*Előadás a BME Kognitív Tudományi Központ* *házi kollokvium sorozata keretében:* *Előadó: **Laurence B. Leonard (Purdue University)* *Cím:* *The Crosslinguistic Study of Children with Specific Language Impairment* *Absztrakt:* Children with specific language impairment (SLI) show a significant deficit in their language ability but appear to be functioning normally in other areas. Their hearing is normal, they earn age-appropriate scores on nonverbal tests of intelligence, they do not show symptoms characteristic of autism, and they exhibit no clear signs of neurological impairment. Children with SLI who are acquiring English often experience a mild to moderate deficit in vocabulary and sentence length but a more serious deficit in the use of grammatical morphology (e.g., saying /Mommy like eat ice cream /instead of /Mommy like*s to *eat ice cream/). The purpose of this presentation is to show that a clear understanding of this profile, or other profiles of SLI, requires careful study of SLI across languages. Examples will be presented of very different symptoms of SLI depending on the type of language (e.g., English, Swedish, Italian, Cantonese) being acquired. Implications for language treatment will also be discussed. *Idő:* 2004 szeptember 30 (*kivételesen csütörtök*), 16 óra *Hely:* BME, St. 320. Minden érdeklődőt szeretettel várunk. Jakab Zoltán
