Campus Safety: Assessing And Managing Threats, Mario Scalora, Andre Simons, Shawn Vanslyke

Mario Scalora Publications

Since the shootings at Virginia Tech, academic institutions and police departments have dedicated substantial resources to alleviating concerns regarding campus safety. The incident in Blacksburg and the similar tragedy at Northern Illinois University have brought renewed attention to the prevention of violence at colleges and universities.

Campus professionals must assess the risk posed by known individuals, as well as by anonymous writers of threatening communications. The authors offer threat assessment and management strategies to address the increased demands faced by campus law enforcement, mental health, and administration officials who assess and manage threats, perhaps several simultaneously.

Evolution Of The Cerebellar Cortex: The Selective Expansion Of Prefrontal-Projecting Cerebellar Lobules, J. H. Balsters, E. Cussans, J. Diedrichsen, Kimberley A. Phillips, T. M. Preuss, J. K. Rilling, N. Ramnani

Psychology Faculty Research

It has been suggested that interconnected brain areas evolve in tandem because evolutionary pressures act on complete functional systems rather than on individual brain areas. The cerebellar cortex has reciprocal connections with both the prefrontal cortex and motor cortex, forming independent loops with each. Specifically, in capuchin monkeys cerebellar cortical lobules Crus I and Crus II connect with prefrontal cortex, whereas the primary motor cortex connects with cerebellar lobules V, VI, VIIb, and VIIIa. Comparisons of extant primate species suggest that the prefrontal cortex has expanded more than cortical motor areas in human evolution. Given the enlargement of the prefrontal …

Effects Of Chlordiazepoxide On Predator Odor-Induced Reductions Of Playfulness In Juvenile Rats, Stephen M. Siviy, Courtney L. Steets, Lauren M. Debrouse

Psychology Faculty Publications

The extent to which a non-sedative dose of chlordiazepoxide (CDP) is able to modify the behavioral responses toward a predator odor was assessed in juvenile rats. Play behavior was suppressed and defensive behaviors were enhanced in the presence of a collar previously worn by a cat, when tested 24 hours later in the same context as that where the exposure occurred, and when tested in a context different than that in which the exposure occurred for up to 3 hours after exposure. CDP had no effect on the ability of cat odor to suppress play when rats were tested in …

Effects Of Cb2 Receptor Activation On Variable Chronic Mild Stress (Cms) Induced Depression And Hippocampal Dependant Spatial Learning, Eli Shobin

Psychology Honors Papers

Major Depressive Disorder (MDD) accounts for approximately 10% of all diagnosed chronic illness in the United States. The most common treatments for MDD is serotonergic manipulation via pharmacological treatments such as monoamine oxidase inhibitors (MAO-I) or selective serotonin reuptake inhibitors (SSRI). However, not only have these treatments proven to be ineffective for a portion of the population, but they also fail to treat some of the physiological damages that occur in the hippocampus during MDD due to over-activation of inflammatory cells known as microglia. Activation of the CB2 receptor in the hippocampus has been shown to inhibit microglial cells and …

Neural Activity In The Hippocampus And Perirhinal Cortex During Encoding Is Associated With The Durability Of Episodic Memory, V. A. Carr, Indre Viskontas, S. A. Engel, B. J. Knowlton

Psychology

Studies examining medial temporal lobe (MTL) involvement in memory formation typically assess memory performance after a single, short delay. Thus, the relationship between MTL encoding activity and memory durability over time remains poorly characterized. To explore this relationship, we scanned participants using high-resolution functional imaging of the MTL as they encoded object pairs; using the remember/know paradigm, we then assessed memory performance for studied items both 10 min and 1 week later. Encoding trials were classified as either subsequently recollected across both delays, transiently recollected (i.e., recollected at 10 min but not after 1 week), consistently familiar, or consistently forgotten. …

Recovery Of Sensorimotor Function In Rats Following Acute Rapid Eye Movement Sleep Deprivation And Controlled Cortical Impact, Jaime Lynn Shuster

ETD Archive

Traumatic brain injury (TBI) resulting from bomb blasts and explosions is common among military personnel. The effects of Rapid Eye Movement (REM) sleep deprivation on the sensorimotor behavior and physiological mechanisms related to TBI are unknown. Thirty-two Long Evans rats were randomly assigned to REM sleep deprivation (RSD) with controlled cortical impact (CCI), social isolation (SI) with CCI, or normal housing (NH) with CCI or Sham. Two behavioral tasks [beam walk and bilateral tactile adhesive removal somatosensory (BTARS)] testing motor and sensory function were used to investigate recovery of function. Brain tissue was analyzed using Cresyl Violet stain (cell bodies), …

