The availability of context was varied in a letter-deletion manipulation in subjects’ reading of a brief passage. The task of supplying missing letters in words presented in the absence of context was more difficult than supplying missing letters for words in context, as determined by study time and number of correct responses. Levels of recall in the noncontext condition, however, were significantly lower than in the context condition, suggesting that the task of supplying missing letters for words in passages requires processing beyond individual lexical items. It seems that the processing required for such tasks is similar to that required by readers when they encounter unfamiliar vocabulary.
