The associations between IQ and individual tests of neurocognitive function are well studied. However, there is a lack of information as to how IQ relates to performance on neuropsychological test batteries as a whole and in the same individuals. In this study, 250 healthy participants aged 20-69 years were tested with the Wechsler Abbreviated Scale of Intelligence (WASI) and the MATRICS Consensus Cognitive Battery (MCCB). In correlation analyses, IQ was significantly related to all MCCB scores, except the Social Cognition domain. Hierarchical regression analyses including gender, age, and education confirmed this association. For overall cognitive function, 50% of the variance was explained by IQ and demographic characteristics. For the domains Speed of Processing, Working Memory, Visual and Verbal Learning, IQ explained a larger proportion of the variance than the demographic factors did. The implication is that these domains may provide information of a person's intelligence level.
智商与神经认知功能的各项测试之间的关联已得到充分研究。然而，关于智商如何与整体神经心理测试组合以及同一受试者的测试表现相关，目前仍缺乏相关信息。在本研究中，对250名年龄在20至69岁之间的健康受试者进行了韦氏简易智力量表（WASI）和MATRICS共识认知成套测验（MCCB）测试。在相关性分析中，智商与除社会认知领域外的所有MCCB分数均显著相关。纳入性别、年龄和教育程度的分层回归分析证实了这种关联。对于整体认知功能，50%的方差可由智商和人口统计学特征解释。对于加工速度、工作记忆、视觉和言语学习等领域，智商对方差的解释比例高于人口统计学因素。这意味着这些领域可能提供有关一个人智力水平的信息。