Parental Cognitive Factors And Treatment Choices For Externalizing Behavior Problems, Danielle R. Hemmings

Theses, Dissertations and Capstones

Understanding the relationship between parental cognitive variables and outcomes related to the treatment of externalizing disorders has received limited attention in the research literature. The present study was completed in order to determine whether the parental cognitive variables of self-efficacy or locus of control were related to the level of involvement parents had in addressing their child’s behavior problems. It was hypothesized that a) parents with external locus of control would be likely to be less involved in their child’s treatment than parents with a more internal locus of control and b) that parents with low parental self-efficacy would be …

Development, Refinement, And Psychometric Properties Of The Attitudes Toward God Scale (Atgs-9), Benjamin T. Wood, Everett L. Worthington, Julie Julia Exline, Ann Marie Yali, Jamie D. Aten, Mark R. Mcminn

Faculty Publications - Doctor of Psychology (PsyD) Program

Perceived relationships with God can be a source of comfort or struggle. To advance the study of spiritual comfort and struggle, we develop the nine-item Attitudes toward God Scale (ATGS-9), and we describe six studies (2,992 total participants) reporting its development and psychometrics. Exploratory and confirmatory factor analyses identified two factors: (1) Positive Attitudes toward God and (2) Disappointment and Anger with God. Subscale scores showed good estimated internal consistency, 2-week temporal stability, and evidence for construct and discriminant validity. Positive Attitudes toward God correlated with measures of religiosity and conscientiousness. Disappointment and Anger with God correlated with negative religious …

Slope-Driven Goal Location Behavior In Pigeons, Daniele Nardi, Kristian P. Nitsch, Verner P. Bingman

Faculty Research and Creative Activity

A basic tenet of principles of associative learning applicable to models of spatial learning is that a cue should be assigned greater weight if it is a better predictor of the goal location. Pigeons were trained to locate a goal in an acute corner of an isosceles trapezoid arena, presented on a slanted floor with 3 (Experiment 1) or 2 (Experiment 2) orientations. The goal could be consistently determined by the geometric shape of the arena; however, its position with respect to the slope gradient varied, such that slope position was not a good predictor of the goal. Pigeons learned …

Implications Of Skinner's Verbal Behavior For Studying Dementia, Jeffrey Buchanan, Daniel Houlihan, Peter J.N. Linnerooth

Psychology Department Publications

Persons with dementia experience continual declines in a number of abilities. Language abilities are particularly hard hit and become increasingly impaired as the underlying disease progresses. These language impairments make verbal communication very challenging for family and professional caregivers. As a result, caregivers may inadvertently punish verbal behavior, thereby exacerbating the deterioration of verbal repertoires. Although the topography of language impairments associated with dementia have been well described, less empirical work has been conducted concerning how to minimize these impairments and their deleterious effects. In 1957 B.F. Skinner outlined his conceptualization of language and cognition in his book Verbal Behavior. …

The Impact Of Adherence To Traditional Masculine Gender Role Norms On Anger And Depression, Matthew Charles Genuchi

Electronic Theses and Dissertations

Large scale studies of the incidence and prevalence of psychological disorders have consistently shown that women meet full DSM-IV criteria for major depressive disorder at twice the rate of men (Kessler et al., 1994; Kessler et al., 2003; NCS-R, 2007; Robins & Reiger, 1991). Some have proposed (Cochran & Rabinowitz, 2000; Kilmartin, 2005; Pollack, 1998) that the current DSM-IV diagnostic criteria do not adequately reflect the depressive symptoms of some men. Men tend to use more externalizing defenses and distracting coping styles to manage negative affect, and anger is hypothesized as an externalizing symptom of a masculine variation of major …

Constructing A Neuroscientific Pastoral Theology Of Fear And Hope, Jason C. Whitehead

Electronic Theses and Dissertations

Contemporary therapeutic circles utilize the concept of anxiety to describe a variety of disorders. Emotional reductionism is a detriment to the therapeutic community and the persons seeking its help. This dissertation proposes that attention to the emotion of fear clarifies our categorization of particular disorders and challenges emotional reductionism. I propose that the emotion of fear, through its theological relationship to hope, is useful in therapeutic practice for persons who experience trauma and PTSD.

I explore the differences between fear and anxiety by deconstructing anxiety. Through this process, I develop four categories which help the emotion of fear stand independent …

Environmental Enrichment Attenuates Nucleus Basalis Lesion Induced Impairments To Attention, Brandee Leianne Kinney-Hurd

Theses Digitization Project

This experiment examined the effects of environmental enrichment on performance in an attention-dependent learning task in rats with selective lesions of the cholinergic nucleus basalis magnocellularis (NBM). The findings demonstrate that environmental enrichment can enhance attention-dependent learning performance in normal animals as well as attenuating NBM lesion-induced impairments otherwise seen following rearing in standard conditions.

