Lecture 8

Question 0

Sequential grouping

Answer 0

Spectral
Intensity
Spatial  
CONTINUITY.
Any discontinuity and we may hear a seperate stream.

Question 1

Concurrent grouping

Answer 1

Events fused togethor

Question 2

Frequency pitch streaming

Answer 2

Dissonance and tonal space separation. Clear up melody

Question 3

Pitch space if large enough creates two streams

True false

Answer 3

True

Question 4

Frequency separation really small.

Answer 4

Always hear as one melody

Question 5

Temporal fission perceptual boundaries.

Answer 5

Red yellow blue.
Red two streams, fast tempo with large frequency range, ambiguous slower.
But
Boundary, small frequencies always easy to hear togethor

Question 6

What happens of smaller idea inside largerd?

Basilar membrane

Answer 6

Creates two higher streams

Question 7

What is the effect of connectedness on streaming?

Answer 7

More you integrate faster, glissando to help connect like picture music.
If not connected, slower much hRder to segregate.

Question 8

I synchronous cannot be heard if octave used, but seperate streams can be
True false

Answer 8

True

Question 9

Framing effects. Melody presented before finding it in mess, with differcing frequency between target and distractor.

Answer 9

Seperates in pitch space increases, identification increases no matter condition.
Melody presented first easier to identify, then to try and match.

Question 10

Pitch is more important than content.

Answer 10

Crossing ears scales

Question 11

Effects of intensity

Answer 11

A louder than b and slow tempo, two streams, rolled effect at faster tempi. Continuity…? At one end b is masked by A. Sequential masking. Close togethor in time.

Question 12

Concurrent and sequential organization.

Answer 12

Sequential more important than concurrent.

Question 13

Spectral effect?q

Answer 13

Timbre even if close in register I easier to segregate. But needs to have many different harmonics. There is degree of difference in timbre too.

Question 14

Target with distractor melody?

Answer 14

Timbre different, means easier to identify after., not before like the other experiment with just frequency.

Question 15

Moving in timbre space with melody? How easy to hear

Answer 15

Easy to hear if timbre is similar and then can seperate into two streams.

Question 16

What happens to the temp when the melodies are seperates from one another by frequency?

Answer 16

The tempo, is slower because the brain perceives them individually rather than fused.

Question 17

Streams are independant of one another this means…

Answer 17

When a melody is interspersed with another even if rhythm is different we cannot hear it. Ales rhythm, can be integrated or segregated.
That’s why alternating registers played fast create two streams

Question 19

Can concurrent and sequential things compete.

Answer 19

Yes

Bregman 4 pitches

Question 33

Effects connectedness on streaming

Answer 33

In
an
alternaAng
sequence
of
tones,
parAal
or
complete
transiAons
that
indicate

where
the
next
tone
will
be
in
frequency,
reduce
the
percepAon
of
segregaAon
and

increase
the
percepAon
of
integraAon.
The

(1978).
In

the
