Common and Differential Factors in Reading Vocabulary and Hearing Vocabulary

Numerous studies have shown that recognition of word meaning is closely related to reading ability. All of these studies, however, measured reading vocabulary only. This research attempts to determine how recognition of read and heard words compares, and how the two types of vocabulary are related to reading ability. Since material is held constant, but the mode of presentation is varied, this approach should make possible the study of certain common and specific elements in the abilities to recognize words read and heard, and to determine the manner in which this relationship is affected by reading ability
