L2 Spanish verb morphological development as explained by phonological neighborhood density Speaker: Eva Rodriguez Gonzalez, University of New Mexico
Authors: Eva Rodríguez González
Research into lexical processes shows that phonological similarity (neighborhood density) affects processing and retrieval (Luce & Pisoni, 1998): in English words with dense neighborhoods are responded to more slowly and less accurately than words with sparse neighborhoods (Frauenfelder et al., 1993; Luce & Pisoni, 1998). Contrary to the competitive effect found in English, neighborhood density appears to have a facilitative effect on word perception and production in L1 Spanish (Vitevitch & Rodríguez, 2005). The question that arises, then, is whether learners will transfer their mechanisms of lexical processing and retrieval from their L1 (English) to their L2 (Spanish). The present study examined neighborhood density effects across L2 Spanish verbs (40 bisyllabic Spanish Preterite inflected forms). Neighborhood density was calculated via L2 subjective ratings and B-Pal phonological neighborhood counts (David & Perea, 2005). Controlling word length and manipulating frequency of occurrence, neighborhood density and verb type, a visual lexical decision task was given to 60 beginning, intermediate and advanced university-level learners of Spanish. Significant word frequency and neighborhood density effects related to speed and accuracy of responses were found. Results for beginning and intermediate learners were similar to what has been observed in English: high frequency words and words in sparse neighborhoods were perceived and produced more quickly and more accurately than low frequency words and words in dense neighborhoods. For the advanced learners, however, high frequency words and words in dense neighborhoods were perceived and produced more quickly and more accurately than low frequency words and words in sparse neighborhoods. The results indicate that there is a direct relationship between word frequency, neighborhood density and L2 lexical development in verbal paradigms. Differences of processing effects are characterized in terms of L1 transfer and show how transfer and morphological complexity interact in the data.
