Kv4 channels regulate the backpropagation of action potentials (b-AP) and have been implicated in the modulation of long-term potentiation (LTP). Here we showed that blockade of Kv4 channels by the scorpion toxin AmmTX3 impaired reference memory in a radial maze task. In vivo, AmmTX3 intracerebroventricular (i.c.v.) infusion increased and…

Previous research suggests that 3-year-olds fail to learn from statistical data when their prior beliefs conflict with evidence. Are children's beliefs entrenched in their folk theories, or can preschoolers rationally update their beliefs? Motivated by a Bayesian account, we conducted a training study to investigate this question. Children (45…

After more than 100 years of interest and study, knowledge transfer remains among the most challenging, contentious, and important issues for both psychology and education. In this article, we review and discuss many of the more important ideas and findings from the existing research and attempt to bridge this body of work with the exciting new…

Intuitive predictions and judgments under conditions of uncertainty are often mediated by judgment heuristics that sometimes lead to biases. Using the classical conjunction bias example, the present study examines the relationship between receptivity to metacognitive executive training and emotion-based learning ability indexed by Iowa Gambling…

The primary concern in current interaction design is focused on how to help users solve problems and achieve goals more easily and efficiently. While users' sufficient knowledge acquisition of operating a product or system is considered important, their acquisition of problem-solving knowledge in the task domain has largely been disregarded. As a…

The present study attempted to identify and describe individual differences in concept learning. It was hypothesized that if a significant portion of the reliable individual variation in a complex learning situation could be identified and described, it would be reasonable to expect that subsequent predictions could be made about the conditions…

The model stresses interactions among specific combinations of cognitive task requirements, learner characteristics, and instructional treatment properties, in a manner analogous to the aptitude-treatment interaction (ATI) model. "Supplantation" is the provision of overt assistance to learners in performing a specific process required by…

This essay, the concluding section of a larger study, examines the present state of cognitive science and instructional theory as reflected in the study's earlier chapters. Cognitive analyses of tasks are reported in the broad domain of language comprehension and production (e.g., understanding, composing, and answering questions about texts). The…

An instructional system that is both efficient and effective should present information so that it is easily processed by learners and so that the cognitive structures resulting from instruction correspond to the structure of the content to be learned. This paper presents a discussion of methods for describing content structure and cognitive…

A conservation problem of numerical equivalence which 80% of adults reliably fail and 40% of third graders pass was developed, and responses of 188 subjects (Grades 2, 3, 5, 7, 9, 11 and college) to it and related number conservation and probability problems indicated that the differences in nonconservation were rooted in subjects' different…

A review is presented of the role of algorithms in learning and instruction. The paper first describes an algorithm as a procedure guaranteed to produce a correct result and lists its features as: 1) having a reasonably finite number of unambiguously defined operations; 2) having zero or more inputs from a specified domain; 3) having outputs with…

The authors argue against the current view of task analysis which assumes that learning is a univariant process. They feel that learning is a multivariant process and that task analysis should also take into consideration an analysis of the learning task, the cognitive processes which affect the acquisition of the learning task, and the learner's…

The work of a three-year series of experimental studies of human cognition is summarized in this report. Proglem solving and learning in man-machine interaction was investigated, as well as relevant variables and processes. The work included four separate projects: (1) computer-aided problem solving, (2) computer-aided instruction techniques, (3)…
