Examined Korean first, third, and fifth graders' judgments about authority commands regarding moral events. Found that children judged that a principal, teacher, class president, and child without an authority position have legitimacy and should be obeyed when giving morally right directives. Children gave greater legitimacy to persons giving…

Extends dynamic attending theory to developmental questions concerning tempo and time hierarchies. Compares performance of 4- to 10-year-olds, and adults on dynamic attending activities. Suggests that growth trends could be expressed in terms of listeners' engagement of slower attending oscillators with age and musical experience, accompanied by…

Two experiments investigated infants' sensitivity to amount of continuous quantity and to changes in amount of continuous quantity. Found that 6-month-olds looked significantly longer at a novel quantity than at the familiar quantity. Nine-month-olds looked significantly longer at an impossible event than at a possible event. Findings question…

Contrary to assumptions about aversive effects of competition on achievement motivation, in this study young people saw academic contests as fair. When participants completed structural interviews on fair ways to organize science contests and on differentiation of skill and luck, age-related trends in their conceptions of procedural justice were…

A study examined theory of mind acquisition in 34 children (ages 5- 10) with deafness using four traditional false-belief tasks. Results indicate the age of the child was strongly related to theory of mind development and that the children were delayed by approximately 3 years in this cognitive developmental milestone. (Contains references.)…

Activation of change processes in cognitive capacity of 71 institutionalized adults with mental retardation in four age groups was investigated after the Instrumental Enrichment Program. The initial and final test scores of adults with Down syndrome were lower than those of adults with other forms of mental retardation. (Contains extensive…

Examined the development of children's conceptual understanding of attention by focusing on their awareness of various subtypes of attention. Found three changes with increasing age: (1) less emphasis placed on surface features of scenarios used in similarity judgments; (2) more attentional subtypes identified; and (3) more emphasis placed on the…

Reviews literature on children's use of metaphors, focusing on how metaphorical language is used in the learning process and the implications for teachers in helping their students use metaphorical language and thereby build knowledge of the world. Asserts that teachers need to speak metaphorically and that conversation, writing, and literature…

Analyzed 1.5- and 2.5-year-olds' problem solving and learning. Found that changes in toddlers' strategies could be assessed reliably on a trial-by-trial basis, that changes followed the basic form predicted by the overlapping waves model, and that analyses could reveal information about the qualitative and quantitative aspects of their learning.…

This study focuses on the ability of deaf children to predict the behaviours of other people, based on an understanding of their beliefs. An unexpected transfer task and a deceptive box task were used with a group of 55 severely/profoundly deaf children. Results reiterate the findings of other studies that many deaf children are grossly delayed in…

The ability to critically evaluate whether information presented actually supports a given claim is essential for cognitive and social development. This paper presents a study focusing on developmental and contextual aspects of this ability (called antilogos). We tested antilogos for different variables: age group (Grades 8 and 10), direction of…

Absent reference comprehension is a critical achievement of early development, yet little is known about its emergence. In the current study, 12- and 16-month-old infants' recognition of properties of mentioned absent things was used as an index of absent reference comprehension. Infants were presented with displays matching the color and prior…

The Kuhn and Pease (p. 279, this issue) article advances the fields of cognitive development and learning by integrating work on executive functions, metacognition, and scientific reasoning. The article also expands developmental work to older children and adults, to personal beliefs, and to social information, and reinvigorates the construct of…

Research using the Dimensional Change Card Sort (DCCS) showed that young children are usually able to sort accurately by an initial rule but are unable to switch to a new rule when the two rules conflict. In 2 experiments, the DCCS was modified to study the effects of feedback on 3- to 5-year-old children in a problem-solving task. In Experiment…

This article describes how parents foster emotional development in their children through the words they speak during daily conversations. The author presents a case study of a father and his infant daughter and the developmental progression of talk. In the first 6 months of life, talk revolved around the infant's feelings, and later in the…
