在横断面研究中，陈述性记忆和视觉空间能力的性别差异是稳健的。本纵向研究探讨了在10年的时间内是否存在认知的性别差异，以及年龄是否改变了性别差异的大小。对625名非痴呆成年人（最初年龄为35-80岁）进行了情景和语义记忆以及视觉空间能力的评估测试，这些成年人在两次随访时参加了基于人群的Betula研究。在五个年龄组和超过10年的时间里，性别差异是稳定的。女性在情景回忆、面部和言语识别以及语义流畅性方面的表现比男性更高，而男性在任务评估、视觉空间能力方面的表现比女性更好。认知功能的性别差异在10年期间和35至90岁之间是稳定的。
Sex differences in declarative memory and visuospatial ability are robust in cross-sectional studies. The present longitudinal study examined whether sex differences in cognition were present over a 10-year period, and whether age modified the magnitude of sex differences. Tests assessing episodic and semantic memory, and visuospatial ability were administered to 625 nondemented adults (initially aged 35-80 years), participating in the population-based Betula study at two follow-up occasions. There was stability of sex differences across five age groups and over a 10-year period. Women performed at a higher level than men on episodic recall, face and verbal recognition, and semantic fluency, whereas men performed better than women on a task-assessing, visuospatial ability. Sex differences in cognitive functions are stable over a 10-year period and from 35 to 90 years of age.
