Chapter 9: Language and Thought Flashcards
language
a set of symbols used to communicate
what are two components of language?
language production and language comprehension
language production
the structured and conventional expression of thought through words
speech
the expression of language through sounds
language comprehension
the process of understanding spoken, written, or signed language
what four areas is the study of speech divided?
phonology, semantics, syntax, and pragmatics
phonemes
the smallest unit of sounds in a language; an individual sound such as ba, da, ta; associate with PHONOLOGY
phonology
the study of how individual sounds or phonemes are used to produce language
morphemes
the smallest units of language that convey meaning; associate with SEMANTICS
semantics
the study of how meaning in language is constructed of individual words and sentences
lexical meaning
dictionary meaning of a word (can change over time); associate with SYNTAX
syntax
the system for using words (semantics) and word order (grammar) to convey meaning
pragmatics
the practical aspects of language usage, including speech pace, gesturing, and body language
non-verbal communication
body language; associate with PRAGMATICS
what are the two stages in the first 2-4 months of life?
prevocal learning (babies perceive and distinguish phonemes) and cooing (non-crying vocalization)
babbling (6 months)
meaningless production of sounds, allows baby to experiment with vocalizations
first words at spoken after about….
1 year - ability to comprehend is greater than ability to speak
telegraphic speech (2 years)
speech that consists of minimalistic sentences; grammatical morphemes are dropped (words not necessary for meaning of the spoken phrase)
pragmatics (3 years)
acquired practical info about language use
grammar (4 years)
automatically absorbed many of the rules of grammar
early capacity for language learning may signal presence of:
a language acquisition device in the brain
there is a debate between presence of a:
critical and sensitive period of language learning
critical period
a window of time in development during which certain influences are NECESSARY for appropriate formation of the brain
sensitive period
a point in development during which the brain is more SUSCEPTIBLE to influences
an interactive theory of language suggests that:
experience interacts with biological development to guide and enhance language learning
