The generality of ability factor structure in adulthood and old age was investigated. Data were analyzed for 198 young individuals (15-32 years), 156 younger old individuals (53-68 years), and 156 older old individuals (69-91). Variables were nine tests marking three ability factors. (Author/CTM)

In-depth interviews were used to investigate how life is experienced by persons at age 85 (N=129) and again at 92 (N=41).

A study selectively examined factors that have contributed to observed limitations of congruent data describing normative, developmental change in adult cognition. A preteritive design was used first to examine limiting factors, and secondly, to examine research strategies that could be used to provide necessary reforms of the data. Three factors…
