Q

what’s the location of the primary auditory cortex associated with tone chroma

A

posterior

21
Q

define the effect of missing fundamental

A

even after the removing the fundamental frequency, we can still perceive the same pitch we would have

22
Q

what happens when there are damages to the PAC

A
  1. bilateral lesions : increase in thresholds for judging if two sounds have the same pitch
  2. disrupts the ability to integrate the fundamental and harmonic frequencies into a whole
23
Q

define residue pitch

A

ability to integrate the fundamental and harmonic frequencies into a whole

24
Q

what are the 2 distinct ways we can process regularities

A
  1. based on regularities essential for acoustic properties
  2. based on regularities that have already been learned
25
Q

what is an example of a statistical regularity

A

a q is usually always followed by a u in english language

26
Q

echoic memory is a part of what bigger type of memory

A

sensory memory

27
Q

true or false - echoic memory is a buffer that hold information for 2-3 minutes

A

false - only for a few seconds

28
Q

what did Simola, Jaramillo, Naantanen and Winkler argue

A

argued that echoic memory stores physical and abstract features of sounds that have just been heard

29
Q

how are statistical mismatch negatavities produced

A

when there are violations of expectations for local dependencies

30
Q

______ refers to statistical regularities underlying the arrangement of sounds

A

local dependencies

31
Q

what is phMMN

A

MMN based on physical features

32
Q

what is the main difference between local and nonlocal dependencies

A

nonlocal -> happens over a longer period of time

33
Q

give an example of violating the nonlocal dependencies

A

starting with a tonic (chord 1) and ending with a supertonic (chord 2)

34
Q

when we say music has a hierarchical structure, what does this mean

A

both local and nonlocal dependencies are relevant

35
Q

ERANs are produced by what

A

violations of nonlocal dependencies

36
Q

what does ERAN stand for

A

early right-anterior negativity

37
Q

define latency

A

refers to when the ERP component actually emerges

38
Q

define amplitude

A

refers to the changes in the magnitude of the electrical activity

39
Q

______ is the anticipation of specific events in familiar event structure

A

veridical expectations

40
Q

warning the participants about the irregular chord affected latency/amplitude

A

latency -> amplitude was unaffected

41
Q

when does the ERAN emerge (age)

A

2 and a half year old

42
Q

in what case is the ERAN absent in people

A

people who have amusia/ linguistic impairments

43
Q

which two areas, involved in music syntatic processing, overlap with Broca’s area

A

pars opercularis and inferior frontal gyrus

44
Q

the inferior frontal gyrus primarily processes non local or local dependencies

A

nonlocal

45
Q

which two areas, involved in music syntactic processing, overlaps with the PAC

A

premotor cortex and superior temporal gyrus

46
Q

LAN is associated with what type of violations

A

linguistic

47
Q

what does LAN stand for

A

lateral anterior negativity

48
Q

true or false - there is some interactions between ERAN and LAN

A

true
