It is well known that certain cognitive abilities decline with age. The ability to form certain new declarative memories, particularly memories for facts and events, has been widely shown to decline with advancing age. In contrast, the effects of aging on the ability to form new procedural memories such as skills are less well known, though it appears that older adults are able to acquire some ...

In this paper we describe an approach to the automated specification of procedural textures to be used in rendering, based on representative samples. Procedural textures exhibit many advantages over traditional surface texturing techniques, but unfortunately finding the correct procedural texture and appropriate parameters to create the desired texture can be a daunting task for even the most e...

BACKGROUND Sleep facilitates off-line consolidation of memories, as shown for learning of motor skills in the absence of concomitant distractors. We often perform complex tasks focusing our attention mostly on one single part of them. However, we are equally able to skillfully perform other concurrent tasks. One may even improve performance on disregarded parts of complex tasks, which were lear...

The striatum has been consistently implicated in the pathophysiology of obsessive-compulsive disorder (OCD), yet, studies assessing the performance of OCD patients in procedural learning tasks, assumed to rely on the intact functioning of the striatum, have yielded inconsistent results. Recently, Rauch et al. [Rauch SL, Savage CR, Alpert NM, Dougherty D, Kendrick A, Curran T, et al. Probing str...

Learning novel tasks is a complex cognitive activity requiring the learner to acquire diverse declarative and procedural knowledge. Prior ACT-R models of acquiring task knowledge from instruction focused on learning procedural knowledge from declarative instructions encoded in semantic memory. In this paper, we identify the requirements for designing computational models that learn task knowled...

Due to high cost and complexity of Intelligent Tutoring Systems (ITS), current systems typically implement a single teaching strategy, and comparative evaluations of alternative strategies are rare. We explore two competing strategies for teaching database normalization. Each data normalization problem consists of a number of tasks, some of which are optional. The first strategy enforces the pr...

This research examined the antecedents and consequences of identification with virtual teams. Specifically, we hypothesized that two structural characteristics (number of faceto-face meetings and task interdependence) and perceived quality of interaction (procedural and distributive justice) would be positively related to identification with the virtual team. A further hypothesis was that team ...

Offline verbalization about a new motor experience is often assumed to positively influence subsequent performance. Here, we evaluated this presumed positive influence and whether it originates from declarative or from procedural knowledge using the explicit/implicit motor-learning paradigm. To this end, 80 nongolfers learned to perform a golf-putting task with high error rates (i.e., explicit ...
