title: The problems of generations: and generational analysis.
abstract: The focus of this paper is two fold: 1. conceptual and methodological problems underlying the life-span sociology literature that heretofore have not been discussed; and 2. application of the generational analysis model to the question of life cycle change in personal values. Specifically, we address the issues of whether (1) value change over the life course is a result of period shifts or individual maturation and (2) differences in values among age strata are a function of cohort experience or individual maturation (aging). Utilizing data from the Detroit Area Studies, four measures of values were constructed. The analyses shows that on only one of the four dependent measures was aging directly implicated in the findings. However, cohort differences and period effects were found to have a significant effect on the distribution of several of the value indices. The data are consistent with Mannheim's observation that older cohorts are affected by social change although the relative degree of observed change is much greater among the young.
