The Automaticity and Mean Stylus Pressure Profile of Handwriting in Adults with ADHD
Bibliographic record
Abstract
ADHD is a neurobiological disorder typically developed and diagnosed in childhood (Faraone et al., 2003). Impaired motor function is commonly observed in individuals with ADHD, but often overlooked (Brossard-Racine et al. 2011; Meyer and Sagvolden, 2006). Deficits in movement accuracy and increased movement variability can have a profound impact on fine motor skills, such as handwriting (Adi-Japha et al., 2007). The purpose of this study was to determine if automaticity during a handwriting task is impaired in adults with ADHD. The results of this study indicated that adults with ADHD do not have reduced automaticity in their handwriting, but do have significantly increased mean stylus pressure was observed while writing. This suggests that individuals with ADHD may have simple, or dystonic, writer's cramp. Further research should be conducted to determine if simple or dystonic writer's cramp occurs in individuals with ADHD. If so, appropriate treatment methods should be determined.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
