Visual search strategies are indexed by event-related lateralizations of the EEG.

Two processes have been proposed for picking out information from a visual scene. A parallel process that detects salient features and a following serial process for higher order vision. However, this separation is still under dispute. The current study ...

The control of sequential aiming movements: the influence of practice and manual asymmetries on the one-target advantage.

The present experiment was conducted to explore the effect of practice on the one-target advantage in manual aiming, as well as asymmetries in intermanual transfer of training. Reaction and movement times for the first movement were longer in the ...

Cortical activation to illusory shapes as measured with magnetoencephalography.

Spatiotemporal patterns of cortical activation during the perceptual grouping of elements to form illusory shapes were estimated using anatomically constrained magnetoencephalography. Subjects were shown an array of Kanizsa-style figures which were ...

Test-retest reliability of chemosensory evoked potentials.

This study investigated the test-retest reliability of chemosensory event-related potentials in humans. Olfactory event-related potentials and chemosomatosensory event-related potentials were evaluated in 20 healthy, normosmic subjects. Phenyl ethyl ...

Negative facial expression captures attention and disrupts performance.

In two experiments, participants counted features of schematic faces with positive, negative, or neutral emotional expressions. In Experiment 1 it was found that counting features took longer when they were embedded in negative as opposed to positive ...

Inhibition of return using discrimination of location.

The present study investigated "inhibition of return" which refers to increased response latency when the target in a location discrimination task appears in the same location on consecutive trials. Location discrimination tasks were performed by 28 ...

Perceptibility of large and sequential changes in somatosensory information during leaning forward and backward when standing.

11 healthy young men served as subjects in two experiments on perceptibility of (1) large changes in foot pressure and muscle activity induced by body leaning and (2) sequential changes in pressure at the first toe and the head of the first metatarsalis ...

Individual stopping times and cognitive control: converging evidence for the stop signal task from a continuous tracking paradigm.

The present study introduces a continuous tracking procedure to investigate cognitive stopping in individual trials. Our measure of stopping performance had a mean similar to mean stopping times estimated in the stop signal paradigm, suggesting a common ...

The effects of acute doses of fexofenadine, promethazine, and placebo on cognitive and psychomotor function in healthy Japanese volunteers.

BACKGROUND: Genetic variations in cross-cultural metabolic capability may attenuate the lack of central nervous system effects of fexofenadine. OBJECTIVE: To compare the pharmacodynamics of fexofenadine and promethazine versus placebo in Japanese ...

Neural correlates of decision processes: neural and mental chronometry.

Recent studies aim to explain the duration and variability of behavioral reaction time in terms of neural processes. The time taken to make choices is occupied by at least two processes. Neurons in sensorimotor structures accumulate evidence that leads ...
