A display of multiple sounds from various sources
Question 2
Question
What is auditory scene analysis?
Answer
-
The process of inferring backwards which sounds come from which source in order to build a mental representation of each, when all are received simultaneously
-
The process of inferring backwards which sounds come from which source in order to build a mental representation of each, when all are received sequentially
-
The process of tracking forwards which sounds come from which source in order to build a mental representation of each, when all are received simultaneously
-
The process of tracking forwards which sounds come from which source in order to build a mental representation of each, when all are received sequentially

Question 14
Question
For the principle Closure, what is the main rule?
Answer
-
In ambiguous situations, the missing bits of sound tend to be filled in, resulting in the perception of continuity
-
In ambiguous situations, the missing bits of sound tend to be omitted, resulting in the perception of continuity
-
In ambiguous situations, the missing bits of sound tend to be filled in, resulting in the perception of closed gaps where the missing sound is
-
In ambiguous situations, the missing bits of sound tend to be omitted, resulting in the perception of closed gaps where the missing sound is
Question 15
Question
Closure: When sound is interrupted by noise, what are the two ways in which this could be perceived?
Answer
-
(1) Sound could be perceived as interrupted (2) Continuing through the noise
-
(1) Sound could be perceived as interrupted (2) Sound could be perceived as two separate sounds
-
(1) Sound could be perceived as a whole (2) Continuing through the noise
-
(1) Sound could be perceived as a whole (2) Sound could be perceived as two separate sounds
Question 16
Question
What is the main assumption of the principle of Good Continuation?
Answer
-
Sounds going through simple and smooth changes more likely perceived as from same source, than those with abrupt changes in pitch, loudness or localisation
-
Sounds going through simple and smooth changes less likely perceived as from same source, than those with abrupt changes in pitch, loudness or localisation
-
Sounds going through simple and smooth changes more likely perceived as from same source, than those with abrupt changes in timbre or harmonic qualities

Sounds going through simple and smooth changes less likely perceived as from same source, than those with abrupt changes in timbre or harmonic qualities
Question 17
Question
What is the main rule of the Figure-Ground Principle?
Answer
-
Once all sounds allocated to sources, one will emerge as the "figure" and will be the object of attention, while the rest become the "ground"
-
Once all sounds allocated to sources, one will emerge as the "fundamental" and will be the object of attention, while the rest become the "ground"
-
Once all sounds allocated to sources, one will emerge as the "figure" and will be the only one processed, while the rest become the "ground"
-
Once all sounds allocated to sources, one will emerge as the "fundamental" and will be the only one processed, while the rest become the "ground"
Question 18
Question
In the Figure-Ground principle, what happens to the "ground"?
Answer
-
All "ground" sounds are still available, attention is able to switch back to them at will
-
All "ground" sounds are still available, but attention is not able to switch back to them at will
-
All "ground" sounds become one, attention is able to switch back to them at will
-
All "ground" sounds become one, but attention is not able to switch back to them at will
