The Effect Of A Voice Treatment On Facial Expression In Parkinson’S Disease: Clinical And Demographic Predictors, 2018 The Graduate Center, City University of New York
The Effect Of A Voice Treatment On Facial Expression In Parkinson’S Disease: Clinical And Demographic Predictors, Amanda D. Bono
All Dissertations, Theses, and Capstone Projects
Parkinson’s disease (PD) is a neurodegenerative disease associated with a wide range of motoric, cognitive, and behavioral symptoms. Impairments in facial mobility and emotional expressivity are common and can impair communication, in turn, affecting daily functioning and quality of life. Previous research suggests that the Lee Silverman Voice Treatment © (LSVT LOUD; Ramig et al., 2001, 2011) increases vocal loudness and facial expressivity in individuals with PD compared to PD and healthy controls. This study extends the literature by examining the effects of LSVT and an articulation-based control treatment (i.e., ARTIC) on multiple aspects of facial expressivity (i.e ...
Functional Polymorphisms Of Alcohol Metabolism Genes And Their Protection Against Alcoholism Via Gene Therapy: A Systematic Review, 2018 University of Arkansas, Fayetteville
Functional Polymorphisms Of Alcohol Metabolism Genes And Their Protection Against Alcoholism Via Gene Therapy: A Systematic Review, Olivia Tzeng
Psychological Science Undergraduate Honors Theses
Around 45% of East Asians are unable to fully metabolize ethanol due to functional
polymorphisms of alcohol metabolism genes, specifically alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH). These individuals display high levels of toxic blood acetaldehyde when consuming alcohol, causing symptoms such as tachycardia, vomiting, and flushing. The studies included in this review examine how functional polymorphisms of ADH and ALDH protect against alcoholism in addition to how polymorphisms can be utilized as protection against alcoholism via gene therapy. The studies included found that carriers of the ADH and ALDH polymorphisms were 66 to 99% genetically protected against alcoholism. Through ...
The Immediate And Long-Lasting Cognitive Consequences Of Adolescent Chronic Sleep Restriction, 2018 Seton Hall University
The Immediate And Long-Lasting Cognitive Consequences Of Adolescent Chronic Sleep Restriction, Kerry Howard
Seton Hall University Dissertations and Theses (ETDs)
Adolescence is a critical developmental period. An important change that occurs in adolescence is the neurological maturation for adult-type cognitive abilities. Research has linked adequate sleep quantity to successful learning and memory capabilities. However, due to a shift in sleep timing drive in adolescence, in combination with early awakening for school, the adolescent population is experiencing chronic sleep restriction (CSR). What repercussions to long-term memory capabilities could CSR in adolescence have immediately and are the consequences long-lasting? The present study modeled human adolescent CSR in rats through four hours of sleep deprivation for five days, followed by two days of ...
Attentional Sub-Processes Involved With Emotional Eating, 2018 University of New Orleans
Attentional Sub-Processes Involved With Emotional Eating, Gregory Denke
University of New Orleans Theses and Dissertations
Emotional eating behavior is characterized by eating a large amount of calorie dense sweet and/or high fat foods in an attempt to control, cope with, or avoid negative emotions. Numerous factors are likely to contribute to emotional eating behavior, including attentional factors, such as rumination and avoidance coping. Rumination based emotional eating (attention focused on negative stimuli while mindlessly eating) is often utilized to improve mood while dwelling on problems. However, for those inclined to escape/avoid troublesome thoughts, another type of emotional-eating pattern may be used. By focusing attention on food, emotional eating is believed to distract individuals ...

