Peripheral biomarkers and brain behavior, structure, and function in healthy, aging adults
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2024-08-01

Evaluating the cognitive benefits associated with an acting intervention: A brain-behavior framework
… the configuration of large-scale functional brain networks with a corresponding decline in higher-order cognitive function. These cognitive changes can often compromise the ability to function independently. Previous research has suggested that the aging brain exhibits plasticity, and that …

The relationship of self-regulation and academic achievement in college students with and without attention-deficit/hyperactivity disorder: a brain-behavior perspective
… of self-regulation, (b) self-regulation behaviors, and (c) academic achievement in college students with and without ADHD.

The Effects of Multiple-Intervention Neurofeedback on Engineering Design Ideation
… the ideation phase of engineering design. Brainstorming is identified as a dominant method for ideation, relying on cognitive processes linked to memory. Neuro-cognitive feedback is introduced as a technique to maintain high cognitive responses during ideation by providing information about …

Resting-State Cerebral Perfusion Patterns: An Exploratory Factor Analysis of Single-Photon Emission Computed Tomography Clinical Data
… with psychopathology but have not studied brain-behavior assessment with the potential of application of neuropsychological assessment of psychopathology. SPECT may offer a cheaper, faster, and more accessible option for detecting psychopathology, increasing public access to mental …

Executive Functioning Outcomes among Self-Harming Adolescents Receiving DBT-A
… and discussed implications for treatment and brain-behavior relationships. Ninety-three adolescents from a 16-week DBT-A program for DSH were administered the BRIEF-SR at baseline and post-treatment. There was improvement from the at-risk to non-clinical range on the Emotional Control, Shift, …

The neural correlates of social and non-social decision-making in resolving complex, dynamic uncertainty
… networks. The second study extended this design behaviorally, examining the structure and variability of hypothesis generation across individuals. The third study manipulated appraisals directly, instructing participants to assess the informativeness of scenes in relation to a guilt hypothesis. …

Magnetic Resonance Imaging Movies for Multivariate Analysis of Speech
… yet relatively unexplored, means to study brain-behavior relationships. Fortunately, magnetic resonance imaging (MRI), which has been proven to characterize soft tissue excellently, has recently become a promising technique for the study of speech. MRI\'s contributions in speech research …

Behavioral and neurological investigations into pathological gambling as a behavioral addiction
… focused on integrating neurological and behavioral levels of analysis in the context of pathological gambling. A thoroughgoing analysis on previous gambling research was explored and discussed in the first four chapters. Specifically, this analysis outlines: similarities between …

Ready for Action! When the Brain Learns, Yet Memory-Guided Behavior Does Not Follow
… to events in the present, the magnitude of behavioral benefit varies and can even be absent. How is it that the brain learns, yet the learning does not influence memory-guided action? In this thesis, I show that 1) not all learned memory representations are usable for behavior and 2) those …

The impact of two spatial strategies on entorhinal and hippocampal involvement in visual path integration
… to a point of origin. Findings from in-lab behavioral testing (n = 50) showed that neither strategy elicited more accurate path integration performance than the other, and that gender/sex moderated strategy use. Specifically, male configural updaters outperformed female configural updaters …

Delay Discounting as a Transdiagnostic Neural Phenotype
… demonstrate a symptom-specific link to a neurobehavioral dimension across psychiatric disorders. In particular, my work focuses on delay discounting, one of the recommended measures for brain-behavior phenotyping in transdiagnostic research. Delay discounting involves choosing between a smaller …

Bayesian Tensor Modeling of High-Dimensional Neuroimaging Data
… insights into structural and functional brain changes. Techniques such as magnetic resonance imaging (MRI), positron emission tomography (PET), and diffusion tensor imaging (DTI) generate high-dimensional data that can be used to identify biomarkers indicative of disease progression. …

Neural correlates of trait mindfulness
There is a clear and present need to identify the brain biological bases of mental health and mental illness. In this thesis, I focus on the brain bases of trait mindfulness, measured using self-report. Mindful individuals pay attention to the present moment and bring an attitude of acceptance and …

Disentangling neural heterogeneity in autism
… functional connectivity (FC) within and between brain areas. A complementary theory suggests that atypical functional communication in autism could result from an altered ratio between excitatory and inhibitory input (E:I imbalance). These theories have been previously explored as they might …

The effects of environmental switchovers between enrichment and impoverishment on brain and behavior in mice
… than have the less consistent changes in behavioral tendencies. The specific nature of environmentally induced modifications in behavioral tendencies must be better understood, if substantive predictions about brain-behavior relationships can be made. Furthermore, the long-term effects of …

Exploring the fathering brain: insights from neural activation
Organisms require a great deal of behavioral plasticity to accomplish the tasks associated with reproduction. In addition to day-to-day activities, breeding animals must establish a territory, find a mate, find a place to raise offspring, mate and rear offspring. While organisms are breeding, they …

Effects of Regional Deletion of Rab3A-interacting Molecule and PTEN on Brain Function
… from targeted neuronal populations to study brain region-specific behavioral functions. To this end, I utilized two different conditional knockdown techniques to study the role of the presynaptic active zone molecule Rab3A-interacting Molecule (RIM1) and the phosphatase and tensin homologue …
