Butterfly Eyespots: Their Potential Influence On Aesthetic Preferences And Conservation Attitudes, Zoi Manesi, Paul A. M. Van Lange, Thomas V. Pollet

Research Collection School of Social Sciences

Research has shown that the mere presence of stimuli that resemble eyes is sufficient to attract attention, elicit aesthetic responses, and can even enhance prosocial behavior. However, it is less clear whether eye-like stimuli could also be used as a tool for nature conservation. Several animal species, including butterflies, develop eye-like markings that are known as eyespots. In the present research, we explored whether the mere display of eyespots on butterfly wings can enhance: (a) liking for a butterfly species, and (b) attitudes and behaviors towards conservation of a butterfly species. Four online experimental studies, involving 613 participants, demonstrated that …

Traditional Grain Alcohol (Bai Jiu, 白酒) Production And Use In Rural Central China: Implications For Public Health, Ling Qian, Ian M. Newman, Wen Xiong, Yanyu Feng

Department of Educational Psychology: Faculty Publications

Background: An estimated 25 % of the alcohol consumed in China is traditional unrecorded alcohol produced and distributed informally. Consequently there is concern about its safety and its contribution to public health risk. Little has been written about this type of alcohol in China.

Methods: Researchers observed the manufacture of traditional bai jiu in a rural area of Hubei Province, Central China. Two hundred fifty-nine individuals were interviewed, either individually or in small groups, about their use of and attitudes toward bai jiu. Individuals who made or sold bai jiu were interviewed about local production, distribution, and sale. Key community …

The Corpus Callosum In Primates: Processing Speed Of Axons And The Evolution Of Hemispheric Asymmetry, Kimberley A. Phillips, Cheryl D. Stimpson, J. B. Smaers, Mary Ann Raghanti, B. Jacobs, A. Popratiloff, Patrick R. Hof, Chet C. Sherwood

Psychology Faculty Research

Interhemispheric communication may be constrained as brain size increases because of transmission delays in action potentials over the length of axons. Although one might expect larger brains to have progressively thicker axons to compensate, spatial packing is a limiting factor. Axon size distributions within the primate corpus callosum (CC) may provide insights into how these demands affect conduction velocity. We used electron microscopy to explore phylogenetic variation in myelinated axon density and diameter of the CC from 14 different anthropoid primate species, including humans. The majority of axons were less than 1 µm in diameter across all species, indicating that …

Differentiated Effects Of The Multimodal Antidepressant Vortioxetine On Sleep Architecture: Part 2, Pharmacological Interactions In Rodents Suggest A Role Of Serotonin-3 Receptor Antagonism, Steven C. Leiser, Deborah Iglesias-Bregna, Ligia Westrich, Alan Pehrson, Connie Sanchez

Department of Psychology Faculty Scholarship and Creative Works

Antidepressants often disrupt sleep. Vortioxetine, a multimodal antidepressant acting through serotonin (5-HT) transporter (SERT) inhibition, 5-HT 5-HTand 5-HTreceptor antagonism, 5-HTreceptor partial agonism, and 5-HTreceptor agonism, had fewer incidences of sleep-related adverse events reported in depressed patients. In the accompanying paper a polysomnographic electroencephalography (sleep-EEG) study of vortioxetine and paroxetine in healthy subjects indicated that at low/intermediate levels of SERT occupancy, vortioxetine affected rapid eye movement (REM) sleep differently than paroxetine. Here we investigated clinically meaningful doses (80-90% SERT occupancy) of vortioxetine and paroxetine on sleep-EEG in rats to further elucidate the serotoninergic receptor mechanisms mediating this difference. Cortical EEG, electromyography …

How Overqualification Impacts Job Attitudes And Well-Being: The Unique Roles Of Perceptions And Reality, Marijana L. Arvan

USF Tampa Graduate Theses and Dissertations

The recent global economic downturn has stimulated a growing interest among scholars in how employees interpret and respond to the circumstance of being overqualified. However, the overqualification literature has been hindered by uncertainty regarding the extent to which employees’ perceptions of being overqualified are based in reality. The present study sought to address this concern by proposing and testing a theoretical model of objective overqualification, perceived overqualification, job satisfaction, and well-being using a cross-sectional sample of full-time employees who had recently graduated from college. Additionally, the present study investigated cognitive ability, achievement striving, and trait negative affectivity as potential moderators …

