ABSTRACT

However, it is not only semantic impairments that can affect performance on wordpicture matching-breakdown in processing at any point from early auditory processing of the word or visual perception of the pictures can also affect accuracy. Hence, subject performance on a word-picture matching task might be affected by psycholinguistic variables that affect any of these levels of processing including imageability, word length, word frequency, and the relationship of the semantic distractors to the target word (Bishop & Byng, 1984; Schuell, Jenkins, & Landis, 1961). Each of these variables will be

discussed in relation to previously reported effects on comprehension for both normal and aphasic participant performance.
