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). …

A Novel Use Of The Deese-Roediger-Mcdermott Paradigm: Distinguishing Between Differential Memory Mechanisms In Emotional Literature, Alan John Yablonski Jr.

Senior Honors Projects, 2010-2019

To current knowledge, the emotional literature has not included the proposal to conceptualize experimental designs in terms of item vs. hippocampal-dependent relational memory representations. Through utilizing the Deese-Roediger-McDermott (DRM) paradigm the current study targets two memory mechanisms: item-specific memory (i.e., font color) and relational memory. In addition, relational-binding memory was also assessed. The current study consists of three hypotheses: (a) negatively-valenced critical lures will be correctly recalled by participants more than neutrally-valenced critical lures (increased relational memory for negatively-valenced words), (b) participants will more accurately recall studied negatively-valenced words with the correct color compared to neutrally-valenced studied words (increased item-specific …

Eye Movement Effects In Simulated Object Recognition Memory Impairment, Dmitriy Kazakov

Theses and Dissertations

Malingering is the purposeful fabrication of symptoms for secondary gain. Memory problems are the most reported symptom, and object recognition tests are often used in clinical settings to evaluate these claims. Past research has shown that eye movements can indirectly index memory, in that greater viewing is directed at studied stimuli 500-750 ms after display onset. The present study evaluated eye movements as a potential method of detecting feigned memory impairment. Forty-eight participants, half simulators, studied standardized images and took a memory test. Several levels of analysis were used to detect broad trends and brief effects. Simulators performed significantly worse …

Reduced Conscious Recollection And Its Detection In Three Performance Validity Tests : A Dual Task Interference Investigation, Graham Michael Silk-Eglit

Legacy Theses & Dissertations (2009 - 2024)

Performance validity is an essential component of neuropsychological assessment. Research suggests that examinees with specific neurological conditions cannot successfully complete certain performance validity tests (PVTs). However, very little basic research has explored the information processing underlying performance on PVTs that might explain why these examinees fail certain PVTs. The current study used a dual task interference paradigm to isolate the impact of reducing conscious recollection on the performance of three PVTs, the Test of Memory Malingering (TOMM), Victoria Symptom Validity Test (VSVT), and Word Memory Test (WMT). One-hundred-and-twenty-six non-clinical undergraduate research participants were administered these three PVTs as part of …

Comparative Memory/Behavioral Symptoms Of Alzheimer's Disease: Eoad Vs. Load, Marcia Gale Roberson

Walden Dissertations and Doctoral Studies

Alzheimer's disease (AD) is a fatal disorder with no apparent cure. Early-onset AD (EOAD) occurs in individuals before the age of 65, and late-onset AD (LOAD) occurs in individuals age 65 and older. Past studies have proven that AD is fatal among Americans age 65 and older. The disease is characterized by impairments in memory and executive function as well as other cognitive and behavioral problems. The research questions addressed by this sequential, mixed-method study compared EOAD and LOAD by exploring common behavioral/cognitive symptoms and stage levels of AD. Research participants were recruited from the Alzheimer's Association who were members …
