Reber’S Caterpillar Offers No Help, Carl Safina

Animal Sentience

Reber’s target article “Caterpillars, consciousness and the origins of mind” seems only to shift but not to address the question of where the mind is and how minds occur.

The Nmda Receptor Glun2c Subunit Controls Cortical Excitatoryinhibitory Balance, Neuronal Oscillations And Cognitive Function, Subhash C. Gupta, Aparna Ravikrishnan, Jinxu Liu, Zhihao Mao, Ratnamala Pavuluri, Brandon G. Hillman, Pauravi J. Gandhi, Dustin J. Stairs, Ming Li, Rajesh R. Ugale, Daniel T. Monaghan, Shashank M. Dravid

Department of Psychology: Faculty Publications

Despite strong evidence for NMDA receptor (NMDAR) hypofunction as an underlying factor for cognitive disorders, the precise roles of various NMDAR subtypes remains unknown. The GluN2Ccontaining NMDARs exhibit unique biophysical properties and expression pattern, and lower expression of GluN2C subunit has been reported in postmortem brains from schizophrenia patients. We found that loss of GluN2C subunit leads to a shift in cortical excitatory-inhibitory balance towards greater inhibition. Specifically, pyramidal neurons in the medial prefrontal cortex (mPFC) of GluN2C knockout mice have reduced mEPSC frequency and dendritic spine density and a contrasting higher frequency of mIPSCs. In addition a greater number …

Combat Psychology: Learning To Kill In The U.S. Military, 1947-2012, Patrick Mckinnie

Graduate Theses

In his 1947 work Men Against Fire: The Problem of Battle Command, historian S. L. A. Marshall convinced the U.S. government and military of the critical need for improved techniques in combat psychology. However, his more fundamental assertion that soldiers needed to be trained to overcome an innate psychological resistance to killing would prompt some in the military as well as scholars and medical experts to examine the heart and mind of the soldier in combat. As a result, an emergent science called killology became a critical component in the U.S. military’s quest to better train soldiers for the …

Architecture Undergraduate Honors Theses

This paper attempts to provide a theoretical framework for making ecosystem function and ecologically sustainable design more perceptible or sensible to people through architecture and the built environment. Design features of the Bertschi School Science Wing and the Bullitt Center in Seattle, Washington are incorporated to illustrate the sensory legibility of ecological sustainability criteria.The criteria are available to designers to help educate a building's occupants on environmentally sustainable design and motivate more sustainable behavior.

Investigating Intra-Island Translocation As A Conservation Strategy For The Turks And Caicos Iguana: The Impact Of Homing And Stress, Tarren Kay Wagener

Psychology Dissertations - Archive

The Turks and Caicos iguana, Cyclura carinata, is listed as critically endangered by the International Union for the Conservation of Nature due to introduced mammals and habitat alteration from human development. Inter-island translocations are a key conservation strategy for the species and, while resource intensive, have been successful to date. However suitable islands for translocation (good habitat and free of mammals) are scarce despite a surplus of animals threatened by human development. Intra-island translocation strategies that complement human needs must be found. Big Ambergris Cay (supporting the single largest remaining population of TCI iguanas) presents a unique opportunity to determine …

Dopamine D1 Receptor Activity In The Basolateral Amygdala Is Important For Mediating Fear, Reward And Safety Discrimination Learning, Ka Ho Ng

Open Access Theses

Post traumatic stress disorder (PTSD) patients frequently show impairment in safety learning (Jovanovic, Kazama, Bachevalier, & Davis, 2012). Since the amygdala is known to be critical for emotional processing(Wassum & Izquierdo, 2015) and dopamine signaling in the amygdala is important for mediating both fear and reward learning, current experiments examined the role of dopamine signaling in the BLA in mediating both safety learning and reward seeking. We manipulated dopamine D1 receptor activity with a D1 receptor agonist (SKF 38393) or D1 receptor antagonist (SCH23390) either systemically or infused directly into the BLA 20 minutes prior to training rats in a …

