Source analysis of event-related cortical activity during visuo-spatial attention.

Recordings of event-related potentials (ERPs) were combined with structural and functional magnetic resonance imaging (fMRI) to study the spatio-temporal patterns of cortical activity that underlie visual-spatial attention. Small checkerboard stimuli ...

Rethinking the focusing effect in decision-making.

According to Legrenzi et al. [Cognition 49 (1993) 37], in making a choice people consider only the alternatives explicitly represented in their mental model of the decision situation. Their idea has found empirical support in the "focusing effect": ...

Comparing the sensitivity of manual pursuit and perceptual judgments to pictorial depth effects.

We examined whether a pictorial depth illusion influences the manual pursuit of a moving dot to the same extent that it influences the dots apparent displacement. Fourteen subjects performed two tasks. In one case, they used their unseen hand to track a ...

Startle magnitude and prepulse inhibition: effects of alcohol and attention.

BACKGROUND: Previous studies of the effects of attention on prepulse inhibition (PPI) have not accounted for the effects of attention on control (i.e. pulse alone) trials. In addition, there have been no studies of the effects of alcohol on the ...

Motion coherence thresholds in infants--different tasks identify at least two distinct motion systems.

Optokinetic nystagmus (OKN) can be demonstrated from birth, but behavioural discrimination tasks such as habituation and preferential looking do not reveal any sensitivity to motion direction until a few weeks of age. This study compared coherence ...

Factors associated with fatal and injurious car crash among learner drivers in New South Wales, Australia.

This exploratory study investigated factors associated with car crash injury among learner drivers across difference ages by using data routinely collected by the NSW police. The results obtained indicated that some factors are commonly associated with ...

Attention and movement-related motor cortex activation: a high-density EEG study of spatial stimulus-response compatibility.

Visual spatial attentional activation of motor areas has been documented in single cell neurophysiology and functional imaging studies of the brain. Here, we investigate a candidate event-related brain potential representing visuospatial attentional ...

Switching between tasks of unequal familiarity: the role of stimulus-attribute and response-set selection.

It has been reported that it is harder to switch to a strong, well-practiced task from a weaker, less-practiced task than vice versa. Three experiments replicated this surprising asymmetry and investigated how it is affected by a reduction in ...

Functional MRI studies of human visual motion perception: texture, luminance, attention and after-effects.

Motion of an object is thought to be perceived independently of the objects surface properties. However, theoretical, neuropsychological and psychophysical observations have suggested that motion of textures, called second-order motion, may be processed ...

Top-down attentional processing enhances auditory evoked gamma band activity.

In contrast to animal studies, relatively little is known about the functional significance of the early evoked gamma band activity in humans. We investigated whether evoked and induced 40 Hz activity differentiate automatic, bottom-up aspects of ...
