The Effect Of Grapes In Mice With Alzheimer's Disease And Brain Injury, Nikita Mistry
Loma Linda University Electronic Theses, Dissertations & Projects
Alzheimer’s disease (AD) is a progressive neurodegenerative disorder resulting in cognitive and memory deficits and deposits of amyloid beta (Aβ) in the cortex and hippocampus are thought to be significant contributors to the disease process. Increasing evidence suggests that foods rich in polyphenols, such as pomegranates and grapes, may have neuroprotective effects in both rodents and humans. Our previous research has shown that a pomegranate-enriched diet decreased Aβ plaque load and improved behavior in Tg2576 mice. In this study, we determined whether a grape-enriched diet altered Aβ neuropathology and TBI in PSAPP mice. Mice received either craniotomy or a moderate …

Does Video Game Use Exacerbate The Relation Between Neurophysiological Deficits And Adhd Symptoms In Children And Adolescents?, James Kenneth Goodlad Iii
Dissertations
Attention-deficit/hyperactivity disorder (ADHD) is diagnosed based on behavioral symptoms but is thought to have a significant heritable neurological basis, and several brain structures have been implicated. Recent research has focused on the role of environmental factors that may influence the behavioral expression of inattention and hyperactivity-impulsivity in children and teens, particularly when a biological predisposition exists. This study sought to broaden the literature base by examining the extent to which one environmental factor—video game use—moderated the relation between neuropsychological deficits in attention and inhibition and the behavioral symptoms of ADHD. It was hypothesized that gaming frequency and duration as well …

The Phenomenon Of Abstract Cognition Among Scholastic Chess Participants: A Case Study, Brent C. Laws
Electronic Theses and Dissertations
A qualitative investigation was conducted to explore the phenomenon of abstract cognition among a purposive sample of 5 secondary scholastic chess club participants. The case study enabled the researcher to explore the faculties of abstract cognition among students of contrasting skills and abilities in playing chess. The study also allowed for the consideration of potential visual-spatial, logical, academic, social competency and life benefits of chess play. Through analysis of interviews, chess simulations, blindfold chess play, and narration of chess lines and sequences, the investigator was able to extract meaning and code schemata into a holistic understanding of the phenomenon of …
Utilizing Visual Attention And Inclination To Facilitate Brain-Computer Interface Design In An Amyotrophic Lateral Sclerosis Sample,

Utilizing Visual Attention And Inclination To Facilitate Brain-Computer Interface Design In An Amyotrophic Lateral Sclerosis Sample, David B. Ryan
Electronic Theses and Dissertations
Individuals who suffer from amyotrophic lateral sclerosis (ALS) have a loss of motor control and possibly the loss of speech. A brain-computer interface (BCI) provides a means for communication through nonmuscular control. Visual BCIs have shown the highest potential when compared to other modalities; nonetheless, visual attention concepts are largely ignored during the development of BCI paradigms. Additionally, individual performance differences and personal preference are not considered in paradigm development. The traditional method to discover the best paradigm for the individual user is trial and error. Visual attention research and personal preference provide the building blocks and guidelines to develop …

Change Detection In Rhesus Monkeys And Humans, Deepna T. Devkar, Deepna T. Devkar
Dissertations and Theses (Open Access)
Visual working memory (VWM) is the temporary retention of visual information and a key component of cognitive processing. The classical paradigm for studying VWM and its encoding limitations has been change detection. Early work focused on how many items could be stored in VWM, leading to the popular theory that humans could remember no more than 4±1 items. More recently, proposals have suggested that VWM is a noisy, continuous resource distributed across virtually all items in the visual field, resulting in diminished memory quality rather than limited quantity. This debate about the nature of VWM has predominantly been studied with …

Factor Structure Of The Cpt-Ii, Mary Vertinski
UNLV Theses, Dissertations, Professional Papers, and Capstones
The current study investigates the factor structure of the Conners' Continuous Performance Test-II (CPT-II) in four pediatric samples of participants: (a) patients with traumatic brain injury, (b) healthy controls, (c) patients with various clinical diagnoses, and (d) all of the previously mentioned subjects combined. Confirmatory factor analyses (CFA) were used to investigate a one-, three- and four-factor model fit of the data. None of the models examined were an adequate fit for the data; however, it appears that the four-factor model seemed to be the best fitting of the models examined. Failure to find reasonably adequate fit precluded further analyses.

