Study was first presented at the annual invitational address to Division 20, Maturity and Old Age, at the meeting of the American Psychological Association, August 30, 1968. (MS)

Explored the interactional effect between victims' (N=30) adult developmental stage and their coping and emotional reactions following a myocardial infarction (MI). The findings point to the usefulness of adult developmental psychology in understanding the divergent emotional and coping reactions of MI patients across the life-cycle. (Author/JAC)

Suggests that a careful review of the logical and empirical bases for the myth argument indicates that there is little to justify it. The evidence suggests that if one lives long enough, decrements in at least some of the important abilities of intelligence is likely to occur. (Author/AM)

This paper presents a study which indicates that accurate performance on a simple conservation task need not be related to congnitive maturity. Twenty adults and 20 third graders were given three verbal problems, each requiring a same-different judgment and an explanation of that judgment. Only 3 adults were able to give correct judgments, while…

Group interaction research typically focusses on behavior under "laboratory" conditions rather than in less contrived situations. Observation of natural group behaviors at different ages can effect a better understanding of their occurrence and patterning at various developmental stages. Knowledge of age-related group behavior tendencies could…

Students of human development increasingly recognize that chronological age is not necessarily the best and certainly not the only measure of an individual's "age." The present study is an examination of the attitudinal correlates of subjective age identification among the younger adults in a nationally representative sample of the United States…

This paper presents a model of cognitive development across the life span that is designed to integrate the diverse empirical evidence in the area of cognitive development in childhood and adulthood. Relevant research is reviewed in the relationships between performance and age, and the effects of training on performance. A model is then proposed…

Based largely on research in adult development and aging, these readings and discussion questions pertain to such aspects of development and adjustment in middle life as the following: individual differences in aging; biological changes through the adult years; changes in the physical senses (vision, hearing, taste, smell, touch, and pain)…

This paper is concerned with adaptation through time and with life time as differentiated from calendar or historical time. Life time is that of socially defined time; thus the author examines the system of social expectations regarding age-appropriate behavior which requires adaptive behavior on the part of adults.

In March 1959, Howard McClusky introduced his Power Load Margin (PLM) theory and proposed that it be used for studying the adult years and for developing and building realistic educational programs for adults. His formula, which states that the key components of adulthood are load (the demands made upon the individual by self and society) and…
