Three lexical decision experiments tested the claim that lexical access is based on a word's basic orthographic syllabic structure (BOSS). No evidence was found that BOSS is a word's unique lexical access entry, and one experiment suggested that morphemic units are more likely to be access codes than purely orthographic units. (MSE)

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)

The relationship between the effects of morphological complexity and associative production frequency was investigated in two experiments on sentence verification. The purpose of the study was to investigate how morphologically derived words are represented in memory. (Author/RM)
