Language Flashcards
Definitions of language
Language is species-specific only humans acquire it although other animals can communicate
Language is species-universal - all humans acquire language
Using the finite set of words in our vocabulary, we can put together an infinite number of sentences
Limitations to acquiring language
Critical period
Cognitive impairment
Highly abnormal environmental conditions
Two main components of language
Language comprehension: understanding what others say
Language production: Refers to actually speaking (or writing) to others
Language requires four competencies
phonological development
semantic development
syntactic development
pragmatic development
Phoneme definition
The individual elements of sound that make up words
Number of phonemes in English language
40
Phonological development definition
the acquisition of the sound system of the language the child is exposed to
Prosody
the particular rhythm, melody and intonation pattern used when speaking a language
Morpheme definition
the smallest part of a word with meaning
Morphological rules
a set of rules that specifies how morphemes combine to form words
Semantic development
the acquisition of meaning in a language, including lexical development (word learning)
Syntax definition
A set of rules that specifies how words can be combined to form sentences
In English word order also determines meaning
Syntactic development
the acquisition of the grammar of a language
Pragmatic definition
• Sarcasms, irony, commands, voice change, etc
Pragmatic development
the acquisition of how a language is used in society
Characteristics of motherese

emphasises word and phrase boundaries making it easier for the baby to segment words from the continuous speech
keeping the child’s attention
word identification
Motherese real name
Infant-Directed Talk/Speech (IDT/IDS)
Fernald & Mazzie (1991): Kelly’s New Clothes
• Mothers of 14 months old babies used prosodic emphasis to teach new words.
Words (clothes) received primary stress 76% to babies and 42% to another adult.
- When the same clothing was mentioned again it was highly stressed 70% to babies but 20% to adults.
- The clothes located at the end of a sentence 75% for babies, 53% for adults.
Werker, Pegg & McLeod (1994)
• Infants prefer IDT/IDS than other type of speech.
Chinese and American infants listened to a Chinese mother when talking to a baby (motherese) or to an adult
Results: all babies prefer to listen to mother talking to a baby (even in their non-native language) than talking to an adult.
Golinkoff, Alioto, & Hirsh-Pasek (1996)
Infants learn more new words in a foreign language when they are presented in IDT/IDS than in normal speech
Thiessen, Hill & Saffran (2005)
Infant-directed speech facilitates word segmentation
Participants: 50 infants aged 7.5 to 8.5 months
Material: 4 non-word sentences
Exposed to either IDS or normal speech
Results: Infants exposed to IDS were able to segment the speech and the control group couldn’t
Development of babbling
- 0-2 month - comfort sounds (aaaa)
- 2-3 month - cooing (gaaagaa)
- 4-6 month - squalls, growls, whispers (called marginal babbling)
- 6-10 month - infant babble. consonant-vowel sounds (mamama)
Kuhl, Tsao, and Liu (2003)
9mo American infants with Mandarin adult.
Group 1: play sessions with adult, experienced 5 hours of Mandarin
Group 2: video of session received identical exposure to Mandarin
Group 3: exposure to only audio information.
Results: exposure to auditory information isn’t sufficient for learning of phonology - need social interaction
