Hemispheric differences in stop task performance.

This study examined hemispheric specialization for stop task performance. It was found that inhibitory performance was better for stop signals presented in the right visual field. This result provided support for the hypothesis that, during stop task ...

Electrophysiological correlates of attentional orientation in humans to strong intensity deviant nociceptive stimuli, inside and outside the focus of spatial attention.

Laser evoked potentials (LEPs) are electrical brain responses to nociceptive heat stimuli. In a recent study [Legrain, V., Guérit, J.M., Bruyer, R. and Plaghki, L., Pain, 99 (2002) 21-39.], we found that amplitude at approximately 400 ms was increased by ...

Collision and violation involvement of drivers who use cellular telephones.

The study sample consisted of 3,869 drivers, split approximately 50/50 between observed cell phone users and those observed not using cell phones (labeled "nonusers"). Cell phone use was determined by a snapshot observation made on city streets. The ...

Global feature-based attention for motion and color.

We used a divided attention psychophysical task to test the hypothesis that visual attention to a stimulus feature(1) facilitates the processing of other stimuli sharing the same feature. Performance on a dual-task was significantly better when human ...

The Madrid card sorting test (MCST): a task switching paradigm to study executive attention with event-related potentials.

Event-related potentials (ERPs) provide valuable information about the fast brain dynamics subserving cognitive functions such as attention and working memory. Most ERP studies employ cognitive paradigms with a fixed task-set (i.e., press a button to ...

The power of human brain magnetoencephalographic signals can be modulated up or down by changes in an attentive visual task.

This paper presents evidence indicating that the signals generated by neural responses to visual input can be either enhanced by increasing or suppressed by decreasing the area of the stimuli to which attention is directed. We used magnetoencephalography ...

The effect of dehydroepiandrosterone (DHEA) on recognition memory decision processes and discrimination in postmenopausal women.

In this article, the theoretical distinction between recognition memory decision and discrimination processes is used to explore the effect of dehydroepiandrosterone (DHEA) in postmenopausal women. DHEA is an adrenal steroid that diminishes with aging. ...

The impact of spatial cues on preschoolers selective attention.

The effects of spatial arrangement on preschool childrens ability to selectively attend were investigated. Three- and 4-year old children were shown a multicolor dollhouse room intended to serve as a special place containing miniature chairs and models ...

Pre-frontal executive committee for perception, working memory, attention, long-term memory, motor control, and thinking: a tutorial review.

As an explicit organizing metaphor, memory aid, and conceptual framework, the prefrontal cortex may be viewed as a five-member Executive Committee, as the prefrontal-control extensions of five sub-and-posterior-cortical systems: (1) the Perceiver ...

Class size, pupil attentiveness and peer relations.

BACKGROUND: Despite a long-running debate over the effects of class size differences on educational performance there is little evidence on the classroom processes that might be involved. AIMS: The effects of class size differences are examined in ...
