Drosophila Tone Preference During Oviposition, Alexa Christine Decker

Theses, Dissertations and Culminating Projects

Evidence shows that Drosophila melongaster take into account the environmental factors such as substance, temperature, texture, and direct threats in order to provide protection for their offspring; young drosophila utilize experienced drosophila's olfactory cues for informed site selection. Their site selection is indicative of what drosophila view as beneficial. Since they have near-field hearing, drosophila may integrate sound into their deciding factors. If drosophila utilize sound as a deciding factor then a tone within their hearing range and similar to the tone their wings produce during flight such as a 250 Hz tone could have positive or negative associations. In …

A Biometric Analysis Of Mate Choice Copying In People, Jonathan Lenhardt

Theses, Dissertations and Culminating Projects

Mate choice copying is the notion that a person or animal, after observing another choosing a romantic or sexual partner, will perceive that partner as more attractive and possibly attempt to acquire that same partner for themselves. Using measurement of pupil size in response to the presentation of pictures of men and women both alone and with a neutral or admiring partner, it was hypothesized that such a biometric measure could substantiate previous research that has supported the evidence of mate choice copying in people. This study's methodology complements that of previous studies utilizing questionnaires to measure the attractiveness of …

Bottlenose Dolphin (Tursiops Truncatus) Behaviors In The Presence Of Active And Non-Active Shrimp Trawlers In The Mississippi Sound, Crysta M. Lorenz

Honors Theses

Bottlenose dolphins, Tursiops truncatus, are reported to have close associations with shrimp trawlers worldwide. The goal of this study was to assess differences in the behavior for bottlenose dolphins between activity states of shrimp trawlers in the Mississippi Sound. During active trawling, nets are actively gathering the catch closely behind the trawler, which provide feeding opportunities for bottlenose dolphins. Non-active groups are not able to take advantage of feeding prospects and display fewer feeding behaviors and maintain a farther distance than active trawler groups. Video of trawlers were collected from the Mississippi Wild Dolphin Project and analyzed for feeding …

How To Go Beyond The Body: An Introduction, Guy Dove

Faculty and Staff Scholarship

Embodied cognition represents one of most important theoretical developments in contemporary cognitive science. Many cognitive processes appear to be influenced by body morphology, emotions, and sensorimotor systems. This perspective is supported by an ever increasing collection of empirical studies that fall into two broad classes: one consisting of experiments that implicate action, emotion, and perception systems in seemingly abstract cognitive tasks and the other consisting of experiments that demonstrate the contribution of bodily interaction with the external environment to the performance of such tasks.

Now that embodied cognition is fairly well established, the time seems right for assessing its further …

Hindsight Bias And Guilt, Jessica Frances Johnson

Graduate Theses/Dissertations

This study is an examination of the relationship between hindsight bias and posttraumatic guilt. There is some evidence that guilt following a trauma is caused, at least in part, by the hindsight bias. However, the researchers behind this theory have not tested this theory utilizing the hypothetical experimental design for hindsight bias or tested their conception of hindsight bias in terms of foreseeability and inevitability. This study attempted to do just that. Participants were presented with a scenario about a friend in a car accident. Participants in the foresight group received no outcome. Participants in the hindsight groups were told …

Exploring The Relationship Between Early Childhood Attentional Control And Language Ability, Jaima S. Price

Electronic Theses and Dissertations

Relatively few studies have investigated the relationship between early childhood attentional control and later cognitive outcomes, especially language development. The current study is an investigation of the relationship between the executive functioning (EF) component of attentional control and language ability in the second year of life. More specifically, the predictive nature of two aspects of attentional control, attentional focus and resistance to distraction, was be the primary focus of the proposed study. Although it was expected that children both high in attentional focus and resistance to distraction would have significantly superior language development than infants with lower attentional capacities, analyses …

Evidence Consistent With The Multiple-Bearings Hypothesis From Human Virtual Landmark-Based Navigation, Martha R. Forloines, Kent D. Bodily, Bradley R. Sturz

Psychology: Faculty Publications

One approach to explaining the conditions under which additional landmarks will be learned or ignored relates to the nature of the information provided by the landmarks (i.e., distance versus bearings). In the current experiment, we tested the ability of such an approach to explain the search behavior of human participants in a virtual landmark-based navigation task by manipulating whether landmarks provided stable distance, stable direction, or both stable distance and stable direction information. First, we incrementally shaped human participants’ search behavior in the presence of two ambiguous landmarks. Next, participants experienced one additional landmark that disambiguated the location of the …

Visitor Behavior In The Living Treehouse At Zoo Atlanta, Montana Holland, Rena Roberson, Cassandra Teal, Krystal Bailey, Suma Mallavarapu, Lauren Taglialatela

