Editor's Note: These short reviews of a recent paper in the Journal, written exclusively by graduate students or postdoctoral fellows, are intended to mimic the journal clubs that exist in your own departments or institutions. For more information on the format and purpose of the Journal Club, please see Review of Khayat et al. At any instant, we are confronted with more information than we can...

Does perceptual grouping operate early or late in visual processing? One position is that the elements in perceptual layouts are grouped early in vision, by properties of the retinal image, before perceptual constancies have been determined. A second position is that perceptual grouping operates on a postconstancy representation, one that is available only after stereoscopic depth perception, l...

This article describes a graduate course on the subject of \Reactive and Real-Time Systems", which serves as the basis for courses taught by the authors at Bar-Ilan University and at Tel-Aviv University, and undergraduate course at the Netania Academic College and The Academic College of Tel-Aviv-Yaao. The course focuses on the development of provably correct reactive or real-time systems. It i...

To measure dynamic visuo-motor coupling within the two hemispheres, we showed observers an animation of a rotating cup. They indicated with left or right buttons when a Wxation dot in the center of the animation changed color. For either hand, response times changed continuously with the irrelevant position of the cup’s handle, even when the perceptual asymmetry of the handle was controlled. Th...

Linguistic analyses suggest that common and seemingly simple expressions, such as began the book, cannot be interpreted with simple compositional processes; rather, they require enriched composition to provide an interpretation, such as began reading the book (Jackendoff, 1997; Pustejovsky, 1995). Recent reading time studies have supported these accounts by providing evidence that these express...

In four experiments, we investigated the time course of attentional focusing. Our main aims were to estimate the time necessary for focusing to take place and the time over which focal attention can be maintained. The use of a pre-cueing procedure allowed us to estimate the time necessary for focusing, excluding the time needed for orienting. The results of the ® rst three experiments showed th...

BACKGROUND Because the incubation period of scrapie has a strong host genetic component and a dose-response relationship, it is possible that changes will occur during an outbreak, especially in the genotypes of cases, age-at-onset of disease and, perhaps, the clinical signs displayed. We investigated these factors for a large outbreak of natural scrapie, which yielded sufficient data to detect...

The notion of action simulation refers to the ability to re-enact foreign actions (i.e., actions observed in other individuals). Simulating others' actions implies a mirroring of their activities, based on one's own sensorimotor competencies. Here, we discuss theoretical and experimental approaches to action simulation and the study of its representational underpinnings. One focus of our discus...

Characterizing the genome-wide dynamic regulation of gene expression is important and will be of much interest in the future. However, there is currently no established method for identifying differentially expressed genes in a time course study. Here we propose a significance method for analyzing time course microarray studies that can be applied to the typical types of comparisons and samplin...

A common weakness of local search metaheuristics, such as Simulated Annealing, in solving combinatorial optimisation problems, is the necessity of setting a certain number of parameters. This tends to make significantly increase the total amount of time required to solve the problem and often requires a high level of experience from the user. This paper is motivated by the goal of overcoming th...
