Neuropsychological Malingering Determination: The Illusion Of Scientific Lie Detection, Chunlin Leonhard, Christoph Leonhard

Georgia Law Review

Humans believe that other humans lie, especially when stakes are high. Stakes can be very high in a courtroom, from substantial amounts of monetary damages in civil litigation to liberty or life in criminal cases. One of the most frequently disputed issues in U.S. courts is whether litigants are malingering when they allege physical or mental conditions for which they are seeking damages or which would allow them to avoid criminal punishment. Understandably, creating a scientific method to detect lies is very appealing to all persons engaged in lie detection. Neuropsychologists claim that they can use neuropsychological assessment tests (Malingering …

The Relationship Between Maternal Emotion Socialization And Child Executive Functioning And Behavior: Exploring The Moderating Role Of Cortisol, Mayela Norwood

CMC Senior Theses

In the early years of life, the development of children’s executive functioning (EF) and behavior regulation are critical to their later growth and self-sufficiency. Previous studies have indicated that one pathway by which children learn to regulate their emotions is through their immediate social environments (de Cock et al., 2017). Parents, in particular, play a significant role in the development of their children‘s emotion regulation and executive functioning (Fernandes et al., 2022). At the same time, physiological responses to stress also matter. Cortisol, the end product of the hypothalamic-pituitary-adrenal axis, has also been associated with children’s executive functioning and behavior …

Cerebellum-Seeded Functional Connectivity Changes In Trait-Anxious Individuals Undergoing Attention Bias Modification Training, Katherine Elwell

All NMU Master's Theses

Anxiety and anxiety related disorders are increasing at a drastic rate in the past decade, with the NIMH reporting that 31.1% of U.S. adults will experience an anxiety disorder at some point in their lives. Anxiety is commonly characterized by increased attention bias to threat. Attention Bias Modification (ABM) is a new treatment used to reduce individual’s attention bias towards threat. The extent to which ABM leads to underlying neural changes is still unknown. The cerebellum is a neglected brain structure, with new research provides evidence that cerebellum’s functional connectivity and shared networks with threat processing regions has a direct …

The Association Of Aerobic Fitness With Resting State Functional Connectivity And Verbal Learning And Memory In Healthy Young Adults, Kyle Joseph Jennette

Theses and Dissertations

The beneficial effects of exercise and cardiopulmonary fitness on general health, quality of life, and reduction of mortality are well known in older adults. There is evidence to support the positive effects of exercise and aerobic fitness on psychiatric and neurocognitive function in children, adults, and older adults. Indeed, many studies have explored the positive effects of aerobic fitness on slowing cognitive decline associated with normal and pathological aging. However, comparatively fewer empirical studies in the literature exist to support and understand the effects of aerobic fitness on the developing brain, particularly during adolescence and young adulthood, especially as it …

Evaluation Of Cognitive Control Using Non-Gaussian Reaction Time Distributions In Fractionated Executive Function Tasks, Dmitriy Kazakov

Theses and Dissertations

The present study seeks to further investigate and refine the three-factor model of executive function (EF; Inhibition, Shifting, and Monitoring/Updating) known as the unity/diversity framework (Miyake et al., 2000). Past work in this area utilized “power” tasks that prioritize accuracy and difficulty, but real-world problem-solving incentivizes quick and efficient solutions. Ten computerized reaction time (RT) tasks: four elementary cognitive tasks (ECTs; Jensen, 1987; Santos, 2016) with progressively increasing task demands and six EF tasks. The ratio scale of RT necessitated the use of non-Gaussian statistics to better describe distribution shape, while diffusion modeling (DM; Ratcliff, 1978) was used to interpret …

Underlying Contribution Of Executive Functioning To Cognition And Academic Achievement In Individuals With Dystrophinopathy, Robert Fee

