The Taxi driver Test

Why the change? The language we use can affect the services that Children receive Can’t do research without common definitions

Questions we need to answer • Which children should get extra help? • Audit: how many SALTs do we need? • Is rate of language problems increasing/decreasing over time? • How do different countries/region compare? • What causes children’s language problems? Adapted from D Bishop March 2018

SLCN DLD e.g. e.g. speech ASC sound disorders 7.6% • verbal learning / memory • syntax • semantics • word retrieval • pragmatics • phonology e.g. language e.g. genetic conditions difficulties acquired such as cerebral palsy after brain injury

Biomedical conditions • Language disorder associated with known genetic condition (e.g. Down syndrome, Klinefelter syndrome) • Acquired brain injury • Sensorineural hearing loss • *Intellectual disability • *Autism spectrum disorder * Included because growing evidence of genetic basis for these conditions 58 Adapted from D Bishop March 2018

What is new? • Developmental language disorder (DLD) to replace SLI • Disorder defined in terms of functional impairment and poor prognosis • Rather than exclusionary factors, ‘Language disorder associated with X’ – also need assessment/intervention • Does not use invalid delay/disorder distinction • Does not use social background as criterion • Does not use nonverbal IQ as criterion • Additional disorders as descriptor rather than exclusionary factor 51 Adapted from D Bishop March 2018
