A review of research shows that while some studies support (1) the necessity of developing logical (operational) thought, (2) the maintenance of this cognitive level, and (3) the finality of the formal operational stage, the bulk of research challenges these three aspects of traditional Piagetian theory.

In this study of peer instructors in three Learning in Retirement Programs, the constructivist elements embedded in Mezirow's theory of transformational learning are examined at the theoretical intersections of transformational learning and developmental constructivism, specifically the work of Robert Kegan, resulting in a suggested developmental…

A review is presented of major theories on the characteristics of adult cognition. The roles of social and cultural backgrounds, education, mental ability, and experience as they pertain to cognition are discussed. (JD)

While Jean Piaget's work as it relates to the development of childhood and adolescent cognition has long been explored, only recently has the usefulness of Piaget's theory in the study of adult cognition been studied. Recent research by educational psychologists has raised serious doubts about Piaget's theoretical position that the highest level…

Participants aged 17-26, 39-51 and 59-76 solved concept problems to investigate intellectual correlates of concept identification as a function of stage of learning in adulthood. Differential ability-performance relations as a function of stage of learning were considerably less potent in the elderly v the young and middle aged. (Author)

Three types of lay theories about the social world form a developmental sequence. Earlier developing theories are reorganized at the next level into a more inclusive, encompassing view of the world in order to make better predictions. The absolute thinker sees the world as fixed and unchanging, reasons with absolute rules, and has a narrow world…

In order to capitalize on the learning experience which adults bring to the classroom, it is necessary to identify some of the components of the self-initiated learning cycle. A study of 12 adult graduate students' learning experiences in an adult learning class was used to identify a common pattern of experience. The pattern of the learning…

A study selectively examined factors that have contributed to observed limitations of congruent data describing normative, developmental change in adult cognition. A preteritive design was used first to examine limiting factors, and secondly, to examine research strategies that could be used to provide necessary reforms of the data. Three factors…

Computational models of infant categorization often fail to elaborate the transitional mechanisms that allow infants to achieve adult performance. In this article, we apply a successful connectionist model of adult category learning to developmental data. The Supervised and Unsupervised Stratified Adaptive Incremental Network (SUSTAIN) model is…

This textbook is designed to introduce undergraduates to the scientific study of aging in adults. Among the topics covered in the book's 15 chapters are: approaches to the study of adult development and aging (research methodology and related issues, a life-span perspective, ethical issues); theories in the study of adult development (models of…
