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…

Determined nonbiological characteristics that discriminated between age groups and hypothesized life stages for these groups (provisional adulthood, age 30 transition, and settling down). Life stages do not fit completely but were of some use in describing the age groups, particularly provisional adulthood and settling down. (Author/BEF)

Reviews research on children's ability to remember events in relation to that of adults. Concludes that age interacts with other factors, including language and the relative development of knowledge structures, to determine suggestibility. Suggests that children's memories may at times be less easily influenced than adults' memories. (KH)

Examines a variety of personal qualities usually found in creative people. Discusses many theories of creativity representing a variety of intellectual traditions, most of which predict aging decrements of some sort. Suggests that the creativity decline may vary, or that creativity may change rather than decline with age, with differing stylistic…

The ways in which infants, toddlers, children, and adolescents learn social behaviors, through role models, social rules, and rewards and punishment, are described. A four-step social skills training program for preschoolers is discussed. A list of resource materials is provided. (JL)

Visual preference procedures were used to investigate development of perceptually based subordinate-level categorization in 3- to 7-month-old infants. Experiments 1 and 2 demonstrated that 3- to 4-month-olds did not form category representations for photographic exemplars of subordinate-level classes of cats and dogs (i.e., Siamese vs. Tabby,…

This research explored the development of one insight about the mind, namely, the belief that people's trains of thought differ even when they see the same stimulus. In Study 1, 5-year-olds, 9-year-olds, and adults heard stories about characters who saw the same object. Although the older groups predicted the object would trigger different trains…

Proposes developmental approach to smoking education and prevention for children and adolescents. Reviews literature concerning most appropriate agent, content, and presentation of antismoking education for different ages, concluding that best agents for young children are parents and best agents for pre/early adolescents are peers. For…

The Baltimore Longitudinal Study of Aging (BLSA) was begun in 1958 to trace the effects of aging in humans and to distinguish between the true effects of aging and those processes, including disease, socioeconomic disadvantage, and lack of educational opportunity, that may appear or become more pronounced with time but are biologically irrelevant…

Advocates extra time between kindergarten and the first grade for academically and socially immature children to acquire learning skills and develop positive self-esteem. Includes three case studies of former transitional class students. (PKP)

Reviews literature on hemispheric specialization. Argues that foundations of hemispheric specialization are present very early in life and that children's greater ability to recover functions following brain injury suggests developmental changes in brain organization. (CMG)

We investigated how different psychophysical procedures affect frequency discrimination performance in children. Four studies used a design in which listeners heard two tone pairs and had to identify whether the first or second pair contained a higher frequency target tone. Thresholds for 6-and 7-year-olds were higher than those for 8- and…

Notes that subdividing the age group 65 and over into finer age groups unmasks race differentials in mortality and morbidity that often favor blacks in the older age groups. Describes the unusual phenomena; proposes systematic research program to explain them; and discusses existing data sets for their analysis. (Author/NB)

Understanding how children think about the needs of animals may aid bridging from how they care about individual animals to caring about the environment more generally. This study explored changes with age in children's conceptions of animals' needs, including how such conceptions may extend beyond the individual animal to larger systems and…

Developed a multivariate, causal model of the influences of childbearing and early child rearing, to investigate the impact of teenage mothers upon their children. Data analysis indicated socioeconomic status was the strongest influence upon each variable. Found the influence of maternal age in the opposite direction to socioeconomic status.…
