Relating the mechanisms of orienting and alerting
D Fernandez-Duque, MI Posner - Neuropsychologia, 1997 - Elsevier
Cues provide two types of information: information about where the target will occur and
when it will occur. We hypothesized two underlying processes related to cues, orienting (to …

Auditory sustained attention is a marker of unilateral spatial neglect
IH Robertson, T Manly, N Beschin, R Daini… - Neuropsychologia, 1997 - Elsevier
The relationships between performance on a non-spatially-lateralized measure of sustained
attention and spatial bias on tests sensitive to unilateral neglect were considered in a group …

Alteration of brain noradrenergic activity in rhesus monkeys affects the alerting component of covert orienting
EA Witte, RT Marrocco - Psychopharmacology, 1997 - Springer
Experiments were conducted to elucidate the role of the noradrenergic neurotransmitter
system in arousal and the orienting of attention. Rhesus monkeys were trained to perform a …

The neural correlates of the noradrenergic modulation of human attention, arousal and learning
The prefrontal cortex has been suggested as a site of action for the noradrenergic
modulation of cognition. In healthy volunteers attentional deficits can be induced by the α2 …

Caffeine and the common cold
An experiment was carried out to determine whether caffeinated and decaffeinated coffee
removed the malaise (reduced alertness, slower psychomotor performance) associated with …
