A developmental reversal in accuracy was obtained for third and sixth graders and adults who judged class membership of patterns presented in a same-different task. Reversal accuracy appeared to result from an increase with age in orientation-free judgments. This hypothesis was confirmed in the subsequent two experiments. (GO)

Investigated the development and fragmentation of categories over chronological and mental age without the requisite of free recall. Kindergarten, fourth grade, ninth grade and retarded students labeled and categorized chromatic slides of picturable objects. (GO)

Multiple classification refers to the combination of the common attribute of one class with the common attribute of another class such that the multiple class is defined by the simultaneous presence of both attributes. (Authors)

Thirty-six TESL trainees of three different age groups used classroom theory and practical experience to shape their own knowledge of English grammar. Participants completed a series of three grammatical explanation tasks over the course of two academic terms. Analysis of results revealed that the two groups of older trainees (23-34 years and…

Magnitude is assumed to be represented along a holistic mental number line in adults. However, the authors recently observed a unit-decade compatibility effect for 2-digit numbers that is inconsistent with this "holisticness" assumption (H.-C. Nuerk, U. Weger, & K. Willmes, 2001). This study used the compatibility effect to examine whether the…

This experiment investigated relational complexity and relational shift in judgments of auditory patterns. Pitch and duration values were used to construct two-note perceptually similar sequences (unary relations) and four-note relationally similar sequences (binary relations). It was hypothesized that 5-, 8- and 11-year-old children would perform…

A sample of 315 children aged between 6 and 9 years participated in a 5-month longitudinal study aimed at investigating constraints on representational flexibility as observed in drawing behaviour. The study specifically looked at how external interventions affected children's representations over time. The intervention involved showing children…

Developmental changes in children's verbal fluency were explored in this study. One hundred and forty children aged from 7 to 16 completed four verbal fluency tasks, each with a different the production criterion (letter, sound, semantic, and free). The age differences were analyzed both in terms of number of words produced, and clustering,…

Purpose: The present study investigated the extent of cortical activity during overt picture naming using functional magnetic resonance imaging (fMRI). Method: Participants comprised 20 healthy, adult participants with ages ranging from 20 to 82 years. While undergoing fMRI, participants completed a picture-naming task consisting of 60…

This paper provides a detailed empirical account of the performances of 8- to 9-year-olds and 11- to 12-year-olds on a chore-scheduling task developed to assess the dynamics of planning processes. In developing the planning task for revealing different levels of planning proficiency, five critical aspects of planning were taken into account: the…

Cognitive perspective-taking has attracted considerable attention in the mainstream developmental literature, and is most commonly studied under the rubric of Theory of Mind. The current article reviews the levels of understanding of informational states that are believed to underlie cognitive perspective-taking from this conceptual framework. An…

Black and white kindergarten and second-grade children were tested for accuracy of detection and recognition of orientation and location changes in pictures of real-world and geometric figures. The purpose was to test children's ability to detect and remember objects in a visual display. (Author/CS)

The impact of "Misterogers Neighborhood" on nursery school children's prosocial behavior was assessed. Specifically, two hypotheses were tested: (1) that children who viewed several "Misterogers Neighborhood" programs would evidence more prosocial behavior than would nonviewers, and (2) that young viewers would show an increase…

Investigates to what extent discrimination learning through time delay of multistimulus, distinctive-feature prompts is a function of the inclusion and configuration of the S-prompt. Results of two experiments with children aged four and five indicate that most subjects did not learn the task assigned unless two distinctive-feature prompts were…

Describes four experiments conducted among adults and 3- to 7-year-olds to validate a task analysis that indicates that the equality, group enhancement, and superiority social decisions require a greater information processing load than the altruism, rivalry, and individualism social decisions.
