The Simon task was employed to establish the nature of the representation of printed words with which the mental lexicon is accessed. In the first five experiments, the subjects were required to discriminate target letters in words or nonwords, presented vertically or horizontally. The targets were located in the left (upper) part or the right (lower) part of the letter string. The response keys were placed either horizontally or vertically. In Experiments 1, 3, and 5 the subjects were asked to make a lexical decision and to respond only to targets within words or nonwords. In Experiments 2 and 4 the discriminative response was emitted regardless of the lexical status of the letter string. In all experiments, a Simon effect was found that as congruent with the mode- horizontal or vertical- of stimulus presentation. In Experiments 6 and 7, the letters were all presented at fixation. The results showed the Simon effect in the horizontal dimension, as long as the subjects were given enough time to produce a visual image of the letter string. It was concluded that the canonical representation of the word is produced only when the mode of stimulus input does not itself yield a spatial representation. |
