Chapter 6 Flashcards
Chomsky spoke about the language
acquisition device (LAD),
which he indicated that children have an innate ability to learn
a spoken language in whatever culture they are born. Every individual is born with
knowledge about the rules that exist within a grammar and with knowledge about possible
exceptions.
Two things promote the language acquisition of a child:
(1) “motherese” or
infant-directed speech (IDS), and (2) a child’s innate tendency to social contact and
attachment.
What is phonological development?
Phonological learning is about the sounds of a language. It consists of two aspects:
1) Learning about certain patterns of sound combinations that are allowed in a certain
language. This allows the brain to make phonological representations of the sound
structure of individual words.
2) Learning to produce these words yourself.
At what age does categorical perception develop, where the sounds that are very similar are no longer heard as B but as P for example.
When children are one month old.

The ability to distinguish phonemes in another language disappears after one year. then it is developed.
Heschl’s gyrus
important for speech production in adults
Broca’s area
is related to the production of speech, repetition in silence, and
short-term memory. This was the only area in children that was sensitive to repetition of
sentences
As well as being
capable of categorical perception, speakers need to be able to recognize a given phoneme
independently of its surrounding phonemes, this is termed phonetic normalisation. Example,
the /d/ sound in the syllables /di/ and /du/ is different acoustically. Mersad and
Dehaene-Lambertz used the mismatch response (MMR) to measure whether infants could
recognize such differences.
They reported that the infants did indeed show a significant
MMR to the change of initial consonant.
difference between monolingual and bilingual kids by looking at a head while talking
Monolingual infants
show an early attentional focus on the eyes when looking at a talking head, and later on
infants shift focus attention on the mouth (at around 8-10 months). The onset of babbling
may create a greater need for motor information about speech. Bilingual infants are beyond
the scope of this book, but are worth mentioning. They are learning two sets of sound
systems, two sets of rules for world order, and two lexicons. They show more attention to the
mouth of a talking face at an earlier age, perhaps this signals an increased need to use
visual cues to articulate in developing two different lexicons.
allophones
Sounds that we would categorise as “B” or “P”, but that are relatively different from the
prototype
The magnet effect
means that sounds that resemble each other are classified in the same
category, and sounds that do not resemble each other are not, even though there may be no
physical difference between these sounds
At what age can children distinguish between two syllables?
10,5 months.
head turn procedure and syllables, conclusion
children look longer at the flashlight when the words are known, but when the last letter differed, they didn’t spot a difference
What are rise times and what happens if you take that out of the speech?
‘Rise times’ are increases in amplitude in the
speech envelope as syllables are produced and are critical cues to local amplitude variations
(which the brain is interested in). For example, if rise times associated with syllable-level
modulations are taken out of speech, adults can no longer comprehend what is being said
(Doelling, Arnal, Ghitza & Poeppel, 2014)
The motor hypothesis
of babbling
states that the rhythm of babbling is determined by the physiological movements
of the jaw.
