[P3–435]: WORKING MEMORY DEFICITS IN STATISTICALLY DETERMINED MILD COGNITIVE IMPAIRMENT: A COMPETITIVE CUEING ANALYSIS

Abstract:

Background Working memory (WM) is a neurocognitive mechanism whereby information is kept active for brief periods. WM is often assessed with serial ordering tests, ie, repeating digits forward/backward. Two mechanisms comprise competitive queuing (CQ) models of WM;(1) parallel planning whereby elements for recall are initially activated; and (2) competitive choice whereby salient items are chosen for recall. CQ models of WM are supported with an examination of primacy/recency effects, transposition errors (disparity between a response and its correct serial position), and items errors including perseverations/omissions. The current research tested how CQ WM constructs can differentiate patients with subtle cognitive impairment (SCI) versus mild cognitive impairment (MCI). Methods Jak, Bondi et al.,(2009) criteria was applied to a protocol of tests and categorized participants into three groups: single domain …