Symposium of Student Scholars

The aim of this project was to determine whether visitors utilize conservation and education displays in the Living Treehouse at Zoo Atlanta. Approximately 34% of visitors read displays and watched animals on exhibit. This subset of visitors spent significantly more time watching animals than reading displays [F(1, 44) = 15.62, p < 0.001, ƞ2 = 0.26]. Limited interaction with relatively static displays may not lead to the intended change in knowledge and conservation attitudes among zoo visitors. Interactive displays (instead of static signage) separated from animal exhibits may be more effective in attracting and holding attention and delivering conservation and …

Effects Of 17Β-Estradiol On Learning And Memory And Strategy Use During A Hole Board Spatial Navigation Task In Aged Male Rats, Megan Berthiaume

Seton Hall University Dissertations and Theses (ETDs)

Treatment with 17β- estradiol has been shown to ameliorate age related deficits in spatial learning and memory as well as to promote the use of an allocentric strategy during spatial navigation. While the majority of research using 17β- estradiol has been done using females rodents, there have been studies showing an improvement in spatial learning and memory and promoted use of allocentric strategies in spatial navigation in males as well. In males testosterone (T) is metabolized into estradiol by aromatase. As circulating levels of T decline with aging there is less available T to be metabolized into estradiol. The current …

Humour In Power-Differentiated Intergroup Wage Negotiation, Mendiola Teng-Calleja, Cristina J. Montiel, Marshaley J. Baquiano

Psychology Department Faculty Publications

This research examined the role of humour in power-differentiated wage bargaining conversations. We collected transcripts of wage bargaining between the local labour union and management negotiators of a multinational beverage company operating in the Philippines. Through conversation analysis, we determined how both parties utilised humor to challenge or maintain power relations even as both labour and management worked towards a wage bargaining agreement. Findings show that humour was used to maintain intergroup harmony, subvert authority and control the negotiation. Our findings may be useful for labour organisations and multinational corporations that operate in Southeast Asian countries with historically tumultuous labour …

Domestic Dogs ' (Canis Lupus Familiaris) Evaluation Of Moral And Immoral Actors, Katherine E. Ford

Honors Projects

A sense of morality, or values predisposing what is right (fair, just, kind) and what is wrong (unfair, cruel, dishonest), appears universally across all humankind. All major cultures share support for some values, such as self-respect, respect for others, and 'the golden rule'treat others how you wish to be treated-and disdain for some sins, such as murder, theft and dishonesty (Kinnier, Kernes & Dautheribes, 2000). Some moral behaviors, such as inequity aversion, the tendency to do no hann and cooperation are found to exist in virtually all human adults. But where does morality come from? Is it uniquely human or …

Adaptation Of D2 Dopamine Receptors Following Acute Ethanol, Brian Behnke, Scott Steffensen

Journal of Undergraduate Research

The purpose of my experiment was To study the effects that ethanol (EtOH) has on the D2 receptors (D2R) in the nucleus accumbens (NAc) and ventral tegmental area (VTA), in order to determine if D2 is a key contributor to an alcohol addictive state.

An Analysis Of Free-Will, Matthew Campbell

Honors Theses

The following paper is a broad analysis of the concept of free-will. Free-will can be defined as having the ability to act outside of necessity, such that one can be the ultimate author and initiator of their actions and decisions. Stated differently, possessing free-will allows an individual to be held accountable for their behaviors, because those behaviors are the result of something controllable within the individual, rather than something external to the individual and beyond their control.

A belief in free-will is widely assumed, for we hold individuals both legally and morally accountable for their actions. Nevertheless, it remains a …

The Effects Of Genes On The Stress Response, S. Andrew Aston

Journal of Undergraduate Research

Corticotropin-releasing hormone (CRH) acts as one of the primary coordinators of the physiological, behavioral, and autonomic stress response. CRH secreted from the paraventricular nucleus (PVN) of the hypothalamus initiates the hypothalamic pituitary adrenal (HPA) axis response by signaling the secretion of adrenocorticotropic hormone (ACTH) from the anterior pituitary. ACTH then travels to the adrenal glands, leading to the release of cortisol Thus, CRH plays a key role in preparing an individual to adaptively respond to a stressful situation.

