Attention Regulation Flashcards
Which is involved in detection of salient unexpected events?
A right lateralized ventral frontoparietal system
What experimental strategy is used for investigating attentional sets?
Creating a delay in time between the stimulus that invokes the attentional set and the target onset.
What kind of attentional set that is likely to produce a perceptual set?
More rapid detection of a target when one knows in advance something about its features or attributes
The study in which participants had to detect the direction of motion of a few coherently moving dots in a dot array showed:
That intraparietal cortex and frontal eye field areas are active during attentional sets for nonspatial features as well as spatial locations
The _____________ cortex shows a transient response to an arrow direction stimulus.
lateral occipital
The fontal eye field and intraparietal cortexes show what in an attention task?
A sustained response during the delay, while a participant is waiting for the target
The fontal eye field and intraparietal cortexes show what in an attention task?
A sustained response during the delay, while a participant is waiting for the target
Which parts of the brain have been observed for attentional sets that enhance perceptual and response processing in attention tasks?
The intraparietal cortex and frontal eye fields
When is working memory most similar to the ‘attentional set’ functions described in this review?
When the items that must be maintained during the delay are simple and few.
When is working memory most similar to the ‘attentional set’ functions described in this review?
When the items that must be maintained during the delay are simple and few.
The working memory system over laps with which other system?
Dorsal frontoparietal system
The working memory system over laps with which other system?
Dorsal frontoparietal system
The salience is modulated by activity in which system?
Dorsal frontoparietal ‘attentional set’ system
Reward value in the task could be used to describe what?
Emotional salience
T/F: the ventral parietal system is activated after a cue signaling the direction of motion of an upcoming target.
False!
