Planning for the future and developing a personalized identity are conceived of as important developmental tasks that adolescents and emerging adults are confronted with on the pathway to adulthood. The present study set out to examine whether both tasks develop in tandem by using a short-term longitudinal dataset consisting of 371 college…

Using a symbolic object such as a model as a source of information about something else requires some appreciation of the relation between the symbol and what it represents. Representational insight has been proposed as essential to success in a symbolic retrieval task in which children must use information from a hiding event in a scale model to…

Notes that the Piagetian perspective admits the existence of interindividual differences but interprets them as noise masking the universal logical succession of structures, whereas the differential perspective views development as consisting of "vicarious processes." Asserts that the main aim of the "procedural studies"…

This "classic" article (1972) in the field of deaf studies includes some interpretive notes for current readers. The article examines the effect of deafness on basic developmental tasks at each of the eight developmental stages of Erik Erikson's theory of psychosocial development and explains the more successful passage through these…

Two experiments used a formal model of developmental discontinuity derived from catastrophe theory to test whether the transition from Rule I to Rule II on the balance scale task proceeds discontinuously from ages 6 to 10, focusing on five catastrophe flags. Found that bimodality, inaccessible region, hysteresis, and sudden jump were clearly…

Identifies the common elements from three popular adult development theories (Gould, Levinson et al., and Sheehy). Synthesizes these elements into a framework for describing development during the young adult years. Defines the concept of developmental transition. Discusses the implications of a composite adult development framework for helping…

Presents a developmental model of counselor supervision that conceptualizes the training process as a sequence of identifiable stages through which the trainee progresses. Characteristics of supervisees at each of the four levels are discussed as well as appropriate supervision environments that encourage development to the next highest level.…

Discusses hierarchical complexity of tasks as a way of conceptualizing information in terms of the power required to complete a task, and its implications for developmental psychology and information science. Provides an analytic solution to the definition of developmental stages and allows for the possibility within the science of scaling the…

The purpose of this paper is to review and synthesize the literature on adult development and to suggest how this information can be applied to the practice of adult education. The first section discusses the nature of adult development, its definition, and key concepts. Sequential patterns of change in adulthood are examined in section 2,…

This paper presents how the medico-hygienist model of childhood, which had prevailed throughout the nineteenth century, was replaced at the turn of the twentieth century by the novel developmental model, which arose in the first decades of the 1900s and was later systematised by Piaget, Spock, etc. The medico-hygienist model revolved around core…

Research and theoretical literature about adult development and adult learning are synthesized within a conceptual framework that has three basic domains: life phase, developmental stage, and learning style. The life phase includes theories that identify age-linked periods of stability and transition throughout adulthood. The development stage…

One of the new dimensions of vocational and career counseling is the recognition of the continuity in careers. Despite periods of unemployment and despite a radical change of occupations, the person having these experiences of change is still the same person. Although a career involves the life pursuits of a person, there are several differing…

Piaget's model of children's conceptual learning and development was compared with Klausmeier's Conceptual Learning and Development (CLD) model in a longitudinal study. The CLD model suggests four successive levels of concept learning: (1) concrete--recognizing an object which has been encountered previously; (2) identity--recognizing a known…

The Conceptual Learning and Development (CLD) Model specifies four levels of concept attainment (concrete, identity, classificatory, and formal) and three uses of concepts (problem solving, subordinate-supraordinate, and principles). Longitudinal and cross-sectional studies of concept attainment may be conducted. The results of this study of 300…

Guided by a conceptual model linking discrepancies between parent and adolescent developmental expectations and adolescent adjustment and the quality of the parent-adolescent relationship, this study examined adolescent and parent beliefs about the age at which specific competencies should appear. Developmental timetables were grouped into…
