Bilingual language development is a common experience across the globe with an estimated 50% of the world’s children growing up exposed to more than one language (Crystal, 2003). Thus, it seems logical that our discussion of supporting children with complex communication needs includes children who grow up in bilingual and multilingual environments. Evidence from the literature related to bilingual language development in typically developing children points to no substantial negative effects of bilingual language development and possible cognitive advantages (Bialystok et al., 2009).
However, this raises the question, whether the same is true for children with linguistic and cognitive impairments. After all, if children with language impairments struggle with learning one language, wouldn’t learning two languages be even more challenging and possibly confusing? In recent years, researchers in speech-language pathology and related disciplines have begun to address this question. The majority of research on bilingual children with developmental disabilities has focused on children with specific language impairment (SLI) which by definition, excludes children with intellectual disability (e.g., Leonard, 2014). However, several studies have included children with autism spectrum disorders (ASD) and Down syndrome (DS).
Children with SLI who are raised in a bilingual environment, demonstrate difficulties in learning both languages but numerous studies indicate that these linguistic difficulties are similar to monolingual peers with language impairments (e.g., Gutiérrez-Clellen et al., 2008; Paradis, Crago, & Genesee, 2006; Paradis, Crago, Genesee, & Rice, 2003). Studies of bilingual children with ASD reveal similar findings to those of bilinguals with SLI. Several studies found that bilingual and monolingual children with ASD demonstrated similar language skills. (Hambly & Fombonne 2012; Ohashi et al., 2012; Petersen, Marinova-Todd, & Mirenda, 2012; Valicenti-McDermott et al., 2012).
Less is known about the bilingual language abilities of children with cognitive impairments, and many practitioners and parents are concerned about the ability of children with low cognitive abilities to learn to speak two languages. These concerns are understandable, given that children with cognitive disorders typically have difficulty learning language. However, emerging evidence indicates that bilingually-exposed children with DS demonstrate similar patterns of bilingual language use when compared with monolingual children with DS (Feltman & Kay-Raining Bird, 2008; Kay-Raining Bird, Cleave, Trudeau, Thordardottir, Sutton, & Thorpe, 2005).
Research to date provides a clear narrative that overall bilingual children with linguistic and cognitive impairments are not significantly more impaired than monolingual peers with language impairment. However, bilingual language experiences are widely different and individual variability in degree and quality of exposure to a second language can greatly influence a child’s language outcomes. Current understanding of bilingual language development in children with linguistic impairments is still in its infancy, and more research is critically needed. Because adverse effects on the family, community, and cultural interactions have been documented in families when parents abandon speaking their native language to their children with disabilities, it is important that speech-language pathologists provide accurate advice to parents and other professionals such as doctors and educators.

Many teachers require their college students in communication disorders or child development classes to complete a Communication Matrix online. Please have your students use the Test Drive site for this purpose. You may ask them to print out the Profile and Communication Skills List as proof of their work.
The only way I know that he wants something is because he fusses or whines when he's unhappy or uncomfortable, and he smiles, makes noises or calms down when he's happy and comfortable. Does this statement describe your child?
She doesn't come to me to let me know what she wants, but it's easy for me to figure out, because she tries to do things for herself. She knows what she wants, and her behavior shows me what she wants. If she runs out of something to eat, she will just try to get more, rather than trying to get me to give her more.
Does this statement describe your child?
He knows how to get me to do something for him. He uses some of the kinds of behaviors below to communicate:
Does this statement describe your child?
Each question you will see is related to a certain message that your child might be able to express using a variety of behaviors. Read the question and decide whether your child is able to express the message described using any of the listed behaviors. If the answer is YES, then you must also decide whether your child has mastered the use of each behavior or whether it is still at an emerging stage. Check either the mastered or emerging box next to any behaviors your child uses to express the message. Use the following definitions to decide whether a behavior is mastered or emerging
– Does this independently most of the time when the opportunity arises
– Does this in a number of dierent contexts, and with dierent people
– Does this inconsistently
–
Only does this when prompted or encouraged to do so. Only does this in one or two contexts or with one person.
