Chapter 9: Language and Thought Flashcards
Language
a system for communicating with others using signals that are combined according to rules of grammar and that convey meaning
Grammar
set of rules that specify how the units of language can be combined to produce meaningful messages
3 differences that distinguish human language from other signaling systems
(1) its complex structure (2) using words to refer to intangible things (3) using language to name, categorize, and describe things to ourselves when we think i.e. thinking and conceptualizing
Phonemes
smallest units of sound that are recognizable as speech rather than as random noise; building blocks of spoken language that differ in production
Phonological rules
indicate how phonemes can be combined to produce speech sounds; typically learned without instruction
Morphemes
combination of phonemes; smallest meaningful units of language
Morphological rules
indicate how morphemes can be combined to form words
Content morphemes
can stand alone as words; refer to things, places, and events
Function morphemes
can stand alone as words; serve grammatical functions like connecting sentences (“and”) or indicating time (“when”)
Syntactic rules
indicate how words can be combined to form phrases and sentences (must contain 1 or more nouns, 1 or more verbs)
3 characteristics of language development
(1) children learn language at a rapid rate (2) children make few errors (e.g. overregularizing) while learning to speak (3) children’s passive mastery of language (understanding) develops faster than their active mastery (speaking)
What can infants do at birth?
Distinguish among speech sounds (ONLY within first 6 months) but cannot produce them dependably
Babbling
combinations of vowels and consonants that sound like real syllables but are meaningless; a natural part of the language development process; signals a state of focused attention, ready to learn
Fast mapping
quick process whereby children map a word onto an underlying concept after only a single exposure
Telegraphic speech
At 18-24 months, children start forming 2-word sentences (noun + verb), devoid of function morphemes and consist mostly of content words, have meaning but are grammatically incomplete
How does language development typically unfold?
as a sequence of steps where a child achieves one milestone before moving to the next
Behaviorist explanation of language learning
we learn through operant conditioning (reinforcement by adults, shaping, extinction) and imitation; cannot account for many fundamental characteristics of language development (cross-cultural and distinguishing phonemes as infants)
Nativist explanation of language learning (Nativist theory)
language development is best explained as an innate, biological capacity; rapidly acquired through simple exposure to speech and the human brain is equipped with universal grammar (Chomsky); has more evidence than the behaviorist theory
Universal grammar (Chomsky)
collection of processes that facilitate language learning
Genetic dysphasia
syndrome characterized by inability to learn the grammatical structure of language despite having otherwise normal intelligence
Interactionist approach of language development
biological capacity/predisposition for language combines with environment experience/social interactions
Language centres of the brain
Broca’s area and Wernicke’s area, connected by a pathway called arcuate fasciculus
Aphasia
damage to Broca’s and Wernicke’s areas, difficulty in producing or comprehending language
