Study arms

  • Experimental
    Arithmetic strategy training

    Participants complete 6 weeks of activities, 1-hour hybrid sessions daily for 3 days per week (in total 18 sessions), that progressively develop the efficient use of arithmetic problem-solving strategies. Before and after training, participants complete arithmetic problem-solving tasks during neuroimaging sessions.

    Behavioral: Arithmetic strategy training

  • Active comparator
    Speeded practice training

    Participants complete 6 weeks of activities, 1-hour hybrid sessions daily for 3 days per week (in total 18 sessions), that focus solely on enhancing arithmetic fluency. Before and after training, participants complete arithmetic problem-solving tasks during neuroimaging sessions.

    Behavioral: Speeded practice training

Interventions

  • BehavioralSpeeded practice training

    Speeded practice training includes activities that focus solely on enhancing arithmetic fluency.

What researchers measure

Primary outcomes

  1. Change from baseline in arithmetic task performance (reaction time)

    Performance will be measured by children's reaction time (milliseconds) on arithmetic task

    Time frame: Baseline and post-intervention (after 6 weeks)

  2. Change from baseline in arithmetic task performance (accuracy)

    Performance will be measured by children's accuracy (% trials correct) on arithmetic task

    Time frame: Baseline and post-intervention (after 6 weeks)

  3. Change from baseline in latent cognitive measures of arithmetic task performance (drift rate)

    Latent cognitive processing will be measured by drift rate from children's arithmetic task performance

    Time frame: Baseline and post-intervention (after 6 weeks)

  4. Change from baseline in latent cognitive measures of arithmetic performance (post-error adjustment)

    Latent cognitive processing will be measured by post-error adjustment from children's arithmetic task performance

    Time frame: Baseline and post-intervention (after 6 weeks)

  5. Change from baseline in brain activation during arithmetic task performance

    Neural activity will be measured during a functional magnetic resonance imaging arithmetic task. Data will consist of beta values from individual-subject contrast maps for the Small vs. Large contrast in the whole-brain general linear modeling functional magnetic resonance imaging analysis.

    Time frame: Baseline and post-intervention (after 6 weeks)

  6. Change from baseline in brain representation during arithmetic task performance

    Neural activity will be measured during the functional magnetic resonance imaging arithmetic task. Data will consist of spatial correlations of voxel-wise brain activation between Trained vs. Rest and Untrained vs. Rest contrasts for individual subjects.

    Time frame: Baseline and post-intervention (after 6 weeks)

  7. Change from baseline in brain connectivity during arithmetic task performance

    Neural activity will be measured during the functional magnetic resonance imaging arithmetic task. Data will consist of generalized psychophysiological interaction beta values from individual subject contrast maps for Small vs. Large contrast.

    Time frame: Baseline and post-intervention (after 6 weeks)

Secondary outcomes

  1. Change from baseline in untrained arithmetic task performance (reaction time)

    Performance will be measured by children's reaction time (milliseconds) on untrained arithmetic task

    Time frame: Baseline and post-intervention (after 6 weeks)

  2. Change from baseline in untrained arithmetic task performance (accuracy)

    Performance will be measured by children's accuracy (% trials correct) on untrained arithmetic task

    Time frame: Baseline and post-intervention (after 6 weeks)

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Sep 2026; primary completion for Sep 2031, 60 months later.

Of 96 non-industry interventional studies with no phase under Learning Disabilities, half reached primary completion within 30 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 53. This study's planned 60 months is above that.

Counting every sponsor, half of 99 studies reached it within 29 months; a quarter within 9 and three quarters within 51.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 24, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
