The Use Of Judgement Bias To Assess Welfare In Farm Livestock, L. Baciadonna, A. G. Mcelligott

Sentience Collection

The development of accurate measures of animal emotions is important for improving and promoting animal welfare. Cognitive bias indicates the effect of emotional states on cognitive processes, such as memory, attention, and judgement. Cognitive bias tests complement existing behavioural and physiological measures for assessing the valence of animal emotions indirectly. The judgement bias test has been used to assess emotional states in non-human animals; mainly in laboratory settings. The aim of this review is to summarise the findings on the use of the judgement bias test approach in assessing emotions in non-human animals, focusing in particular on farm livestock. The …

Intrasexual Selection Drives Sensitivity To Pitch, Formants And Duration In The Competitive Calls Of Fallow Bucks, Benjamin J. Pitcher, Elodie Briefer, Alan G. Mcelligott

Ethology Collection

Background: Mammal vocal parameters such as fundamental frequency (or pitch; fo) and formant dispersion often provide information about quality traits of the producer (e.g. dominance and body size), suggesting that they are sexually selected. However, little experimental evidence exists demonstrating the importance of these cues in intrasexual competition, particularly fo. Male Fallow deer (bucks) produce an extremely low pitched groan. Bucks have a descended larynx and generate fo well below what is expected for animals of their size. Groan parameters are linked to caller dominance, body size and condition, suggesting that groans are the product of sexual selection. Using a …

Predator Recognition And Responses In The Endangered Macquarie Perch (Macquaria Australasica), Culum Brown, Jennifer Morgan

Sentience Collection

Macquarie perch, Macquaria austalasica, is an endangered species endemic to southern Australia whose distribution is highly fragmented and continues to decline. Key threatening processes include habitat destruction, dams and weirs, overfishing and interactions with introduced species. Here, we examined the responses of small and large Macquarie perch to two native predators and to the introduced redfin perch, Perca fluviatilis. Our results showed that Macquarie perch generally avoided large-bodied native predators but was attracted to small-bodied native predators. Responses to large and small redfin perch lay between these two extremes, suggesting that the Macquarie perch does treat these foreign fish as …

“Goats That Stare At Men” – Dwarf Goats Alter Their Behaviour In Response To Human Head Orientation But Do Not Spontaneously Use Head Direction As A Cue In A Food-Related Context, Christian Nawroth, Eberhard Von Borell, Jan Langbein

Social Cognition Collection

Recently, comparative research on the mechanisms and species-specific adaptive values of attributing attentive states and using communicative cues has gained increased interest, particularly in non-human primates, birds, and dogs. Here, we investigate these phenomena in a farm animal species, the dwarf goat (Capra aegagrus hircus). In the first experiment, we investigated the effects of different human head and body orientations, as well as human experimenter presence/absence, of a human on the behaviour of goats in a food-anticipating paradigm. Over a 30-sec interval, the experimenter engaged in one of four different postures or behaviours (head and body towards the subject, head …

Scent Of The Familiar: An Fmri Study Of Canine Brain Responses To Familiar And Unfamiliar Human And Dog Odors, Gregory S. Berns, Andrew M. Brooks, Mark Spivak

Social Cognition Collection

Understanding dogs’ perceptual experience of both conspecifics and humans is important to understand how dogs evolved and the nature of their relationships with humans and other dogs. Olfaction is believed to be dogs’ most powerful and perhaps important sense and an obvious place to begin for the study of social cognition of conspecifics and humans. We used fMRI in a cohort of dogs (N = 12) that had been trained to remain motionless while unsedated and unrestrained in the MRI. By presenting scents from humans and conspecifics, we aimed to identify the dimensions of dogs’ responses to salient biological …

Anger Is A Gift: How Psychology And Ethics Illuminate Moral Responsibility - Peter White Scholar Grant, Zac Cogley

Grants

This proposal details a project that builds on my current interdisciplinary research program to articulate and develop a novel theory of moral responsibility. Like many philosophers, I maintain that whether someone is morally responsible for an action depends on whether it is appropriate to adopt attitudes such as anger and resentment toward the person. What makes my view unique is how I understand these “reactive attitudes.” I show they serve three functions: to appraise the action of a person (e.g. that it is wrong), to communicate the appraisal of wrongdoing to others, and to sanction the perceived wrongdoer. My defense …

