A Review Of The Effects Of Dietary Restriction, Dehydration, And Caffeine Withdrawal On Cognition: Implications For A Disabled Submarine Scenario, Sarah Chabal
Journal of Human Performance in Extreme Environments
In the event that submariners become trapped aboard a disabled submarine (DISSUB), they must perform a multitude of cognitively demanding tasks in order to maximize their likelihood of survival. During this time, submariners will also be forced to endure poor living conditions, including drastic changes to their nutrition. These nutritional changes have the potential to impair submariners’ cognitive functioning and affect operational performance, which could jeopardize survival; however, the effects of DISSUB nutrition on cognitive performance are not well understood. This review first describes the unique nutritional conditions that submariners will experience in a DISSUB scenario, including the change to …
The Effect That Testing Has On Nondeclarative Memory, David Smith
The Effect That Testing Has On Nondeclarative Memory, David Smith
Electronic Theses and Dissertations
Testing has been shown to improve long-term memory retention by decreasing the amount of material forgotten, a phenomenon known as the testing effect. This positive impact of testing has been shown using direct tests of memory that require declarative memory, things like memorizing word-pairs and single-word lists. This dissertation is the first research to investigate how testing impacts nondeclarative memory using three experiments. The first and second experiment utilize the word fragment completion task to measure the effect that testing has on words learned via methodology thought to recruit either declarative or nondeclarative memory. The third experiment utilizes a probabilistic …
A Whiteheadian Innervation Of The Soma: A New Vision For The Peripheral Nervous System, David Milliern
A Whiteheadian Innervation Of The Soma: A New Vision For The Peripheral Nervous System, David Milliern
Journal of Conscious Evolution
This essay draws attention to two problems in neuroscience’s set of assumptions. These self-defeating assumptions include: 1) the assumption that what the nervous system, especially the brain, does is synthesize experience, while also assuming philosophical realism, and 2) the problem of biological signal transduction. In the latter, neuroscientists and philosophers of biology have left unaddressed the issue that the signal differences between the inside and outside of the organismic boundary are of distinct ontological types; and yet no concern has been expressed regarding how it is possible that an organism’s inner states could reflect the experiential content flowing from outside …
Memory Bias Toward Emotional Information In Burnout And Depression, Renzo Bianchi, Eric Laurent, Irvin Sam Schonfeld, Lucas M. Bietti, Eric Mayor
Memory Bias Toward Emotional Information In Burnout And Depression, Renzo Bianchi, Eric Laurent, Irvin Sam Schonfeld, Lucas M. Bietti, Eric Mayor
Publications and Research
A sample of 1015 educational staff members, exhibiting various levels of burnout and depressive symptoms, underwent a memory test involving incident encoding of positive and negative words and a free recall task. Burnout and depression were each found to be associated with increased recall of negative items and decreased recall of positive items. Results remained statistically significant when controlling for history of depressive disorders. Burnout and depression were not related to mistakes in the reported words, or to the overall number of recalled words. This study suggests that burnout and depression overlap in terms of memory biases toward emotional information.
Microdosing Mindfulness: Understanding The Effects Of Brief Mindfulness Meditation In Children With Adhd, Marcus D. Gottlieb
Microdosing Mindfulness: Understanding The Effects Of Brief Mindfulness Meditation In Children With Adhd, Marcus D. Gottlieb
Electronic Thesis and Dissertation Repository
Mindfulness Meditation (MM) is receiving increased empirical support as a method for addressing ADHD symptomology. Research shows that MM interventions lasting weeks or months promote key aspects of cognitive and psycho-emotional functioning in youth with ADHD. Using a pre-post within-subjects design, we sought to determine whether a single MM session supports neurocognitive and/or psycho-emotional functioning in youth with ADHD. Sixteen participants aged 10-14 completed measures of executive and psycho-emotional functioning before/after a 10-minute MM session and silent reading control. Functional neuroimaging assessed whether MM supported changes in prefrontal cortex (PFC) activation during cognitive tasks. We found that a single MM …
The Biological, Psychological, Cognitive, And Social Perspectives On Aging: The Design Of A Healthy Aging Program For Older Adults, Melissa Santiago
The Biological, Psychological, Cognitive, And Social Perspectives On Aging: The Design Of A Healthy Aging Program For Older Adults, Melissa Santiago
Dissertations
Aging is an inevitable process, accompanied by changes in physiological, cognitive, psychological, and social facets. Researchers have investigated the physiological, cognitive, psychological, and social risk factors associated with aging and have encouraged the use of physical activity, cognitive training, and dietary interventions to alleviate risk factors. However, holistic programs dedicated to promoting successful aging among older adults are uncommon. This review sought to promote successful aging by identifying physiological, cognitive, psychological, and social risk factors that affect older adults and develop a comprehensive program to holistically mitigate these risk factors. Risk factors associated with unsuccessful aging include the development of …
Using Object-Choice Tasks To Investigate Sensory Perception In Sunda Pangolins (Manis Javanica), Joshua Dipaola
Using Object-Choice Tasks To Investigate Sensory Perception In Sunda Pangolins (Manis Javanica), Joshua Dipaola
Theses and Dissertations
Pangolins are one of the most heavily poached, yet least understood mammals in the world. In this study, we used an object-choice task to assess the ecological relevance and use of sensory information in Sunda pangolin foraging behavior. This is the first controlled experiment on pangolin behavior to our knowledge.
Off-Topic Verbosity And Sustained Attention Among Young Adult And Older Adult Age Cohorts, Jessica H. Helphrey
Off-Topic Verbosity And Sustained Attention Among Young Adult And Older Adult Age Cohorts, Jessica H. Helphrey
Psychology and Counseling Theses
Off-topic verbosity (OTV) is tangential discourse with excessive and irrelevant information. Older adults have been historically labeled as having high OTV, and research has suggested that high OTV in older adults may be linked with cognitive decline. While past studies have utilized brief cognitive measures to further expound upon the links between cognition and OTV, studies have lacked consistency and lengthy measures. This study sought to elucidate the relationship between OTV and cognition in both older adult and young adult age cohorts utilizing a sustained attention measure. Young adults (n = 61; age range: 18-28, M = 20.57, SD = …
The Effects Of Verbalizable Features On Category Learning Strategies, Marwan A. Syed
The Effects Of Verbalizable Features On Category Learning Strategies, Marwan A. Syed
Undergraduate Honors Theses
The present study investigated the effects of how verbalizable features (easy vs not-easily) are on category learning strategies with respect to the COVIS model, which states there are two competing systems (verbal and implicit) that operate simultaneously when making categorization decisions. A total of 102 undergraduate students took part in the experiment, which was an A-B categorization task conducted in a video game setting. A rule-based approach reflected the verbal system whereas a family resemblance approach reflected the implicit system. The findings partially support the hypothesis and COVIS model in that participants in the easily verbalizable condition were more likely …

The Project Talent Twin and Sibling (PTTS) study includes 4481 multiples and their 522 nontwin siblings from 2233 families. The sample was drawn from Project Talent, a U.S. national longitudinal study of 377,000 individuals born 1942–1946, first assessed in 1960 and representative of U.S. students in secondary school (Grades 9–12). In addition to the twins and triplets, the 1960 dataset includes 84,000 siblings from 40,000 other families. This design is both genetically informative and unique in facilitating separation of the ‘common’ environment into three sources of variation: shared by all siblings within a family, specific to twin-pairs, and associated with …
