THE COPYING OF UPRIGHT AND TILTED SQUARES BY SWAZI CHILDREN AND ADULTS

Children aged 5–12, and adults from a rural area of Swaziland, along with urban based adults were assessed on their copying ability for a square orientated in two ways, squarely and obliquely; and under five different conditions. The children and rural adults experienced significant difficulties in copying the obliquely orientated shape, while the urban adults produced the shape without difficulty, although they all easily perceived the shapes and programmed the required movements. The results indicate that the process of planning the fine movements for drawing is learned, improves with age, and practice is necessary. Where planning is more complex, in the production and combination of oblique lines, it appears that the lack of practice in Swazi rural schools, and generally little requirement to use the skills, results in a delay of those particular drawing abilities.     

Evolving Development: An Evolutionary Perspective on Development for an Interconnected World

The notion of development has been permeated by concepts and methods from positivistic science. As a result, many development initiatives are reductionistic, myopic, and with little or impact on the improvement of the quality of life and the sustainability of communities and societies. This article marks the beginning of a transdisciplinary inquiry among the authors, motivated by direct interest in the issue of development, per se, and in particular, Mexico's development. Our inquiry departs from and weaves together our various areas of expertise and experience, including: systems theory, general evolution theory, economic development, technology transfer, social innovation, sustainable development, environmental behavior, social systems design, and education. The article reviews the concept of development from an evolutionary and systemic perspective. It outlines the foundations of evolutionary development in terms of theory, philosophy, and methodology and provides a conceptual framework for future research aimed at the articulation of a practical model for evolutionary development.     

Recovery of Lost Transfer Effects

Tracking tasks known to facilitate or interfere with one another were investigated under various sequences of alternation. Double and treble alternating sequences of 2 tasks were used. 6 groups of 12 Ss practiced for 20 10-sec. trials, with 50-sec. intertrial intervals. Trend analyses were employed in comparing the results of the double and treble alternating sequences with the single alternating sequence and postshift trials of the previous study (Laszlo & Pritchard, 1969). The results showed that facilitation or interference lost with single alternation was recovered with double or treble alternating sequences. Rate and degree of recovery appeared to depend upon the degree of transfer between tasks and strategies employed by S. These results were discussed in terms of motor program consolidation.     

Much ado about norming: The Behavior Rating Inventory of Executive Function

The Behavior Rating Inventory of Executive Function (BRIEF) is a rating scale designed to assess executive functions in everyday life that is widely used in school and clinical settings and in research studies. It has been recently suggested, however, that the limited geographic stratification of the standardization sample renders the measure overly sensitive. We evaluated this hypothesis by examining BRIEF scores across studies of typically developing children and adolescents. Thirty-nine studies were identified that included at least one of three possible index scores. Mean scores across studies were (a) within one to two T-score units from the standardization sample mean of 50, (b) tended to be slightly lower than 50, and (c) were unrelated to geographic location (US Census regions or internationally). These findings refute recent claims that the BRIEF is overly sensitive and further add to the large body of literature supporting the validity of the measure.     

Why I Believe in Science and Believe in God: A Credo

Abstract. The conflict between science and religion is not irremediable: the world concept of science is changing, and the change brings about a rapprochement with religious beliefs in some fundamental areas. One such area is the question of original creation. Recent findings regarding the nature of the universe show the improbability of its having arisen in the course of a random process. The perennial religious intuition of a transcendental act of creation is a logical entailment of the randomly entirely improbable fine tuning of the natural laws and processes that the observed universe manifests.     

The compression block technique

Remembering the distance or end-location of an interpolated movement interfered equally with the retention of criterion movement end-location. Interpolated distances were recalled less well than interpolated locations. These results were interpreted as evidence of capacity interference rather than structural interference with a visual/kinesthetic integrated store.