Task Manipulation Effects On The Relationship Between Working Memory Capacity And Go/No-Go Performance, Elizabeth A. Wiemers

Open Access Theses

Seemingly minor task manipulations can have large and sometimes unpredicted effects on task performance. Despite this, single tasks are typical in both research and assessment applications. This series of experiments aims to systematically investigate the differences between various perceptual and semantic versions of go/no-go tasks and their relationships with working memory capacity (WMC) with the goal of determining the cause of inconsistencies in the literature. Because these versions of the go/no-go have not previously been systematically studied, the first experiment does so. After determining which performance differences exist based on versions of both task and decision, and noting that these …

Teoria De La Mente Y Sociedad En La Narrativa Policiaca De Lorenzo Silva Y Francisco Garcia Pavon: Estereotipos, Roles De Genero Y Minorias, Jesus Castro Gorfti

Open Access Dissertations

Spanish:

The purpose of this study is to utilize certain aspects of cognitive psychology as a framework to analyze the police procedural novels of two Spanish authors: Francisco García Pavón and Lorenzo Silva. Specifically, we will focus on two main aspects of the mind studied by the cognitive sciences: Theory of Mind and metarepresentations. Theory of Mind (ToM) refers to the capacity that human beings have to attribute mental states to other humans, as well as oneself, based on their bodily and facial gestures. The concept of metarepresentation refers to the ability of humans to keep track of who said …

How Training Set And Prior Knowledge Affect Preschoolers' Perception Of Quantity And Early Number Learning, Arum Han

Open Access Dissertations

This dissertation examines how training on the iPad can improve children’s quantity recognition, and whether different types of training might be warranted for children with different levels of experience. Study 1 tested the effects of multiple exemplar training (3 cars / 3 apples / 3 ducks, etc.) versus single exemplar training (3 cars / 3 cars / 3 cars, etc.) in recognizing quantities. For children just learning to recognize quantities (0-2 knowers), training with multiple exemplars was most effective for quantities three and four. For 3-6 knower children, single exemplar training was most effective for learning quantities five and six. …

Asymmetry Of Gains And Losses: Behavioral And Electrophysiological Measures, Diego Gonzalo Flores

Theses and Dissertations

The purpose of this research was to explore the effects of small monetary or economic gains and/or losses on choice behavior through the use of a computerized game and to determine gain/loss ratio differences using both behavioral and electrophysiological measures. Participants (N=53) played the game in several 36 minute sessions. These sessions operated with concurrent variable-interval schedules for both rewards and penalties. Previously, asymmetrical effects of gains and losses have been identified through cognitive studies, primarily due to the work of nobel laureates Daniel Kahneman and Amos Tversky (1979). They found that the effect of a loss is twice (i.e., …

Habitat Use By Bottlenose Dolphins, Tursiops Truncatus, In Roanoke Sound, North Carolina, Shauna Marisa Mcbride

Dissertations

Information on the habitat use of a species is important to develop conservation efforts and management strategies for that species. Roanoke Sound, North Carolina is primarily a seasonal habitat for bottlenose dolphins, Tursiops truncatus, from late spring to early fall, but little information is known about how dolphins use this area. Transect survey data and opportunistic survey data collected by the Outer Banks Center for Dolphin Research from 2009 to 2015 were used to analyze dolphin habitat use. The objectives of this project were to: 1) identify areas that were important to dolphins, 2) determine which behaviors were observed …

The Relationship Between P300 Evoked Potentials And Prefrontal Cortex Oxygen Use: A Combined Eeg And Nirs Study, Will S. Rizer

All NMU Master's Theses

The P300 subcomponent, P3b, is an event related potential detected at the scalp surface when a working memory comparison results in differences between the contents of working memory and incoming stimulus information. Previous research has indicated that as infrequent targets become more difficult to detect (morphologically similar to a frequent non-target stimulus) the P300 becomes attenuated. fMRI research has also indicated increased prefrontal cortex (PFC) activity during P300 generation. To examine the relationship between P3b amplitude and PFC activity participants performed an easy and difficult target detection task in both EEG and NIRS called the oddball. The EEG and behavioral …