Longer Gestation Among Children Born Full Term Influences Cognitive And Motor Development, Emma V. Espel, Laura M. Glynn, Curt A. Sandman, Elyssia Poggi Davis
Psychology Faculty Articles and Research
Children born preterm show persisting impairments in cognitive functioning, school achievement, and brain development. Most research has focused on implications of birth prior to 37 gestational weeks; however, the fetal central nervous system continues to make fundamental changes throughout gestation. Longer gestation is associated with reduced morbidity and mortality even among infants born during the period clinically defined as full term (37–41 gestational weeks). The implications of shortened gestation among term infants for neurodevelopment are poorly understood. The present study prospectively evaluates 232 mothers and their full term infants (50.4% male infants) at three time points across the first postnatal …
Reliability Of Eyewitness Reports To A Major Aviation Accident,

Reliability Of Eyewitness Reports To A Major Aviation Accident, Dave English, Michael Kuzel
International Journal of Aviation, Aeronautics, and Aerospace
There is a paucity of studies on the reliability of eyewitness reports to aviation crashes. We examine witness statements to a widely observed major airline accident to determine if reported accident investigator distrust of details in eyewitness reports is supported by empirical evidence. The extensive archival witness record (N > 300) of a wide-body airliner crash in clear daylight conditions is subjected to statistical analysis to test eyewitness reliability. Even with over 200 witnesses within a three square kilometre (1.6 square mile) area answering a binary observation question, the variance is sometimes high enough to preclude forming statistically significant conclusions …
Positive Affect Facilitates Task Switching In The Dimension Change Card Sort Task: Implications For The Shifting Aspect Of Executive Functions,

Positive Affect Facilitates Task Switching In The Dimension Change Card Sort Task: Implications For The Shifting Aspect Of Executive Functions, Hwajin Yang, Sujin Yang
Research Collection School of Social Sciences
Using the modified Dimensional Change Card Sort task, we examined the influence of positive affect on task switching by inspecting various markers for the costs, including restart cost, switch cost and mixing cost. Given that the executive-control processes that underlie switching performance—i.e., inhibition or shifting—are distinct from the component processes that underlie non-switching performance—i.e., stimulus evaluation, resource allocation or response execution—we hypothesised that if positive affect facilitates task switching via executive-control processes, rather than via component processes, positive affect would reduce both switch and restart costs, but not mixing cost, because both switch and restart costs rely on executive processes, …

“Me & My Brain”: Exposing NeuroscienceʼS Closet Dualism, Liad Mudrik, Uri Maoz
Psychology Faculty Articles and Research
Our intuitive concept of the relations between brain and mind is increasingly challenged by the scientific world view. Yet, although few neuroscientists openly endorse Cartesian dualism, careful reading reveals dualistic intuitions in prominent neuroscientific texts. Here, we present the “double-subject fallacy”: treating the brain and the entire person as two independent subjects who can simultaneously occupy divergent psychological states and even have complex interactions with each other—as in “my brain knew before I did.” Although at first, such writing may appear like harmless, or even cute, shorthand, a closer look suggests that it can be seriously misleading. Surprisingly, this confused …

Mixed-Case Format And Lexical Decision Performance: Initial Uppercase Is Special, Julia C. Harvey Azzolina, Lois M. Rotuno, April D. Butler Waltonen, Albert F. Smith
Undergraduate Research Posters 2014
Previous research has shown that there are phenomena that may require a route to word identification by means other than through letters. For example, in a lexical decision task, in which an experimental participant is asked to determine if a string of letters is a word or not, responses to items in a MIXed caSE format are slower than to items in PURE UPPERCASE or pure lowercase formats. In this experiment, we investigated the effect of different mixed-case formats on lexical decision performance, focusing on the type and location of the case transition. Twenty-four students participated in a lexical decision …
Public Management In Political Institutions: Explaining Perceptions Of White House Chief Of Staff Influence,

Public Management In Political Institutions: Explaining Perceptions Of White House Chief Of Staff Influence, José Villalobos, Justin Vaughn, David Cohen
Selected Works Temporary Series
The notion that public managers influence organizational performance is common in public administration research. However, less is known about why some managers are better at influencing organizational performance than others. Furthermore, relatively few studies have systematically examined managerial influence and scholars have yet to investigate either quantitatively or systematically managerial influence in the White House. Utilizing original survey data collected from former White House officials who served in the Reagan, George H.W. Bush, and Clinton administrations, this study applies empirical public management theory to examine for the first time the key determinants that shape perceptions of chief of staff managerial …

