Applied Developmental Psychology as an Implementation of the Life-Span View of Human Development

Application of knowledge about psychological development should, ideally, be theory based. As such, these applications represent “natural ontogenetic experiments”; the results of the evaluation of such interventions feed back to the theory, helping to support, falsify, or refine the ideas from the theory which led to the particular application. Such applied developmental intervention research is central within a currently popular perspective of life-span human development. Thus, applied developmental intervention research provides critical tests of such key concepts within this life-span perspective as: plasticity; multidirectionality; the synthesis of continuous and discontinuous processes across ontogeny; contextual embeddedness; and the role of individuals as agents in their own development. This paper elucidates some of the major features of the dynamic linkage between applied developmental psychology and this view of life-span human development. Key elements of this life-span perspective and the facts of developmental intervention, as seen from this perspective, are specified. Finally, the doctoral training program at the authors' institution is presented as one example of how this link may be institutionalized in the form of graduate education.

The Experience of Micro and Macro Events: A Life-Span Analysis

This study investigated how individuals retrospectively construe their lives in terms of major life events. Ninety-nine participants sorted a set of personal and historical events in terms of perceived importance for their lives. Analyses of variance with repeated measures and rank comparisons were computed. Overall findings revealed no cohort differences with regard to the perception of life events. However, within-cohort differences were found, indicating that more life events were recalled from the young adult years. Those experiences were also perceived as having been more important in the participants' lives than events from other age segments. With regard to historical events, war-related experiences were among the highest ranked. Analyses of variance revealed intracohort differences but not intercohort differences, indicating higher scores for the time between 1930 and 1948 relative to other historical periods.
