Here, we assess whether quantity representations are influenced by the perceptual biases hypothesized to manifest in depressive individuals. In contrast to this clinical model, several prominent models of numerical cognition assume that quantity representations are abstract, and therefore are independent of the items that are being quantified. If…

The article is devoted to the issue of learning from the cognitive perspective. As life-long learning is an integral part of our modern life, the authors were attracted by the phenomenon when even young people demonstrate cognitive "resistance" to learning. This particular study is focused on cognitive destructions as challenges to…

This study focused on the effect of examinees' ability levels on the relationship between Reflective-Impulsive (RI) cognitive style and item response time in computerized adaptive testing (CAT). The total of 56 students majoring in Educational Technology from Shandong Normal University participated in this study, and their RI cognitive styles were…

The focus of this study is the relationship between students' performance in mental calculation and the strategies they use when solving three-digit mental addition problems. The sample comprises 78 4th grade students (40 boys and 38 girls). Their mean age was 10 years and 4 months. The main novelties of the current research include (1)…

Participants read a series of news articles, each containing a target event followed by 2 causes. To study the ease with which readers update their mental representation as they proceed through the text, the certainty of the first cause was manipulated: It was presented as either a certain explanation of the subsequent target event or as a…

In an experiment with 109 undergraduates, we examined the effect of mood, cognitive style, and cognitive ability on implicit learning in the Artificial Grammar (AG) and Serial Reaction Time (SRT) tasks. Negative mood facilitated AG learning, but had no significant effect on SRT learning. Rational cognitive style predicted greater learning on both…

Mean response times and slope of response times were correlated with intelligence and achievement for 94 sixth-graders. Mean response time reliability was greater than that of slope, and correlated significantly with IQ and achievement. Speed of processing information generalized across experimental tasks and reliably indicated intellectual…

This paper reports two studies which examined the relationship between problem solving strategies, response latencies, and efficient performance on measures of conceptual tempo. Study I demonstrated that teaching 8-year-old children to use efficient strategies on problem-solving tasks increased both the quality of their performance and their…

Cognitive development and various educational implications are discussed in terms of Donald Saari's model of the interaction of a learner and the enviroment and the constraints imposed by the inefficiency of the learner's cognitive system. Saari proposed a hierarchical system of cognitive structures such that the relationships between structures…

Cognitive style was modified in a sample of 50 impulsive and 50 reflective fourth-grade boys. Subjects viewed a film-mediated model displaying a response style opposite to their own cognitive style. The specific cues in the model's behavior which facilitated shifts in cognitive style varied with the intellectual levels of the subject. (Author/WY)

This book is designed to be a quick and easy resource for anyone teaching physics for the first time. Written after extensive research, this book is filled with reliable labs, demos and activities that work well in the classroom. Also included are lesson plans, diagrams, and teacher notes for every activity. The book is not the end--it is just a…

The notion that elderly adults respond more slowly than younger adults in order to ensure accuracy was investigated. The Matching Familiar Figures Test was administered to 10 males and 10 females from each of the following age groups: 30-39, 40-49, 50-59, 60-69, and 70-79 years old. (Author/SS)

This study was designed to determine the relationship between children's reflection-impulsivity and responses to a forced choice of a toy for play (labelled as impulsivity) and the length of continued play with the selected toy (labelled as latency). A group of twenty four-year-olds, male and female, were observed making a choice between toys. The…

Several varieties of perceptual independence are investigated, including sampling independence, dimensional orthogonality, stimulus separability and integrality, and performance parity. A general multivariate perceptual theory is developed, and a precise definition of perceptual independence is offered. (Author/LMO)

Investigates the differential effect of modeling procedures on slow and fast responders' performance on a haptic-visual matching test. Also studies the differential effect of modeling of impulsive v reflective modes of responding, and of model success v model failure. (Author/SS)
