Question
What are the stages of the 3 stage model?
Answer
  • Shape representation
  • Local features
  • Object representation
  • Orientation selectivity
  • Movement selectivity
  • Colour selectivity
  • Feature recognition

Question 2

Question
What are the features of Apperceptive agnosia?
Answer
  • Deficient shape representation
  • Can't copy or match visual stimuli/shapes
  • Impairments occur at stage 2
  • Is able to copy stimulus but not name them
  • Deficient object representation
  • Impairments at stage 3

Question 3

Question
What are the characteristics of Associative agnosia?
Answer
  • Can copy stimuli but cannot recognise them
  • Deficient object representation
  • Impaired at stage 3
  • Can't copy or match stimuli/shapes
  • Impairments at stage 2
  • Deficient shape representation

Question 4

Question

Answer
  • Proximity
  • Similarity
  • Symmetry
  • Continuation
  • Closure
  • Common fate
  • Current mood
  • Shape priming
  • Adaptation

Question 5

Question
In image based segmentation, what are the texture-based segmentation strategies?
Answer
  • Proximity
  • Similarity
  • Common motion
  • Skylines

Question 6

Question
Image-based contour integration [blank_start]Collector units:[blank_end] Local edge responses feed forward to neurons that collate them, those of which have their output signals representing a contour. [blank_start]Extrastriate Feedback:[blank_end] Feedback from high cortical areas modulate the activity in V1 cells, increasing responses to contours. [blank_start]Cooperative interactions:[blank_end] Edge responses are propagated laterally, producing mutual facilitation when neurons nearby are also active.
Answer
  • Collector units:
  • Extrastriate feedback:
  • Cooperative interactions:

Question 7

Question
Which of the following are extrinsic factors that are apart of object recognition?
Answer
  • Viewpoint
  • Lighting
  • Occluding objects
  • Background
  • Physical features of the object
  • External rewards for completing tasks

Question 8

Question
Tarrs multiple view recognition theory proposes that...
Answer
  • To recognise an object from differing viewpoints we must have already stored how it looks from those viewpoints.
  • We can recognise an object from differing viewpoints after seeing a single photo of that object.
  • If multiple people have viewed an object once then they can all recognise that object from any viewpoint.
  • From one viewpoint we can imagine what the object looks like from every other viewpoint.

Question 9

Question
The McGurk effect is most apparent when the stimuli are presented...
Answer
  • At approximately the same time
  • With one occurring about 150ms after the other
  • When one occurs 250ms after the other
  • Regardless of how much time is between the 2 stimuli

Question 10

Question
The McGurk effect is increased if the [blank_start]auditory stimulus[blank_end] has noise added to it.
Answer
  • auditory stimulus
  • visual stimulus
  • occulomotor stimulus
  • video

Question 11

Question
Unrelated auditory stimuli affecting our response times to a visual target is an example of?
Answer
  • Population Coding
  • Cross-modal Cueing
  • Working memories effect on sound interference
  • Attentional Distraction

Question 12

Question
The ventriloquist effect describes how...
Answer
  • Vision can affect our auditory localisation
  • Jeff Dunham performs his comedy
  • Dolls in horror movies move on their own
  • The McGurk effect works

Question 13

Question
When a bimodal neuron is stimulated by both its preferred stimuli, the resulting firing rate is [blank_start]superadditive[blank_end].
Answer
  • superadditive
  • additive
  • summation
  • synthetic
  • Subadditive

Question 14

Question
What are the factors that are involved in determining which stimulus responses are binded together?
Answer
  • Temporal synchrony
  • Spatial correspondence
  • Synaesthetic congruency
  • Similarity of stimuli
  • Current working memory load
  • A persons previous experiences

Question 15

Question
The bandwidth of time which multimodal interactions are more likely is the [blank_start]temporal binding window[blank_end], this window is [blank_start]asynchronous[blank_end].
Answer
  • temporal binding window
  • temporal tolerance
  • temporal synchrony
  • asynchronous
  • synchronous
