Non-word repetition in Spanish-speaking children with Specific Language Impairment (SLI)

A number of previous studies have revealed that children with Specific Language Impairment have limitations in Phonological Working Memory as revealed by a task that requires them to repeat non-words of increasing syllable length. However, most published studies have used non-words that are phonotactically English.

The purpose was to examine the repetition of non-words that are consistent with the phonotactic patterns of Spanish. The study also examined the relationship between non-word repetition performance and other language measures.

Eleven Spanish-speaking children with Specific Language Impairment and 11 age-matched children with typical language development aged 8;3-10;11, who were part of a larger study of sentence processing, participated in the study. The primary data were the children's repetition of 20 non-words, four at each syllable length (one, two, three, four and five syllables). The children's productions were transcribed and scored for non-word, segmental and cluster accuracy as well as for error type.

The children with Specific Language Impairment performed more poorly on almost all measures of accuracy, but particularly in their production of three-, four-, and five-syllable non-words. Substitutions were the most frequent error type for both groups. Likelihood ratios indicated that non-word repetition performance is a highly accurate identifier of language status in these preselected groups. The children's non-word repetition was highly correlated with most of the standardized language measures that were administered to the children.

The repetition of non-words consistent with Spanish phonotactics reveals word-length effects and error patterns similar to those found in previous studies. It extends these findings to older school-age Spanish-speaking children with Specific Language Impairment. Given the limited choices for instruments that can be used to identify children with Specific Language Impairment, a Spanish Non-word Repetition Task has the potential to be a valuable screening test for clinical and research purposes.
