The types of intrusion errors (Prior List, Semantically Related, and Unrelated)
made on the LASSI-L verbal memory task were compared across three diagnostic groups
(N = 160, 61 % female), Cognitively Normal (CN), amnestic Mild Cognitive Impairment
(aMCI), and Alzheimer’s disease (AD). Errors related to Proactive, Recovery from
Proactive, and Retroactive Interference were also analyzed, as well as the relationship of
errors to Amyloid load, a biomarker of AD. Results suggest that the types of error made
indicated the level of cognitive decline. It appears that as deficits increase, impaired
semantic networks result in the simultaneous activation of items that are semantically
related to LASSI-L words. In the aMCI group, providing a semantic cue resulted in an
increased production of Semantically Related intrusions. Unrelated intrusions occurred
rarely, although, a small number occurred even in the CN group, warranting further
investigation. Amyloid load correlated with all intrusion errors. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2018. / FAU Electronic Theses and Dissertations Collection