Examining The Relationship Among Genes, Attention Bias To Emotion, Depression In Youth, Jessica L. Jenness

Electronic Theses and Dissertations

The investigation of biologically initiated pathways to psychological disorder is critical to advance our understanding of mental illness. Research has suggested that attention bias to emotion may be an intermediate trait for depression associated with biologically plausible candidate genes, such as the serotonin transporter (5-HTTLPR) and catechol-o-methyl-transferase (COMT) genes, yet there have been mixed findings in regards to the precise direction of effects. The experience of recent stressful life events (SLEs) may be an important, yet currently unstudied, moderator of the relationship between genes and attention bias as SLEs have been associated with both gene expression and attention to emotion. …

Nicotine Receptors Mediating Sensorimotor Gating And Its Enhancement By Systemic Nicotine., Farena Pinnock, Daniel Bosch, Tyler Brown, Nadine Simons, John R Yeomans, Cleusa Deoliveira, Susanne Schmid

Brain and Mind Institute Researchers' Publications

Prepulse inhibition (PPI) of startle occurs when intensity stimuli precede stronger startle-inducing stimuli by 10-1000 ms. PPI deficits are found in individuals with schizophrenia and other psychiatric disorders, and they correlate with other cognitive impairments. Animal research and clinical studies have demonstrated that both PPI and cognitive function can be enhanced by nicotine. PPI has been shown to be mediated, at least in part, by mesopontine cholinergic neurons that project to pontine startle neurons and activate muscarinic and potentially nicotine receptors (nAChRs). The subtypes and anatomical location of nAChRs involved in mediating and modulating PPI remain unresolved. We tested the …

Prolonged In Vivo Retention Of A Cathepsin D Targeted Optical Contrast Agent In A Mouse Model Of Alzheimer's Disease., Jonatan A Snir, Mojmir Suchy, Keith St Lawrence, Robert H E Hudson, Stephen H Pasternak, Robert Bartha

Brain and Mind Institute Researchers' Publications

BACKGROUND: Cathepsin D (CatD) is a lysosomal protease that is elevated early in Alzheimer's disease (AD). We have previously developed a Targeted contrast agent (CA) to detect CatD activity in vivo, consisting of a magnetic resonance imaging/fluorescent moiety linked to a cell penetrating peptide (CPP) by means of a CatD cleavage site and have demonstrated its uptake in the brain of an AD mouse model.

OBJECTIVE: The purpose of this study was to characterize the in vivo retention of a near infra-red fluorescent dye labeled version of this CA.

METHODS: Six adult C57Bl/6 wild-type mice and six adult 5XFAD transgenic …

High-Field Functional Imaging Of Pitch Processing In Auditory Cortex Of The Cat., Blake E. Butler, Amee J Hall, Stephen G Lomber

Brain and Mind Institute Researchers' Publications

The perception of pitch is a widely studied and hotly debated topic in human hearing. Many of these studies combine functional imaging techniques with stimuli designed to disambiguate the percept of pitch from frequency information present in the stimulus. While useful in identifying potential "pitch centres" in cortex, the existence of truly pitch-responsive neurons requires single neuron-level measures that can only be undertaken in animal models. While a number of animals have been shown to be sensitive to pitch, few studies have addressed the location of cortical generators of pitch percepts in non-human models. The current study uses high-field functional …

The Truth About Humans: The Decision To Adopt Dogs & Cats, Leann Stadtlander

2010-2016 Archived Posters

Millions of dogs and cats are adopted from animal shelters every year, however, little is known about why specific animals are adopted. This study examines the qualitative comments given by adopters of cats and dogs for selecting specific animals. Differences between the species and insights into human/animal interactions are discussed.

