Specific Language ImpairmentCurrent LectureReceptive vs. Expressive Language- Receptive: Ability to understand the domains of language- Expressive: The ability to speak or use the domains of language- In typically developing children, the ability to understand a certain part of language (reception) always comes before the ability to produce or use it (expression). Differences vs. Delays vs. Disorders- Differenceso Variations of a symbols system used by a group o Reflect regional, social, cultural, or ethnic differences- Delayso Child is developing receptive and expressive language skills in typical ORDER but at a slower rate- Disorderso Child is producing unusual language forms, not seen in typically developing children These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Developmental vs. Acquired- Developmental Language Impairmento No known biological or cognitive cause- Acquired Language Impairmento The result of or secondary to: syndrome, health condition, injury or illness after birth Assessment- Case History – Birth, developmental, medical historyo Looking for birth complications, primary deficits or medical issues that might leadto language disorders; check developmental milestones- Hearing Evaluation o Assess structures and functions of hearing system- Oral Peripheral Examinationo Assess structures and functions of speech system - Formal Language Testing & Language sampling and analysiso Evaluate the 5 domains of language (Phonology, Morphology, Syntax, Semantics, Pragmatics)o Determine which are are impaired o Characterize abilities and weaknessesCommon Language Impaired Populations- Late Talkerso Early Delay in language in the absence of cognitive, motor, sensory, social, emotional disorders, or environmental deprivationo Usually identified around age 2o 10-15% of 2 year olds are late talkerso Characteristics: Small expressive vocabulary, delayed onset of speech, failure to combine words into phrases and sentences, delayed acquisition of phonemes and morphemes Children with strong gestural and play skills and good receptive language usually catch up- Specific Language Impairmento “significant limitations in language functioning not attributed to deficits in hearing, oral structure & function, or general intelligence.” o SLI is usually identified not by its characteristics, but by RULING OUT other disorders – there is a persistent language deficit with no other deficits or identifiable causes o They have normal IQ, with low verbal IQ o 7% of children ages 3-5o Not diagnosed until age 4 to differentiate late-talkerso Cause? genetic predisposition toward SLI (runs in families); documented brain differenceso Characteristics delayed motor skills and clumsiness delayed expressive language skills difficulty with syntax & morphology - especially pronouns, verb tense, complex and compound sentences; sound immature semantic problems - weaker word knowledge, smaller vocabulary; difficulty remember words produces more word errors Although friendly and, often have trouble making and keeping friends; socially
