Q

What is the hypothesised and actual perception of phonemes ‘ba’ and ‘pa’

A

-Hypothetically, we would expect a gradual shift from ‘ba’ to ‘pa’. Actual perception is categorical.

-Hypothetically, adults should be able to discriminate between each VOT. There is actually an abrupt shift typically at about 20-25 ms.

Q

Give 2 key points about The McGurk Effect

A

1) McGurk effect is an example of how 1 sensory modality can influence another (hearing)

2) Speech production is a multi-modal process; not only based on auditory but also visual cues

27
Q

Give 3 points for why context is important for word recognition

A

1) Computer generated novel sounds that fell between /g/ and /k/ (Ganong, 1980) - folowed by ift -> gift, iss -> kiss

2) Speech is full of hesitations, sloppy word productions etc.

3) 47% recognition of isolated words vs 100% recognition within context of original conversation (Pollack & Pickett, 1964)

28
Q

In Pollack and Pickett’s (1964) study, what was the recognition percent for isolated words

A

47%

29
Q

In Pollack and Pickett’s (1964) study, what was the recognition percent for words within context of original conversation

A

100%

30
Q

What movement does the production of speech involve?

A

Fine control of the vocal tract to shape the sound wave to convey particular meaning

31
Q

What does perceiving speech involve?

A

‘Reconstructing’ the meaning from the sound wave

32
Q

Give 4 sources of information that help us to ‘reconstruct’ the meaning from a sound wave to perceive speech?

A

1) Key clues in the wave

2) Knowledge of language

3) Contextual cues

4) Multimodal sources of information including visual cues

33
Q

Simply put, what does the Communication model that turns ideas into air and back again involve?

A

Cognition - Speech Production, Air movement, Cognition - Speech Perception

34
Q

How many key procedures to investigate speech perception in infants are there?

A

3

35
Q

Outline the 3 procedures/methods to investigate speech perception in infants

A

1) High amplitude sucking

2) Head turn preference

3) Preferential looking

36
Q

How does high amplitude sucking investigate speech production in infants?

A

Rate of sucking increases when new sound is detected, then slows down again if sound is repeated

37
Q

How does head turn preference investigate speech perception in infants?

A

If infants turn their head or longer (or shorter) to 1 type of stimulus compared to another, then they must be able to perceptually distinguish them (requires being able to hold head up)

38
Q

How does preferential looking investigate speech production in infants?

A

If infants look for longer (or shorter) to 1 type of stimulus compared to another whilst hearing the names of the stimulus (e.g. Dad), then they must recognise the name

39
Q

Which of the 3 methods would you use to conduct the following experiment?: You are interested in how long 12 month olds pay attention to novel and familiar words

A

Head turn

40
Q

Which of the 3 methods would you use to conduct the following experiment?: You are interested in whether 2 month olds can tell the difference between changing speech sounds

A

High amplitude sucking

41
Q

Which of the 3 methods would you use to conduct the following?: You are interested in whether 6 month olds understand the meaning of different words

A

Preferential looking

42
Q

Which method did Eimas et al. use in their 1971 language learning study?

A

High amplitude sucking

43
Q

What does research by Eimas et al. (1971) tell us about language learning?

A

Infants as young as 1 month old could tell the difference between consonants ‘ba’ and ‘pa’

44
Q

What is a criticism of Eimas et al’s (1971) study?

A
  • Phonemes vary between different languages. E.g. ‘‘ba’ and ‘pa’ are common to English but are less common in other languages
  • Therefore, this ability to distinguish between phonemes language specific
45
Q

According to categorical perception, are phonemic categories language specific?

A

Yes

46
Q

What are English versus Hindi phonemic categories?

A
  • /d/ (alveolar) vs /d/ (retroflex)
  • /t/ (alveolar) vs /t/ (retroflex)
47
Q

When are infants sensitive to all categorical boundaries?

A

In the first 6 months

48
Q

When do infants become sensitive only to their native categories?

A

By 12 months

49
Q

What would happen if infants had to rely on being taught individual words?

A

Their vocabulary would be a fraction of what it actually is

50
Q

Simply put, how does language emerge?

A

Out of ‘basic’ processes of movement and [perception

51
Q

Who conducted researched into the emergence of language, looking at whether production patterns influence the processing of prelinguistic children?

A

DePaolis, R., et al. (2011)

52
Q

What is the first step towards language emergence within infants?

A

Babbling

53
Q

What are 4 key things about babbling in terms of the emergence of language?

A

1) It is non-linguistic (not really ‘speaking’)

2) The emergence of stable, adult-like syllables occurs around 6-8 months

3) There are both universal features and individual differences

4) It is shaped to some degree by ambient language

54
Q

What link did DePaolis, R., et al. (2011) find?

A

Accuracy of spoken words are related to the number of words in child’s ‘lexicon’

55
Q

What does the production-perception loop involve, and what link does it show?

A

When infants hear (recognises) sounds in adult speech corresponding to their own babbling, they already ‘know’ how to produce those sounds, so their first words are pretty accurate (e.g. “papa”, “mama”) -> shows link between

56
Q

How many language development milestones are there?

A

5

57
Q

Give the ages of the 5 language development milestones

A

1) 0-5 months
2) 6-12 months
3) 12-18 months
4) 18-48 months
5) > 48 months

58
Q

What is the 1st language development milestone?

A

0-5 months: Smiles, coos (aah, ooh, grr), makes different sounds to interact

59
Q

What is the 2nd language development milestone?

A

6-12 months: Recognition of simple words, babbling, production of first words

60
Q

What is the 3rd language development milestone?

A

12-18 months: Understanding 140-190 words, production of 75-122 words

61
Q

What is the 4th language developmental milestone?18

A

18-48 months: Vocabulary spurt, basic grammar, increasingly complex sentences, understanding of more abstract concepts

62
Q

What is the 5th language developmental ilestone?

A

> 48 months: Figurative language, combination of sentences, rhymes, takes listener’s perspective

63
Q

What perceptual consequences does movement have?

A

changes in movement, changes in air, changes in meaning

64
Q

How is the auditory system involved in perception?

A

The auditory system extracts patterns from sound
