本研究的主要目的是建立在正常和同质人群中不同心理和神经心理测试分数之间存在的相互关系。第二个目的是进一步尝试通过神经心理学测试对认知活动进行成分分析。一套全面的神经心理学测试系统被组装起来，并单独对300名年龄在17-25岁之间的受试者进行了测试。他们都是右撇子的男性大学生。这套测试包括一些基本的神经心理学测试，旨在评估语言、计算能力、空间认知、实践能力、记忆、感知能力和执行功能。此外，采用韦氏成人智力量表。计算了41个不同的分数。分析不同测试成绩之间的相关性。研究发现，一些测试呈现出相当复杂的相互关系系统，而另一些测试呈现出很少或没有显著相关性。数学能力测试和拼写知识是全面智商的最佳预测指标。变量旋转因子分析揭示了五个因素（言语、视觉、执行功能、精细运动和记忆）占总方差的63.6%。这些结果对大脑认知组织的神经心理学模型的意义进行了分析。
The main purpose of this research was to establish the intercorrelations existing among different psychological and neuropsychological test scores in a normal and homogenous population. A second purpose was to attempt further step in the component analysis of cognitive activity measured by means of neuropsychological tests. A comprehensive neuropsychological test battery was assembled and individually administered to a 300-subject sample, aged 17-25 years-old. All of them were right-handed male university students. The battery included some basic neuropsychological tests directed to assess language, calculation abilities, spatial cognition, praxic abilities, memory, perceptual abilities, and executive functions. In addition, the Wechsler Adult Intelligence Scale was administered. Forty-one different scores were calculated. Correlations among the different test scores were analyzed. It was found that some of the tests presented a quite complex intecorrelation system, whereas other tests presented few or no significant correlations. Mathematical ability tests and orthography knowledge represented the best predictors of Full Scale IQ. A factor analysis with varimax rotation disclosed five factors (verbal, visuoperceptual, executive function, fine movements, and memory) accounting for 63.6% of the total variance. Implications of these results for a neuropsychological model about brain organization of cognition were analyzed.
