Document Summary
Word recognition: in many studies participants have been shown stimuli for a brief duration (20-30ms). The first exposure primes the participant for the second exposure; more specifically, this is a case of repetition priming. Detectors likely involve complex assemblies of neural tissues (function in the way that"s biologically sensible): some detectors require a strong input to make them fire, while others will fire even with a weak input. This difference is created in part by how activated each detector is to begin with. As a result, the word will be more easily recognizable the second time around. The feature net and well-formedness: if none of the letter sequences create a word, the word detectors will play no role in the recognition of the strings. Page 88-104: adding another level to the net accommodation detectors for letter combinations, bigram detectors: detectors of letter pairs.
