abstract="The impact of three types of everyday activities (i.e., social, experiential, and developmental) on four cognitive functions (i.e., immediate recall, learning, fluid intelligence, and information-processing speed) and one global indicator of cognitive functioning (Mini-Mental State Exam score) over a period of 6 years was studied in a large 55--85 year-old population-based sample (N = 2,076). A cross-lagged regression model with latent variables was applied to each combination of 1 cognitive function and 1 type of activity, resulting in 15 (3 x 5) different models. None of the activities were found to enhance cognitive functioning 6 years later when controlling for age, gender, level of education, and health, as well as for unknown confounding variables. Conversely, one cognitive function (i.e., information-processing speed) appeared to affect developmental activity. It is suggested that no specific activity, but rather socioeconomic status to which activities are closely connected, contributes to maintenance of cognitive functions.<p /><p>Language: en</p>",
