Lexical Representations of Written Nouns and Verbs in Italian

This study investigates the differences in the input representations of verbs and nouns in the Italian mental lexicon. One visual lexical decision experiment in which the stem homograph effect (Laudanna, Badecker, and Caramazza, 1989) was evaluated on noun and verb targets is reported. Strong inhibitory effects on verb targets preceded by stem homographs relative to nonhomographic word pairs were found. The effects on verb targets were also much more reliable than the effects on noun targets. The pattern of results provides support for the hypothesis that noun and verbs are differently represented in the orthographic input lexicon.

Representation of grammatical properties of Italian verbs in the mental lexicon

The present study focuses on the representation of verbs in the Italian mental lexicon and investigates some grammatical properties: inflectional class, mood, tense, and person. Two experiments based on free recall of single inflected forms are reported. The patterns of recall and error are taken as evidence for the grammatical and morphological information exploited in the access to the verb forms. The pattern of results provides support for the hypothesis that in the mental lexicon the information about conjugation and mood is an organizational criterion for the representation of verbal forms. An interaction between mood and conjugation, likely to arise from the difference in productivity between conjugations, is also observed.
