A growing need for utilizing school-based HIV/AIDS interventions the world over has been acknowledged as the most cost-effective means for arresting the spread of the HIV/AIDS pandemic among the vulnerable youth. However, the question on how teachers as educational change agents and cognitive sense-makers of HIV/AIDS curricula situated in a…

What prompts the students to respond in online dialogic discussion? Why some students chose to fall out? This case study through the lens of phenomenography observation attempts to explain the five decision steps of students to respond in Meta-cognitive Learning in Free Online Groups (MetaL-FrOG) discussion. It presents a part of a research…

Two experiments probed 8-month-olds' ability to represent different kinds of entities: rigid, cohesive objects; flexible, cohesive objects; and non-rigid, non-cohesive portions of sand. Results suggest that the processes by which infants individuate and track entities are sensitive to material kind, rigid cohesive objects occupy a privileged…

Most accounts of the Stroop effect (Stroop, 1935) emphasize its negative aspect, namely, that in particular situations, processing of an irrelevant stimulus dimension interferes with participants' performance of the instructed task. In contrast, this paper emphasizes the fact that, even with that interference, participants actually can (and…

A model is proposed that relates the personality dimensions of introversion-extraversion, achievement motivation, and anxiety to efficient cognitive performance. This general information-processing model also accounts for the systematic effects of motivational states on sustained information transfer and some aspects of short-term memory.…

Conducted meta-analysis to examine empirical inconsistencies and theoretical controversies concerning false-belief tasks and understanding about mental states. Found that a combined model including age, country of origin, and four task factors accounted for 55 percent of the variance in false-belief performance. Findings are consistent with…

In response to empirical evidence that suggests that children use more than one strategy in transitive inference tasks, an effort was made to model strategy development as it occurs under the dual constraints of a concept of order and task demands. In the model, when a task is presented, procedural memory is searched for a strategy that is…

This paper analyzes the effect on performance when several active processes compete for limited processing resources. The principles discussed show that conclusions about the interactions among psychological processes must be made with caution, and some existing assumptions may be unwarranted. (Author/BJG)

Offers a sketch of a concept called the "liminal state" that may represent a central element of designing and a condition that facilitates the best design products and processes. A definition of "liminal state," some contexts in which it may occur, and some areas where liminal states might improve performance are given.…

Four experiments examined very young infants' expectations about containment events. Found that 2- to 3.5-month-olds recognized that objects could be lowered inside a container with an open but not a closed top. Three-and-a-half-month-olds realized that objects could not pass through the container's back wall and should have moved with it to a new…

Three experiments examined children's strategic regulation of memory accuracy. Found that younger (7 to 9 years) and older (10 to 12 years) children could enhance the accuracy of their testimony by screening out wrong answers under free-report conditions. Findings suggest a developmental trend in level of memory accuracy actually achieved.…

Current theories of environmental cognition typically differentiate between an online, transient, and dynamic system of spatial representation and an offline and enduring system of memory representation. Here the authors present additional evidence for such 2-system theories in the context of the disorientation paradigm introduced by R. F. Wang…

This paper reviews the aspects of cognitive science that relate best to using electrical and magnetic recording to understand the function of brain systems. It outlines a framework for relating cognitive activities of daily life (typing, reading) to underlying neural systems. The framework uses five levels of analysis: task, elementary operations,…

Reviews evidence that children use diverse cognitive strategies; discusses the adaptive value of using diverse strategies; describes models of strategy choice based on rational calculations; and presents an overview of the distributions of associations model of children's strategy choice. (RH)