Gerontological Intelligence Test, Erika Beatriz Gobbi

ETD Archive

The current study was designed as a preliminary analysis to design an alternative intelligence scale for older adults ages 65 plus. This study was predominantly administered to White participants with a females being the prominent gender (30 females, 14 males). 44 participants were administered the four subtests Analogies, Matrices, Geometric Shapes and Information. The Block Design and Vocabulary from the Wechsler Adult Intelligence Scale was administered to assess the validity of the current study. By creating a more tailored intelligence test for older adults, problems such as fatigue, administrator bias and physical limitations can be addressed. With the population of …

Tweeting About Sexism: The Well-Being Benefits Of A Social Media Collective Action., Mindi D. Foster

Psychology Faculty Publications

Although collective action has psychological benefits in non-gendered contexts (e.g., Drury et al., 2005), the benefits for women taking action against gender discrimination are unclear. This study examined how a popular, yet unexplored potential form of collective action, namely tweeting about sexism, affects women’s well-being. Women read about sexism and were randomly assigned to tweet, or to one of three control groups. Content analyses showed tweets exhibited collective intent and action. Analyses of linguistic markers suggested public tweeters used more cognitive complexity in their language than private tweeters. Profile analyses showed that compared to controls, only public tweeters showed decreasing …

Orbitofrontal 18f-Dopa Uptake And Movement Preparation In Parkinson’S Disease, Lucio Marinelli, Arnoldo Piccardo, Laura Mori, Silvia Morbelli, Nicola Girtler, Antonio Castaldi, Agnese Picco, Carlo Trompetto, Maria Felice Ghilardi, Giovanni Abbruzzese, Flavio Nobili

Publications and Research

In Parkinson’s disease (PD) degeneration of mesocortical dopaminergic projections may determine cognitive and behavioral symptoms. Choice reaction time task is related to attention, working memory, and goal-directed behavior. Such paradigm involves frontal cortical circuits receiving mesocortical dopamine which are affected early in PD. The aim of this study is to characterize the role of dopamine on the cognitive processes that precede movement in a reaction time paradigm in PD.We enrolled 16 newly diagnosed and untreated patientswith PDwithout cognitive impairment or depression and 10 control subjectswith essential tremor. They performed multiple-choice reaction time task with the right upper limb and brain …

The Potential Impact Of Rape Culture On Juror Decision Making: Implications For Wrongful Acquittals In Sexual Assault Trials., Meagen M. Hildebrand, Cynthia J. Najdowski

Psychology Faculty Scholarship

Feminist writers contend that Americans live in a culture that supports sexualized aggression and violence against women. This “rape culture” is reflected in our society by the pervasive endorsement of rape myths and sexual objectification of women, both of which are legitimized by everyday media. One potential consequence of living in a rape culture is that individuals may themselves come to endorse rape myths and sexually objectify women, and, in turn, perceive certain forms of sexual violence against women as defensible. This is concerning considering the significant role that laypeople play in administering justice in sexual assault cases, but research …

Critical Period Conditioning By Orgasm During Heterosexual Oral Sex, Kristy N. Woods

Theses, Dissertations and Capstones

Data were obtained retrospectively and anonymously using a computerized survey instrument from 450 female and 489 male participants who had experienced orgasm during oral sex before age 18, as well as 352 female and 151 male participants who had not experienced an orgasm while receiving oral sex before age 18. Female participants who experienced an orgasm during oral sex prior to age 18 were significantly more likely to experience an orgasm during oral sex after age 18. For male participants, although the difference was in the hypothesized direction, it did not reach significance. Female participants who experienced an orgasm during …

Personality Traits In Parkinson's Disease, Lindsey Clark

Undergraduate Review

Parkinson’s disease (PD) has been associated with certain personality characteristics, including low novelty seeking and high harm avoidance, but examination of the literature reveals mixed results. One limitation of studies to date is their failure to examine gender differences or to even include both male and female participants in their studies. The aim of the present study was to examine gender differences in personality traits among individuals with and without PD. Twenty-three non-demented PD patients (12F/11M) and 21 age and education matched normal control adults (NC; 11F/10M) were administered the Temperament and Character Inventory (TCI), a 240-item self-report questionnaire assessing …

Behavior-Associated And Post-Consumption Glucose Entry Into The Nucleus Accumbens Extracellular Space During Glucose Free-Drinking In Trained Rats, Ken T. Wakabayashi, Eugene A. Kiyatkin

