In four conditioned taste aversion experiments with rats as subjects, the effects of extinguished or pre-exposed flavors on retardation and summation tests was compared. Experiment 1 showed that when steps were taken to ensure similar exposure to the target flavor in all conditions, acquisition after pre-exposure and reacquisition after extinction…

Three experiments examined children's knowledge of harmony in Western music. The children heard a series of chords followed by a final, target chord. In Experiment 1, French 6- and 11-year-olds judged whether the target was sung with the vowel /i/ or /u/. In Experiment 2, Australian 8- and 11-year-olds judged whether the target was played on a…

Learning to discriminate between spatial locations defined by two adjacent arms of a radial maze in the conditioned cue preference paradigm requires two kinds of information: latent spatial learning when the rats explore the maze with no food available, and learning about food availability in two spatial locations when the rats are then confined…

In the adult brain, the expression of NT-3 is largely confined to the hippocampal dentate gyrus (DG), an area exhibiting significant neurogenesis. Using a conditional mutant line in which the "NT-3" gene is deleted in the brain, we investigated the role of NT-3 in adult neurogenesis, hippocampal plasticity, and memory. Bromodeoxyuridine…

Anxiety disorders are among the most common psychological disturbances in the industrialized world. Current behavioral therapy procedures for these disorders are somewhat effective, but their efficacy could be substantially improved. Because these procedures are largely based on the process of extinction, manipulations that enhance extinction may…

We investigated whether postextinction training infusion of PD098059, a selective inhibitor of mitogen-activated protein kinase (MAPK) activation, into the medial prefrontal cortex, would impair retention of extinction learning in rats. We found that immediate, but not late (2 or 4 h), postextinction infusion of PD098059 provoked a full return of…

Purpose: First, to explore the application of e-learning as a medium for workplace learning, as a form of adult learning and organisational learning from a theoretical point of view, second, to review empirical studies on recent solutions to pedagogical problems encountered in workplace learning in general and in e-learning in particular, and…

Purpose: The purpose of this paper is to argue that foundational terms in work-learning research, specifically "learning", "work", and "workplace", are inherently complex and contested as the same as their scope has expanded in different fields to elide various conceptual categories and theoretical positions. Yet…

Purpose: The aim of this paper is to show what the leaders themselves regard as the working ingredients in their mutual work situation that help to facilitate personal development. Design/methodology/approach: In the paper data were collected through semi-structured interviews with 14 leaders at low and middle management levels in different lines…

Purpose: The purpose of this paper is to argue that action learning (AL) may provide a means of successfully developing small to medium-sized enterprises (SMEs). Design/methodology/approach: The literature around SME learning suggests a number of processes are important for SME learning which similarity, it is argued, are encompassed in AL. AL may…

In the 1990s, one of Australia's police services moved from a centralised, academy-based system of training towards a more integrated model of professional development. As a consequence, probationary constables spent reduced time in the police academy (6 months) before moving into the workplace for 18 months of work-based learning. This paper…

Based upon the lessons learned and the educational materials generated from a doctoral course on qualitative data analysis, a group of doctoral students, their professor, and a linguistics consultant launched an on-going project to create a series of reusable learning objects designed to help other groups of students and professors learn how to…

Folkvine.org is a website that presents seven Florida folk artists, three guidebooks, and several scholarly bobble heads that make commentary on humanities topics, the artists, and their work. This article analyzes the website as an arts-based research project. Topics covered address issues of representation, translation, learning processes, and…

This article describes Cecilia Braslavsky's role in the development of theoretical frameworks based on empirical research that, in the stage of restoration of democracy in Latin America, made it possible to advance in the construction of a Latin American socioeducational paradigm. This article discusses some propositions that may systematize the…

Most trainers believe there are just two scientific approaches on which to base a training technology: behavioral psychology and cognitive psychology. There is a third scientific approach currently emerging that does deal with every kind of skill, and it comes from biology rather than psychology. This new approach is based on findings from…
