Five- and 6-year-olds heard stories in which a character sorted items into two locations. Found that children could reject a report of the character's belief when the character had a false belief more easily than a belief in which an object known to the character was described using an unknown term. Children found it easier to predict incorrect…

Data obtained under naturalistic conditions do not support the notion of a close fit between the growth of geometric concepts during the concrete operational period and "realism" in art. Realism here refers to the ability to portray the objective proportions of a figure, to coordinate spatial relations and distances, and to represent a…

If human cognitive development advances through a series of broad and general stages, then the child's mind at any developmental point should seem consistent and similar across situations in its maturity level and general style. However, there appear to be factors and conditions that promote homogeneity and heterogeneity in the child's cognitive…

Seven-year-olds and university students were questioned about hidden or visible colored counters. Under certain testing conditions, the children were able to demonstrate one of the major characteristics of formal operational thought, namely the ability to reason in terms of verbally stated hypotheses without reliance on direct, physical…

To investigate developmental differences, preschoolers' performance on four tasks frequently used to measure their understanding of causal and temporal relationships was studied. Based on an analysis of cognitive processes involved in recognition, completion, construction/seriation, and verbal explanation tasks, the prediction was made that…

A total of 41 children ranging in age from 9 months to 6 years, 6 months of age were observed playing at game-like tasks. Disruptive interventions were made at different times and with different levels of intensity. Children's reactions revealed developmental stages in wanting to do things by themselves; stages varied with the development of…

This study questioned whether children's relative inability to use the two cerebral hemispheres independently contributes to their difficulty with the simultaneous execution of conflicting tasks. Two naming tasks involving the identification of upright and inverted letters were employed; conditions differed according to how the letter pairs were…

Preoperational and concrete-operational first and second graders performed on a training task and a generalization task prior to and after serving in one of five instructional groups. The instructional groups were: no-training control, specific self-instruction, specific didactic control, general self-instruction and general didactic control.…

Two experiments yield data suggesting that the structure of children's concept of artifact function changes profoundly between age 5 and 7, with striking effects on problem-solving performance. This effect is not caused by differences in children's knowledge about the typical use of particular tools, but rather, is mediated by the structure of the…

Presents evidence that the supposed paradox in which infants find abstract patterns in speech-like stimuli whereas even some preschoolers struggle to find abstract syntactic patterns within meaningful language is no paradox. Asserts that all research evidence shows that young children's syntactic constructions become abstract in a piecemeal…

Asserts that the posited paradox between infancy and toddlerhood language was not eliminated by Tomasello and Akhtar's appeal to infants' robust statistical learning abilities. Maintains that scrutiny of their studies supports the resolution that abstracting linguistic form is easy for infants and that toddlers find it difficult to integrate…

Three studies explored whether children's tendency to extend object names on the basis of sameness of shape (shape bias) is specific to naming. Findings indicated that 2- and 3-year-olds showed shape bias both when asked to extend a novel name and when asked to select an object of the same kind as a target object; 3-year-olds also showed shape…

Three experiments explored change toward more flexible reliance on combinations of spatial and nonspatial landmark information to reorient oneself. Identified 5-7 years as age for this developmental change. Results suggest that language production skills play a causal role in allowing humans to construct novel representations rapidly, which can…

This article reviews some current principles of brain research, including the idea that intelligence and its nurture is no longer restricted to the linear, rational cognitive function, but includes the integration of the cognitive (linear and spatial), emotional-social, physical, and intuitive. The principles of teaching and learning supported by…

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.
