- TB6 D&L Lecture 1; Word Meanings and ambiguity
- How we understand words with more than one meaning
- What we already know
- Gating; context influences recognition point
- Cross-modal priming; numerous meanings are briefly activated
- Terminology of ambiguity
- Homophone
- Homograph
- Homonym
- Polysemous (senses)
- Heterographic homophone/ homograph
- Meaning frequency?
- Balanced; meanings = common
- Unbalanced; meanings X= common
- Context and unbalanced homonyms
- Dom/sub meanings; context strongly constrains meaning
- Selectivity in terms of context dominance
- Multiple access; SUB-ORDINATE constraining context
- Selective priming; DOMINANT constraining context
- Evidence AGAINST a strong modular account (both models are relevent)

- Selective priming; DOMINANT constraining context
- Evidence AGAINST a strong modular account (both models are relevent)
- What we already know
- Models of the influence of sentence context on meaning selection
- Multiple Access Model
- Swinney (1979)
- Upon ambiguity, ALL MEANINGS are accessed in a context-independent way
- Only the contextually appropriate meaning selected
- Context-guided single-reading lexical access model
- Schvanevelt (1976)
- Conext used to RESTRICT ACCESS to only the appropriate meaning
- Inappropriate meanings are NEVER accessed
- Multiple Access Model
- Evidence to support the different models
- Rodd et al; (2002) Lexical decision task
- Word recognition FASTER for words with fewer meanings and many senses
- Word recognition is NOT independent of meaning
- Word recognition FASTER for words with fewer meanings and many senses
- Online tasks
- Cross-modal priming
- Biasing contexts
- Swinney (1979); activation of meanings of ambiguous words (lexical decision task)
- Early v.s late effects of context
- Context has no effect on both early access OR later presentation
- Boh meanings are still primed; MULTIPLE ACCESS
- Context has no effect on both early access OR later presentation
- Early v.s late effects of context
- Swinney (1979); activation of meanings of ambiguous words (lexical decision task)
- Measure meaning activation
- Biasing contexts
- Cross-modal priming
- Meta-analyses
- Lucas (1999); sentential context effects
- Semantic ambiguity tasks in patients in PVS
- Rodd et al; (2002) Lexical decision task
- How we understand words with more than one meaning
