我们以 112 名 60-75 岁健康成年人为样本，研究了正常衰老对视觉认知的影响。测试电池旨在捕获视觉工作记忆的高级测量值和视觉空间注意力和记忆的低级测量值。为了回答认知老化如何影响视觉处理能力的特定方面的问题，我们在结构方程模型（SEM；模型 2）中使用了验证性因素分析，并通过 SEM 中的路径分析建模的功能结构（模型 1）提供信息。结果表明，与视觉短期记忆 (VSTM) 能力相比，衰老效应对视觉处理速度的测量具有选择性（模型 2）。这些结果与一些报告选择性老化对处理速度的影响的研究一致，但与报告老化对处理速度和 VSTM 容量的影响的其他研究不一致。在讨论中，我们认为这种差异可能是由年龄范围的差异和人口统计学变量造成的。该研究表明，即使在狭窄的年龄范围内，SEM 也是一种检测认知衰老影响的敏感方法，也是构建测量变量与其所代表的认知功能基础之间关系的有用方法。
We examined the effects of normal aging on visual cognition in a sample of 112 healthy adults aged 60–75. A testbattery was designed to capture high-level measures of visual working memory and low-level measures of visuospatial attention and memory. To answer questions of how cognitive aging affects specific aspects of visual processing capacity, we used confirmatory factor analyses in Structural Equation Modeling (SEM; Model 2), informed by functional structures that were modeled with path analyses in SEM (Model 1). The results show that aging effects were selective to measures of visual processing speed compared to visual short-term memory (VSTM) capacity (Model 2). These results are consistent with some studies reporting selective aging effects on processing speed, and inconsistent with other studies reporting aging effects on both processing speed and VSTM capacity. In the discussion we argue that this discrepancy may be mediated by differences in age ranges, and variables of demography. The study demonstrates that SEM is a sensitive method to detect cognitive aging effects even within a narrow age-range, and a useful approach to structure the relationships between measured variables, and the cognitive functional foundation they supposedly represent.
