TB7 D&L Lecture 1; Key concepts
- Grapheme-phoneme conversion
  - The spelling-sound mapping rules of a language
    - Not just simple one-to-one mappings!
    - Different languages use different systems
      - Alphabetic (symbols code for sounds)
        VARY on orthography, from shallow (simple GPC) to deep (not clear and irregular/ inconsistent GPC)
      - Syllabic (symbols code for sounds at the syllable level)
      - Logographic (symbols code for MEANING)
  - Affected by;
    - Regularity
      - The degree to which the particular graphemes correspond to particular phonemes
    - Consistency
      - Is a particular spelling typically pronounced in the same way?
    - Any model of reading needs to account for such high rates of irregularity and inconsistency
- Phonemes and graphemes
  - Phoneme; the smallest unit of SOUND that can alter the meaning of a word
  - Grapheme; The basic unit of WRITTEN language. A letter/combo that corresponds to a phoneme
- Methodology for measuring word recognition
  - Lexical decision tasks
    - Reaction time
  - Semantic judgement tasks
    - E.g "is this a living thing?"
  - Eye tracking
    - Provides info on reading speed (decoding) and compre-hension monitering
  - Fluency/ efficiency of reading
    - Whole sentences/ paras
    - Single non/ words
- Ambiguity
  - Heteronym
    - Meaning + pronoun-ciation are DIFFERENT
    - SAME spelling
