For a performance-oriented notion of regularity in inflection: the case of Modern Greek conjugation

Paradigm-based approaches to word processing/learning assume that word forms are not acquired in isolation, but through associative relations linking members of the same word family (e.g. a paradigm, or a set of forms ?lling the same paradigm cell). Principles of correlative learning offer a set of equations that are key to modelling this complex dynamic at a considerable level of detail. We use these equations to simulate acquisition of Modern Greek conjugation,and we compare the results with evidence from German and Italian. Simulations show that different Greek verb classes are processed and acquired differentially, as a function of their degrees of formal transparency and predictability. We relate these results to psycholinguistic evidence of Modern Greek word processing, and interpret our ?ndings as supporting a view of the mental lexicon as an emergent integrative system.Secondo l\u27approccio paradigmatico allo studio dell\u27elaborazione e dell\u27apprendimento lessicali, le parole di una lingua non sono acquisite in isolamento, ma attraverso legami associativi tra membri della stessa famiglia morfologica, la cui dinamica ? modellata dalle equazioni dell\u27apprendimento correlativo. Il presente contributo offre una serie di esperimenti nei quali l\u27apprendimento del sistema verbale del greco moderno ? simulato come un processo di auto-organizzazione dinamica di parole memorizzate in modo concorrente. I risultati mostrano chiari effetti di interazione dinamica tra trasparenza e regolarit? morfologica nell\u27acquisizione di classi di forme del verbo greco
