Chapter 9 Flashcards
language
a system for communicating with others using signals that are combined according to rules of grammar and convey meaning
grammar
a set of rules that specify how the units of language can be combined to produce meaningful messages
phoneme
the smallest unit of sound that is recognizable as speech rather than as random noise
phonological rules
a set of rules that indicate how phonemes can be combined to produce speech sounds
morphemes
the smallest meaningful units of language
- content morphemes (ex. cat, dog, take)
- function morphemes serve grammatical functions (ex. and, or, but, when)
morphological rules
a set of rules that indicate how morphemes can be combined to form words
syntactical rules
a set of rules that indicate how words can be combined to form phrases and sentences
deep structure
the meaning of a sentence
surface structure
how a sentence is worded
fast mapping
the fact that children can map a word onto an underlying concept after only a single exposure
telegraphic speech
speech that is devoid of function morphemes and consists mostly of content words
nativist theory
the view that language development is best explained as an innate, biological capacity
language acquisition device (LAD)
a collection of processes that facilitate language learning
genetic dysphasia
a syndrome characterized by an inability to learn the grammatical structure of language despite having otherwise normal intelligence
aphasia
difficulty in producing or comprehending language
Broca’s area
located in left frontal cortex, is involved in production of the sequential patterns in vocal and sign languages
- critical for language production
- Broca’s aphasia: understand language but difficulty with grammatical structure
Wernicke’s area
located in left temporal cortex, is involved in language comprehension (whether spoken or signed)
- critical for language comprehension
- Wernicke’s aphasia: can produce grammatical speech but tends to be meaningless, have difficulty comprehending language
bilingual
- show similar rates of language development when compared to monolingual children
- show greater executive control capacities
- have a later onset of Alzheimer’s
linguistic relativity hypothesis
the proposal that language shapes the nature of thought
concept
a mental representation that groups or categorizes shared features of related objects, events, or other stimuli
family resemblance theory
members of a category have features that appear to be characteristic of category members but may not be possessed by every member
prototype
the “best” or “most typical” member of a category
