| Annotation | The authors examined 3.7 year selectivity in the the Berlin Aging Study (BASE) by comparing the T1 parent sample (n=516) with the T3 sample (n= 206). Selectivity was partitioned into a mortality-associated component, reflecting the degree to which individuals still alive at T3 (T3 survivors, n=313) differ from the T1 parent sample from which they originated, and an experimental component, reflecting the degree to which the T3 sample of 206 differs from T3 survivors. Across 40 variables representing medical, sensorimotor, cognitive, personality-related, and socioeconomic domains, the mortality-associated component accounted for 64% of total selectivity, and the experimental component for 36%. Except for age and intelligence, experimental selectivity effects regarding means and prevalence rates were generally small. Partitioning selectivity into mortality-associated and experimental components is a useful tool in the longitudinal study of ageing. (RH). |
