Las diferencias individuales en el proceso de envejecimiento humano

Resum

This article reviews the main trends in human aging research during the XX century upto and including the study of differences between individuals in groups, between individuals and intra-individuals. Descriptive data are presented which demonstrate the need to take into account individual differences in the study of the aging process. These variables include sex, age, marital status, and the personality dimensions of extraversion and neuroticism. A comparison is made between the subjective data drawn from self-perceptions recorded via partially structured interviews and objective data, including general psychological and physical health.
