Assessing Working Memory In Mild Cognitive Impairment With Serial Order Recall, Sheina Emrani
Assessing Working Memory In Mild Cognitive Impairment With Serial Order Recall, Sheina Emrani
Theses and Dissertations
Background: Working memory (WM) is often assessed with serial order tests such as repeating digits backward. In prior dementia research using the Backward Digit Span subtest (BDT) only aggregate test performance was examined. The current research tallied primacy/ recency effects; out-of-sequence transposition errors; perseverations and omissions to assess WM deficits in patients with mild cognitive impairment (MCI). Methods: Memory clinic patients (n= 66) were classified into three groups - single domain amnestic MCI (aMCI), combined mixed domain/ dysexecutive MCI (mixed/dys MCI), and non-MCI where patients did not meet criteria for MCI. Serial order/ WM ability was assessed by …
Emotion Regulation In Relation To Cognitive Functioning In The Preclinical Stages Of Dementia, Erica P. Meltzer
Emotion Regulation In Relation To Cognitive Functioning In The Preclinical Stages Of Dementia, Erica P. Meltzer
Dissertations, Theses, and Capstone Projects
Emotion regulation (ER) is essential for effective functioning in daily life. Research suggests that ER improves in older adulthood despite concomitant declines in cognition and the presumed neural substrates of ER. The current understanding of ER in older adulthood, and particularly of the relationship between ER and cognition in older adulthood, is limited. This is likely because the construct of ER is challenging to operationalize and, therefore, difficult to study.
The current study investigates ER in relation to cognitive functioning, specifically executive functioning and memory, in individuals with varying degrees of cognitive difficulties (i.e., in the preclinical stages of dementia). …
Age Differences In Bimanual Coordination, Paul Amrhein, George Stelmach, Noreen Goggin
Age Differences In Bimanual Coordination, Paul Amrhein, George Stelmach, Noreen Goggin
Department of Psychology Faculty Scholarship and Creative Works
A bimanual coordination experiment was conducted in which two groups of 10 male and female participants, elderly (67 to 75 years of age) and young (21 to 25 years of age), produced unimanual, bimanual symmetrical (equal extent amplitude), and bimanual asymmetrical (unequal extent amplitude) movements. In addition to an overall increase in performance latency, the elderly group exhibited a linear increase in response initiation (RT) with increases in task complexity similar to that of the young group. However, the elderly participants showed a proportional increase over the young participants in response execution latency (MT). Further, the elderly group had a …
