Numerous developmental studies assess general cognitive ability, not as the primary variable of interest, but rather as a background variable. Raven's Progressive Matrices is an easy to administer non-verbal test that is widely used to measure general cognitive ability. However, the relatively long administration time (up to 45 min) is still a drawback for developmental studies as it often leaves little time to assess the primary variable of interest. Therefore, we used a machine learning approach - regularized regression in combination with cross-validation - to develop a short 15-item version. We did so for two age groups, namely 9 to 12 years and 13 to 16 years. The short versions predicted the scores on the standard full 60-item versions to a very high degree r = 0.89 (9-12 years) and r = 0.93 (13-16 years). We, therefore, recommend using the short version to measure general cognitive ability as a background variable in developmental studies.
许多发展研究评估一般认知能力，不是作为主要关注的变量，而是作为背景变量。瑞文渐进矩阵是一种易于管理的非言语测试，被广泛用于测量一般认知能力。然而，相对较长的管理时间（长达 45 分钟）对于发展研究来说仍然是一个缺点，因为它往往没有太多时间来评估主要关注的变量。因此，我们使用机器学习方法——正则化回归结合交叉验证——来开发一个简短的 15 项版本。我们针对两个年龄组进行了这样的研究，即 9 至 12 岁和 13 至 16 岁。简短版本对标准的 60 项完整版本的得分预测非常高，r=0.89（9-12 岁）和 r=0.93（13-16 岁）。因此，我们建议在发展研究中使用简短版本作为背景变量来测量一般认知能力。
