Models of intelligence in late life: Comment on Hultsch et al

Article Abstract:

Hultsch, Hertzog, Small and Dixon's report of the Victoria Longitudinal Study concluded that there is no significant evidence for major, positive effects of an engaged lifestyle on cognitive change in old age. The differences between the VLS and the Veterans Study are discussed, and the data reanalysis by Hultsch and colleagues is examined to determine if it gives a more meaningful fit for the Veterans Study data than the original model. It is concluded that the original model gives a better explanation of the Veterans Study data.

Structural equation model of intellectual change and continuity and predictors of intelligence in older men

Article Abstract:

Factors that affect the continuity and change of adult cognitive skills are analyzed. A structural equation model was developed to better examine the influence of such factors in later life. Subjects were 326 Canadian army veterans. Results showed relative stability of intellectual scores across 40 years with improvement in vocabulary and regression in arithmetic, verbal analogies and nonverbal skills. Young adult intelligence significantly determined older adult performance.

Everyday activity parameters and competence in older adults

Article Abstract:

A study was conducted to analyze the gauge of everyday activities in connection to cognitive, social and emotional competence. The parameters cover frequency, importance, difficulty, intentions for future activities, changes in past activities and the ability of performance. Results indicate that competence variables helped explain activity parameters independently of age and demographic values.