Laterality Enhances Numerical Skills In The Guppy, Poecilia Reticulata, Marco Dadda, Christian Agrillo, Angelo Bisazza, Culum Brown

Sentience Collection

It has been hypothesized that cerebral lateralization can significantly enhance cognition and that this was one of the primary selective forces shaping its wide-spread evolution amongst vertebrate taxa. Here, we tested this hypothesis by examining the link between cerebral lateralization and numerical discrimination. Guppies, Poecilia reticulata, were sorted into left, right and non-lateralized groups using a standard mirror test and their numerical discrimination abilities tested in both natural shoal choice and abstract contexts. Our results show that strongly lateralized guppies have enhanced numerical abilities compared to non-lateralized guppies irrespective of context. These data provide further credence to the notion that …

Differential Modification Of Cortical And Thalamic Projections To Cat Primary Auditory Cortex Following Early- And Late-Onset Deafness., Nicole Chabot, Blake E Butler, Stephen G Lomber

Brain and Mind Institute Researchers' Publications

Following sensory deprivation, primary somatosensory and visual cortices undergo crossmodal plasticity, which subserves the remaining modalities. However, controversy remains regarding the neuroplastic potential of primary auditory cortex (A1). To examine this, we identified cortical and thalamic projections to A1 in hearing cats and those with early- and late-onset deafness. Following early deafness, inputs from second auditory cortex (A2) are amplified, whereas the number originating in the dorsal zone (DZ) decreases. In addition, inputs from the dorsal medial geniculate nucleus (dMGN) increase, whereas those from the ventral division (vMGN) are reduced. In late-deaf cats, projections from the anterior auditory field (AAF) …

Suppression Of Locomotor Activity In Female C57bl/6j Mice Treated With Interleukin-1Β: Investigating A Method For The Study Of Fatigue In Laboratory Animals, David R. Bonsall, Hyunji Kim, Awa Ndiaye, Abbey Petronzio, Grace Mckay-Corkum, Penny C. Molyneux, Thomas E. Scammell, Mary E. Harrington

Psychology: Faculty Publications

Fatigue is a disabling symptom in patients with multiple sclerosis and Parkinson’s Disease, and is also common in patients with traumatic brain injury, cancer, and inflammatory disor- ders. Little is known about the neurobiology of fatigue, in part due to the lack of an approach to induce fatigue in laboratory animals. Fatigue is a common response to systemic challenge by pathogens, a response in part mediated through action of the pro-inflammatory cytokine interleukin-1 beta (IL-1β). We investigated the behavioral responses of mice to IL-1β. Female C57Bl/6J mice of 3 ages were administered IL-1β at various doses i.p. Interleukin-1β reduced locomotor …

Distinct Effects Of Contrast And Color On Subjective Rating Of Fearfulness, Zhengang Lu, Bingbing Guo, Anne Boguslavsky, Marcus Cappiello, Weiwei Zhang, Ming Meng

Dartmouth Scholarship

Natural scenes provide important affective cues for observers to avoid danger. From an adaptationist perspective, such cues affect the behavior of the observer and shape the evolution of the observer’s response. It is evolutionarily significant for individuals to extract affective information from the environment as quickly and as efficiently as possible. However, the nearly endless variations in physical appearance of natural scenes present a fundamental challenge for perceiving significant visual information. How image-level properties, such as contrast and color, influence the extraction of affective information leading to subjective emotional perception is unclear. On the one hand, studies have shown that …

Can Non-Haptic Manipulation Of Temperature Influence The Same Emotions As Ostracism?, Rebecca Ann Oglesby

Theses and Dissertations

I explored the possibility that temperature can alter the same variables affected by ostracism (i.e., being ignored and excluded): belonging, control, meaningful existence, and self-esteem need satisfaction, feelings of ostracism, mood, and loneliness. According to the theory of embodied cognition, individuals can associate physical warmth with social intimacy, as well as cold temperatures with social isolation (Zhong & Leonardelli, 2008; IJzerman et al., 2012). Bargh and Shalev (2012) found that participants holding a cold pack reported higher loneliness than participants holding a neutral or warm pack. My study expands upon Bargh and Shalevâ??s (2012) findings by examining more emotions frequently …

Exploring The Dark Side: Investigating The Relationship Between Creativity And Perceptions Of Dishonesty, Kiera Michelle Dymit

