Specific Language Impairment: Evaluation and detection of differential psycholinguistic markers in phonology and morphosyntax in Spanish-speaking children.

Buiza et al. (2016) · Research in developmental disabilities 2016
★ The Verdict

Three quick tasks spot Spanish-speaking kids with SLI as well as longer tests.

✓ Read this if BCBAs in early-intervention or school clinics who assess bilingual children.
✗ Skip if Practitioners working only with English-speaking or non-verbal adults.

01Research in Context

01

What this study did

The team tested 60 Spanish-speaking kids. Half had Specific Language Impairment (SLI). Half were same-age peers with typical language.

Each child completed three quick tasks: repeat a made-up word in a sentence, pick the picture that matches a spoken sentence, and say "pa-ta-ka" as fast as possible for ten seconds.

The goal was to see if this mini battery could flag SLI without long tests.

02

What they found

The three tasks together caught a large share of kids with SLI and correctly cleared a large share of typical kids.

Kids with SLI stumbled most on the made-up word task and the fast "pa-ta-ka" drill. These two items gave the clearest red flags.

03

How this fits with other research

Chou et al. (2010) and Scalzo et al. (2015) also link weak phonology to poor reading in kids with intellectual disability. The new study widens the pattern: phonology problems mark SLI even when IQ is normal.

Poppes et al. (2016) found autistic kids show stagnant phonological working memory. Faso et al. (2016) add that a ten-second oral-motor speed test picks up similar phonology trouble in a different clinical group. The tasks look different but both tap the same underlying bottleneck.

Berument et al. (2005) and Sasson et al. (2022) proved you can adapt screens for deaf or non-verbal adults with ID. This paper does the same for young Spanish speakers—showing good screens travel across languages and ages when you keep them short and concrete.

04

Why it matters

If you serve bilingual families, you now have a five-minute screener that needs no special tools. Use the made-up word task and the "pa-ta-ka" speed drill during intake. A low score tells you to refer for full speech-language testing instead of waiting months. You can also track these two tasks weekly in therapy to see if phonology gains spill over into broader language growth.

03Original abstract

BACKGROUND: The diagnosis of Specific Language Impairment (SLI) is very complex, given the variety of clinical pictures described in this disorder. Knowledge about the linguistic markers of SLI can facilitate its differentiation from the normal profile of language development. These markers can also be used as tools that may improve diagnostic. AIMS: To determine which psycholinguistic markers best discriminate Spanish-speaking children with SLI from children with typical language development. METHOD AND PROCEDURE: The performance of 31 Spanish-speaking children with SLI was analysed using a battery of 13 psycholinguistic tasks organized into two areas: phonology and morphosyntax. The performance of the SLI group was compared to that of two subgroups of controls: aged matched (CA) and linguistically matched (CL). OUTCOMES AND RESULTS: The data show that the SLI group performed worse than the CA subgroup on all 13 verbal tasks. However, the performance of the SLI group did not significantly differ from that of the CL subgroup on most (11/13) of the tasks. Stepwise discriminant analysis established the canonical function of three tasks (morphologic integration, sentence understanding and diadochokinesis) which significantly discriminated SLI from CA, with sensitivity 84% and specificity 90%. CONCLUSIONS AND IMPLICATIONS: These results contribute to determining the psycholinguistic and clinical characteristics of SLI in Spanish-speaking children and provide some methods for screening assessment.
