Multilevel Discourse Processing Analyses in Adults with a Cognitive Impairment

摘要: Participants with a cognitive impairment associated Alzheimer's disease (AD) present discourse impairments early within the disorder. These are declines in episodic, semantic, and working memory. provide researchers opportunity to examine linguistic other systems responsible for discourse, as well determine how impact discourse. Moreover, since these often qualitatively quantitatively different from healthy aging, may be able use multilevel analysis improve screening methods impairment. The purpose of this study, then, is two-fold: (1) participants AD fit into construction-integration model processing special attention given role semantic memory have on (2) if can discriminate between controls. include 12 controls matched age education. To assess abilities, complete three tasks: tasks, tasks. task will measures episodic Wechsler Memory Scale - III. tasks involved Pyramid Palm Tree Tests, Boston Naming Category Flunecy Test. require tell story two wordless pictures books. samples were analyzed micro- macrolinguistic errors; percentage living things; light verbs; thematic elements actions. For study aim one, MANOVA determined that produced more errors, fewer actions compared two, binary logistic regression correctly grouped 87.5% their correct group. While promising, research needed understand has whether or not used method.
