对102名男性和女性样本进行了一系列的25项生理、能力和个性测试，其中大部分预计会随着年龄的变化而变化，年龄跨度从20岁到70岁不等。用质心法从25×25的相关矩阵中提取了5个因子，并旋转成近似于倾斜简单结构的因子。获得了一个单一的一般老化因素，加载了25个测量中的19个，几乎解释了年龄的所有变化。不可能把这个一般因素分解，也就是说，把它的方差更多地归因于次要因素。我们必须得出结论，在这项分析的层面上，衰老是沿着单一维度发生的，最好的衡量标准是血压、晶状体调节能力和声阈值，而不是能力和速度测试。因素2证明了老化因素的普遍性。因子2是一个明确的一般能力因子，与老化因子近似正交，没有年龄负荷。由于没有超平面，老化因素的定位不准确。进一步的因素分析应该包括超平面中的足够数量的方差，以使老化因素能够旋转到唯一的位置。
A battery of 25 physiological, ability and personality measures, most of which were expected to vary with age, were administered to a sample of 102 males and females evenly covering the age span of 20 to 70 years. Five factors were extracted from the 25 x 25 correlation matrix by the centroid method and rotated into an approximation to oblique simple structure. A single general aging factor was obtained, loading 19 of the 25 measures and accounting for almost all the variance of age. It was not possible to break this general factor down, that is, to unload more of its variance onto the minor factors. We must conclude that, at the level of this analysis, aging occurs along a single dimension, measured best by blood pressure, lens accommodation and sound threshold and less well by ability and speed tests. Factor 2 lent credence to the generality of the aging factor. Factor 2 was an unambiguous general ability factor approximately orthogonal to the aging factor and having no age loading. Because of the lack of a hyper-plane, the positioning of the aging factor was inexact. A further factor analysis should include a sufficient amount of variance in the hyper-plane to enable the rotation of the aging factor to a unique position.
