PSYC 4000 Chapter Notes - Chapter 4: Prosopagnosia, Birdwatching, Bigram
Document Summary
2. the feature net and well-formedness: add bigram detectors (detectors of letter pairs) to make sense of words, unused combinations have really high activation levels, frequently used combinations in no-words create familiarity in just combinations. 3. recovery from confusion: when only seeing the bottom part of the o in corn look at other letters on either side for context, confusion overcame, confusion is usually overcome automatically. 4. recognition errors: corn is more well primed than cqrn so if the string to recognize, if string is meant to be cqrn then it will most likely be misremembered. Accuracy: inverse relationship, one is always sacrificed for the other, descendants of the feature net. 1. the mcclellan and rumelhart model: includes excitatory connections that allow the detectors to activate their neighbors, inhibitory connectors stop neighbors from firing, there is two way communication between the systems, words can activate letters or vice versa.
