PSY2002 SEMESTER 1 - WEEK 1 Flashcards
define model
simplified/idealised representation of thing
explain difference between statistical and theoretical cognition model
statistical does math relationship between variables held under specific assumptions
theoretical cognition describes relationship between different mental processes that makes assumptions about nature of these processes
give example for a computational model
implemented as functioning computational models
eg; neural network with node representing group of neuron
name 2 strategies to reduce processing demands while planning what next to then say
preformulation, underspecification
define preformulation
producing phrases used before
define underspecification
using simplified expressions in which full meaning is not explicit
what are hesistations for and why can we use them to test speechs production
how long it takes to initiate word (find and plan relevant syntax)
explain tip of tongue state
unable to retrieve necessary word, due to planned sentence and structure, with syntax in place but specific levels of processing is required to produce speech
name 3 levels of tip-of-tonge state
semantic processing
syntactic and morphemic processing
articulation (form processing)
speech error tend to occur within specific process
when do speech errors tend to occur
within following processes, rather than crossing boundaries between them:
1. semantic processing
2. syntactic and morphemic processing
3. articulation (form processing)
name errors at semantic processing level
semantic blend error at conceptual level eg; spork
or semantic substitution- correct word replaced by word of similar meaning eg, bat/raquet
name errors in syntactic and morphemic processing
syntactic and morphemic exchange errors at formulation level eg; slicly thinned
inflection/suffix remains in place but attached to wrong words eg; already suitcased 2 packs (already packed 2 suitcases)
name errors in articulation processing levels
word and phoneme exchange eg; forks of a prong
what is Fromkin 1971 model of utterance generation (5 stages)
serial processing (discrete)= each stage must be completed before next can begin
1. meaning generated (eg; prongs of fork)
2. syntactic structure generated and associated with semantic features (work out layout)
3. position of intonations placed (first article ‘prong’, second ‘fork’)
4. lexicon look up find word, generate phonological segment (finds words prongs and fork)
5. morphophonemic constraints added, phonemes selected for utterance (the, of, a)
give an overview of Dells Spreading Activation Theory (computational)
spreading activation results in activation of related items at all level of processing at same time, cascaded interactive model, semantic and phonemic info processed simultaneously, processes at one level can influence processes at other level
name 4 levels of speech production
- semantic level
- syntactic level
- morphological level
- phonological level
what is the semantic level of speech production
meaning of what is to be said - planning level
