The Relationship

Measures of memory performance and cognitive and lifestyle variables were obtained from 147 younger twin pairs (27 to 60 years) and 194 older twin pairs (60 to 94 years) as part of the Minnesota Twin Study of Adult Development and Aging. Correlational and behavior genetic analyses were combined to investigate age differences in 1) the relationship between memory performance and cognitive and lifestyle variables, 2) genetic and environmental influences on memory performance, and 3) genetic and environmental mediation of the relationship between memory and predictor variables. No age differences in heritability were found. Qualitative age differences in memory processes were suggested by age group differences in the correlations between memory and cognitive factors. Even though age differences in phenotypic correlations had been demonstrated, no age differences in the genetic and environmental mediation of the correlations were found. In other words, the magnitude of the correlation between memory and cognitive factors varied across age groups but the nature of the relationship did not.

And Gender

Three cross-sectional studies examined stability and change in personality over the course of life by measuring the relations linking age to personality traits, self-efficacy beliefs, values, and well-being in large samples of Italian male and female participants. In each study, relations between personality and age were examined across several age groups ranging from young adulthood to old age. In each study, personality constructs were first examined in terms of mean group differences accrued by age and gender and then in terms of their correlations with age across gender and age groups. Furthermore, personality-age correlations were also calculated, controlling for the demographic effects accrued by marital status, education, and health. Findings strongly indicated that personality functioning does not necessarily decline in the later years of life, and that decline is more pronounced in males than it is in females across several personality dimensions ranging from personality traits, such as emotional stability, to self-efficacy beliefs, such as efficacy in dealing with negative affect. Findings are discussed in terms of their implications for personality theory and social policy.
