Context |
Normal subjects are faster at recognizing that a string of letters corresponds to a legitimate word of the language when the string corresponds to a frequently occurring word (e.g., house) than when a less frequent sequence (e.g., enzyme) is presented (Gordon, 1983; Howes & Solomon, 1951; Morton, 1969). This finding, usually referred to as a FREQUENCY EFFECT, holds true with both orthographic representations in reading and phonological representations in auditory recognition. These observations have been taken as evidence that the frequency of occurrence of an item in the language is reflected in the ease and speed with which lexical representations are activated.
