This research details the changing ways in which young people of different ages differently warrant the conviction that, notwithstanding evidence of good and bad behaviours, selves can be understood as unified across the various roles and contexts that they occupy. Canadian adolescents and young adults were asked to explain the apparent disunity…

Subjects ranged from 60 to 90 years old. (MS)

A review of literature on Piagetian cognitive functioning generally noted lower levels of functioning for elderly subjects than for comparison groups of adults. Several possible interpretations for these age differences were offered. The effects of certain demographic variables on performance were also reviewed and inconsistent results were noted.…

This translation of an article by Vygotsky traces the major theories of periodization and evaluates these views of child development. In addition, he advances his theory of periodization that is based upon the development of the child's personality. (ST)

Explores strategies frequently utilized in developmental research laboratories and discusses the power of these strategies in isolating the major variables whose effects are age (or time)-related. The paper also provides information about the key developmental antecedents of age differences. (Author/WY)

Explores implications of two cognitive development perspectives for characterizing ontogeny of causal reasoning. Reviews literature on causal reasoning in the preschool years and concludes that the hypothesis of an invariant causal scheme is only partially correct. (Author/SO)

Desirability judgments (values) of 4 personality dimensions (affiliation, autonomy, achievement, nurturance) and 2 control scales were investigated in a total of 120 male and female subjects from 4 different age groups representing childhood, adolescence, adulthood, and old age. Clear age and sex differences reflected multiple value systems.…

Three age groups were read the same short story. Their responses to interpretive questions were taken as texts and analyzed for age-distinctive word usage. Characteristic forms of talk were found, and age-specific patterns of interpretive thinking were derived from the forms. In general, 10 year olds saw a plot, adolescents a plight, and adults a…

Comments on the study reported by Feldman and others in this issue. Suggests that, in the study, subjects' word frequencies might be the result of subjects' familiarity with the words rather than the words' narrative role and that there is uncertainty in inferring interpretive patterns of subjects from word frequencies.

Anxiety ratings were analyzed for 858 Israeli children. Lower socioeconomic level children were rated significantly more anxious than higher socioeconomic level children, and girls were higher than boys on both anxiety and lie scales. Results were discussed in terms of child rearing patterns, teacher expectations, and characteristics of the…

Replies to the commentary by Olson and Salter on an article by Feldman and others, both reported in this issue. Maintains that the evidence does not support Olson's and Salter's conjecture that the source of age-distinctive lexical differences reported in the Feldman study is a simple function of word frequency.

The classification behavior of male and female college students was compared with that of healthy, well-educated older males and females. On the whole, the results failed to confirm other published evidence maintaining that aging is marked by conceptual deficits or a regressed mode of cognitive functioning. (Author/CS)

A broad literature review revealed that younger children are more likely to categorize objects along complimentary dimensions than older children who tend to categorize according to similarity. This developmental change is discussed in terms of etiology--internal organismic changes or environmental changes. (DP)

Describes the use of simulated time sequences in the analysis of age-related and socio-historical changes in developmental research. (BD)