Department of Psychology: Faculty Publications

Glucose is the primary energetic substrate for the metabolic activity of brain cells and its proper delivery from the arterial blood is essential for neural activity and normal brain functions. Glucose is also a unique natural reinforcer, supporting glucose-drinking behavior without food or water deprivation. While it is known that glucose enters brain tissue via gradient-dependent facilitated diffusion, it remains unclear how glucose levels are changed during natural behavior and whether the direct central action of ingested glucose can be involved in regulating glucose-drinking behavior. Here, we used glucose biosensors with high-speed amperometry to examine the pattern of phasic and …

Visual Landmark Information Gains Control Of The Head Direction Signal At The Lateral Mammillary Nuclei, Ryan M. Yoder, J.R. Peck, J.S. Taube

Psychology

The neural representation of directional heading is conveyed by head direction (HD) cells located in an ascending circuit that includes projections from the lateral mammillary nuclei (LMN) to the anterodorsal thalamus (ADN) to the postsubiculum (PoS). The PoS provides return projections to LMN and ADN and is responsible for the landmark control of HD cells in ADN. However, the functional role of the PoS projection to LMN has not been tested. The present study recorded HD cells from LMN after bilateral PoS lesions to determine whether the PoS provides landmark control toLMNHDcells. After the lesion and implantation of electrodes,HDcell activity …

Closer Than You Think: The Influence Of Border Bias On Perceptions Of Mapped Hazards, Sarah D. Gardiner

Undergraduate Review

In a replication and extension of “border bias” research conducted by Mishra and Mishra (2010) and Molloy and colleagues (2012; 2013), who found that mapped threats within state borders were judged to be a greater risk than equidistant out of state threats, the effects of color (added to indicate zones of potential exposure) and a “double border” (on maps and in the lab) were measured. Support was found for border bias in that state boundaries appeared to influence risk perception. As hypothesized, there was also a significant effect for color boundaries, and participants avoided a location shown at an equidistant …

A Humanistic Approach To Understanding Child Consumer Socialization In Us Homes, Lucy Atkinson, Michelle R. Nelson, Mark A. Rademacher

Scholarship and Professional Work - Communication

We present findings from a qualitative, multisite, multi-method, longitudinal study of parents and their preschool-aged children that explores the intersections of marketing influences in the home and in the larger outside world of children. Findings indicate that preschoolers represent complicated and nuanced “consumers in training” beyond predictions based on their “perceptual stage of development.” Specifically, our data revealed interesting ways in which marketing and consumer culture can foster a number of pro-social consumer outcomes (e.g., charity, gift-giving, financial literacy). We also noted an emerging understanding by preschoolers of the social meanings of goods for identity construction and product evaluation. Finally, …

An Investigation Of Compromise Across Political Parties, Jarryd T. Willis

Psychology Dissertations - Archive

The debt ceiling crisis of 2011, the government shutdown of 2013, and the extension of partisanship past the water's edge into Ukrainian-Russian and Israeli-Iranian politics are all recent examples of how polarized American politics has become. Despite the growing desire and necessity for more compromise in American politics, "the systematic study of compromise remains surprisingly under-developed" (Bellamy, Kornprobst, & Reh, 2012). The purpose of this dissertation was to test the premise that citizens create congress, and therefore citizens who value compromise could incentivize more integrative negotiations than citizens who only want their representative to adhere to their values. Using the …

An Examination Of The Psychometric Properties Of The Working Model Of The Child Interview Coding Scheme With Biological Mothers Who Have Maltreated, Brian D. Gustman

Theses and Dissertations--Educational, School, and Counseling Psychology

There are hundreds of thousands of children living in foster care in the United States on any given day. Mental health professionals may be called upon to assist with evaluating the parental capacity of these children’s parents in order to inform reunification decisions. One of the key parental capacity domains to be evaluated is the relationship between parent and child (Schmidt et al., 2007). The Working Model of the Child Interview coding scheme (WMCI; Zeanah et al., 1996) is one tool for evaluating this relationship. There is a significant practice-to-research gap with this measure. To date, no peer-reviewed studies have …

Altrusim, Fact Or Fiction?: An Exploration Of Altruism And Egoism In The Context Of Religion And Service Learning, Sarah Pawlicki

A with Honors Projects

This research paper questions the existence of true altruism, by discussing social psychological, philosophical, and theological theories regarding altruism and egoism. The author then discusses her findings in the context of two service learning projects which involved volunteering at the Champaign County Humane Society and Salt and Light, A Christian ministry that provides job counseling, computer access, a thrift and food store. She concludes that, rather than questioning the existence of true altruism exists, the focus should be on doing good for others, regardless of motives.

