• Resumen

  • This study examines the response patterns of 288 Spanish-English dual language learners on a standardized test of receptive Spanish vocabulary. Investigators analyzed responses to 54 items on the Test de Vocabulario en Imagenes (TVIP) [Dunn, L. M., D. E. Lugo, E. R. Padilla, and L. M. Dunn. 1986. Test de Vocabulario en Imganes Peaboy: Adaptacion Hispanoamericana. Circle Pines, MN: AGS] focusing on differential accuracy on items influenced by (a) cross-linguistic overlap, (b) context (home/school), and (c) word frequency in Spanish. The response patterns showed cross-linguistic overlap in phonology was a significant predictor of accuracy at the item level. After accounting for item number (expected difficulty level), context of exposure was a significant predictor of the likelihood of obtaining a correct response. Spanish word frequency was not a significant predictor of accuracy. The current findings substantiate the influence of cross-linguistic overlap in phonology and context on Spanish vocabulary recognition by Spanish-English speaking children. Children were more likely to obtain correct responses on lexical items that were associated with the home context. Researchers and practitioners should consider phonological cross-linguistic overlap in addition to context of word exposure and word frequency when designing and utilizing vocabulary assessments for children from linguistic minority backgrounds.
