Previous research suggested that persons with Down syndrome (DS) used a different strategy to drum than typical adults.
The present study examined continuous bimanual drumming strategies in response to different instructions in 10 persons with DS, 10 mental age-matched and 10 chronological age-matched groups. The drumming task required participants to hit two drums with the drumsticks at the same time following verbal (e.g. 'up' and 'down'), visual (e.g. video of both drumsticks moving up and down together) or auditory (e.g. sound of both drums being hit, then cymbal being hit) instructions for 10 s. Sensors placed on the wrists of each participant and the end of each drumstick provided data that allowed the assessment of individual drumming strategies.
In general, when persons with DS were following the visual instructions their drumming movements were shorter, straighter and less variable as compared with their movements in the auditory and verbal conditions.
Whether movement paths were straight or curved, the strategy was to move the drumstick and wrist together as one unit.
先前的研究表明,唐氏综合征(DS)患者击鼓的策略与典型成年人不同。
本研究考察了10名唐氏综合征患者、10名心理年龄匹配者和10名实际年龄匹配者在不同指令下的连续双手击鼓策略。击鼓任务要求参与者按照言语指令(如“上”和“下”)、视觉指令(如两根鼓槌一起上下移动的视频)或听觉指令(如两声击鼓,然后一声钹击),用鼓槌同时击打两个鼓,持续10秒。放置在每个参与者手腕和每根鼓槌末端的传感器提供了数据,以便评估个体的击鼓策略。
总体而言,与听觉和言语条件下的动作相比,唐氏综合征患者在遵循视觉指令时,击鼓动作更短、更直且变化更小。
无论动作路径是直是弯,策略都是将鼓槌和手腕作为一个整体一起移动。