The Effects Of Punishment On Resistance To Change And Reinstatement, Tomesha A. Manora

Dissertations

Resistance to change (RTC) refers to the persistence of behavior when environmental changes disrupt responding. Studies have shown that RTC varies as a function of the reinforcement associated with the context, with higher rates and magnitudes of reinforcement generating greater response persistence. Resistance to change has been shown to be related to reinstatement, or the increase in responding during extinction when responses are followed by noncontingent reinforcement. Little research has investigated whether punishers have equivalent yet opposite effects as reinforcers on response persistence and reinstatement. The present study investigated the effects of electric shock punishment on resistance to change and …

Behind The Curtain: Fetishism And The Production Of Virtual Reality Treatment For Ptsd, Janice Haaken, Mariel Stadick

Psychology Faculty Publications and Presentations

Virtual Iraq/Afghanistan, a virtual reality (VR) exposure therapy designed for the treatment of combat-related PTSD, has generated wide public interest in the wake of growing concerns over mental health problems among service members. Enlisting concepts from the fields of cultural studies and psychoanalytic film criticism, the paper interprets the VR therapy program as a form of technology fetishism within the expanding apparatus of military mental health operations. Even as the program seeks to expose the “invisible wounds of war,” the stories produced through this use of visual culture conform closely to hegemonic military accounts of the psychological effects of combat.

The Importance Of Serotonergic And Adrenergic Receptors For The Induction And Expression Of One-Trial Cocaine-Induced Behavioral Sensitization, Krista N. Rudberg

Electronic Theses, Projects, and Dissertations

Addiction is a complex process in which behavioral sensitization may be an important component. While the behavioral effects of sensitization are well established, the intricate neurobiology of the phenomenon is still largely unknown. Dopamine systems mediate the induction of behavioral sensitization in adult rats, but there is a large amount of evidence showing that other neurotransmitter systems also modulate the induction process. For example, the α1b-adrenergic and 5-HT_2A receptor systems are known to modulate the sensitized responding of adult rats, but the roles that these receptor systems play in the induction and expression of behavioral sensitization during the preweanling …

Practicing Emotionally Biased Retrieval Affects Mood And Establishes Biased Recall A Week Later, Janna N. Vrijsen, Paula T. Hertel, Eni Sabine Becker

Psychology Faculty Research

Cognitive Bias Modification (CBM) can yield clinically relevant results. Only few studies have directly manipulated memory bias, which is prominent in depression. In a new approach to CBM, we sought to simulate or oppose ruminative processes by training the retrieval of negative or positive words. Participants studied positive and negative word pairs (Swahili cues with Dutch translations). In the positive and negative conditions, each of the three study trials was followed by a cued-recall test of training-congruent translations; a no-practice condition merely studied the pairs. Recall of the translations was tested after the training and after 1 week. Both recall …

Sex Differences In The Relationship Between Planum Temporale Asymmetry And Corpus Callosum Morphology In Chimpanzees (Pan Troglodytes): A Combined Mri And Dti Analysis, William D. Hopkins, A. M. Hopkins, M. Misiura, E. M. Latash, M. C. Mareno, S. J. Schapiro, Kimberley A. Phillips

Psychology Faculty Research

Increases brain size has been hypothesized to be inversely associated with the expression of behavioral and brain asymmetries within and between species. We tested this hypothesis by analyzing the relation between asymmetries in the planum temporale (PT) and different measures of the corpus callosum (CC) including surface area, streamline count as measured from diffusion tensor imaging, fractional anisotropy values and the ratio in the number of fibers to surface area in a sample of chimpanzees. We found that chimpanzees with larger PT asymmetries in absolute terms had smaller CC surface areas, fewer streamlines and a smaller ratio of fibers to …

