Abstract

The one-target advantage (OTA) refers to faster execution of single-target movements compared to the same movement embedded in a two-target reaching sequence. While well documented in younger adults, little is known about OTA in older adults with age-related motor changes. This study examined whether augmented sensory feedback modulates goal-directed aiming during the OTA paradigm. Thirty right-handed participants (15 younger, 15 older adults) performed one- and two-target aiming tasks under vibrotactile (VT), auditory (A), and no-feedback (NF) conditions. Results showed that reaction time was shorter in the two-target task than in the one-target task under VT feedback (p = .002). Older adults demonstrated significantly shorter movement times with VT than with NF. Older adults showed greater undershooting in the two-target task under NF, which was reduced with VT feedback (p = .011). Additionally, older adults typically spent longer in the time after peak velocity, but VT feedback significantly reduced this duration. Overall, VT feedback improved both temporal and spatial measures, particularly for older adults. Auditory feedback showed limited effects, influencing only TAPV1 (p = .036). Together, these results highlight the potential of VT feedback to mitigate age-related motor performance declines.

单一目标优势的年龄相关差异：探索增强感觉反馈的影响。

单目标优势（OTA）是指与嵌入在两个目标到达序列中的相同运动相比，单目标运动的执行速度更快。虽然在年轻人中有充分的文献记载，但对老年人与年龄相关的运动改变的OTA知之甚少。本研究考察了在OTA范式中增强感觉反馈是否调节目标导向瞄准。30名右利手参与者（15名年轻人，15名老年人）在振动触觉（VT），听觉(A)和无反馈（NF）条件下执行一个和两个目标瞄准任务。结果表明，在VT反馈下，双目标任务的反应时间比单目标任务的反应时间短（p = 0.002）。老年人在VT时的运动时间明显短于NF时。老年人在NF下的双目标任务中表现出更大的低射击，而VT反馈则减少了这一现象（p = 0.011）。此外，老年人通常在峰值速度后花费更长的时间，但VT反馈显着缩短了这一持续时间。总的来说，VT反馈改善了时间和空间测量，特别是对于老年人。听觉反馈的影响有限，仅影响TAPV1 （p = 0.036）。总之，这些结果强调了VT反馈在缓解与年龄相关的运动能力下降方面的潜力。

期刊介绍： The Journal of Motor Behavior, a multidisciplinary journal of movement neuroscience, publishes articles that contribute to a basic understanding of motor control. Articles from different disciplinary perspectives and levels of analysis are encouraged, including neurophysiological, biomechanical, electrophysiological, psychological, mathematical and physical, and clinical approaches. Applied studies are acceptable only to the extent that they provide a significant contribution to a basic issue in motor control. Of special interest to the journal are those articles that attempt to bridge insights from different disciplinary perspectives to infer processes underlying motor control. Those approaches may embrace postural, locomotive, and manipulative aspects of motor functions, as well as coordination of speech articulators and eye movements. Articles dealing with analytical techniques and mathematical modeling are welcome.
