Logical Instruments: Regular Expressions, AI and thinking about thinking

Perception of letters, words, and nonwords.

Letter vs. word and word vs. nonword identification were compared, with redundancy adequately controlled. The processing time of the test st imulus was varied to provide a number of levels of correct performance. The first experiment showed that letters were recognized better when presented alone than when embedded in words. In the second experiment, the identification of letters in words did n...
