Question 1 of 18

1

What is an auditory scene?

Explanation

Question 2 of 18

1

What is auditory scene analysis?

Select one of the following:

  • 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 3 of 18

1

What is simultaneous organisation?

Select one of the following:

  • Extracting individual components of a waveform and "group" ones that originate from same event

Explanation

Question 6 of 18

1

What is the main rule of the Similarity Principle?

Select one of the following:

  • Sounds with similar qualities tend to be percieved as coming from the same source

Question 13 of 18

1

The perceptual organisation of sequential components depends on factors such as what?

Explanation

Question 14 of 18

1

For the principle Closure, what is the main rule?

Select one of the following:

  • 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

Explanation

Question 15 of 18

1

Closure: When sound is interrupted by noise, what are the two ways in which this could be perceived?

Select one of the following:

  • (1) Sound could be perceived as interrupted
    (2) Continuing through the noise

    (2) Continuing through the noise

  • (1) Sound could be perceived as a whole
    (2) Sound could be perceived as two separate sounds

Explanation

Question 16 of 18

1

What is the main assumption of the principle of Good Continuation?

Select one of the following:

  • 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

Explanation

Question 17 of 18

1

What is the main rule of the Figure-Ground Principle?

Select one of the following:

  • 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"

Explanation

Question 18 of 18

1

In the Figure-Ground principle, what happens to the "ground"?

Select one of the following:

  • 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
