Attention Networks Flashcards
(24 cards)
The lobes of the cortex that are disproportionately involved in Posner & Rothbart’s attention networks are:
frontal and parietal
The lobes of the cortex that are disproportionately involved in Posner & Rothbart’s attention networks are:
frontal and parietal
The three primary attentional functions that are the focus of Posner & Rothbart’s review are:
alerting, orienting, and executive
According to the Posner and Rothbart review, which of the following is Hebb’s “cell assembly theory”:
Reverberatory activity in a set of interconnected neurons give rise to mental activity
The assertion by Hebb, a version of which is now referred to as Hebb’s Law, is:
The more often a neuron stimulates a connected neuron (B) that immediately fires, the more efficient A becomes at stimulating B.
Posner and Rothbart list four investigative approaches that they feel will provide greater insight into the nature of attention. Which of the following IS NOT among the approaches they listed?
Study of effects of psychiatric disorders on attention

Study of effects of psychiatric disorders on attention
In attention experiments, drugs that block norepinephrine:
Reduce the effect of warning signals on reaction time and do not affect orientation to the target location
Match to the most appropriate attention network - Achieving and maintaining sensitivity to incoming stimuli:
Alterting
An experimental manipulation for the investigation of the alerting system is:
the use of warning signals
According to Posner and Rothbart, which of the following is analogous to the lateral intraparietal area implicated in spatial orienting in monkeys:
Superior Parietal Lobe
According to Posner and Rothbart, which of the following is true of orienting in attention?
It is the selection of information from sensory input and aligning attention with a source of sensory signals either overtly or covertly
Which of the following is implicated in processing of salient information in an unattended location (to which attention must be re-oriented)?
Temporoparietal Junction
An experimental manipulation used by Posner et al. for the investigation of the orienting system of attention is:
The use of spatial cues
In attention experiments, anticholinergic drugs:
Do not reduce the effect of warning signals on reactions time and slow orientation to the target location
In attention experiments, anticholinergic drugs:
Do not reduce the effect of warning signals on reactions time and slow orientation to the target location
As reviewed by Posner and Rothbart, in selective attention paradigms with stimuli in multiple sensory channels, functional connectivity increases between the selected sensory modality and which of the following?
Anterior Cingulate
Which of the following have been implicated in resolution of the kind of response conflict experienced on the Stroop task:
anterior cingulate and ventral prefrontal cortex
T/F: Executive Attention involves mechanisms for monitoring and resolving conflict among thoughts, feelings, and responses.
True!
An experimental manipulation for the investigation of the executive attention system is:
Conditions which increase response conflict
An experimental manipulation for the investigation of the executive attention system is:
Conditions which increase response conflict
Are these properly matched? Alerting network - modulated by norepinephrine
Yes!
Are these properly matched? Orienting network - experimentally manipulated with location cues
Yes!
Are these properly matched? Executive network - manipulated with warning signals
No