Theses and Dissertations

Previous studies have reported a connection between creativity and dishonesty (Beaussart, Andrews, & Kaufman, 2013; Gino & Ariely, 2012; Gino & Wiltermuth, 2014). This study attempts to investigate these finding further, and empirically connect the number of justifications provided or produced for a dishonest behavior to the perceived acceptability of the behavior. 203 participants were given two tasks involving evaluating and justifying dishonest behavior. Those who scored high on the Creative Behavior Inventory were able to produce significantly more justifications overall, but not those who scored high on the Creative Personality Scale. The total number of justifications produced was correlated …

Fear Of Negative Evaluation, Social Anxiety And Response To Positive And Negative Online Social Cues, Chandra L. Bautista, Debra A. Hope

Department of Psychology: Faculty Publications

High social anxiety is associated with negative interpretations of social feedback, maladaptive attributions for success and failure, and excessive attention to internal and external threat cues. In the present study, 40 undergraduate participants with either high or low levels of social anxiety engaged in a series of social interactions with varying types of social feedback: negative, mixed-negative, mixed-positive, and positive. Given the increasing engagement in computer-mediated communication among individuals with high levels of social anxiety, these interactions took place via instant messaging software. Compared to participants with low social anxiety, participants with high social anxiety experienced more self-focused thoughts, negative …

A Neurobiological Pathway That Mediates Stress-Induced Drug Use, Oliver Vranjkovic

Dissertations (1934 -)

Cocaine addiction represents a tremendous health and financial burden on our society and the high rate of relapse to cocaine use in abstinent addicts represents a major barrier to effective therapy. Thus, understanding the factors that contribute to relapse and the underlying neurobiological processes is important for guiding the development of treatment for addiction. Stressful life events often trigger drug use in recovering addicts. The contribution of stress to drug use is problematic due to the unpredictable and often uncontrollable nature of stress. A growing literature indicates that norepinephrine and corticotropin releasing factor (CRF) in the brain play key roles …

Marmosets Treated With Oxytocin Are More Socially Attractive To Their Long-Term Mate, Jon Cavanaugh, Michelle C. Huffman, April M. Harnisch, Jeffrey French

Psychology Faculty Publications

Adult male-female bonds are partly characterized by initiating and maintaining close proximity with a social partner, as well as engaging in high levels of affiliative and sociosexual behavior. Oxytocin (OXT), a neuromodulatory nonapeptide, plays a critical role in the facilitation of social bonding and prosocial behavior toward a social partner (Feldman, 2012). However, less attention has been given to whether augmentation of OXT levels in an individual alters others’ perceptions and behavior toward an OXT-treated social partner. We examined social dynamics in well-established male-female pairs of marmoset monkeys (Callithrix jacchus) in which one member of the pair was …

Welcome Back! Helping Young Children Return To Your Program After Hospitalization, Nanci Weinberger

Applied Psychology Department Faculty Journal Articles

Every week I’m lucky enough to spend a couple of hours reading to hospitalized children. Sometimes I also get to be with other formerly hospitalized children as a camp volunteer. In spite of their incredibly varied experiences, one thing stands out: kids will be kids! This can mean many things, but to me as a volunteer—who just happens to be a developmental psychologist—it means that young children want to feel safe, want to explore their world, and want to have fun.

The Effect Of Retention Interval On Temporal Control Of Responding In Rats On The Peak Interval Procedure, Catherine Tsiris

Dissertations, Theses, and Capstone Projects

A considerable body of literature on time perception has investigated the effects of short intratrial retention intervals (RI) in the seconds range, on temporal performance, however there is a dearth of research examining the effects of long, intersession RIs (hours to days range) on timing. The present study examined the effect of two different RI durations (2 days and 70 days) on time estimates in subjects on the peak interval procedure. Twenty-four rats, eight per group, were exposed to one of three conditions. The experimental group was trained at 5 months and tested after a 70-day RI. One control group …

Deception As Forgery: The Role Of Reference Information In Honesty And Deceit, Timothy John Luke

Dissertations, Theses, and Capstone Projects

Using concepts derived from cybernetics, self-presentation theory, and research on human self-regulation, I develop a cybernetic perspective of deception and self-presentation. In this perspective, human communication, both honest and deceptive, is controlled by feedback mechanisms. I report two studies designed to test the basic prediction derived from the cybernetic framework that deceivers are able to better emulate truth-tellers when they have access to relevant reference information about the way truth-tellers behave. Each study manipulated liars' and truth-tellers' access to reference information in a different manner. In Study 1, some participants viewed video recordings of people being interviewed in a manner …

