This study examines two views of lexical storage and word production, a derivational hypothesis and an independent unit hypothesis. Reaction times and errors were related to derivational complexity. A model of lexical retrieval process incorporating derivational processes is proposed. (Author/SW)

Describes three experiments conducted to examine the superior retention of related word pairs when the second word in the pair required active construction by the subject. The results confirm the importance of subjects' checking solution adequacy and of associative relationships in recall. (PMJ)

Predictions were derived from the assumption that the vocabulary store underlying the auditory analysis of verbal stimuli is organized as an acoustic space rather than as a lexicon (tree) or collection. The relationship between frequency of occurrence in the language and frequency of occurrence as an error is low. (Author/SW)

In six experiments subjects saw and pronounced, either aloud or silently, seven-item lists made from vocabularies of phonologically identical items. These materials were used to test the predictions of a precategorical and a postcategorical hypotheses for the modality effect in immediate memory. (Author/SW)
