general knowledge and vocabulary task. Results: The experimental group demonstrated transfer of training to a nontrained n-back task as well as to a measure of inhibitory control. These effects were correlated with the magnitude of training gains. Conclusion: Our results suggest that n-back training may be useful in addressing some of the cognitive and behavioral issues associated with ADHD.

TL;DR

In a randomized controlled trial, children with ADHD who trained on an adaptive visuospatial n-back task showed transfer to an untrained n-back task and to a lab measure of inhibitory control, with effects correlated with training gains. The authors conclude n-back training may help address some cognitive/behavioral issues in ADHD, though effects were small and delayed parent-reported symptom reductions were marginal.

Key findings

  • At immediate posttest, the n-back group outperformed the active control group on a non-trained n-back task (F(1,77) = 11.41, p = 0.001, η²p = 0.13, BF = 29.50) and on inhibitory control measured by the CPT (F(1,77) = 6.48, p = 0.01, η²p = 0.08, BF = 3.73).
  • At 3-month delayed posttest, group differences remained but were less pronounced and did not survive correction for multiple comparisons (non-trained n-back: F(1,54) = 4.56, p = 0.04, η²p = 0.08, BF = 1.74; CPT: F(1,54) = 4.34, p = 0.04, η²p = 0.07, BF = 1.55).
  • Parent-reported ADHD symptoms showed only marginal reduction (F(1,43) = 3.38, p = 0.07, η²p = 0.07, BF = 1.11), and no significant group transfer was found for working memory composite, matrix reasoning, or school-related tasks.
  • Training gain predicted transfer on several measures, including CPT (b = −6.93, p = 0.03, BF = 1.34), parent-reported inattention/hyperactivity (b = −0.26, p = 0.02, BF = 2.58), school tasks (b = 0.14, p = 0.04, BF = 0.26), matrix reasoning at posttest (b = 0.21, p = 0.05, BF = 0.93), and matrix reasoning at delayed posttest (b = 0.36, p = 0.01, BF = 3.90).

Methods

  • Randomized controlled trial: 108 children with ADHD recruited; after exclusions, final sample was 80 children aged 7–14 (mean age 10.14 years, SD 2.02; 25 girls), matched on fluid reasoning, age, gender, and ADHD symptom severity, then randomly assigned to n-back training (n = 41) or active general knowledge/vocabulary control training (n = 39).
  • Training required 20 sessions over about 5 weeks: once daily at home with parent supervision plus one weekly researcher-supervised session; assessments occurred at pretest, immediate posttest, and 3-month delayed posttest.
  • Main analyses used ANCOVA with pretest as covariate, multiple regression to test whether training gain predicted transfer, and Bayesian analyses; outcome measures included an untrained object n-back task, CPT, verbal working memory composite, parent questionnaires (CBCL, BRIEF, CPRS–R:L), Woodcock-Johnson III school tasks, and matrix reasoning.

Limitations

  • Stated by the authors: outcome measures were either lab-based or parent report; lab measures may lack ecological validity, while parent report has ecological validity but may not be fully objective.
  • Stated by the authors: attrition/dropout was an issue—21 participants (20.79%) did not complete training or failed to adhere to the schedule—though this rate was lower than in similar non-ADHD samples, and excluded participants did not vary systematically from included participants.
  • Evident in the text: the sample was small, especially for delayed and parent-report analyses (e.g., delayed CPT/n-back F tests used df = 54; parent ADHD symptom analysis used df = 43), effect sizes were small, and the marginal parent-report finding did not survive multiple-comparison correction.

    “it can be completed at home in the absence of a trained professional and can be easily distributed at minimal cost to families of children who struggle with ADHD.”
    Quote in the paperNot a substantial claim
  • May combine two claims.

    Interpretationreasoning

    The study provides theoretical support for cognitive training and insight into training gain-transfer links.

    “It also offers theoretical support for cognitive training more broadly, and provides insight into the relationship between training gains and transfer.”

  • May combine two claims.

    Study design and conductown data

    Excluded and included participants did not differ systematically, reducing selection-bias concerns.

    “the excluded participants did not vary systematically from the included participants; alleviating concerns regarding selection bias (see Table 2).”

  • The paper relies on this without support.

    The active control training task only minimally engages working memory or controlled attention.

    “This game also had levels and was adaptive, but only minimally implicated working memory or controlled attention.”
  • The paper relies on this without support.

    The n-back task requires active maintenance and updating of items in working memory and inhibition of responses to lures.

    “The n-back task requires both active maintenance and updating of items in working memory as well as deleting items that are further back in a sequence. It also requires inhibiting responses to near target items, or lures.”
  • The paper relies on this without support.

    Inhibitory control is a mechanism underlying self-regulation and cognitive/achievement deficits in children with ADHD.

    “because inhibitory control is purported to be a mechanism underlying self-regulation and cognitive/achievement deficits in children with ADHD”
  • The paper relies on this without support.

    Cognitive training works best when learners are actively engaged and try hard.

    “This approach was guided by our hypothesis that cognitive training is most effective when participants are actively engaged and put effort into doing their best.”

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • There is no consensus on transfer to inhibitory control measures, with some WM training studies reporting benefits and others not.

    “there is no consensus regarding transfer to inhibitory control measures, with some WM training studies reporting training-related benefits59,60,71,72, yet others failing to find evidence of transfer51,73.”

    From Near transfer to an unrelated N-back task mediates the effect of N-back working memory training on matrix reasoning (2022) · cites this paper as [72]

    The citation is attached to the studies said to have failed to find transfer to inhibitory control. In the Discussion (page unavailable), this paper instead reports improved inhibitory control after n-back training in children with ADHD, albeit with small effects. Its background section describes mixed findings from other studies, but its own result is not a failure to find transfer. (LLM, conf=0.86)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured

Statistics recomputed

Every reported test result, recomputed from its test statistic and degrees of freedom. A result shows as not adding up only once an independent check has confirmed it.

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Abstract says both transfer effects tracked training gains, but the n-back effect did not

    Major

    The abstract refers to the non-trained n-back and inhibitory-control effects as correlated with training gains. The discussion states that training gain had no significant relationship with performance on the non-trained object n-back task.

  • Home-training session counts disagree

    Minor

    The procedure first says children were required to train at home for 20 sessions, but its parenthetical breakdown specifies only 16 sessions at home and four supervised sessions.

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-08.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-08.

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.
