Attention

Question 1

Bottlenecks

Answer 1

Only a limited amount of information can be attended to at any time

Question 2

Divided attention

Answer 2

Challenging to maintain when tasks require conscious attention

Question 3

color and shape

Answer 3

Visual cortical area v4, inferior temporal cortex, and other visual areas of the temporal lobe

Question 4

direction of motion

Answer 4

MTA and MST

Question 5

speed of motion

Answer 5

medial temporal area

Question 6

Attention effects on neuronal response in parietal cortex

Answer 6

Enhanced neuronal responses in the posterior parietal cortex if followed by a saccade to the target
* Attention changes location prior to an eye movement
* The enhancement is spatially-selective
* The enhancement is due to attention shift rather than premotor signal related to the eye movement

Question 7

• Receptive field:

Answer 7

An area in which stimulation leads to the response of a partciular sensory neuron

Question 8

FEF neurons control…

Answer 8

FEF neurons control
saccadic eye movements to
corresponding motor fields

Question 9

• The frontal eye fields
  (FEF)

Answer 9

an area of the frontal
cortex with direct
connections with many
brain areas involved in
attention

Question 10

Parietal Cortex Damage in Hemispatial Neglect Syndrome

Answer 10

Hemispatial neglect is often associated with right hemisphere damage of the parietal cortex,
suggesting right hemispheric laterization for awareness.
