Corbetta & Shulman’s review suggests which is involved in detection of salient unexpected events?
A. a right lateralized ventral frontoparietal system
B. a left lateralized dorsal frontoparietal system
C. a left lateralized ventral frontoparietal system
D. a right lateralized dorsal frontoparietal system
A. a right lateralized ventral frontoparietal system
An experimental strategy Corbetta and Shulman describe for investigating ‘attentional sets’ involves:
A. Requiring inhibition of the response to the target on a subset of the detection trials in an attention task.
B. Using warning signals before target presentation in attention tasks.
C. Creating a delay in time between the stimulus cue that invokes the ‘attentional set’ and the onset of the target.
D. Creating response conflict in the task demands of an attention task
C. Creating a delay in time between the stimulus cue that invokes the ‘attentional set’ and the onset of the target.
Corbetta and Shulman describe 2 kinds of ‘attentional set’. Which of the following is a likely outcome of a ‘perceptual set’?
A. more rapid detection of a target when one knows in advance something about the nature of the response required to confirm detection.
B. more rapid response selection when one knows in advance something about the nature of the response required.
C. more rapid response selection when one knows in advance something about the target cue’s features or attributes
D. more rapid detection of a target when one knows in advance something about its features or attributes.
D. more rapid detection of a target when one knows in advance something about its features or attributes.
In a simple spatial cueing task described by Corbetta and Shulman, which cortical areas exhibited a sustained response during the delay while the participant was waiting for the target?
A. Lateral occipital cortex and ventrolateral prefrontal cortex
B. Frontal eye field area and intraparietal cortex
C. Intraparietal cortex and lateral occipital cortex
D. Lateral occipital cortex and frontal eye field area
B. Frontal eye field area and intraparietal cortex
The results from the attention study reviewed by Corbetta & Shulman, in which participants had to detect the direction of motion of a few coherently moving dots in a dot array (after a delay) showed:
A. That extrastriate visual cortex and frontal eye field areas are active during ‘attentional sets’ for motion direction.
B. That intraparietal cortex and frontal eye field areas are active during ‘attentional sets’ for nonspatial features as well as spatial locations.
C. That intraparietal cortex and frontal eye field areas are involved in detection of motion in dot arrays.
D. That temporoparietal junction and ventrolateral prefrontal cortex are active during ‘attentional sets’ for nonspatial features as well as spatial locations.
B. That intraparietal cortex and frontal eye field areas are active during ‘attentional sets’ for nonspatial features as well as spatial locations.
Corbetta and Shulman point out that activation of intraparietal cortex and frontal eye fields by cues that invoke attentional sets are observed:
A. Only for attentional sets that enhance performance in spatial location tasks.
B. Only for attentional sets that enhance perceptual processing in attention tasks.
C. Only for attentional sets that enhance response selection or execution in attention tasks.
D. For attentional sets that enhance both perceptual and response processing in attention tasks.
D. For attentional sets that enhance both perceptual and response processing in attention tasks.
Corbetta and Shulman point out that the dorsal frontoparietal system for establishing attentional set overlaps with the working memory system. When is working memory the most similar to the ‘attentional set’ functions described in this review?
A. When the items that must be maintained during the delay are numerous or complex.
B. When the task involves a significant degree of conflict between competing responses.
C. When the items that must be maintained during the delay are simple and few.
D. When the task requires significant manipulation of the material that is maintained during the delay.
C. When the items that must be maintained during the delay are simple and few.
Corbetta and Shulman point out that activity in the dorsal frontoparietal ‘attentional set’ system appears to be modulated by ‘salience’. Which of the following could be described as emotional salience?
A. Relatedness to task goals
B. Reward value in the task
C. Previous significance in the task
D. Stimulus novelty
B. Reward value in the task
The ventral frontoparietal system of Corbetta & Shulman IS NOT activated during which of the following conditions?
A. On detection of low-frequency stimuli.
B. On detection of an unexpected or startling event.
C. After a cue signaling the direction of motion of an upcoming target.
D. By a target after a cue directing attention elsewhere.
C. After a cue signaling the direction of motion of an upcoming target.
