评估了成年后感觉和认知功能变化率之间的相关性。在1992年、1994年和2000年，在澳大利亚老龄化纵向研究中获得了视力、听力、记忆力、速度和言语能力的测量结果（基线N = 2，087）。使用潜在生长曲线模型分析了至少进行1次临床评估的1，823名参与者的数据。在对年龄、性别、教育程度、自评健康状况、医疗条件和抑郁症状的影响进行统计学控制后，发现记忆力和视力的变化率之间存在显著的中等程度的相关性。听力的变化率与记忆的变化率弱相关。研究结果支持了一个理论，该理论除了老年感觉和认知变化的共同因素外，还包括独特因素的主要作用。
Correlations among rates of change in sensory and cognitive functioning in adulthood were evaluated. Measures of Vision, Hearing, Memory, Speed and Verbal ability were obtained in 1992, 1994, and 2000 in the Australian Longitudinal Study of Aging (N = 2,087 at baseline). Data from 1,823 participants who undertook at least 1 clinical assessment were analyzed using latent growth curve models. A significant moderate-sized association between rates of change in Memory and Vision was found. This remained after statistically controlling for the effects of age, gender, education, self-rated health, medical conditions, and depressive symptoms. Rate of change in Hearing was weakly associated with rate of change in Memory. The results support a theory incorporating a major role for unique factors in addition to common factors underlying sensory and cognitive change in old age.
