10-1

Question 1

divided attention

Answer 1

multitasking
* Ability to focus on multiple forms of sensory information
* Can be investigated in an experimental condition

Question 2

dual-task paradigm

Answer 2

• Primary task & secondary task
• Measure performance on both
• Can be manipulated with different
  interventions
  **performance of both tasks will be worse
  than if performed separately

Question 3

Selective attention

Answer 3

• Ability to focus attention on one specific task

Question 4

Exogenous

Answer 4

external, reflexive
* Focus on objects/stimuli that stand out

Question 5

Endogenous

Answer 5

internal, voluntary
* Incorporates intention, goal orientation, previous knowledge

Question 6

Blindness

Answer 6

• Due to attentional demand, can
  experience types of “blindness” to your
  environment

Question 7

inattentional Blindness

Answer 7

miss something

Question 8

Change Blindness

Answer 8

don’t notice something
has changed

Question 9

Primary Visual Cortex (V1)

Answer 9

Located within the Occipital Lobe
V1 is arranged “retinotopically”
* Specific groups of neurons
represent/respond to specific parts
of our visual field
-All visual information passes
through the Lateral Geniculate
Nucleus (within Thalamus)

Question 10

Secondary Somatosensory Cortex

Answer 10

-Involved in DORSAL STREAM
* Located in the posterior parietal lobe
* In complex movement sequences, role in:
* Confirming which movements have already
taken place
* “Deciding” what movements come next

Question 11

V1

Answer 11

• Receives visual signal from eyes
• Passes through visual association areas
• Relays information to two primary areas

Question 12

Inferotemporal Lobe

Answer 12

involved in ventral stream
* Involved in visual memory (input from the hippocampus)
* Role in object recognition
* Helps understand complex stimuli like faces and scenes

Question 13

Dorsal Stream

Answer 13

V1  Secondary Somatosensory Cortex
* Object location and motion
* Detecting and analyzing movements
* Spatial awareness and guidance of
action

Question 14

Apraxia

Answer 14

• Damage to the Secondary Somatosensory Cortex
• Movement disorder which impairs the ability to perform tasks
  or movement, especially sequences
• Does not impair ability to plan or execute movements, but
  disrupts how they are performed  leaves movements
  fragmented and confused

Question 15

Ventral Stream

Answer 15

V1  Inferotemporal Lobe
* Object recognition and form
representation

Question 16

Visual Agnosia

Answer 16

• Damage to the Inferotemporal Lobe
• Disorder which impairs the ability to recognize objects
• Does not impair ability to SEE object, but instead to process
  and understand what the object is

Question 17

Prefrontal Cortex:

Answer 17

decision making centre of the brain
* Decide what response you want to have to your environment
* “Should I make response x or response y?”.

Question 18

Prefrontal Cortex projects to the Premotor Cortex

Answer 18

• At this stage we answer:
  What do I need to do in order to
  carry out the chosen response?
• Premotor cortex will:
• help plan movement
• project to other motor areas to
  carry out desired movement
  ** deciding on response and ability to carry out that response are influenced
  by the amount of attention you are paying to the task (limited resource)
