Chapter 11: Language Flashcards
Language
a system of communication using sounds or symbols that enable us to express our feelings, thoughts, ideas, and experiences
Unique property of human language that makes it exclusive
creativity to create new and unique sentences due to its hierarchical and rule-based nature, unlike animals
Hierarchical nature of language
it consists of a series of small components that can be combined to form larger units
Basic components of language
phonemes, morphemes, prosody
Phonemes
smallest possible sound component
Morphemes
smallest possible meaningful component
Prosody
the pattern of intonation and rhythm in spoken language
Rule-based nature of language
components are arranged in certain ways and follow syntactic rules (grammatical and phonological)
Psycholinguistics
field concerned with the psychological study of how humans acquire and process language
4 major concerns of psycholinguistics
comprehension, representation in the mind, speech production, acquisition
Why are birds and chimpanzees considered to have no language?
chimpanzees can memorize a few hundred symbols but cannot perform syntax; birds vocalize more than humans but meaning is limited to specific calls
Lexicon
all of the words we know; “mental dictionary”
Semantics
the meaning of language
Lexical semantics
the meaning of words
Word frequency
the frequency with which a word appears in a language
Word frequency effect
we respond more rapidly to high-frequency words like home than low-frequency words like hike; our past experience with words influences our ability to access their meaning
Lexical decision task
decide as quickly as possible whether a string of words are words or nonwords
Speech segmentation
perception of individual words even though there are often no pauses between them
4 factors affecting our ability to hear and understand spoken words
(1) how frequently we have encountered a word, (2) the context in which words appear, (3) our knowledge of statistical regularities of language, (4) our knowledge of word meanings
Lexical ambiguity
words often have more than one meaning
Hypoglossal nerve
controls the tongue and exits the skull through the hypoglossal canal, which is the same size for pre-linguistic and modern humans
What is the earliest evidence of symbolic language?
ochre plaque made in South Africa ~75000 years ago; also earliest evidence of trade and flint mining
Tattersall’s theory on how humans acquired symbolic representation
acquired suddenly as a byproduct of another process or epiphenomenon (e.g. fine motor control, musical ability) rather than through incremental development
Support for musilanguage hypothesis
(1) syntax of music is simpler/it has less rules, (2) modern language itself is musical, has prosody and rhythm, (3) newborn infants respond to baby talk or prosody before syntax, prefer rhythm and tone of mother’s language
Gesture communication (McNeil)
suggests gesture is more primary than speaking as restricting hand movements reduced fluency of speech (more pauses)
Origin of language vs music
capacity for music predates language in historical/phylogenetic terms and developmental/ontogenetic terms; language began to be used 40-80k years ago but early evolution is still unknown
Left vs right hemisphere functions in language
left is involved with labels, abstraction, categories while right is involved with ambiguity, context, metaphor, humor; left talks over the meaning known by the right
Lexical priming
seeing a word makes it easier to respond to another word with a similar meaning that is presented after
Tanenhaus et al. findings on lexical priming
people briefly access all meanings of ambiguous words before context clarifies meaning; priming is suppressed after 200 ms delay
Meaning dominance
relative frequency of the meanings of ambiguous words