Distress, Circadian Rhythms, Immunity, And Survival In Presurgical Breast Cancer Patients., Whitney Nicole Rebholz

Electronic Theses and Dissertations

Women with breast cancer experience significant stress related to diagnosis and treatment, which may negatively affect physiology (e.g., circadian, endocrine, and immune) and contribute to cancer progression. Demographic (e.g., ethnic minority) and neighborhood factors can contribute to cancer-related stress. African American women with breast cancer experience more adverse disease pathology and earlier mortality; however, factors that explain these disparities rarely have been explored. It is hypothesized that psychosocial stressors (i.e., ethnicity, neighborhood stress, and cancerrelated stress) will be related to one another. Associations of psychosocial stress with physiological disruption are posited with regard to circadian, endocrine, and immune function. It …

Behavioral Reactions To Emotional And Physical Infidelity: An Evolutionary Perspective, Mandy Walsh Walsh

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis examined the effects of sex and type of partner infidelity, including both physical (i.e., sexually involved with another person) and emotional (i.e., emotionally involved with another person) infidelity, on mate abandonment behaviors. Previous research has demonstrated sex differences in emotional responses to infidelity, where men react more negatively to physical infidelity and women react more negatively to emotional infidelity. While various studies have investigated perceived behavioral reactions using imagined scenarios, this study expands current research by utilizing actual retrospective reports. It was hypothesized that males would engage in significantly more mate abandonment behaviors after experiencing a physical infidelity, …

I Matter, As Does The World: Critical Consciousness In Higher Education, Myra Dutko

Dissertations

This dissertation describes how graduate students in a community organizing class move along the critical consciousness pathway. Critical consciousness in the academic arena is critical to the development of democratic participation and agency in students. Critical consciousness is the ability to see, judge and act on issues of injustice in order to create social change. In addition, this research examines what barriers arise in that process. Research participants from an urban, private university in the Midwest narrate the creation of a learning environment and the process of moving towards critical consciousness awakening through journaling and focus group discussions. The data, …

The Weapon Focus Effect: Testing An Extension Of The Unusualness Hypothesis, Curt A. Carlson, William E. Pleasant, Dawn R. Weatherford, Maria A. Carlson, Jane E. Bednarz E. Bednarz

Psychology Faculty Publications (Archived)

The weapon focus effect (WFE) occurs when a weapon distracts eyewitnesses, harming memory for the perpetrator and other details. One explanation is that weapons are unusual in most contexts, and unusual objects distract eyewitnesses. We extended this unusualness hypothesis to include typical objects used in a distinctive manner, as criminals often make use of a typical object as a weapon (e.g., tire iron, beer bottle). Undergraduates (N = 963) viewed a video depicting a man with a handgun, distinctive object, typical object and action, or typical object used as a weapon. Only the handgun reduced eyewitness identification accuracy relative to …

An Examination Of The 16pf Validity Scales As Predictors Of The Scale Of Accurate Personality Prediction (Sapp), Katherine E. Schmieder

Theses and Dissertations

The Scale of Accurate Personality Prediction (SAPP) was derived from the 16 Personality Factor Questionnaire (16-PF) as a measure of self-knowledge by comparing the degree of similarity of a participant’s predicted and obtained 16 PF results. The purpose of this study was to examine the utilization of the16PF validity scales as potential predictors of an individual’s score on the Scale of Accurate Personality Prediction (SAPP). A series of multiple regression analyses were performed on the current database of 641 respondents. Additionally, to provide additional validity, the database was split into two halves, and the multiple regression analyses were run on …

A Further Analysis Of Commission Errors During Discrete Trial Training, Tavy Alisa Matthews

