Agreement in the oral Italian of Swedish university students : The acquisition of number and gender from a functionalist perspective

This study investigates the acquisition of grammatical gender and number agreement in Italian as a second language (L2). The theoretical framework is based on a functional approach that stresses the importance of form function mappings, cues, frequency effects and the statistical properties of the language input. The Competition Model is of particular importance and the Italian oral corpus LIP is used to make calculations that measure the validity, availability and reliability of the Italian noun endings. The data consists of 71 transcribed teacher-student dialogues with Swedish learners of Italian at Stockholm University. The results show that learners have problems with feminine gender in the plural and with ambiguous noun endings, i.e. cases where one form is connected to more than one function. These findings can be explained by cue competition and frequency effects and to some extent by a markedness effect. A second study with time (longitudinal development) and reliability of the noun endings (high or low) as independent variables and degree of accuracy as dependent variable showed a positive increase in accuracy rates over time, both for low and high reliability noun endings. There was also a significant interaction effect between the two independent variables according to which cases of agreement with low validity noun endings showed a higher increase in accuracy rates than high validity noun endings. This could be explained by the power law of practice, i.e. cases of agreement with high reliability noun endings soon reach a very high level of accuracy from which it is difficult to make further progress
