Baxter Magolda's model emphasizes the importance of the patterns of knowing used by students, and how important those patterns are to the creation of learning environments that empower students both in and out of the classroom. This model can help student affairs educators create these kinds of learning environments. (Author/MKA)

Examined loneliness and friendship among 22 high-functioning children with autism and 19 typically developing children equated for IQ, chronological age, gender, mother's education, and ethnic group. Found that children with autism were lonelier than typically developing children, had less complete understanding of loneliness, and had poorer…

Five adolescents with autism, 5 control participants, and 4 child controls received rewards for varying their sequences of responses while playing a computer game. In preceding and following phases, rewards were provided at approximately the same rate but were independent of variability. When reinforced, variability increased significantly in all…

Argues that the conceptual and methodological foundations of both developmental and difference approaches to mental retardation are deficient. Analysis of the relationship between cognitive functioning and cognitive level within chronological age cohorts allows for more sensitive tests and suggests the need for a paradigm shift based on regression…

The implications of three concepts from cognitive science for understanding of cognitive development are reviewed. These are (1) learning (and induction), (2) analogy, and (3) capacity. A model of analogical reasoning is discussed that specifies changes in representations over age that explain phenomena previously thought to be stage-related. (SLD)

Thirteen 4-year olds were asked to arrange dolls in order from largest to smallest. Longitudinal observations over six months revealed five approaches to ordering and four approaches to correction. The "method of extremum" was employed later in development; otherwise, the order in which approaches appeared was highly variable, with many…

Studied 2-year olds' understanding of pretense expressions of independent agency in scenarios in which a doll acted as the agent of a series of pretend events. Found no gender differences in the doll's imaginary intentions, but older toddlers performed reliably better than younger. Episodes requiring enacting conclusions to events that began with…

Four experiments assessed infants' ability to solve isomorphic problems and explored the nature of early representations. Found that 13-month-olds transferred a modeled strategy across isomorphic problems, whereas 10-month-olds transferred only after multiple source problems or high perceptual similarity between problems. Comprehension of the…

Examines the effects of mothers' strategies of combining employment and welfare receipt during the first three years of their child's life on the child's cognitive development, behavior problems, and home learning environment at ages five and six. No negative association was found on most child outcomes with a mother's employment whether or not it…

Examined in 4 experiments 2-year-olds' knowledge of solidity in search tasks. Found no evidence that 2-year-olds represented solidity and support constraints on trajectories of falling objects; two experiments included 2.5-year-olds who succeeded on search tasks. Explored implications of 2-year-olds' poor performance in light of very young…

Reflects on Needham's findings on infants' object recognition and segregation. Examines the role for perceptual bias in explaining infant performance, places Needham's studies in historical perspective, and assesses their theoretical significance. Discusses the merits of positing different kinds of information sources for object segregation, and…

Examined how 6- to 9-year-olds and adults judged expected value of complex gambles in which alternative outcomes had different prizes. Found that participants at all ages used multiplication rule for integrating probability and value of each individual outcome, and based judgment of overall expected value on alternative outcomes. Even youngest…

Three studies examined lexical categorization in 2-year- olds. Findings indicated that even with minimal opportunities to familiarize themselves with novel artifacts, children generalized their names in accordance with the objects' functions, even when they had to discover the functions on their own or when all the test objects had some…

Three experiments assessed children's abilities to track behavioral, representational, and truth aspects of conventions. Three- and 4-year-olds recognized that conventional stipulations would change behavior, but not how stipulations might affect representations. Three- and 5-year-olds confused pretenses and conventions; 7-year-olds consistently…

Notes contemporary models of human development have expanded to address a wider set of issues underlying personal change. Discusses the social cognitive model of self-regulatory development. Emphasizes the crucial development of self-regulatory competence: the point at which the processes of development become fully and reciprocally interactive…
