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 …

Mental Disorders As Brain Disorders: The Impact On Stigma Of Neuroscience-Based Mental Health Education, Katherine Tighe
Honors Theses
Stigmatization of mental illness is undoubtedly detrimental to those with mental health concerns as it limits employment, self-esteem and social support (Markowitz, 1998). In effort to combat the issue of stigma, previous research has evaluated the effectiveness of education as a method to reduce stigma in a college sample; finding that peer-led presentations are effective in reducing stigma (Kosyluk et al., 2016). The current study sought to evaluate the effectiveness of neuroscience-oriented presentation for reducing the stigma of mental illness among college students. Researchers asked 53 Union College students to complete seven-item Social Distance Scale (SDS; Penn et al., 1994) …

Vmpfc Activation During A Stressor Predicts Positive Emotions During Stress Recovery, Xi Yang, Katelyn M. Garcia, Youngkyoo Jung, Christopher T. Whitlow, Kateri Mcrae, Christian E. Waugh
Psychology: Faculty Scholarship
Despite accruing evidence showing that positive emotions facilitate stress recovery, the neural basis for this effect remains unclear. To identify the underlying mechanism, we compared stress recovery for people reflecting on a stressor while in a positive emotional context with that for people in a neutral context. While blood–oxygen-level dependent data were being collected, participants (N = 43) performed a stressful anagram task, which was followed by a recovery period during which they reflected on the stressor while watching a positive or neutral video. Participants also reported positive and negative emotions throughout the task as well as retrospective thoughts …

Discrepant input from vestibular and visual systems may be involved in motion sickness; individual differences in the organization of these systems may, therefore, give rise to individual differences in propensity to motion sickness. Non-right-handedness has been associated with altered cortical lateralization of vestibular function, such that non-right-handedness is associated with left hemisphere, and right-handedness with right hemisphere, lateralized, vestibular system. Interestingly, magnocellular visual processing, responsible for motion detection and ostensibly involved in motion sickness, has been shown to be decreased in non-right-handers. It is not known if the anomalous organization of the vestibular or magnocellular systems in non-right-handers might alter …
Neural Hypervigilance In Trauma-Exposed Women,

Neural Hypervigilance In Trauma-Exposed Women, Seungyeon A. Yoon
Dissertations, Theses, and Capstone Projects
Trauma-exposed people often experience hypervigilance, which is a tonic condition of elevated alertness and excessive scanning for potential threat. A cardinal feature of hypervigilance is that no actual threat is needed to evoke or maintain the over-alertness and heightened affective response. However, most neuroimaging research in trauma to date has only focused on reactivity to an actual threat. Thus, the overarching aim of this dissertation was to investigate neural signatures and salivary markers of post-trauma hypervigilance in the absence of threat that can cause impairment in daily functioning and contribute to developing other trauma-related symptoms such as heightened threat reactivity. …
Biological Signatures Of Emotion Regulation In Children,

Biological Signatures Of Emotion Regulation In Children, Sarah Myruski
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 study …

We live in a world where awareness of ethnic and cultural diversity is an ever increasing reality. Business and education turn to the social sciences to inform them about how to manage and optimize cross-cultural interactions. Although much research has been done on the impact of cross-cultural interactions on a wide range of variables, one less researched area is the endocrine response to cross-cultural interactions. In this study we set out to investigate the endocrine response to cross cultural interactions and the impact of these interactions on perceived differences. To do so we measured the pre and post levels of …

Occupational health psychology (OHP) is a cross-disciplinary subspecialty within psychology. OHP derives from two disciplines within applied psychology, health psychology and industrial/organizational psychology. OHP is also linked to disciplines outside of psychology, such as occupational medicine and public health. The discipline has roots in eighteenth, nineteenth, and twentieth century thinkers, including Adam Smith, Friedrich Engels, Karl Marx, Émile Durkheim, and Max Weber. These thinkers were concerned with the impact of the organization of work and the business cycle on human life. Later research by Elton Mayo, Marie Jahoda, Walter B. Cannon, Hans Selye, and investigators at the University of Michigan’s …

Chickens Play To The Crowd, Cinzia Chiandetti
Animal Sentience
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.

The Effect Of Early Life Photoperiod Manipulation On Cocaine-Induced Behavioral Sensitization In Male And Female Japanese Quail, Shannon Elizabeth Eaton
Theses and Dissertations--Psychology
Estrogens seem to play a role in the locomotor activating effects of cocaine. Japanese quail provide a good model for hormonal manipulation as alterations of their photoperiod controls hormone levels. The current study aims to examine the role of early life photoperiod manipulation in cocaine-induced behavioral sensitization in quail. It was expected that if quail were raised on a short photoperiod, they would have a reduction in gonadal hormones and this reduction in hormones would affect the acquisition of cocaine-induced behavioral sensitization. Quail were raised on an 8L:16D or a 16L:8D light cycle. Following 2 days of habituation, quail were …

