  • Writing systems
  • How do we read
  – mapping orthography to phonology and 
  semantics
  • Classic experimental findings
  • Learning read
  
  Models of Reading
  • What are the mental processes involved in 
  reading?
  • How can we explain effects of 
  – frequency
  – regularity/neighborhood
  – lexical influences (e.g., priming)
  • What does reading tell us about how the 
  mind works
  – modularity, local vs. distributed information
  
  Why have a model?
  • A coherent implementation of a theory
  • Explains existing data
  • Makes predictions for future research
  – helps reject/modify a theory 
  • Can be implemented as a computer 
  simulation
  – but some are not, just a model on paper
  
  Morten’s Logogen Model
  • Logogen: another word 
  for ‘lexical entry’
  • Each logogen has visual, 
  acoustic and semantic 
  features associated with it.
  – it becomes active when 
  enough of these features 
  activates it
  – logogens compete for 
  activation
