comprehension
understanding what other say (or sign or write)
production
speaking (or writing or signing) to others
generativity
the capacity for language to generate an infinite number of sentences and express an infinite number of ideas
phonemes
the elementary units of sound used in a language
phonological development
the acquisition of knowledge about the sound system of a language
morphemes
the smallest units of meaning in a language
semantic development
learning the system for expressing meaning in a language, including word meaning
syntax
rules specifying how different kinds of words can be combined in a way that makes grammatical sense
syntactical development
learning about syntax
what is language?
structured, rule-based system of communication using symbols to communicate meaning
4 characteristics of language
symbolic, represents specific meanings, generative, structure/ rule-based
colourless green ideas sleep furiously
sentence from Noam Chomsky that follows the rules of language but doesn’t have a clear meaning
receptive vocabulary
comprehension: what words you’d understand if you encountered them (requires meaning, context, and intent). Develops earlier
productive vocabulary
production: what words you can spontaneously use yourself (requires recalling, forming and articulating)
predator-specific alarm calls in monkeys
come with strategies to behave differently depending on the call. Sophisticated communication, but not generative: can’t create new sentences or ideas. Therefore not language
Noam Chomsky Universal Grammar
set of highly abstract, unconscious rules that are common to all human languages
what do you need for language learning?
a human brain, rich environmental input, well-timed exposure
why is a human brain needed for language learning?
language is species-specific and species-universal, meaning only humans will acquire it and all humans will acquire it with typical development
Kanzi the bonobo
learned over 300 lexigrams and could combine them. Could follow verbal instructions but likely didn’t understand syntax
other examples of non-primate response to spoken language
Rico the dog retrieving toys by name (comprehension) and Alex the parrot speaking (associative and learned)
infant-directed speech
distinctive mode of speech that adults adopt when talking to babies and very young children. Preferred by infants and used by virtually all cultures
features of infant-directed speech
Warm, positive. Higher pitch, slower enunciation with swooping. Exaggerated facial expressions
benefits of infant directed speech
draws their attention, contrasts phonemes, improves word recognition
what is well-timed exposure for language learning
time during which language learning happens rapidly and effortlessly, an experience-expectant process (birth - middle childhood)
