Intro to comprehension Flashcards
(20 cards)
What are the building blocks of language for comprehension
speech
form
semantics
morphology
syntax
ambiguity in the speech stream
impossible to know where one word ends and another one starts
ambiguity at the world evel
word that sound the same but have different meanings
ambiguity at the phoneme level
WORDS THAT CHANGE THE WAY THEY SOUND DEPENDING ON THEIR ENVIRONMENT
what are word boundaries
impossible to know ehre one word ends and another one starts
two words that run/connect with each other - causes an issue with word boundaries
what a homonyms
words that sound the same and spelt the same
what are homophomes
words that sound the same
what are homographs
words that are spelt the same
how are we able to distinguish between sounds
voice onset time
define voice onset time
the point at which vocal chord vibrations stars relative to the release of a closure.
What problem can regional accens create
invariance problem
define the invariance problem
the inability to define the acoustic properties that facilitare categorisation of phonmes.
categorical perception
we can use voice onset time to help distinguish phonemes
top down processing
activaiton of exsisting lexical representations may help us understand words, dialects, foreign accents and manage incomplete bottom-up information
phoneme restoration effect
uses mental lexicon to fill in missing phonemes
lexical access will be faster for what words?
words that are short and frequent compared to words that are long and infrequent
lexical access will be slower for words
with lots of neigbours commpared to words with fewer neighbours
what is the lexical decision task
ps press one key for wrod and another key for non word
reaction times are measured as the time between stimulus presentation and button press
slow reaction times are found for words with lots of neigbours compared to words with few neighbours.
the system accesses lexical items based on
acoustic input
top down processing
lexical characteristics
activation of related items
context
name models of speech comprehension
the cohort model
the trace model.
