The present study sought to determine if adults with ADHD demonstrate reduced graphomotor learning relative to controls.
Twenty-eight control adults (n=14) and adults with ADHD (n=14) were recruited and wrote a novel grapheme on a digitizing tablet 30 times. Participants with ADHD were counterbalanced on and off stimulant medication.
Control participants, F(1,13)=13.786, p=.003, ω(2)partial=.460, and participants with ADHD on medication, F(1,13)=10.462, p=.007, ω(2)partial=.387, demonstrated significant improvement in graphomotor fluency with equivalent practice whereas participants with ADHD off medication did not, F(1,12)=0.166, NS.
Results indicate that graphomotor program learning in adults with ADHD may occur more slowly than typically developing peers. Findings have implications for providing accommodations to adults with ADHD, potential benefits of stimulant medication, and using digitizing technology as a neuropsychological assessment instrument.
本研究旨在确定患有注意力缺陷多动障碍（ADHD）的成年人与对照组相比，其书写运动学习能力是否降低。
招募了28名对照成年人（n = 14）和患有ADHD的成年人（n = 14），并在数位板上书写一个新的字素30次。患有ADHD的参与者在服用和未服用兴奋剂药物的情况下进行了平衡处理。
对照参与者，F(1,13)=13.786，p =.003，ω(2)偏倚=.460，以及服用药物的ADHD参与者，F(1,13)=10.462，p =.007，ω(2)偏倚=.387，在同等练习下书写运动流畅性有显著提高，而未服用药物的ADHD参与者则没有，F(1,12)=0.166，无显著性差异。
结果表明，患有ADHD的成年人的书写运动程序学习可能比正常发育的同龄人更慢。研究结果对为患有ADHD的成年人提供便利、兴奋剂药物的潜在益处以及将数位技术用作神经心理学评估工具具有启示意义。
