PSY315H5 Lecture Notes - Lecture 7: Specific Language Impairment, Nicaraguan Sign Language, Language Disorder
Document Summary
Non-proficient users: haven"t mastered the language. Input that"s going into young children"s ear is input from non-proficient speakers: not the normal input in the language learning scenario in that context. What is the consequence: children seem to often surpass their parents, behave as if input they got is regular. Defects seem to be passed over in the course of acquisition. Can"t be sure that children aren"t getting exposure to language outside the home. Difficult to isolate the effects to the adults. Idea that parent"s are the sole source is probably wrong. Parents learned asl from their community and videotapes. Characterized by inconsistent patterns (way they express certain kinds of meaning) Characterized by a deficit in language abilities; leaves other aspects of cognition unaffected: parents were the only source of asl. Notion of a blueprint: some basic idea of how language is supposed to look, maybe blueprint isn"t supposed to be specific. Going beyond what his parent"s are doing.