Using The Stroop Effect To Examine The Effect Of Words To Which Humans Are Sensitive On Cognitive Conflict, Stacia Fritz

Honors College Theses

The purpose of experiment one was to test the effects of drink consumed (glucose, artificial sweetener, or water) and stimuli (food or non-food) on cognitive conflict. Glucose has been known to better cognitive functioning, and preoccupation with food worsens cognitive functioning on a food-related task. We hypothesized that participants who received glucose and non-food stimuli will perform best on the cognitive tests, and participants who received aspartame and food-stimuli will perform worst on the cognitive tests. Participants were each given an 8 oz. drink to consume, shown six minutes of stimuli, performed an “X-word” Stroop test, shown six more minutes …

Do Dogs Possess Self-Control?, Stephanie Aubuchon, Jessica Kraut, Ellen Furlong, Facutly Advisor

John Wesley Powell Student Research Conference

Each year 6 to 8 million pet dogs enter shelters, and approximately 60% are euthanized. Unfortunately, many dogs are taken to shelters or euthanized due to behavioral problems. Identifying dogs who may have these behaviors allows owners to be informed and prepared for these dogs, reducing the number returned to shelters. One way to identify potential problems may be through measuring self-control in dogs. We have adapted our methods from a similar method used with capuchin monkeys (Bramlett et al., 2012). We constructed a wheel with food that rotated in front of dog subjects. The dog had the choice to …

Moral Reasoning In Dogs, Katherine Ford, Ellen Furlong, Faculty Advisor

John Wesley Powell Student Research Conference

A sense of morality, values predisposing right (fair, just, kind) from wrong (unfair, cruel, dishonest) appears universally across all humankind (Kinnier, Kernes & Dautheribes, 2000). But where does morality come from? Is it uniquely human or do we share some moral values with nonhuman animals? To explore these questions domestic dogs—nonhumans with exceptional social cognitive skills—were tested for moral values through a replication of a study on moral reasoning in human infants (Hamlin & Wynn, 2011). Dogs watched a puppet show with a moral (helpful) and immoral (hinderer) actor. Dogs looked longer when the neutral puppet chose to associate with …

Good Dog! Applications Of Dog Science, Brenden Wall, Anthony Bohner, Jeffrey Toraason, Ellen Furlong, Faculty Advisor

John Wesley Powell Student Research Conference

Each year 6 to 8 million pet dogs enter shelters, and unfortunately, many are returned to shelters, or euthanized, due to behavioral problems. Many behavioral problems can be alleviated if dogs get exercise; however, some owners cannot provide dogs sufficient exercise. Further, some dogs may be physically unable to exercise. One possible solution is to provide dogs with mental exercise. We are currently developing a series of touchscreen computer tasks with the hope that they provide mental stimulation and can be made available to owners via a tablet application. As of now, a few dogs in our lab have learned …

Machines And Agency: Understanding The Ai Ethics Problem, Addison T. Rahn

Senior Honors Theses

Mankind has long been interested in the unique, the strange, and the new; perhaps nothing more fully encompasses this interest than recent work on developing Artificial Intelligence (AI). With this research, however, comes a great many questions. Are AIs alive? Are AIs moral agents? Can machines be held legally culpable for their actions? These questions, and more, continue to be a topic of much debate in the academic community, and will no doubt remain of interest for years to come. It is the purpose of this research project, however, to investigate the far-reaching effects of this academic debate. While the …

Treatment Of Cognitive Dysfunction In Major Depressive Disorder - A Review Of The Preclinical Evidence For Efficacy Of Selective Serotonin Reuptake Inhibitors, Serotonin-Norepinephrine Reuptake Inhibitors And The Multimodal-Acting Antidepressant Vortioxetine, Alan Pehrson, Steven C. Leiser, Maria Gulinello, Elena Dale, Yan Li, Jessica A. Waller, Connie Sanchez

Department of Psychology Faculty Scholarship and Creative Works

Although major depressive disorder is primarily considered a mood disorder, depressed patients commonly present with clinically significant cognitive dysfunction that may add to their functional disability. This review paper summarizes the available preclinical data on the effects of antidepressants, including monoamine reuptake inhibitors and the multimodal antidepressant vortioxetine, in behavioral tests of cognition such as cognitive flexibility, attention, and memory, or in potentially cognition-relevant mechanistic assays such as electroencephalography, in vivo microdialysis, in vivo or in vitro electrophysiology, and molecular assays related to neurogenesis or synaptic sprouting. The available data are discussed in context with clinically relevant doses and their …

Identifying Genes Involved In Suppression Of Tumor Formation In The Planarian Schmidtea Mediterranea, Erin Dorsten

Best Integrated Writing

Twelve-Month-Old Infants’ Encoding Of Goal And Source Paths In Agentive And Non-Agentive Motion Events, Laura Lakusta, Susan Carey

Department of Psychology Faculty Scholarship and Creative Works

Across languages and event types (i.e., agentive and nonagentive motion, transfer, change of state, attach/detach), goal paths are privileged over source paths in the linguistic encoding of events. Furthermore, some linguistic analyses suggest that goal paths are more central than source paths in the semantic and syntactic structure of motion verbs. However, in the nonlinguistic memory of children and adults, a goal bias shows up only for events involving intentional, goal-directed, action. Three experiments explored infants’ nonlinguistic representations of goals and sources in motion events. The findings revealed that 12-month-old infants privilege goals over sources only when the event involves …