Kinematic Effects In Large Transport Aircraft, Shem Malmquist, Dennis A. Vincenzi Ph.D., Dahai Liu Ph.D.
International Journal of Aviation, Aeronautics, and Aerospace
The control of an aircraft relies on sensory feedback. It follows that any aspect that could create a situation where that feedback is faulty can lead to unintended outcomes. The size of very large jet aircraft can result in kinematic effects that impact the perceptions of the flight crew. Due to the large amount of inertia involved, coupled with aerodynamic factors, when the aircraft pitch (θ) is initially changed, the short term actual motion of the aircraft, as viewed from the center of gravity, remains relatively unchanged. As a consequence of aircraft design, this results in the flight deck changing …
The Use Of Hemifield Eye-Patching For Modifying The Perceptual-Attentional Bias In Healthy Individuals,

Seton Hall University
The Use Of Hemifield Eye-Patching For Modifying The Perceptual-Attentional Bias In Healthy Individuals, Randall L. Miller
Seton Hall University Dissertations and Theses (ETDs)
Healthy individuals do not perceive the left and right sides of space equally, showing a leftward spatial bias on visuospatial tasks. This bias may be more attributed to a perceptual-attentional (PA) component than a motor-intentional (MI) component. While monocular eye patching alters this spatial bias via modification of PA but not MI, hemifield eye patches that occluded the left or right half of the visual field have been shown to be more effective at modifying spatial bias, but only in patients with spatial neglect. Furthermore, it is unclear whether hemifield patching affects PA, MI, or both. The goal of the …

Prism Adaptation Effects On The Attentional Window, Michelle C. Rosenthal
Seton Hall University Dissertations and Theses (ETDs)
Prism adaptation, a visuomotor adaptation procedure that employs a lateral shift of the visual field, has been widely shown to affect lateral biases in the distribution of spatial attention in healthy individuals. The effects of prism adaptation on the size of the attentional window, the limited area of the visual field we attend to and extract information from without moving our eyes, are not fully elucidated. In this study, I investigated the effects of prism adaptation on the size of the attentional window in healthy young adults. This was accomplished via a useful field of view task, which measures the …

Alternate Forms Reliability For Written Expression Probes, Ashley Carey
Masters Theses & Specialist Projects
The use of Curriculum-Based Measurement (CBM) in schools continues to increase, as it is a useful brief assessment of students’ basic academic skills. CBM measures are used for multiple tasks such as identifying students at-risk, creating local norms, monitoring students’ progress during interventions, and assisting with special education eligibility determinations. Much of the research has focused on CBM in the areas of math and reading. Relatively few studies have examined the area of CBMWritten Expression. Even fewer studies exist exploring the reliability among alternate writing forms. This study determined alternate form reliability coefficients for written expression probes at the second, …

Short-Term Visual Deprivation, Tactile Acuity, And Haptic Solid Shape Discrimination, Charles E. Crabtree
Masters Theses & Specialist Projects
The visual cortex of human observers changes its functionality in response to visual deprivation (Boroojerdi et al., 2000). Behavioral studies have recently documented enhanced tactile abilities following a short period of visual deprivation (Facchini & Aglioti, 2003; Weisser, Stilla, Peltier, Hu, & Sathian, 2005). The current study investigated the effects of visual deprivation on two unique tactile tasks. While Facchini and Aglioti observed significant effects of visual deprivation, neither Wong, Hackeman, Hurd, and Goldreich (2011) nor Merabet et al. (2008) observed these effects. Corroborating these more recent results, no difference in grating orientation discrimination performance was observed between the sighted …
Visual Cues Effects On Temperature Perception,

Visual Cues Effects On Temperature Perception, Carrie Anne Balcer
All NMU Master's Theses
The purpose of this study was to measure reaction times (RTs) when a conflict arises between the visual feedback and the temperature of an object. This study focused on the quantifiable RTs along with the qualitative feedback of the participants. It was hypothesized that when the information of the visual and temperature stimuli are incongruent (blue-warm or red-cold), the RTs will be slower than when they are congruent (blue-cold or red-warm). We suggest that vision could convey temperature perception in an independent but complimentary manner. We utilized the Oculus Rift to create a virtual environment that allowed us to control …
