Stability, growth, and decline in adult life span development of declarative memory: Cross-sectional and longitudinal data from a population-based study

Rönnlund, Michael, Nyberg, Lars, Bäckman, Lars, Nilsson, Lars-Göran·2005·Psychology and Aging

Abstract

Five-year changes in episodic and semantic memory were examined in a sample of 829 participants (35-80 years). A cohort-matched sample (N=967) was assessed to control for practice effects. For episodic memory, cross-sectional analyses indicated gradual age-related decrements, whereas the longitudinal data revealed no decrements before age 60, even when practice effects were adjusted for. Longitudinally, semantic memory showed minor increments until age 55, with smaller decrements in old age as compared with episodic memory. Cohort differences in educational attainment appear to account for the discrepancies between cross-sectional and longitudinal data. Collectively, the results show that age trajectories for episodic and semantic memory differ and underscore the need to control for cohort and retest effects in cross-sectional and longitudinal studies, respectively.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Historical increases in the quantity of educational attainment during the 20th century are a major factor underlying cognitive cohort differences.

    “Our rationale was that historical increases in the quantity of educational attainment during the 20th century are a major factor underlying cognitive cohort differences (Alwin & McCammon, 2001; Hauser & Huang, 1997; Rönnlund et al., 2005).”
  • Quantitative differences in schooling may underlie cohort differences in intellectual performance.

    “Such quantitative differences in schooling may underlie cohort differences in intellectual performance (e.g., by promoting cognitive reserve; Rönnlund, Nyberg, Bäckman, & Nilsson, 2005; Stern, Albert, Tang, & Tsai, 1999).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
