Electronic resources for psycholinguistic research

What follows is a selective, annotated list of links that I have found useful enough to actually use:

• MCWord: An Orthographic Wordform Databasae
  (This tool, available from Jeff Binder's Language Imaging Laboratory and compiled by David Medler, is very useful for calculating orthographic neighborhood frequencies and generating lists of nonwords.)
  
• English Lexicon Project
  (David Balota's English Lexicon Project is a tremendous resource for data on both statistical characteristics of over 40,000 words and behavioral perforance using them in a lexical decision task.)
  
• Speech & Hearing Lab Neighborhood Database
  (Another useful site from WashU, this one provides neighborhood characteristics for words and familiarity ratings based on David Pisoni's Hoosier Mental Lexicon.)
  
• IPhOD: Irvine Phonotactic Online Dictionary
  (An good site for obtaining information on words such as phonological neighborhood densitites, number of phonemes, and number of syllables. It is freely downloadable or can be searched over the web.)
  
• WordNet
  (This well known and highly regarded resource is all about word meanings. The whole database is freely downloadable for fast searching.)
  
• Phonotactic Probability Calculator
  (If you can get Klattese translations of words for input, this is a useful tool for calculating phonotactic probability.)
  
• MRC Psycholinguistic Database
  (An electronic compilation of several databases, I have used it for obtaining familiarity and imageability ratings for words.)
  
• WebCelex
  (A very useful resource for obtaining lexical information such as word frequencies and phonological neighborhood densities.)
  
• USENET Orthographic Frequencies
  (This is the newest and most comprehensive corpus I am aware of for obtaining orthographic word frequency measures.)
