Three experiments are described which support the hypothesis that in a lexical decision task, prefixed works are analyzed into their constituent morphemes before lexical access occurs. Results compare classification times of nonwords that are and are not stems, of free and bound morphemes, and of stems and control items. (CHK)

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)