Can Mutual Trust Explain The Diversity-Performance Relationship? A Meta-Analysis, Pereira Jennifer Feitosa

Electronic Theses and Dissertations

Trust is gaining attention for its benefits to both teams and organizations as a whole (Fulmer & Gelfand, 2012). The difficulty of building it in comparison to the ease of destroying it calls for a deeper understanding of trust, as well as its relationship with critical team outcomes (Colquitt, LePine, Piccolo, Zapata, & Rich, 2012). Unfortunately, current research has progressed in a disjointed manner that requires the integration of findings before a more parsimonious and descriptive understanding of trust at the team-level can be developed. Beyond this basic understanding, research is needed to explore the nature of trust in teams …

The Role Of The Lateral Habenula In The Affective Dimension Of Pain, Michelle Marie White

Psychology Theses - Archive

The lateral habenula (LHb) functions as a hub that integrates information from cortical regions to aid in emotional decision-making, as well as helping to create response strategies under stress (Hikosaka, 2010; Proulx, Hikosaka, & Malinow, 2014; Thorton, Bradbury, & Davies, 1990; Evans & Thorton, 1984; Thorton & Evans, 1984; Thorton & Evans, 1982; Thorton, Evans, & Harris, 1985). In addition, the LHb functions in a descending pain modulatory circuit involving both the nucleus accumbens and periacqueductal gray (Shelton, Becerra, & Borsook, 2012). These two functions of the LHb indicate its importance in decision-making during heightened states of arousal, such as …

Building An Adaptive Brain Across Development: Targets For Neurorehabilitation Must Begin In Infancy, Jamie O. Edgin, Caron A. C. Clark, Esha Massand, Annette Karmiloff-Smith

Department of Educational Psychology: Faculty Publications

Much progress has been made toward behavioral and pharmacological intervention in intellectual disability, which was once thought too difficult to treat. Down syndrome (DS) research has shown rapid advances, and clinical trials are currently underway, with more on the horizon. Here, we review the literature on the emergent profile of cognitive development in DS, emphasizing that treatment approaches must consider how some “end state” impairments, such as language deficits, may develop from early alterations in neural systems beginning in infancy. Specifically, we highlight evidence suggesting that there are pre- and early postnatal alterations in brain structure and function in DS, …

Examining The Neuroprotective Properties Of 3-Dimethoxybenzylidene-Anabasine (Dmxb-A) In A Third Trimester Chronic Ethanol Exposure Model In Rats, Logan J. Fields

Theses and Dissertations--Psychology

Excitotoxicity caused by ethanol (ETOH) withdrawal (EWD) is highly detrimental to the developing brain. Targeting this excitotoxicity has been shown to be a promising approach for improving outcome following developmental ETOH exposure. Activation of nicotinic acetylcholine receptors (nAChR), in the central nervous system can be protective against EWD. We examined the ability of DMXB-A, a α₇ nAChR agonist, to reduce neurotoxicity caused by EWD in the hippocampus. To test this, an organotypic hippocampal slice culture was used. Slices were exposed to ETOH (100mM) or control medium. After 10 days, the slices were treated with DMXB-A (1, 3, or 10uM) …

The Effects Of Viewing Patient-Related Physiological Data On Students' Mental Health Stigma, Sabrina Kohls

Undergraduate Honors Thesis Projects

Abstract

Figuring out how to reduce the negative stigma of mental illness could prove useful to patients and mental health professionals. Previous research has suggested that emphasizing the biological and physiological components of mental disorders may affect how people with these disorders are perceived. Biogenetic explanations have been shown to lessen stigma towards mentally ill patients in some respects. The present study compared participants’ evaluations of a hypothetical depressed person whose description was accompanied by either an MRI of the patient’s brain or a picture of the patient’s sad face. Analyses compared participants’ responses on three aspects of stigma: social …
