The generation of regular and irregular inflected verb-forms has been taken as a crucial test between models of inflection in the mental lexicon, namely approaches which invoke different mechanisms for regular and irregular forms (rule-based procedures vs. recovery of whole forms stored in an associative network) and accounts which postulate a single procedure for all forms.

Abstract

The generation of regular and irregular inflected verb-forms has been taken as a crucial test between models of inflection in the mental lexicon, namely approaches which invoke different mechanisms for regular and irregular forms (rule-based procedures vs. recovery of whole forms stored in an associative network) and accounts which postulate a single procedure for all forms. An alternative hypothesis suggests that inflectional processes are explained by membership of words to clusters, for instance, Italian inflectional classes (conjugations). In a behavioural and a rapid event-related fMRI experiment, participants overtly generated the past participle of verbs from the three Italian conjugations. Results showed that the cognitive operations and the neural substrate underlying inflectional processes rely on specific properties of inflectional classes. Different patterns of cortical activations elicited by verbs from different conjugations were detected for the first time in the left middle frontal gyrus, left pre-supplementary motor area and left anterior cingulate cortex.
