一般智力因素或g的概念在心理学中是有争议的。尽管争论在许多层面上都有，但其中最重要的一个涉及到g在一组个体中的识别和测量。如果g实际上可以预测一系列智力表现，那么在一组心理能力测试中发现的因素应该与在另一组不同的能力集合中发现的因素密切相关。我们解决了在何种程度上这一预测是真实的使用三个心理能力电池管理的异质样本的436名成年人。尽管成套测验中使用的特定任务反映了人类智力表现范围的不同概念，但成套测验确定的g因子完全相关（相关系数分别为0.99、0.99和1.00）。这进一步证明了存在更高水平的g因子，并表明其测量不依赖于特定心理能力任务的使用。(C)2004爱思唯尔公司All rights reserved.
The concept of a general intelligence factor or g is controversial in psychology. Although the controversy swirls at many levels, one of the most important involves g's identification and measurement in a group of individuals. If g is actually predictive of a range of intellectual performances, the factor identified in one battery of mental ability tests should be closely related to that identified in another dissimilar aggregation of abilities. We addressed the extent to which this prediction was true using three mental ability batteries administered to a heterogeneous sample of 436 adults. Though the particular tasks used in the batteries reflected varying conceptions of the range of human intellectual performance, the g factors identified by the batteries were completely correlated (correlations were .99, .99, and 1.00). This provides further evidence for the existence of a higher-level g factor and suggests that its measurement is not dependent on the use of specific mental ability tasks. (C) 2004 Elsevier Inc.
