PSY2002 W1 Language I - Core Reading Flashcards
An introduction to computational models of speech production
What stages does speech productino involve
Semantic, syntactic, morphological adn phonological
What is a Discrete Models?
Are modules that have seperate parts that do not interact.
What is a Interactive Model?
It is a flexible interactive model, where sections/parts interact with one an other.
Similarities between speaking and writing
Start with planning which then follows by language production. Children usually learn to writer after they have developed spoken-language skills.
Differences between speaing and writing
Written languge: longer/complex construction, laregr vocab, permanent adn have direct access to production.
Speech: time-bound, less planning, direct verbal/non-verbal feedback.
What could be behind the fact that during speech comprehension adn production the same brain areas are activated?
could be due to the same processes are occurring or different processes occur within the same brain area.
What is more cogntiively demanding
Speech prodcution (greater impairment in attentin task) over speech comprehension.
Syntactic priming
tendency for speaker’s utterances to have the same syntactic structure as those they have heard shortly beforehand.
Preformulating
production by speakers of phrases used frequently before it reduce the demands of speech production.
Underspecification
strategy used to reduce processing cost in speech production by using simplified expressions.
Stages in speech production
Semantic, Syntactic, morphological and Phonological level
Word exchange errors
involve word belonging to the same syntactic/grammatical category, errors occur during grammatical encoding.
Sound- exchange errors
involve nearby elements within a phrase, during phonological encoding.
Factors influencing advance planning
slower speakers plan more, more planning before speaker produced simple rather than complex, more planning under low cognitive load.
Flexibility- speach planning - Ferreira and Swets, 2002
No time pressure speakers planned their response, time pressure speakers engaged in limited planning and did additional planning during the speaking.
Spoonerism
speech error in which the initial letter or letters of two words are switched to form two different words.
Freudian
speech error that reveals speakers sexual desires
Semantic substitution errors
occur when the correct word is replaced by one of similar meaning
Morpheme-exchange errors
involve inflectino or suffixes being attached to wrong word
Two factors causing speech errors
Planning processes relating to the targets of articulation.
Articulatory processes specifying the motor movement required to execute this plan.
Perceptual Loop theory (Levelt 1983)
explains error detection by monitoring their utterance. Inner speech (typically occur faster) and over speech ( speaker make use of auditory feedback, the comprehension system detects own speech errors
==> viewed as incorrect
Conflict-based Monitoring theory Nozari 2011
Conflict based account predicts speaker ability to detect their speech errors depends on the quality of their speech production system.
Spreading activatino theory - Delll 1986
Activation of a node (corresponding to a word/concept) in the brain causes some activation to spread to several related nodes or words.
Based on speech errors.
Processes can occur in parallel (at same time) at different levels. Processing is interactive, can be cascade processing.
Mixed-error effect
A form of speech error in which the incorrect word spoken is related to the correct one in terms of both meaning and sound.
