Abstract
Questionnaires like the Metamemory in Adulthood Questionnaire (MIA; Dixon, Hultsch, & Hertzog, 1988) have been used to examine longitudinal changes and cross-sectional age differences in multiple metamemory facets (e.g., memory self-efficacy). This study used 3 independent cross-sectional samples (N = 1,555; ages 55-85) from the Victoria Longitudinal Study collected in 1986, 1992, and 2000 to evaluate period and cohort effects on 8 MIA scales. Alternative general linear models analyzed age, cohort, and period effects, while subsequently assessing gender differences in metamemory beliefs. Period effects were detected on the MIA Internal Strategy and External Strategy scales; self-reported use of internal strategies decreased while use of external memory aids increased over the historical period. Reliable cohort (generational) differences were found for MIA Change, with the lowest levels of perceived change in individuals born between 1916 and 1925. MIA Task, measuring knowledge about memory, produced small age and cohort effects. Gender differences emerged in metamemory, especially for the Internal Strategy and External Strategy scales (women reporting higher strategy use). Gender differences were also seen for the Capacity, Locus, Anxiety, and Achievement scales, with women reporting higher perceived memory efficacy, control, memory anxiety, and greater motivation to have better memory, respectively. The historical trends in metamemory beliefs should be replicated with other measures and other populations; however, the results generally confirm conclusions from earlier cross-sectional studies regarding age sensitivity of metamemory beliefs from middle age to old age.