The Role Of Dependence In Alcohol Reinforcement: Neurobehavioral Mechanisms, Michal Atzram

Dissertations, Theses, and Capstone Projects

The motivation to consume alcohol is complex, though physiological dependence has long been implicated in alcohol reinforcement and alcoholism. The research presented here was conducted to examine the role of alcohol dependence on voluntary alcohol consumption and preference, the validity of the Lieber-DeCarli (LD) liquid diet as a procedure to induce dependence, and the effect of alcohol administration on dopamine and endocannabinoids. While the LD diet has been used extensively to induce alcohol toxicity and teratogenic effects, there has not been research that has examined its use in the development of dependence and alcohol reinforcement. This research utilized varying periods …

Three Potential Mediators Of The Effects Of Child Abuse And Neglect On Smoking In Middle Adulthood, Miriam Ghirmay

Dissertations, Theses, and Capstone Projects

The purpose of the current study was fourfold: (1) to determine whether individuals with histories of child abuse and neglect have higher rates of current cigarette smoking in middle adulthood compared with matched controls; (2) to examine whether individuals with histories of abuse and/or neglect are at increased risk for higher rates of current psychopathology (anxiety or depression), negative coping, and past year traumas and victimization experiences in adulthood compared with matched controls; (3) to determine whether current psychopathology, negative coping, and past year traumas and victimization experiences mediate the relationship between child maltreatment and current smoking; and (4) to …

The Role Of The Vta Nmda Receptors, Vta Da Cells And Vta Terminal Regions In Reward-Related Learning, Karen Kest

Dissertations, Theses, and Capstone Projects

Reward-related learning occurs when an initially neutral stimulus acquires the capacity to elicit responses similar to an unconditioned stimulus (US) with which it is associated, in which case the stimulus now functions as a conditioned stimulus (CS). The mechanisms whereby stimuli come to function as CSs are not fully understood and comprise the theme of this dissertation. We have previously proposed that coincident signals from an unconditioned and the eventual conditioned stimulus (US and CS) signals on dopamine (DA) cells of the ventral tegmental area (VTA) leads to strengthening of CS synapses, allowing the CS to acquire the ability to …

Developmental Coordination Disorder: The Relationship Between Gait And Attention With Possible Implications For Early Identification And Intervention, Yocheved Bensinger-Brody

Dissertations, Theses, and Capstone Projects

The aim of this research was to evaluate how increased levels of challenge to attentional capacity would affect the motor planning and coordination in the gait of children at risk of Developmental Coordination Disorder (DCD) across developmental ages. The study incorporated a dual task paradigm requiring both motor and attention performance, with the primary hypothesis that children who are at risk of DCD across different ages (3- to 8 yrs.-of-age) would demonstrate an alteration in their motor strategies if they were simultaneously engaging in an attention task. A secondary hypothesis of this study was that there is an underlying deficit …

The Relationship Between A Norm Referenced Measure Of Theory Of Mind And Preschoolers' Social Skills In The Classroom, Sarah Ellen Birch

Dissertations, Theses, and Capstone Projects

This study sought to examine the effect of Theory of Mind (ToM) performance as measured by a norm-referenced assessment on the social skills of a multicultural group of preschool students. This study extends the current research in this area. Most previous studies examined the relationship among ToM, other social cognitive skills and social skills using participants from predominately Caucasian middle class families (Slaughter et al., 2015). Additionally, earlier research relied primarily on homemade measures of such skills (Cassidy et al., 2003; Disendruck & Ben-Eliyahu, 2006; McAlister & Peterson, 2013; Watson et al., 1999; Walker, 2005).

Participants included 67 children between …

Wh-Question Processing In Children With Cochlear Implants, Zarabeth Waldman Deluca

Dissertations, Theses, and Capstone Projects

Children with cochlear implants (CIs) have exhibited difficulty accurately answering and producing wh-questions. The syntactic construction of wh-questions include syntactic movement, whereby the wh-question phrase that replaces the subject or object noun is fronted to the beginning of the sentence. This leaves a syntactic gap at the subject or object's original location, to be filled by the listener during immediate language processing. One view is that this syntactic gap is resolved by retaining that filler concept in working memory (WM), until it can be reintegrated into the wh-question. However, the CI population is also notable for WM deficits, which may …

Art As Communication: Employing Gricean Principles Of Communication As A Model For Art Appreciation, Melissa June Dolese

