The factorial validity of the Ruff-Light Trail Learning Test (RULIT) was evaluated for its specificity as a test of visuospatial learning and memory. In a sample of 307 normal adults, principal components analyses (PCAs) were calculated on scores from the RULIT and selected neuropsychological tests. The PCAs revealed visuospatial learning and memory components, which included RULIT scores that were empirically distinct from verbal learning and memory components. These results provide support for the RULIT as a measure of visuospatial learning and memory.
对鲁夫-轻轨迹学习测试（RULIT）的因素效度进行了评估，以检验其作为视觉空间学习和记忆测试的特异性。在307名正常成年人的样本中，对RULIT和选定的神经心理学测试的分数进行了主成分分析（PCA）。主成分分析揭示了视觉空间学习和记忆成分，其中包括根据经验与言语学习和记忆成分不同的RULIT分数。这些结果为RULIT作为视觉空间学习和记忆的一种测量方法提供了支持。
