The effects of delay of information feedback interval (0 or 7 seconds), postinformation feedback interval (1, 8, or 15 seconds), difficulty (one or three variable irrelevant dimensions), and presence or absence of a tractor in the postinformation feedback interval were investigated with 240 junior high school children in a modified…

Study of children's retention of training in class inclusion reasoning skills. Sixty-four kindergarten-age children who showed no evidence of class inclusion skills were assigned to one of three groups: training, training with corrective feedback, and control. Posttests were administered immediately after training and 3 months later. (Author/BN)

In two studies, children participated in route-planning tasks in which they were asked to find the shortest path to retrieve certain items. In Study 1, children participated in two versions of the task (standard versus feedback) differing in the amount of contextual support. Forty-eight children, ages 6, 8, and 10 years, had to help their…

Subjects from kindergarten-age to adult participated in four experiments. In order to view the stimuli, subjects in three experiments activated lights in viewing boxes; in the fourth experiment, stimulus fixations were measured using a corneal reflection technique. Results supported the view that visual observing is controlled by cognitive…

The question of how children represent and use comparative or partially ordered information is examined. Two experiments tested a conjecture that a common representation, a linear order, underlies the processing of all comparatives. (Author/MS)

Results confirmed that children differentially use knowledge of results and suggested that any description of motor skill acquisition must account for the complex interaction between developmental level and the difficulty of the task at hand. (Author/DB)

Over the course of development, the ability to switch between different tasks on the basis of feedback cues increases profoundly, but the role of performance monitoring remains unclear. Heart rate indexes can provide critical information about how individuals monitor feedback cues indicating that performance should be adjusted. In this study,…

This paper reports two experimental studies of the development of time, speed and distance concepts in children. In Experiment I subjects (12 in each of four age groups: 5-, 8-, 11-year-olds, and adults) were asked to judge which of two electric trains on parallel tracks went faster, for the longer distance, or for more time. Subject's knowledge…

A study was conducted in light of a neo-Piagetian theory of cognitive development to interpret the effect of priming executive schemes for describing relevant features in a referential communication task. Forty-eight 4-year-old children were divided into primed and nonprimed groups and were asked to describe in isolation a black and white…

Examined the relationship between 7-, 9-, and 11-year old children's performance on a battery of selected Piagetian measures and on a proportional reasoning task. Found a strong relationship between stage level and (1) the complexity of hypotheses used, (2) the use of the proportional hypothesis, and (3) the overall use of logical hypotheses. (HOD)

This article presents a rationale for emphasizing discovery instruction over guided instruction in teaching cane travel skills to people with severe visual impairments. Discovery instruction is seen to facilitate the use of intrinsic feedback in developing perceptual-cognitive skills as well as promoting problem solving, retention, and transfer of…

Performance data for 42 subjects pertaining to seven course objectives and ten propositional logic tasks were analyzed for hierarchical relationships using ordering theoretic technique. The resulting hierarchy indicated that simple implication and particular contraposition propositional logic tasks were prerequisite to some course objectives. This…

Challenges the assumptions concerning the necessity of feedback in children's cognitive development. Suggests that during a certain and limited phase, cognitive development may occur due to cognitive restructuring. Discusses the implications of this for educational programs, especially computer assisted learning. (MJP)
