For a long time, many of us have worked on development of better assessment methods for bilingual children. We know that many of the measures normed for monolinguals are not appropriate for bilinguals. We know that translated measures can lose their psychometric properties because difficulty may shift in translation. But, in the last 20 years there have been more measures and procedures that are validated for Spanish-English bilinguals. Work on other language pairs is emerging as well, but right now the majority of available measures focus on Spanish-English.Read the rest of this entry »
I think the title says it all, and it’s an important question. There’s no doubt that the best way to determine if a child has a language impairment is to test them in their language. For bilinguals, that usually means two languages– in the US context, their home language and English. But, there aren’t enough bilingual speech-language pathologists available nationally; and bilingual speech-language pathologists don’t speak every language represented by the clients in their area. So, one of the questions we’ve had is whether we can get any useful information from testing children who are bilingual in English only. The quick answer is yes, no, and it depends. The longer answer follows. Read the rest of this entry »
Last June, I gave a keynote on dynamic assessment at SRCLD and presented recently analyzed data using DA with bilingual kindergarteners. We are currently in the process of writing the paper on this and hope to submit it soon for publication. If all goes well with the review and revision process maybe in a year it’ll be accepted and then a few months after that before it is available. Meanwhile however, we’re not the only ones to take on this question. So, here’s a summary of what I’ve found recently. Read the rest of this entry »
I got into research in part because I was curious in lexical organization in bilinguals and in bilingual language impairment. Sometimes I feel like I’ve gotten distracted doing other kinds of work. So, it’s kinda fun to get back to something that I feel has gotten neglected.
How do children learn and organize their vocabulary? As children learn new words, they have to compare them with the words they already know. Words might sound the same but have different meanings (e.g., hoarse vs. horse). They also can compare words by category (e.g., chair, sofa) and function (e.g., cup, drink). These comparisons help children to make associations among words, and this helps children build their vocabulary knowledge. For bilinguals, it’s not so different, but the comparisons are made within languages and across languages. Across languages, children need to make connections among words that sound the same and have the same (e.g., velocity, velocidad) and different (e.g., contest, contestar (answer)) meanings. Bilinguals need to associate translation equivalents (e.g., dog, perro). And they need to keep word classes (e.g., nouns, verbs, adjectives) straight within each language.
