Psycholinguistics How to Prepare for Exam 2 Performance/Morphology o Models o Dual route of naming -People can pronounce nonsense and unfamiliar words (sublexical route). -People can pronounce words that are spelled idiosyncratically (lexical route). -visual symbol (letter) to concept (lexicon) o Cohort Model -auditory word recognition -recognition point; strong emphasis on word onsets - 3 Stages: Access: Activate a set of possible candidates (prelexical) Access: Narrow the search to one candidate (prelexical) Integration: (Integrate single candidate into semantic and syntactic context. Postlexical) o Serial Bin search -Access of the lexicon is considered independent of other systems involved in processing language -A representation of the perceived stimulus is constructed -The representation is compared with representations in access files: 1. Orthographic 2. Phonological 3. Syntactic/semantic (for language production) -Access files are organized in a series of bins (first syllable or letters) -Position within the bins is organized by lexical frequency -Access files have “pointers” to meaning information in semantic memory HOW WORDS ARE ACCESSED? -Each bin is built around a root. The root gives the listener access to the polymorphemic word e.g. dog, dogs, dogpile, dog-tired -Within the bins, words are organized according to surface frequency -Morphological decomposition – affix stripping Support: -Words with more frequent roots are access faster than words with less frequent roots -Words with pseudo-affixes (sister) are more difficult to process than equally long and frequent words with real affixes (editor). o Types of priming o Semantic -Reaction time to a word (doctor) is faster if it is preceded by a semantically related word (nurse). This is called facilitation. On the other hand a semantically unrelated word (table) inhibits identification of the target. -The effect is very strong and very reliable. o Form (Orthographic) -Orthographically related forms, i.e. grate/ grade. Such primes have an inhibitory effect. o On-line/off-line -as processing actually occurs. No problem solving, no strategic planning involved. On-line processing is automatic, unconscious, fast, parallel, not susceptible to dual-task interference (interference from other tasks). (?) (ask about off line in class): Most of the information on the exam will come from the slideshows -- Wrap-up 1 and 2 (which focuses primarily on the Marslen-Wilson et. al. article). Libben and Taft will not figure in any prominent way in the exam, but familiarize yourself with their conclusions. From Marslen-Wilson et. al., you should know/understand • the features, o semantic transparency/opacity- synchronically compositional; derived from the meaning of the stem [+sem] happiness/happy [-sem] department/depart