Dissertations, Theses, and Capstone Projects

Abstract

How and why artworks elicit varied preferences and judgments among different individuals remains a topic with many unresolved issues. For instance, individuals with little artistic experience tend to show little appreciation for abstract art, even though such works often show a highly skilled organization of visual elements. A key aspect of a positive aesthetic experience concerns the ability of viewers to construct meaning. I propose that viewers attempt to make meaning of artworks due to a sense that art is a communicative process. Here I attempt an application of one intentionalist model of communication, the Gricean framework, to visual …

Variability, Stability, And Flexibility In The Speech Kinematics And Acoustics Of Adults Who Do And Do Not Stutter, Eric S. Jackson

Dissertations, Theses, and Capstone Projects

It is well known that people who do and do not stutter produce speech differently, at least some of the time, even when perceived as fluent. One way that investigators have assessed these differences is by measuring variability, or the inconsistency of repeated speech movements. Variability in speech has typically been quantified using linear analysis techniques (e.g., measures of central tendency), and results have indicated that people who stutter produce speech that is (sometimes) characterized by increased variability. However, variability is a complex phenomenon, one that cannot be assessed by linear methods alone. This dissertation employs linear and nonlinear analysis …

Sex-Dependent Role Of Interleukin-1 Signaling In Emotional And Cognitive Behaviors In Mice: Phenotyping Male And Female Il1-R1 Null Mutant Mice, Jennifer Anne Johnson

Dissertations, Theses, and Capstone Projects

IL1-R1 null mutant mice (IL1-R1 KO) have reduced signaling in the interleukin-1 (IL-1) pathway, making them a convenient model for testing the importance of IL-1 in either the development or maintenance of mouse behaviors. Prior research has revealed impaired cognitive and emotional processes in adult male IL1-R1 KO mice, including impaired spatial learning and memory and decreased anxiety with associated impairments in hippocampal cell proliferation and signal transmission. The current studies explored the neuroanatomy and behavioral phenotype of both male and female IL1-R1 KO mice. An array of behavioral tests was administered, including retesting at an older age for cognitive …

Whistles Of Sympatric Species Of Bottlenose Dolphins (Tursiops Truncatus) And Spotted Dolphins (Stenella Frontalis) In The Bahamas: Acoustic Characteristics And Contextual Use, Jennifer Daisy Kaplan

Dissertations, Theses, and Capstone Projects

Bottlenose and spotted dolphins in the Bahamas frequently interact in social, socio-sexual, and aggressive encounters, and whistles are thought to play a key role in their communication. Concurrent vocal and behavioral recordings of wild sympatric species of Atlantic spotted dolphins (Stenella frontalis) and Atlantic bottlenose dolphins (Tursiops truncatus) were collected from three Bahamas populations, and the acoustic parameters, structure, and contextual use of their whistles were analyzed. The mean acoustic parameters of spotted dolphins in the Bimini and White Sand Ridge Bahamas populations were higher in frequency than those of bottlenose dolphins, but bottlenose dolphins produced whistles that had higher …

Interleukin-1 (Il-1) As A Potential Contributor To The Pathophysiology Of Alzheimer's Disease, Sara Nicole Resch

Dissertations, Theses, and Capstone Projects

Elevations of the pro-inflammatory cytokine interleukin-1 (IL-1) have been reported as part of the inflammatory response to injury and neurodegenerative disorders. The observation of increased IL-1 levels in the brains of patients with Alzheimer's disease (AD) triggered over two decades of research implicating IL-1 in the disease pathogenesis. IL-1 has been suggested to modulate a variety of actions related to AD pathology, including the processing of the Aβ precursor protein and deposition of amyloid plaques. IL-1 also activates glial cells and induces recruitment of leukocytes and peripheral macrophages to the CNS across the blood-brain barrier (BBB). When exposed to IL-1, …

Senescent Changes In Orientation, Frequency, And 3-D Slant And Shape Perception, Danny Tam

Dissertations, Theses, and Capstone Projects

The ability to perceive the 3-Dimensional world is effortless despite the fact that the input to the visual system is 2-Dimensional. Attempts to derive biologically plausible models of shape from texture have focused on how changes in orientation and spatial frequency information are processed based on the response properties of primary visual cortex (V1) neurons. However, the relative contributions of orientation and spatial frequency information in detecting slant and shape from 3-D surfaces are not well understood. Additionally, in senescence, changes in optical components of the eye result in reduced frequency sensitivity, but whether concurrent neurophysiological changes affect the ability …
