Reading Flashcards
What are the three processes involved in reading?
- orthography
- phonology
- semantics
types of research methods that can be used to study reading …
- lexical decision tasks (decide quickly is a string of letters forms a word)
- Naming task (pronounce aloud visually presented words as quickly as possible)
- Priming (influence the processing of a target by presenting a stimulus beforehand)
how to record attention processes in reading ..
by recording eye movements , it provides a detailed record of attention
what is the weak phonological model of reading?
phonological processing of visual words is relatively slow and inessential for word identification
what is the strong phonological model of reading?
some phonological coding occurs rapidly when a word is presented visually, this process is automatic
what did masked phonological priming find?
word processing was faster when preceded by phonologically identical non-words than by primes similar in orthography
e.g. faster processing of clip when the prime was klip and not pilp
neuropsychological evidence for reading
patient PS
understood meanings of words but could not process them
conclusion of phonological reading
the weak model, underestimates the importance of phonological processing… it causes rapid recognition and phonemic skills predict reading skills
however processing may occur after accessing word meaning
automatic processing theory of reading
word recognition is fairly automatic (rayner and sereno)
word superiority effect of reading
a letter string is presented very briefly followed by a pattern mask
they were asked to determine which of two letters was presented at a particular position
position is better determined when a word is presented
interactive activation model for word recognition
the stimulus is seen which activates the feature level, this goes on to the letter level allowing people to identify letters before sending this info to the word detectors to identify the full word
how orthographic neighbours effect word identification time
when a word is presented orthographic neighbours become activated, increasing the time necessary to correctly identify the target word
strengths and weaknesses of the interactive activation model
strengths - shows connectionist processing system can be applied to visual word recognition
weaknesses - ignores phonological processing and is only designed for four letter words
context effects on word recognition
- semantic priming effect
an expected target category had facilitatory effects on reading
what are the two approaches for reading aloud?
dual-route cascaded model
distributed connectionist approach
what is dual-route cascaded model?
processes involved in reading that is generally rule-based
- a weak phonological model
- individuals use both non-lexical and lexical routes but mainly lexical routes when reading aloud
what is the distributed connectionist approach?
various processes involved in reading are used flexibly
- all relevant knowledge is called to the fore, such as word sounds, spellings and meanings
What is the non-lexical (route 1) in the dual-route cascaded model?
converting spelling (graphemes) into sound (phonemes)
if this process doesn’t occur correctly it can result in surface dyslexia
what is surface dyslexia
causes problems reading irregular words
41% irregular word accuracy in patient KT.
mispronunciation was due to regularisation of words
what is the lexical and semantic route (route 2) used in dual-route cascaded model?
in the lexical route, familiar words are stored in an orthographic input lexicon , when the meaning is activated and sound pattern is generated in the phonological output lexicon
issues using this route results in phonological dyslexia
what is phonological dyslexia?
causes difficulties in reading unfamiliar and nonwords
what is route 3 in the dual-route cascaded model?
it is a lexicon only route
what is deep dyslexia?
issues reading unfamiliar words, inability to read nonwords and causes semantic reading errors
is seen in those with brain damage to language areas
neuroimaging evidence for the dual-route cascaded model
lexical route: left anterior occipital-temporal region
non-lexical route: left posterior occipital-temporal region