Dissertations, Theses, and Capstone Projects

Dystrophinopathy is a genetic disorder that results in the lack of or abnormal expression of the protein dystrophin. It is a disorder that alters cell structure and function, impacts the developing brain and brain function, presents with multi-domain cognitive deficits, and influences both mood and behavior. Cognitive impairments appear to be more localized to specific areas of functioning rather than a global deficit; however, deficits have been identified across multiple cognitive domains including language and aspects of executive functioning. A careful examination of the cognitive phenotype and its association to mutations affecting CNS isoforms is necessary to clarify the neuropsychological …

[Introduction To] Well-Grounded: The Neurobiology Of Rational Decisions, Kelly Lambert

Bookshelf

Contingency calculations—the ability to predict the outcomes of decisions and actions—are critical for survival and success. Our amazing brains continually process past and current experiences to enable us to make the most adaptive choices. But when the brain’s information systems are compromised—by such varying conditions as drug addiction, poverty, mental illness, or even privilege—we can lose the ability to arrive at informed decisions.

In this engaging book, behavioral neuroscientist Kelly Lambert explores a variety of the modern factors that can lead to warped neural processing, or distorted realities she terms “brain bubbles.” Individuals who define success in terms of creature …

The Effects Of Cognitive Rehabilitation For Improving Prospective Memory In Acquired Brain Injury, Emily M. Aiken

Masters Theses

Acquired Brain Injury (ABI) includes any damage to the brain resulting from traumatic (e.g. motor vehicle accident) or non-traumatic (e.g. stroke) incidence, that occurs after birth and is not resulting from genetic or congenital factors. Individuals with ABI report that prospective memory (PM) deficits are the most detrimental cognitive impairment following injury, persistently and negatively impacting their ability to function properly in everyday life. PM refers to the ability to remember to carry out intended tasks in the future, including the recall of both time and event regulated intentions. Using neuropsychological assessments to produce patient deficit profiles, this study examines …

Relationships Between Age And White Matter Integrity In Children With Phenylketonuria, Erika M. Wesonga

Arts & Sciences Electronic Theses and Dissertations

Objective: Phenylketonuria (PKU) is a hereditary metabolic disorder associated with cognitive compromise. Diffusion tensor imaging (DTI) has allowed detection of poorer microstructural white matter integrity in children with PKU, with decreased mean diffusivity (MD) in comparison with healthy children. However, very little research has been conducted to examine the trajectory of white matter development in this population. The present study investigated potential differences in the developmental trajectory of MD between children with early- and continuously-treated PKU and healthy children across a range of brain regions.

Methods: Children with PKU (n = 31, mean age = 12.2 years) were …

A Preliminary Investigation Of The Validity Of Time-Based Measures Of Sustained Attention For Children, Michael R. Kulfan

Antioch University Full-Text Dissertations & Theses

This study is a preliminary investigation of the validity of using time-based measures to quantify sustained attention in children ages 6-12. Problems with sustained attention negatively affect childhood learning and development. The prevalence of disorders known to impact sustained attention performance continue to rise in the United States. Currently, commercially available, objective measures of sustained attention use normative comparisons that provide limited information about the effect such problems have on child performance in natural settings. We reviewed test data from 290 charts of children ages 6-12 referred for neuropsychological evaluation. The Test of Everyday Attention for Children (TEA-Ch) is an …

Neurocognitive Deficits And Functional Outcome In Bipolar Disorder, Danielle T. Bello

UNLV Theses, Dissertations, Professional Papers, and Capstones

Bipolar disorder affects approximately 1% of the population. It is a severe and debilitating illness, causing serious impairment of interpersonal, occupational and social functioning. The disorder is characterized by marked mood swings as well significant neurocognitive deficits. Based on work with other psychiatric and neurological disorders, neurocognitive deficits in bipolar disorder are expected to be strong predictors of functional capacity. However, few studies have evaluated the consequences of neurocognitive deficits in this disorder. Most available studies have focused on the clinical correlates of functional outcome, such as number of hospitalizations, age of disorder onset, and severity of symptoms. While useful, …
