为1,796名参与者（35-85岁）建立了陈述性记忆的六因素高阶模型（两个二阶因素：情景记忆和语义记忆;四个一阶因素：回忆，识别，流畅性和知识）的性别不变性。跨性别的一阶和二阶因子负荷的度量不变性被证明。在二阶水平，女性的优势，观察到的情节和语义记忆。在一阶水平上，情景记忆的性别差异在回忆和识别方面都很明显，而语义记忆的差异则是由女性在流畅性方面的优势所驱动的。在三个年龄组（35-50岁，55-65岁和70-85岁）的性别差异的额外测试表明，女性在陈述性记忆方面的优势随着年龄的增长而减弱。具体因素的性别差异进行了讨论，在海马功能的性别差异。
Sex invariance of a six-factor, higher order model of declarative memory (two second-order factors: episodic and semantic memory; and four first-order factors: recall, recognition, fluency, and knowledge) was established for 1,796 participants (35-85 years). Metric invariance of first- and second-order factor loadings across sex was demonstrated. At the second-order level, a female advantage was observed for both episodic and semantic memory. At the first-order level, sex differences in episodic memory were apparent for both recall and recognition, whereas the differences in semantic memory were driven by a female superiority in fluency. Additional tests of sex differences in three age groups (35-50, 55-65, and 70-85 years of age) indicated that the female superiority in declarative memory diminished with advancing age. The factor-specific sex differences are discussed in relation to sex differences in hippocampal function.
