S2W6 - (1) Multisensory Perception

Question 1

Senses with a close field of operation

Answer 1

smell, taste, touch

Question 2

Senses whose operation works at a distance

Answer 2

sight, sound

Question 3

Statistical facilitation

Answer 3

independent parallel processing of multiple senses; the first sense to produce an answer is used; main effect

Question 4

Neural Coactivation

Answer 4

integrated signals of multiple senses construct a better concept of the stimulus than the sum of its parts; interaction

Question 5

Botton-Up and Objective Factors of Integration

Answer 5

temporal and spacial coincidence, temporal patterning

Question 6

Top-Down and Subjective Factors of Integration

Answer 6

stored knowledge, context, recent experience, expectation, attention

Question 7

Multimodal Brain Areas

Answer 7

superior temporal sulcus, superior colliculus, inferior colliculus

Question 8

Spacial Rule of Multisensory Enhancement

Answer 8

multisensory stimuli must occur in the same space

Question 9

Principle of Inverse Effectiveness of Multisensory Enhancement

Answer 9

enhancement is greater for weak stimuli than strong;
e.g. you don’t need to hear the tiger to be afraid if its standing in clear view, but you do need to hear it if its in the tall grass that obscures your vision

Question 10

Superior Colliculus Function

Answer 10

motor actions guided by multisensory stimuli; primarily visual, auditory, and somatosensory; reflective orienting to stimuli (bottom-up); multiple sensory input preference

Question 11

Superior Temporal Sulcus Function

Answer 11

AV speech processing and combined inputs; McGurk effect
