Sentance Perception Definition
How is meaning understood from spoken/read words?
Sentence Production Definition
How are spoken / read words chosen to convey meanings?
Modular vs Interactive Models
Individual stages are isolated or linked
Holistic vs Incremental Production Models
Pre-planned as a whole or one at a time
Serial vs Parallel production models
Serial = Each stage has to be completed before the next stage occurs - independent of each other
Parallel = Stages aren’t independant of each other
Examples of Serial Errors
Phoneme Exchange Errors = Two phonemes in the same position
Word Exchange Errors = Two words of the same class
Morpheme Errors = Two morphemes are accessed simultaneously
Examples of Parallel Errors
Mixed Errors = Semantic and Phonological co-activation
Anticipation Errors = A unit occurs in the right place and earlier in the utterance
Define Lexical Route Model in Spelling
Accessing detailed information about the word and used for spelling familiar words
Define Non-Lexical Route within Spelling
Conversion of sounds into letters , often when unfamiliar words are used
2 Types of Dysgraphia that are evidence of non-lexical model and Lexical Model in spelling
Phonological Dysgraphia = Difficulties using word sounds in spelling , difficulty spelling unfamiliar words (Non-Lexical)
Surface Dysgraphia = Pronounce misspellings that sound like regular words , difficulty spelling non regular words (Lexical)
3 Key processes in writing
1- Planning process
2- Sentence - generation Process
3- Revision Process