Treating Adhd With Suggestion: Neurofeedback And Placebo Therapeutics, 2018 McGill University
Treating Adhd With Suggestion: Neurofeedback And Placebo Therapeutics, Robert T. Thibault, Samuel Vassière, Jay A. Olson, Amir Raz
Psychology Faculty Articles and Research
Objective: We propose that clinicians can use suggestion to help treat conditions such as ADHD. Methods: We use EEG neurofeedback as a case study, alongside evidence from a recent pilot experiment utilizing a sham MRI scanner to highlight the therapeutic potential of suggestion-based treatments. Results: The medical literature demonstrates that many practitioners already prescribe treatments that hardly outperform placebo comparators. Moreover, the sham MRI experiment showed that, even with full disclosure of the procedure, suggestion alone can reduce the symptomatology of ADHD. Conclusion: Non-deceptive suggestion-based treatments, especially those drawing on accessories from neuroscience, may offer a safe complement and potential ...
Literature Review And Proposal: Yoga As Group Exercise Involving Oxytocin Release For Positive Mood Improvement, 2018 Bowling Green State University
Literature Review And Proposal: Yoga As Group Exercise Involving Oxytocin Release For Positive Mood Improvement, Rachel Fenton
A literature review discusses yoga and health involving oxytocin creates the premise for a proposal combining the knowledge of yoga and its health benefits along with oxytocin's potential involvement during group exercise, yoga specifically. The proposed study's results of oxytocin measures and questionnaires have the potential to develop an understanding of the possible impacts of yoga on mood, particularly relationships between group exercise and yoga, which may help develop forms of group exercise or implement group yoga to assist or replace treatment for stress-caused or stress-related disorders.
Effort-Related Decision Making In Comt Variant Mice: Pharmacological Studies And Genetic Susceptibility To Motivational Dysfunction, Suzanne Cayer
Honors Scholar Theses
Effort-related decision making tasks in animals can model motivational symptoms in humans, which are a set of symptoms spanning a multitude of neuropsychiatric disorders, such as major depressive disorder and the negative symptoms of schizophrenia. The present studies aimed to evaluate the effort-related effects of the Val158Met polymorphism of human catechol-methyltransferase (COMT), by testing mice carrying either the human COMT Val (n=8) or Met allele (n=8) with Wild-Type control mice (n=15) by using concurrent FR2 and FR4/pellet choice tasks in a touchscreen operant conditioning apparatus. The Val158Met polymorphism has been repeatedly associated with neuropsychiatric disorders, and ...
The Convergence Of Psychology And Neurobiology In Flavor-Nutrient Learning, 2018 Bucknell University
The Convergence Of Psychology And Neurobiology In Flavor-Nutrient Learning, Kevin P. Myers
Faculty Journal Articles
Flavor evaluation is influenced by learning from experience with foods. One main influence is flavor-nutrient learning (FNL), a Pavlovian process whereby a flavor acts as a conditioned stimulus (CS) that becomes associated with the postingestive effects of ingested nutrients (the US). As a result that flavor becomes preferred and intake typically increases. This learning powerfully influences food choice and meal patterning. This paper summarizes how research elucidating the physiological and neural substrates of FNL has progressed in parallel with work characterizing how FNL affects perception, motivation, and behavior. The picture that emerges from this work is of a robust system ...
Biological Signatures Of Emotion Regulation In Children, 2018 The Graduate Center, City University of New York
Biological Signatures Of Emotion Regulation In Children, Sarah Myruski
All Dissertations, Theses, and Capstone Projects
Emotion regulation (ER) is a key predictor of positive adjustment throughout the lifespan. Despite decades of research on discrete ER strategy use, ER may be more appropriately measured in terms of the breadth of emotional range, or the degree to which one can flexibly modulate emotional responses. Yet little is known about ER flexibility in childhood. Also, given the crucial role of caregiver support in children’s emotional lives, ER may be most accurately measured in developmentally appropriate and ecologically valid social contexts. Further, few developmental studies have capitalized on the growing evidence base surrounding biological signatures of ER. This ...
