Medical student perceptions of factors affecting productivity of problem-based learning tutorial groups: does culture influence the outcome?

BACKGROUND: The popularization of problem-based learning (PBL) has drawn attention to the motivational and cognitive skills necessary for medical students in group learning. This study identifies the effect of motivational and cognitive factors on group ...

Implicit temporal tuning of working memory strategy during cognitive skill acquisition.

Complex cognitive tasks such as multiple-step arithmetic entail strategies for coordinating mental processes such as calculation with processes for managing working memory (WM). Such strategies must be sensitive to factors such as the time needed for ...

Psycholinguistics: a half century of monologism.

The contention of this article is that, since its inception in the mid-twentieth century, mainstream psycholinguistics has been monologistic, that is, has concentrated on monologue as its source of empirical material and has, largely implicitly, involved ...

The relationship between depression and smoking in adolescents.

The literature suggests that smokers are more likely to be depressed, while people who are depressed are more likely to smoke. The purpose of the present study was to determine the strength of the relationship between smoking, depression, intention to ...

Modeling the effect of task and graphical representation on response latency in a graph reading task.

We report an investigation into the processes involved in a common graph-reading task using two types of Cartesian graph. We describe an experiment and eye movement study, the results of which show that optimal scan paths assumed in the task analysis ...

Dehydroepiandrosterone (DHEA) and the aging brain: flipping a coin in the "fountain of youth".

The physiological role of dehydroepiandrosterone (DHEA) and its sulphated ester DHEA(S) has been studied for nearly 2 decades and still eludes final clarification. The major interest in DHEA derives from its unique pattern of activity. Its levels exhibit ...

Production compilation: a simple mechanism to model complex skill acquisition.

In this article we describe production compilation, a mechanism for modeling skill acquisition. Production compilation has been developed within the ACT-Rational (ACT-R; J. R. Anderson, D. Bothell, M. D. Byrne, & C. Lebiere, 2002) cognitive architecture ...

Steps toward building mathematical and computer models from cognitive task analyses.

Typically, detailed quantitative and computer models of human operators performing real world tasks cannot easily be developed. We propose a technique that more easily allows for that development. We propose that when a cognitive task analysis has been ...

Effects of head-slaved navigation and the use of teleports on spatial orientation in virtual environments.

The type of navigation interface in a virtual environment (VE)--head slaved or indirect--determines whether or not proprioceptive feedback stimuli are present during movement. In addition, teleports can be used, which do not provide continuous movement ...
