ABSTRACT

Sex/gender-related differences in neurocognitive task performance and their neural correlates have long been of substantial research interest. Spets & Slotnick’s robust study joins a growing body of evidence that significant sex/gender differences exist in long term memory and neurocognition more broadly. In addition to fundamental differences in the neural substrate, hormonal cycles, divergent neurodevelopmental trajectories, sex versus gender identification and sociocultural and educational influences are likely important factors. Building upon these findings, future studies in larger sample sizes should carefully measure these potential modulating and/or confounding variables in order to provide a nuanced picture of sex/gender-related differences in brain function.

摘要

神经认知任务表现的性别/性别相关差异及其神经相关性长期以来一直是重要的研究兴趣。Spets & Slotnick 强有力的研究加入了越来越多的证据，表明更广泛的长期记忆和神经认知存在显着的性别/性别差异。除了神经基质的根本差异外，荷尔蒙周期、不同的神经发育轨迹、性别与性别认同以及社会文化和教育影响可能都是重要的因素。基于这些发现，未来更大样本量的研究应该仔细测量这些潜在的调节和/或混杂变量，以提供大脑功能中性别/性别相关差异的细微差别。
