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 »
Families of bilingual children with developmental language disorder (DLD) are often told to use only one language. School district personnel may insist that these children receive instruction in only one language even if there are bilingual programs available. Even bilingual personnel who work with children (teachers and SLPs for example) may say that children with DLD can become more confused if in a bilingual environment. This is simply not true. I have participated in many studies that demonstrate that bilingual children are not more likely to show higher risk for DLD than monolinguals; we know that bilingual children with DLD show comparable performance to monolingual children with DLD; we know that bilingual children with DLD show cognate advantages similar to typical bilinguals; we know that intervention in one language can carry over to the other language. This work is all supported by the data-based research (linked) and is consistent with work that other researchers are doing. Read the rest of this entry »
Cognates are really interesting words that share meaning and sound the same across languages. Languages that share the same roots also have a large number of cognates because of their shared histories. Spanish and English share a large number of cognates.
We’ve studied cognate recognition in young children. In that study of kindergarten and first grade children, we found that Spanish dominant children and English dominant children scored similarly on a receptive vocabulary test given in English. But, they showed different patterns of response. Those who were Spanish dominant were more likely to know the cognates– even those that were above their age level. English dominant kids tended to know non-cognates. So, consistent with other studies, we found a cognate advantage for Spanish-speaking children learning English as a second language. In a recent study, we were interested in whether bilingual children with DLD would show a similar cognate advantage. Read the rest of this entry »
We’ve (as a field) have known for about 20 years that single word vocabulary tests whether they are receptive or expressive tests are poor indicators of developmental language disorders (DLD). At the same time, these tests are very often used by SLPs as part of a diagnostic. They are easy to give, quick, and highly reliable. It’s hard to make an error in administration or scoring on these tests. But, reliability is not enough (neither are the other reasons). Even if it only takes 5 minutes and the score is a perfect representation of what the child can do it doesn’t mean that a low score indicates impairment or that a high score indicates typical development. As far as domains of language go– children with DLD do pretty well with vocabulary at the single word level. It’s semantics (connections among words) that they have difficulty with.

I keep hearing these stories and it’s infuriating! There’s no evidence that bilingualism is confusing and no evidence that bilingualism makes developmental language disorder worse so stop it! Read the rest of this entry »
You know I’m gonna say no. But, it’s important to establish what does happen and to do so with data. After several studies we have enough data to look at this question more carefully with a set of children with developmental language disorder (aka: language impairment; specific language impairment; or primary language impairment) who had varying levels of exposure to Spanish and English.

While acquiring language, children show a tendency to use function words with a very high frequency compared to content words. These high frequency words are referred to as core vocabulary words, a term frequently used in AAC. These include pronouns, prepositions, conjunctions, articles, auxiliary verbs, modals, indefinites, as well as content words including adverbs, but few nouns or verbs. Function words provide speakers a bridge to combine words to increase their utterance length. You can think of these as the glue that binds together grammar and vocabulary. This “glue” is important and are used across different kinds of contexts including conversations and story-telling. They are used across many contents including work, school and home.
We were interested in understanding how children with language impairment (LI) use these core vocabulary words. We wanted to know which core words they used; if patterns were different in each language; and if children with language impairment used these same core words as often as those with typical development.
So, in a recent longitudinal study we looked at use of core vocabulary words in Spanish-English bilingual children with and without LI. We analyzed 30 core vocabulary words in Spanish and English narrative samples of children in kindergarten and again in first grade. Children with LI produced fewer core vocabulary words and used them less frequently compared to their typically developing (TD) peers. This difference was more pronounced in first grade.
One lesson we can draw from this is that children with LI have much more sparse vocabulary as compared to their typical peers consistent with previous findings. What was unexpected was that they also use core words much less often than their TD peers. While this does not mean that intervention should focus on, for example, the articles “the” “la” or “el” in therapy. Or at least not exclusively. But, it is important to think about how these core vocabulary words supports learning of the content words (such as nouns). It may be important to teach content words in phrases rather than in isolation so that the core words are reinforced. These can also serve as “frames” to teach other content words. As children progress we can continue to help them to link together learned phrases into sentences and conversation. So, as you work with children with language impairment, don’t forget about the glue that holds it all together.
I belong to a Facebook group SLPs for Evidence Based Practice. There is frequent discussion of what works and what doesn’t in intervention and in assessment. My work has often focused on assessment and assessment practices. And, I have to say that it is frustrating to find that something does (or doesn’t) work but that clinical practices take so long to change. So, I wonder what is our obligation in the field to be aware of the evidence? And what is our obligation to make changes in our practices? Read the rest of this entry »
I’ve been asked this question a couple of times now, the most recent was a few days ago, so I thought I’d write about it here. The bottom line is YES, WITH TRAINING. But, let me explain. Read the rest of this entry »
A question that often comes up about our research is how to apply it clinically. Much of our work is motivated by clinical questions and ultimately we aim to have some clinical solutions. It’s hard sometimes to move directly from research to application. Sometimes the clinical questions we pose have no or very little research available to move to the next step. So, we have to step back and do the more basic descriptive work to understand the nature of bilingualism and of bilingual impairment before we can then more forward again to answer questions about assessment and treatment. Now that we’ve done more work that has implications for assessment and have the BESA available for clinicians we can start to think about more direct application.
I wrote a year ago that we can get the most accurate indicator of language impairment on the BESA when we combine the best language across domains. So, we might combine Spanish morphosyntax with English semantics for a language composite. But, how do you write up results to incorporate into a report?
In a fairly recent paper, we provide some illustrations of how to use test information to make clinical decisions using the BESA. We go through the parent and teacher interview we use to determine possible concern about speech and language ability in each language and how we determine language use and exposure. Finally, we demonstrate how we combine and compare Spanish and English performance across each domain to determine language impairment. I hope these help in writing up your clinical reports.