Theses and Dissertations

Treatment integrity has been manipulated in various ways to evaluate its impact on intervention effectiveness. Studies have compared different types of integrity failures and levels of treatment integrity in various contexts and behavioral interventions. Evaluations include differential reinforcement of alternative behavior, child compliance, and discrete trial training. However, further research is needed to establish the point at which integrity becomes detrimental to intervention effectiveness. The purpose of this study was to conduct a parametric analysis (i.e., 100%, 75%, 50%, & 25%) of treatment integrity to examine the effects of commission errors during discrete trial training. Three participants, ages 35 - …

Secular But Not Superficial : An Overlooked Nonreligious/Nonspiritual Identity., Daniel G. Delaney

Electronic Theses and Dissertations

Since Durkheim’s characterization of the sacred and profane as “antagonistic rivals,” the strict dichotomy has been framed in such a way that “being religious” evokes images of a life filled with profound meaning and value, while “being secular” evokes images of a meaningless, self-centered, superficial life, often characterized by materialistic consumerism and the cold, heartless environment of corporate greed. Consequently, to identify as “neither religious nor spiritual” runs the risk of being stigmatized as superficial, untrustworthy, and immoral. Conflicts and confusions encountered in the process of negotiating a nonreligious/nonspiritual identity, caused by the ambiguous nature of religious language, were explored …

The Void Between Us, Hannah D. Blumer

Bachelor of Fine Arts Senior Papers

My interactive thesis installation, The Void Between Us, addresses the topic of human connection in relationship to the body. The human body marks a physical barrier between one’s self and others. While we exist in the same physical sphere as one another, our minds are isolated in our own self-centered versions of reality. Our bodies allow us to perceive others and be perceived—including having verbal communications—and, therefore, could be seen as helpful or restrictive in the social world. However, our bodies also allow us to engage in physical interactions with others, such as sex, which is a means to …

Attachment Styles And Trust Propensity In Females With Borderline Personality Disorder, Jacob Matthew White

Graduate Theses and Dissertations

Borderline Personality Disorder (BPD) is one of the most frequently encountered and complex disorders in mental health care. Interpersonal impairment is a central issue for individuals with BPD. This complex disorder has received negative stigma along with historically more females than males receiving this diagnosis (Linehan, 1993). Therefore, this study examined a clinical sample of 30 females diagnosed with BPD. Through the collection of data this study used the following measures: a basic demographic questionnaire gathering specific age, ethnicity, current relationship status, parental relationship status, the Experiences in Close Relationships Scale (ECR; Brennan, Clark & Shaver, 1998), and the Propensity …

Differential Parental Investment, Jose C. Yong, Norman P. Li

Research Collection School of Social Sciences

Differences in minimum obligatory parental investment contributed by men and women lead the sexes to diverge in their sexual strategies and affective experiences, although under certain conditions, men’s mating preferences converge with women’s. This chapter first describes necessary or obligatory parental investment, examines the origins of sex differences in obligatory parental investment, describes examples of such differences across a range of species, and highlights the consequences of these differences in terms of human sexual strategies, conflicts, and affective experiences.

Animals In The Wild, Brittany Samson

The Transdisciplinary STEAM+ Journal

As a photographer, I am extremely interested in the concept of perception and I let this concept drive most of my artistic work. I present four images from my photographic series “Animals in the Wild,” which explore this idea of perception. These four images: Giraffe, Dinosaur, Buffalo, and Bunny—are drastically varied photos that include no real animals, but instead beg the mind to perceive shapes, colors, figure, and coincidence as an animal.

Insect Consciousness: Commitments, Conflicts And Consequences, Colin Klein, Andrew B. Barron

Animal Sentience

Our target article, “Insects have the capacity for subjective experience,” has provoked a diverse range of commentaries. In this response we have collated what we see as the major themes of the discussion. It is clear that we differ from some commentators in our commitments to what subjective experience is and what the midbrain is capable of. Here we clarify where we stand on those points and how our view differs from some other influential perspectives. The commentaries have highlighted the most lively areas of disagreement. We revisit here the debates surrounding whether the cortex is essential for any form …
