Short-term memory (STM) challenges are often observed in children with Down syndrome (DS), but existing early STM measures introduce measurement confounds in this population. To address the need for valid early STM measures for future DS interventions, this study evaluated the psychometric properties of a modified Corsi Span task, administered to 110 children with DS. Results indicated that the modified Corsi task has feasibility in the age range of 5-8 years and is scalable across chronological and mental ages. Minimal practice effects and evidence of test-retest reliability and convergent validity were observed. Implications for using a modified Corsi task in studies of early STM and treatment trials for children with DS are discussed.
唐氏综合征（DS）患儿经常出现短期记忆（STM）方面的问题，但现有的早期STM测量方法在这一人群中存在测量混淆。为满足未来DS干预对有效早期STM测量方法的需求，本研究评估了一种改良的科西广度任务的心理测量特性，该任务应用于110名DS患儿。结果表明，改良的科西任务在5至8岁年龄范围内具有可行性，并且在实际年龄和心理年龄上都具有可扩展性。观察到最小的练习效应以及重测信度和收敛效度的证据。本文讨论了在DS患儿早期STM研究和治疗试验中使用改良科西任务的意义。