Characterizing The Role Of Glucocorticoids In The Sign Tracking Behavior Of Male Japanese Quail (Coturnix Japonica), 2018 University of Kentucky
Characterizing The Role Of Glucocorticoids In The Sign Tracking Behavior Of Male Japanese Quail (Coturnix Japonica), Beth A. Rice
Theses and Dissertations--Psychology
A devastating feature of drug-dependence is the susceptibility of relapse (40-60%) after stretches of abstinence. One theory that may account for relapse suggests that drug cues (e.g., paraphernalia) may increase stress hormones, and this may prompt relapse. Repeatedly pairing a neutral cue with a reward is commonly utilized to measure what subjects learn about a cue that is predictive of reward. Research has shown that animals that attend to a cue more than to the reward (sign trackers) may be more vulnerable to drug addiction. Additionally, research has shown that sign tracking is associated with an increase in corticosterone ...
Assessment Of Peripheral Bndf Levels Over 30 Days, 2018 Humboldt State University
Assessment Of Peripheral Bndf Levels Over 30 Days, Sally Hang
Theses and projects
Brain health, and the benefits of exercise have been linked to the biological signaling molecule called brain-derived neurotrophic factor (BDNF). Animal and human studies have provided some support for physical exercise as a mechanism for increasing BDNF levels. However, results have been inconsistent, which may be attributed in part to incomplete information about normal variation in circulating peripheral BDNF levels. This investigation examined capillary-drawn whole blood samples from nine healthy adult participants over 30 days with the goal of documenting variability in resting BDNF levels and changes that may be attributed to physical exercise. It was hypothesized that BDNF concentrations ...
Investigating Differing Degrees Of Foxo3a Expression In Adult Neural Stem Cells Between Age Groups In Zebrafish, 2018 Humboldt State University
Investigating Differing Degrees Of Foxo3a Expression In Adult Neural Stem Cells Between Age Groups In Zebrafish, Francis G. Bacik
Theses and projects
One factor influencing organismal longevity is the activity of transcription factors of the “fork head domain” family, otherwise known as “Forkhead box” (Fox) proteins. Studies of the four isoforms of the “O” subclass of Fox proteins found in human genes have revealed a direct relationship between FoxO3a-dependent gene expression and the conservation of neural stem cell (NSC) in the adult brain, specifically in the subgranular zone of the dentate gyrus in the hippocampus and the subventricular zone of the cortex. This transcription factor has also been shown to regulate apoptosis in nervous tissue during embryonic development in zebrafish. The current ...
Social Contact Patterns Can Buffer Costs Of Forgetting In The Evolution Of Cooperation, 2018 University of Nebraska-Lincoln
Social Contact Patterns Can Buffer Costs Of Forgetting In The Evolution Of Cooperation, Jeffrey R. Stevens, Jan K. Woike, Lael J. Schooler, Stefan Lindner, Thorsten Pachur
Jeffrey Stevens Papers & Publications
Analyses of the evolution of cooperation often rely on two simplifying assumptions: (i) individuals interact equally frequently with all social network members and (ii) they accurately remember each partner's past cooperation or defection. Here, we examine how more realistic, skewed patterns of contact—in which individuals interact primarily with only a subset of their network's members—influence cooperation. In addition, we test whether skewed contact patterns can counteract the decrease in cooperation caused by memory errors (i.e. forgetting). Finally, we compare two types of memory error that vary in whether forgotten interactions are replaced with random actions ...
The Signature Of Undetected Change: An Exploratory Electrotomographic Investigation Of Gradual Change Blindness, 2018 University of Nebraska-Lincoln
The Signature Of Undetected Change: An Exploratory Electrotomographic Investigation Of Gradual Change Blindness, John E. Kiat, Michael D. Dodd, Robert F. Belli, Jacob E. Cheadle
Faculty Publications, Department of Psychology
Neuroimaging-based investigations of change blindness, a phenomenon in which seemingly obvious changes in visual scenes fail to be detected, have significantly advanced our understanding of visual awareness. The vast majority of prior investigations, however, utilize paradigms involving visual disruptions (e.g., intervening blank screens, saccadic movements, “mudsplashes”), making it difficult to isolate neural responses toward visual changes cleanly. To address this issue in this present study, high-density EEG data (256 channel) were collected from 25 participants using a paradigm in which visual changes were progressively introduced into detailed real-world scenes without the use of visual disruption. Oscillatory activity associated with ...