Men's Subjective Distress To A Partner's Imagined Indifelity: Testing Evolutionary And Social-Cogntive Hypotheses, Tanner Michael Carollo

Theses Digitization Project

Despite the ability of evolutionary psychology to account of sex differences in infidelity distress, it is challenged to explain the repeated finding that a large number of men do not select sexual infidelity as more distressing than emotional infidelity. The research goal of this thesis was to examine theoretically relevant individual difference variables in men that could possibly account for their reported distress to imagining a romantic partner's sexual and emotional infidelity.

Koans And Levels Of Consciousness, John Rowan

International Journal of Transpersonal Studies

This is a theoretical paper devoted to an examination of the phenomenon of the Zen

koan. First, the existing understanding of the koan will be outlined from a number of

sources. This will be followed by an examination of what the koan would look like from

a structural point of view. Ken Wilber’s outlook will then be used to look at the koan in a

fresh way so that one might see it as a kind of test of the level of consciousness exhibited

by each solution. The latter is related to recent thinking on models in general.

Effects Of Chronic Paroxetine And Fluoxetine Treatment On Markers Of Suicidal Behavior In Adolescent Rats, Leslie Renee Horn

Theses Digitization Project

Major depression is a common problem in adolescents. Unfortunately, one of the most effective antidepressants in adults, the selective serotonin reuptake inhibitor (SSRI) paroxetine, is not clinically effective in pediatric populations. There are many variables that increase the risk of suicide including genetic, social, psychological, and biological factors, making the evaluation of the effect of SSRIs on suicidal behavior difficult to assess in human adolescents. The goal of the present investigation was to compare the effects of paroxetine and fluoxetine in adolescent rats on markers associated with depression and suicidal behavior in humans.

Assessment Of Early Maladaptive Schemas Via A Modified Stroop Task, Yelena Kholodenko

Theses Digitization Project

Processing biases play a major role in the understanding of anxiety disorders. The Schema theory hypothesizes that belief systems, early maladaptive schemas (EMS), cause selective processing of confirmatory information to the exclusion of disconfirmatory information. The current study was the first report attempting to provide empirical support for the measurement of EMS with a subtle cognitive processing assessment such as the Stoop task. A Schema Stroop task was constructed for the purposes of the current study.

Degrees Of Complexity And Flexibility In The Belief System And The Strength Of Identity Attachment To Belief Claims, Craig Allen Bray

Theses Digitization Project

Complexity and flexibility make unique but related contributions to the connection between belief system structure and self structure. This study was concerned with how individuals structure their beliefs. Three scales were combined to provide a measure of belief system complexity and flexibility and then correlated with the card sort results.

The Role Of Slope In Human Reorientation, Daniele Nardi, Nora S. Newcombe, Thomas F. Shipley

Faculty Research and Creative Activity

Studies of spatial representation generally focus on flat environments and visual stimuli. However, the world is not flat, and slopes are part of many natural environments. In a series of four experiments, we examined whether humans can use a slope as a source of allocentric, directional information for reorientation. A target was hidden in a corner of a square, featureless enclosure tilted at a 5° angle. Finding it required using the vestibular, kinesthetic and vis-ual cues associated with the slope gradient. Participants succeeded in the task; however, a large sex difference emerged. Men showed a greater ability in using slope …

Octopuses (Enteroctopus Dofleini) Recognize Individual Humans, Roland C. Anderson, Jennifer A. Mather, Mathieu Q. Monette, Stephanie R.M. Zimsen

Sentience Collection

This study exposed 8 Enteroctopus dofleini separately to 2 unfamiliar individual humans over a 2-week period under differing circumstances. One person consistently fed the octopuses and the other touched them with a bristly stick. Each human recorded octopus body patterns, behaviors, and respiration rates directly after each treatment. At the end of 2 weeks, a body pattern (a dark Eyebar) and 2 behaviors (reaching arms toward or away from the tester and funnel direction) were significantly different in response to the 2 humans. The respiration rate of the 4 larger octopuses changed significantly in response to the 2 treatments; …

Squid Dances: An Ethogram Of Postures And Actions Of Sepioteuthis Sepioidea Squid With A Muscular Hydrostatic System, Jennifer A. Mather, Ulrike Griebel, Ruth A. Byrne

Sentience Collection

A taxonomy of the movement possibilities for any species, within the constraints of its neural and skeletal systems, should be one of the foundations of the study of its behaviour. Caribbean reef squid, Sepioteuthis sepioidea, appear to have many degrees of freedom in their movement as they live in a three-dimensional habitat and have no fixed skeleton but rather a muscular hydrostatic one. Within this apparent lack of constraints, there are regularities and patterns of common occurrences that allow this article to describe an ethogram of the movements, postures and positions of squid. Squid have a combination of bent, …

