U-shaped developmental functions, and their N-shaped cousins, have intrigued developmental psychologists for decades because they provide a compelling demonstration that development does not always entail a monotonic increase across age in a single underlying ability. Instead, the causes of development are much more complex. Indeed,…

Background: Deficits in autism have been characterised as a bias towards local over global processing. This paper examines whether there is a deficit in gestalt grouping in autism. Method: Twenty-five low-functioning children with autism and 25 controls who were matched for chronological age and verbal mental age took part in the study. Results:…

Children's developing competence with symbolic representations was assessed in 3 studies. Study 1 examined the hypothesis that the production of imaginary symbolic objects in pantomime requires the simultaneous coordination of the dual representations of a dynamic action and a symbolic object. We explored this coordination of symbolic…

To evaluate the claim that correct performance on unexpected transfer false-belief tasks specifically involves mental-state understanding, two experiments were carried out with children with autism, intellectual disabilities, and typical development. In both experiments, children were given a standard unexpected transfer false-belief task and a…

The study tested the effect of aerobic exercise training on executive function in overweight children. Ninety-four sedentary, overweight but otherwise healthy children (mean age = 9.2 years, body mass index [greater than or equal to] 85th percentile) were randomized to a low-dose (20 min/day exercise), high-dose (40 min/day exercise), or control…

Worldwide interest in work and learning is generating a large volume of disparate disconnected studies which can help improve the understanding of both work and learning as separate domains, but which lack an overall perspective. This paper proposes the outline of a conceptual framework for relating work and learning by an individual worker as a…

Pictures are often used by cognitive psychologists to investigate the development of cognitive functions. Different attributes of the picture, such as object or picture familiarity, word frequency, and age of acquisition, are known to correlate with naming latency and to affect memory, particularly retrieval processes. But without the use of…

Some studies of young children's understanding of false belief have generated controversy, even to the extent that others' failure to replicate these studies was viewed as problematic. A Vygotskian perspective on internalization enables researchers to reverse the classic developmental competence-performance distinction, and to argue that the…

Since E.L. Thorndike's landmark 1917 study of the complexity of reading comprehension, inferential research has generally focused on either inference as a developmental process or the nature of inferences made during reading. In his 1930 study, R. W. Tyler established that inference could be objectively measured. S. G. Paris conducted several…

This report, written in Finnish with a 10-page summary in English, concerns research on the interrelationship between Piagetian operations, various aspects of information processing capacity and mathematical thought processes and strategies related to number and measurement. In a theoretical discussion, Piaget's research on mathematico-logical…

The Stanford-Binet Intelligence Scale-Revised and the Kaufman Assessment Battery for Children (K-ABC) were compared using a sample of 26 developmentally disabled children, aged 32 to 73 months. The focus of the study was to determine the feasibility of the K-ABC both for assessment and for planning more effective remediation programs for this…

A study used structure mapping theory to examine the claim that children can understand metaphors based on shared object attributes before understanding those based on shared relational structure. The three kinds of metaphor used in the study varied in whether the shared information forming the basis for the interpretation was attributional,…

Several researchers have examined the relationship between scales of the Inventory of Learning Processes (ILP) and the academic performance of college students. This study sought to determine whether there were significant correlations among levels of processing, locus of control, and achievement for college students. Subjects (N=50) enrolled in…

This paper discusses the utility of a general systems theory paradigm for psychology. The paradigm can be used for conceptualizing such complex phenomena as change over time in living systems, person-society interactions, and the epistemology of multiply determined changes. Consideration is also given to applications of the approach to…

This paper presents research on a theoretical approach to Logo as a programming language that creates a context for learning in which the process by which children learn and develop, using computers, is of greater interest than the products, or outcomes, of learning. Concerned with the cultural context of Logo learning and principles upon which it…
