Chapter 11: Language Flashcards
how many words are in the vocabulary of an average American adult?
42,000
how many messages can the average American adult produce?
an infinite number of messages
Psycholinguistics
the subfield of psychology concerned with how we learn, understand, and produce language
examples of other species communciating
- Ants communicate using the transfer of chemicals called pheromones
- Bees communicate information about their food source using a complicated waggle dance
- Male Campbell’s monkeys have their own proto-syntax (different sequences of sounds signal different information) with 3 basic sounds that they can combine to signal different inforamtion
can animals communicate complex information?
Animal communication tends to be highly limited
what’s the most fundamental difference between human and animal language
the presence or absence of grammar for combining words
Productivity/digital infinity
a feature of human language in which an effectivity infinite number of grammatical sentences are possible
Noam Chomsky on language’s uniqueness
language’s infinite expressive ability is what makes it so unique
Alex the Parrot
was trained to produce some remarkable linguistic behaviours, including describing abstract concepts. However, he was never able to generate a novel, multiword sentence using grammar
Washoe the chimp
was able to learn up to 350 signs and combine words to create new ones, but he never reached any true linguistic competency such that he could generate novel, multi-sign sentences
can animals produce true language?
Animals are unable to produce true language even with extensive training
Behaviourists like B.F. Skinner on language acquisition
propose that all language is learned through reinforcement and modelling
Noam Chomsky on language acquisition
there is an innate capacity to learn language that is present prior to any actual language experience
universal grammar
a theorized set of syntactic linguistic rules that are present across all natural human languages
what gene is thought to be involved in language?
FOXP2
why do researchers think FOXP2 is involved in language?
is involved in language because children who have mutations in this gene often suffer from developmental verbal dyspraxia
Developmental verbal dyspraxia
a disorder that affects the ability to pronounce syllables and words
FOXP2 knockout in female mice
they don’t generate high-frequency vocalizations in response to their pups
FOXP2 knockout in songbirds
affects their ability to learn and imitate their characteristic songs
Poverty of the stimulus
a proposed phenomenon that states that there is insufficient data for children to learn the rules of grammar based on experience alone
Pidgin
a quasi-language that does not contain full grammar, typically generated by adult immigrants to a location with a different language
Creole
a fully expressive novel language consisting of a combination of two pre-existing languages, typically created by the children of immigrants who are exposed to their parents’ language alongside that of their current resilience
what is a creole an example of
people acquiring grammar without sufficient stimuli
Deaf isolates
people who can’t hear but are not exposed to any real sign language
do deaf isolates communicatie?
They will develop their own sign language, demonstrating an innate capacity to learn a language
when does language learning begin?
before birth; Infants’ sucking responses in the womb demonstrate a preference for their mothers’ voices and their native language
language abilities 0-3 months
cooing
language abilities 4-8 months
babbling (consonant & vowel)
language abilities 1-2 years
two word phrases
language abilities 2-3 years
explosion of word knowledge; 2-3 word telegraphic speech
language abilities 8 months- 1 year
single words
language abilities 3-4 years
complex multiword speech
language development in different environments
The regularity of linguistic development persists even when there’s a high degree of linguistic difference in environments
Child-directed speech (CDS) or infant-directed speech (IDS)
speech that is tailored to a young infant or child
Motherese/ parentese
an infant-directed way of speaking that involves sing-song like speech cadences, exaggerated vowel pronunciations and repetition
do infants show a preference for types of speech?
they prefer IDS
head-turn task
a behavioural task used in infant language testing where babies are conditioned to turn their head when they hear a change in sound
Liu et al., 1993 motherese experiment
assessed the abilities of 6-12 month old babies to discriminate between different speech sounds using the head-turn task. Found that the language abilities of infants were positively correlated with their mother’s use of elongated and open vowel sounds, typical of motherese
are IDS & motherese necessary for language development?
no
phonemes
the smallest unit of speech that can change the meaning of the world
phonemes for apple
ah, p, l
morphemes
the smallest meaningful units of speech, which have to convey some meaning either on their own or in combination with other units of speech. This includes prefixes and suffixes
morphemes for apples
apple, s
Pollack & Pickett, 1964 context and speech experiment
They found that people could correctly identify the word less than half of the time, but when several words from before or after the target word were included, people were better at identifying the word. Demonstrates that context plays an important role in speech perception
phonemic restoration effect
a perceptual phenomenon in which sound that is missing or obscured is still perceived if it is highly predictable
who discovered the phonemic restoration effect?
