OBJECTIVE To test the hypothesis that, during random motor generation, the spatial contingencies inherent to the task would induce additional preferences in normal subjects, shifting their performances farther from randomness. By contrast, perceptual or executive dysfunction could alter these task related biases in patients with brain damage. METHODS Two groups of patients, with right and lef...

Humans appear to share with animals a nonverbal counting process. In a nonverbal counting condition, subjects pressed a key a numeral-specified number of times, while saying "the" at every press. The mean number of presses increased as a power function of the target number, with a constant coefficient of variation (c.v.), both within and beyond the proposed subitizing range (1-4 or 5), suggesti...

The neuronal correlates of handedness are still poorly understood. Here we used event-related functional magnetic resonance imaging to investigate the impact of handedness on neuronal activation of the primary sensorimotor cortex, supplementary motor area and dorsal premotor cortex during simple unilateral and bilateral finger movements. In 16 right-handed and 16 left-handed individuals, we map...

Mistakes in skilled performance are often observed to be slower than correct actions. This error slowing has been associated with cognitive control processes involved in performance monitoring and error detection. A limited literature on skilled actions, however, suggests that preerror actions may also be slower than accurate actions. This contrasts with findings from unskilled, discrete trial ...

In the briquetting process of various finely dispersed materials using auger pressing method, an important issue is extending service life and repairing worn-out elements, such as auger, die, lining. This study provides a literature review industrial experience in parts presses. It formulates main approaches for restoring abrasive surfaces presents results experimental studies aimed at prolongi...

This study is a comparison of AUPress with three other traditional (nonopen access) Canadian university presses. The analysis is based on the rankings that are correlated with book sales on Amazon.com and Amazon.ca. Statistical methods include the sampling of the sales ranking of randomly selected books from each press. The results of one-way ANOVA analyses show that there is no significant dif...

Brin, like other futurists, is very interested in the singularity, the point when humans have computer-enhanced intelligence, or strong AI exists. Brin believes that the singularity is approaching within the current generation, due to the acceleration in technological and social advances that started in the 15th century with the development of printing presses and glass lenses. Printing presses...