Vigilance And Antipredator Responses Of Caribbean Reef Squid, Jennifer A. Mather

Sentience Collection

Antipredator responses, especially those of open-ocean squid, have been seldom studied in the natural environment. Sepioteuthis sepioidea, observed by snorkellers near the shore in early morning/late afternoon, produced an average of eight moves of over 1m per hour, apparently mostly antipredator behaviours. Close approaches by herbivorous parrotfish elicited no response in 74% of encounters; otherwise, squid produced agonistic zebra stripes or startle-mantle-dots skin patterns. Predatory bar jack fish caused flight but not zebra displays, and squid usually paled and fled quickly (66%) from snapper. The speed of approach was the best predictor for flight and display responses to snapper, …

Male Territoriality In A Social Sciurid, Cynomys Gunnisoni: What Do Patterns Of Paternity Tell Us?, J. L. Verdolin, C. N. Slobodchikoff

Veterinary Science and Medicine Collection

In many social sciurids, male territoriality confers significant mating advantages. We evaluated resident male paternity in Gunnison’s prairie dogs (Cynomys gunnisoni), a colonial ground-dwelling sciurid, where males and females cooperatively defend territories. Contrary to findings reported for other social sciurids, our results show that territorial resident males do not gain significant reproductive advantages. Resident males sired the majority of offspring from their respective territories only 10.5% of the time. A single non-resident male sired equal or greater number of offspring than any single resident male 71.2% of the time. While adult males were more likely to sire a greater number …

Behavior Of A Solitary Sociable Female Bottlenose Dolphin (Tursiops Truncatus) Off The Coast Of Kent, Southeast England, Sonja Eisfeld, Mark P. Simmonds, Laura R. Stansfield

Ethology Collection

This article provides a report of the behavior of a solitary sociable dolphin studied on the southeast coast of England in 2007. This is the first study of its kind in which behavior of such a nonhuman animal was systematically studied. By the time of this study, this young female was highly interactive with people in the water. People accompanied the dolphin for 18.4% of the 100 hr of observation, and their presence changed her behavior. The study recorded 39 different behaviors; feeding and resting behaviors declined in frequency in the presence of people. In addition, the dolphin exhibited behavior …

Quality Prevails Over Identity In The Sexually Selected Vocalisations Of An Ageing Mammal, Elodie F. Briefer, Elisabetta Vannoni, Alan G. Mcelligott

Ethology Collection

Background: Male sexually selected vocalisations generally contain both individuality and quality cues that are crucial in intra- as well as inter-sexual communication. As individuality is a fixed feature whereas male phenotypic quality changes with age, individuality and quality cues may be subjected to different selection pressures over time. Individuality (for example, morphology of the vocal apparatus) and quality (for example, body size and dominance status) can both affect the vocal production mechanism, inducing the same components of vocalisations to convey both kinds of information. In this case, do quality-related changes to the acoustic structure of calls induce a modification of …

Discourse And Wolves: Science, Society, And Ethics, William S. Lynn

Human and Animal Bonding Collection

Wolves have a special resonance in many human cultures. To appreciate fully the wide variety of views on wolves, we must attend to the scientific, social, and ethical discourses that frame our understanding of wolves themselves, as well as their relationships with people and the natural world. These discourses are a configuration of ideas, language, actions, and institutions that enable or constrain our individual and collective agency with respect to wolves.

Scientific discourse is frequently privileged when it comes to wolves, on the assumption that the primary knowledge requirements are matters of ecology, cognitive ethology, and allied disciplines. Social discourse …

Traumatic Brain Injury And The Effects Of Diazepam, Diltiazem, And Mk-801 On Gaba-A Receptor Subunit Expression In Rat Hippocampus, Cynthia J. Gibson, Rebecca C. Meyer, Robert J. Hamm

Psychology Publications

Background

Excitatory amino acid release and subsequent biochemical cascades following traumatic brain injury (TBI) have been well documented, especially glutamate-related excitotoxicity. The effects of TBI on the essential functions of inhibitory GABA-A receptors, however, are poorly understood.

Methods

We used Western blot procedures to test whether in vivo TBI in rat altered the protein expression of hippocampal GABA-A receptor subunits α1, α2, α3, α5, β3, and γ2 at 3 h, 6 h, 24 h, and 7 days post-injuy. We then used pre-injury injections of MK-801 to block calcium influx through the NMDA receptor, diltiazem to block L-type voltage-gated calcium influx, …
