The Joint Position Reproduction test (JPR), one of the most widely used measurements to estimate proprioceptive accuracy, requires the short term storage of proprioceptive information. It has been suggested that visuospatial sketchpad plays a fundamental role in the memorization of proprioceptive information. The current study aimed to investigate this assumption. To do so, we developed and used a novel JPR protocol to measure the retention capacity with respect to sequences of different positions. Our goal was to develop the original task further to make it comparable with other widely used short-term memory measurements, in which the memory capacity was determined by the number of the items participants retain (memory span). We compared participants' (N=39) performance in this task to that of results of Corsi block-tapping task (capacity of the visuospatial sketchpad) and Digit span task (capacity of the phonological loop). Proprioceptive memory capacity did not correlate either with spatial or verbal memory capacity. The exploratory analysis revealed that proprioceptive span correlated positively with the performance if 5 joint positions had to be retained. Further associations with verbal span for 6 or 7 positions, and spatial span for 5 positions were found. Our findings do not support the idea that visuospatial sketchpad plays a fundamental role in the storage of proprioceptive information. The independence of span measures indicates that proprioceptive information might be stored in a subsystem independent of the visuospatial sketchpad or phonological loop.
联合位置再现测试（JPR）是最广泛用于估计本体感受准确性的测量方法之一，需要短期存储本体感受信息。有人认为，视空间工作记忆在本体感受信息的记忆中起着至关重要的作用。本研究旨在验证这一假设。为此，我们开发并使用了一种新的 JPR 协议来测量不同位置序列的保留能力。我们的目标是进一步发展原始任务，使其与其他广泛使用的短期记忆测量方法相媲美，在这些方法中，记忆容量由参与者保留的项目数量决定（记忆广度）。我们将参与者（N=39）在该任务中的表现与 Corsi 积木测试（视空间工作记忆容量）和数字广度测试（语音回路容量）的结果进行了比较。本体感受记忆容量与空间或言语记忆容量均无相关性。探索性分析表明，本体感受广度与需要保留 5 个关节位置时的表现呈正相关。进一步发现，对于 6 或 7 个位置，以及对于 5 个位置，与言语广度和空间广度都存在关联。我们的研究结果不支持视空间工作记忆在本体感受信息存储中起着基本作用的观点。广度测量的独立性表明，本体感受信息可能存储在与视空间工作记忆或语音回路独立的子系统中。