Network Approaches To Understand Individual Differences In Brain Connectivity: Opportunities For Personality Neuroscience, 2018 University of Pennsylvania
Network Approaches To Understand Individual Differences In Brain Connectivity: Opportunities For Personality Neuroscience, Steven Tompson, Emily B. Falk, Jean M. Vettel, Danielle S. Bassett
Departmental Papers (ASC)
Over the past decade, advances in the interdisciplinary field of network science have provided a framework for understanding the intrinsic structure and function of human brain networks. A particularly fruitful area of this work has focused on patterns of functional connectivity derived from noninvasive neuroimaging techniques such as functional magnetic resonance imaging (fMRI). An important subset of these efforts has bridged the computational approaches of network science with the rich empirical data and biological hypotheses of neuroscience, and this research has begun to identify features of brain networks that explain individual differences in social, emotional, and cognitive functioning. The most ...
Chickens Play To The Crowd, 2018 University of Trieste, Department of Life Sciences
Chickens Play To The Crowd, Cinzia Chiandetti
The time was ripe for Marino’s review of chickens’ cognitive capacities. The research community, apart from expressing gratitude for Marino’s work, should now use it to increase public awareness of chickens’ abilities. People’s views on many animals are ill-informed. Scientists need to communicate and engage with the public about the relevance and societal implications of their findings.

Faculty Publications, Department of Psychology
Despite literature revealing the adverse consequences of objectifying gazes for women, little work has empirically examined origins of objectifying gazes by perceivers. Integrating alcohol myopia and objectification theories, we examined the effects of alcohol as well as perceived female attractiveness, warmth, and competence on objectifying gazes. Specifically, male undergraduates (n = 49) from a large U.S. Midwestern university were administered either an alcoholic or placebo beverage. After consumption, participants were asked to focus on the appearance or personality (counterbalanced) of pictured women who were previously rated as high, average, or low in attractiveness, warmth, and competence. Replicating previous work, appearance ...
Effort-Related Motivational Dysfunctions: Behavioral And Neurochemical Studies Of The Wistar-Kyoto Rat Model Of Depression, 2018 University of Massachusetts Amherst
Effort-Related Motivational Dysfunctions: Behavioral And Neurochemical Studies Of The Wistar-Kyoto Rat Model Of Depression, Brendan Abbott
Depression and related disorders are characterized by motivational dysfunctions, including deficits in behavioral activation and exertion of effort. Animal models of relevance to depression represent a critical starting point in elucidating the neurobiological mechanisms underlying motivational dysfunctions. The present study explored the use of the Wistar-Kyoto (WKY) animal model of depression to examine effort-related functions as measured by voluntary wheel running and performance on a mixed fixed ratio 5/progressive ratio (FR5/PR) operant task. Given the known link between activational aspects of motivation and the mesocorticolimbic dopamine (DA) system, the behavioral effects of d-amphetamine (0.5 and 1.0 ...
Sentience In Fishes: More On The Evidence, 2018 East Tennessee State University
Sentience In Fishes: More On The Evidence, Michael L. Woodruff
In my target article, I argued that the brains of ray-finned fishes of the teleost subclass (Actinopterygii) are sufficiently complex to support sentience — that these fishes have subjective awareness of interoceptive and exteroceptive sense experience. Extending previous theories centered on the tectum, I focused on the organization of the fish pallium. In this Response to the commentaries, I clarify that I do not propose that the fish pallium is, or must be, homologous to the mammalian neocortex to play a role in sentience. Some form of a functionalist approach to explaining the neural basis of sentience across taxa is probably ...
