Attention

Question 1

theories of Consciousness, what does it utilize, what does it organize?

Answer 1

Awareness

• organize sensory and motor information
• language

Question 2

theories of Attention, what does it utilize, what does it organize?

Answer 2

Selective awareness
Cognitive function that exerts control on other processes
-enhancement or direction of more resources

Question 3

Attention is operationalized by what?

Answer 3

Task requirements

Question 4

Kinds of attention
What is Alerting attention?

Operationalized and brain area

Answer 4

Noticing

Locus Coeruleus

Question 5

Kinds of attention
What is Sustained/Divided attention?

Operationalized and brain area

Answer 5

Focus (moment to moment)

DLPFC

Question 6

Kinds of attention
What is Executive control (Shifting, inhibiting, WM) attention?

Operationalized and brain area

Answer 6

Shifting = Orienting
Dorsal orienting networks: FEF –> Intraparietal sulcus

Inhibiting = Selective
Ventral orienting network VFC –> TPJ

Updating WM = Task set
Cingulo-opercular

Question 7

What part of the brain is reward

Answer 7

Pulvinar (reroute/integration

Question 8

What is the method of conjunction search?

dependent on what?

Answer 8

Sustained and selective

• it is dependent on number of different features
• integration across V1-V5
• pop out effect

Question 9

Methods of selective attenction depends on what?

Answer 9

Experties

• Selective (Bottom up)
• fine tuning of relevant features
• more nuanced (hight discrimination)
• selective as interest (top down)

Question 10

In selective attention what does the pulvinar act as?

Answer 10

Glue

• binding problem
• hollictic

Question 11

What are the methods of divided attention?

Answer 11

Selective attention

• inhibition (ignoring) of irrelevant stimuli
• sensory:local inhibitory interneurons
• top down control : VLPFC (synchrony)

Question 12

Disruptions in attention

Detection

Answer 12

Inattentional blindness
-restricted attentional field

change blindness
-heuristics

Question 13

What is the attentional blink?

What are the components of it?

Answer 13

Sensory “memory” (550ms)

Priming, masking, attentional blink

Question 14

Attentional blink

Priming

Answer 14

7 Diamonds was easily seen in the “too fast” attempt

Question 15

Attentional blink

Masking

Answer 15

Face cards are used as masks to interfere with previous sensory processing

Question 16

Attentional blink

Answer 16

2 hearts creating the first attentional blink
-processing capacity (mask cards create next)
primary and recency effects (memory effects)

Question 17

Disorders in attention

Answer 17

Sensory neglect

• perceptual adaptation
• prisms and effortful learning

Question 18

Consciousness is defined as what in terms of attention?

Answer 18

Level of responsiveness of the mind to sensory impressions

Question 19

What is the process, Brain region and behaviour of Arousal?

Answer 19

Reticular activating system

coma

Question 20

What is the process, Brain region and behaviour of perception

Answer 20

Thalamus

Dissociative, Vegetative state

Question 21

What is the process, Brain region and behaviour of Attention?

Answer 21

VLPFC

Selection

Question 22

What is the process, Brain region and behaviour of Short term memory

Answer 22

Sensory area

Synchrony (binding)

Question 23

Attention-consciousness thories

Answer 23

Synchronization
cyclical, timed patterns of tonic (continuous) and phasic (burst) responses
-timing:neural resting firing-rate
-singal-to-noise ratio (comparing activation)

Question 24

Attention-consciousness theories

Within networks

Answer 24

Stimulus (sensory) features

Question 25

Attention-consciousness theories

Between networks

Answer 25

Feature integration (binding problem)

Motor representation