Potential Candidates For Treating Deficits Associated With Developmental Ethanol Exposure In A Rodent Model: Solidago Nemoralis & Dimethoxybenzylidene-Anabasine, Logan James Fields
Theses and Dissertations--Psychology
Prenatal alcohol exposure (Fetal Alcohol Syndrome [FAS] and Fetal Alcohol Spectrum Disorders [FASD’s]) represents the leading preventable cause of intellectual disabilities in the western world, with FASDs estimated to affect approximately 2-5% of live births in the United States at an approximate annual cost of $3.6 billion (CDC, 2015; May et al., 2009). Ethanol (ETOH) exposure during development can lead to a variety of long-term behavioral impairments including problems with executive functioning, motor coordination, spatial learning, attention, and hyperactivity (Jones, 2011; Mattson & Riley, 1998). Much research has been conducted to develop pharmacological and/or environmental interventions to reduce these deficits, …

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 (CORT), …

Insulin Modulates The Strong Reinforcing Effects Of Nicotine And Changes In Insulin Biomarkers In A Rodent Model Of Diabetes, Bryan Cruz
Open Access Theses & Dissertations
This study examined whether the strong reinforcing effects of nicotine and changes in insulin biomarkers observed in diabetic rats are modulated via insulin. A model of diabetes was employed involving administration of streptozotocin (STZ), which produces hypoinsulinemia in rats. The present study included vehicle- or STZ-treated rats that received sham surgery or an insulin pellet. Two-weeks later, the rats were given extended access to intravenous self-administration (IVSA) of saline or nicotine. Concomitant changes in food intake, water responses, and body weight were assessed during 12 days of IVSA. After the last session, plasma levels of insulin, leptin, amylin, and glucagon-like …

Burnout Syndrome And Depression, Renzo Bianchi, Irvin Sam Schonfeld, Eric Laurent
Publications and Research
In this chapter, we proposed an overview of burnout, from the introduction of the construct in the mid-1970s to the growing realization that the syndrome was better conceived of as a depressive condition. Recent studies have shown that the distinction between burnout and depression is problematic, both theoretically and empirically. The history of burnout research suggests that transdisciplinary communication and methodological standards should be strengthened to avoid the proliferation of constructs that, in fact, refer to the same phenomena. Construct proliferation, a transgression of the scientific canon of parsimony, is considered a major problem today because it undermines theory building …

Modeling The Psychiatric Aspects Of Polycystic Ovary Syndrome And Induced Stress, Danielle Peecher
All Master's Theses
Polycystic ovary syndrome (PCOS) is an endocrine disorder in women that is characterized by excess testosterone and is associated with increased risk of infertility. Women with PCOS also show higher rates of depression and anxiety. Modeling PCOS in mice via administration of dihydrotestosterone (DHT) results in physiological alterations that are consistent with the physiological symptoms of PCOS in women. While some studies have investigated behavioral changes in PCOS mouse models, findings have varied. Thus, the current research examined whether a PCOS model with an additional stress factor resulted in behavioral changes. To create a stress condition, subjects were implanted with …

Effects Of Social Interaction On Morphine Conditioned Place Preference In Adolescent Male Rats, Virginia G. Weiss
Theses and Dissertations--Psychology
The fact that adolescents commonly initiate drug use in social settings is well established. Both clinical and preclinical research has investigated how social interaction is altered by a variety of drugs of abuse. What is less understood is how the rewarding value of drugs of abuse is affected by the presence of social peers. This dissertation aimed to investigate the interaction of morphine and social play on conditioned place preference (CPP) in adolescent male Sprague Dawley rats, using both behavioral and immunohistochemistry (IHC) methods. Rats were exposed to morphine (0, 1, or 3 mg/kg; s.c.), social interaction, or a combination …

The Impact Of Neonatal Pain And Reduced Maternal Care On Brain And Behavioral Development, Sean Michael Mooney-Leber
Wayne State University Dissertations
In the neonatal intensive care unit (NICU) preterm infants are exposed to a multitude of stressors, which include both neonatal pain and reduced maternal care. Clinical and preclinical research has demonstrated that exposure to neonatal pain and reduced maternal care has a profound negative impact on brain and behavioral development. Currently, the biological mechanism by which both of these stressors impacts brain and behavioral outcomes remains widely unknown. To uncover a potential biological mechanism, the current dissertation project utilized a preclinical model of repetitive needle pokes and developed a novel model of reduced maternal care through tea-ball encapsulation. Briefly, rat …

Do Different Music Genres Differentially Affect Autonomic Activity? How Music And Sound Affect Autonomic Activity Aroused By Visual Stimuli, Andrew Manson
Online Theses and Dissertations
The primary researcher sought to determine whether different genres of music would differentially influence measures of autonomic nervous system activity (heart rate, galvanic skin response) while viewing visual stimuli in a sample of college students. All participants listened to the same songs and music genres and viewed the same International Affective Picture System (IAPS) images. Autonomic nervous system activity was recorded by attaching electrodes to participants' non-dominant hand and torso. Music order presentation and picture order presentation were randomly determined by E-Prime. Heart rate and skin conductance responses were both significant, with melodic metal music inducing greater intensity of responses …

Sentience In Fishes: More On The Evidence, Michael L. Woodruff
Animal Sentience
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 …