Warren, 1970
what type of processing is phonemic restoration effect based on?
top-down
Warren, 1970 phonemic restoration effect experiment
played participants a recording with a phoneme covered with a cough. Found that most participants didn’t notice any sounds missing
McGurk effect
when we view the visual articulations of one phoneme while hearing the auditory signal consistent with another. Demonstrates that our brain uses additional info besides the speech stimulus to determine what phoneme is being said
main challenge to speech segmentation
The fact that we do not pause between words
Saffran et al., 1996 artificial language and preferences experiment
Found that babies showed a clear bias towards nonwords and that they encoded the frequency with which different sounds appear together, allowing them to identify words
lexical processing
determining the meaning of individual words
homophones
words that are pronounced identically but have different meanings
homographs
words that are spelt identically but have different meanings
why do we prefer commonly used words?
because they are processed quicker
context is important for
disambiguation
Lexical decision task (LDT)
a psychological task in which a participant makes a quick decision about whether a given string of letters is a legitimate word or not
Scarborough et al., 1977 commonly used words experiment
used the LDT and found that people were faster at recognizing strings as real words when those words were more common
Swinney, 1979 LDT and homophones experiment
Had participants perform a LDT while listening to one of the versions of the homophone and found that participants’ response times were faster in the LDT when related words were presented together.
are both meanings of the homophones activated?
both meanings are briefly activated despite the surrounding context favouring one meaning
parsing
breaking up languaging into its constituent parts
garden-path sentence
a sentence that tends to induce the wrong parsing
clause
a group of words that express a full idea of someone or something
subject
someone or something
predicate
the verb
syntax-first approach
a theory of language parsing that holds that the parsing of a sentence is first derived based on principles of grammar alone without regard to the meaning of the words, except to determine which grammatical category they belong to
late closure
a tendency when parsing to attach incoming words to the current phrase
Trueswell et al.,1994 eye tracking and prosody experiment
presented participants with sentences that contained parsing ambiguity and tracked their eye movements to see whether they had to go back and reanalyze each sentence. Found that the meaning of words affected parsing.
Tanenhaus et al., 1995 visual input and parsing expeirment
presented participants with sentences that contained parsing ambiguities, and tracked their eye movement while also showing them visual stimuli. Found that the visual information affected parsing behaviour.
prosody
the patterns of stress and intonation (pitch) of the speaker, which can convey critical information
punctuation and prosody
Punctuation can be seen as a limited version of prosody
discourse processing
The ability to understand language that is at least several sentences long
anaphoric inference
an inference that connects a reference to an object or a person in one sentence to an object or person in a different sentence
causal inference
an inference about the causal relationship between information in one sentence regarding information in another sentence
backward inference
a kind of inference in discourse processing in which previous information is needed in order to process current information
elaborative experiment
a kind of inference in discourse processing in which the inferred information is not necessary in order to properly understand the text
when are participants more likely to report information as novel?
if it was consistent with their expectations
when do people engage in inferential reasoning?
at the single-word level as they are reading
instrumental inference
a form of elaborative inference in discourse processing in which the tool or instrument that is typically used to perform the task is inferred from the task
who discovered instrumental inferences
Singer, 1979
when do people engage in online elaborative inferences?
if they have enough context
example of the importance of context in inferences
participants understood a text much better when they were told it was about doing laundry because it allowed them to relate the text to their prior experiences
Neurolinguistics
a branch of linguistics concerned with the relationship between linguistic behaviour and the structures of the brain
Wernicke’s area
- critical for language comprehension
- Located in the temporal lobe
- The first region of the cortex to receive auditory information after the thalamus