The Perception Of Symmetry In Depth: Effect Of Symmetry Plane Orientation, Bart Farell

Biomedical and Chemical Engineering - All Scholarship

The visual system is sensitive to symmetries in the frontoparallel plane, and bilateral symmetry about a vertical axis has a particular salience. However, these symmetries represent only a subset of the symmetries realizable in three-dimensional space. The retinal image symmetries formed when viewing natural objects are typically the projections of three-dimensional objects—animals, for example—that have a symmetry in depth. To characterize human sensitivity to depth symmetry, experiments measured observers’ ability to discriminate stereo displays that were symmetrically distributed in depth and those that were asymmetrically distributed. Disparity values were distributed about one of four planes passing through the z-axis and …

Ouch, That Hurts: Childbirth-Related Pain Management And The Inappropriate Replacement Of Traditional Obstetrical Knowledge In Kumaon, Uttarakhand, India, Sabrina Zionts

Independent Study Project (ISP) Collection

Throughout India, obstetrical knowledge and practice has been developed and passed down by generations of women. In many Indian societies, traditional birth attendants, or dais, remain the gatekeepers of childbirth-related knowledge. Yet with the push towards institutional delivery, traditional knowledge and practices are being increasingly replaced with modern and Western ones. While the trend of hospital deliveries has yielded positive health outcomes, its socio-cultural consequences remain unclear. Situated in Uttarakhand’s Kumaon Himalayas, this study employs a bio-social framework and begins to reveal these consequences. Using labor pain management as an entry point, this study argues that the push towards institutional …

Financial Literacy And College Students: An Exploration Of College Students’ Attitudes, Behaviors, Influences And Preparedness For Financial Decisions After Graduation, Kerry Quirk

Honors Projects in Finance

Financial literacy is the level of understanding an individual has for different financial topics, including but not limited to, investment vehicles, retirement accounts, saving, budgeting, credit and taxes, and the use of such knowledge to change one’s financial behavior to create a more positive financial position for the future. Past research has shown that college students consistently have low levels of financial literacy. They also lack knowledgeable influences on their financial education. Because many college students will soon enter the workforce after graduation and will be responsible for managing their own salary, retirement accounts and investment options, they can be …

Microhabitat Use Affects Goby (Gobiidae) Cue Choice In Spatial Learning Task, G. E. White, C. Brown

Sentience Collection

This study investigated whether spatial learning ability and cue use of gobies (Gobiidae) from two contrasting habitats differed in a spatial task. Gobies were collected from the spatially complex rock pools and dynamic, homogenous sandy shores. Fishes were trained to locate a shelter under the simulated threat of predation and it was determined whether they used local or extra-maze (global) and geometric cues to do so. It was hypothesized that fishes from rock pools would outperform fishes from sandy shores in their ability to relocate shelter and the two groups would differ in their cue use. It was found that …

Motor Skill Learning Between Selection And Execution., Jörn Diedrichsen, Katja Kornysheva

Brain and Mind Institute Researchers' Publications

Learning motor skills evolves from the effortful selection of single movement elements to their combined fast and accurate production. We review recent trends in the study of skill learning which suggest a hierarchical organization of the representations that underlie such expert performance, with premotor areas encoding short sequential movement elements (chunks) or particular component features (timing/spatial organization). This hierarchical representation allows the system to utilize elements of well-learned skills in a flexible manner. One neural correlate of skill development is the emergence of specialized neural circuits that can produce the required elements in a stable and invariant fashion. We discuss …

Seasonal Change In The Avian Hippocampus., David F Sherry, Scott A Macdougall-Shackleton

Brain and Mind Institute Researchers' Publications

The hippocampus plays an important role in cognitive processes, including memory and spatial orientation, in birds. The hippocampus undergoes seasonal change in food-storing birds and brood parasites, there are changes in the hippocampus during breeding, and further changes occur in some species in association with migration. In food-storing birds, seasonal change in the hippocampus occurs in fall and winter when the cognitively demanding behaviour of caching and retrieving food occurs. The timing of annual change in the hippocampus of food-storing birds is quite variable, however, and appears not to be under photoperiod control. A variety of factors, including cognitive performance, …

Seeing People, Seeing Things: Individual Differences In Selective Attention, Miranda May Mcintyre

Open Access Theses

Individuals differ in the extent to which they attend to their physical and social environments, but little empirical work has measured these differences at a cognitive level. To address this gap, two studies explored the association between attentional processes and Person and Thing Orientations. The first study measured visual selective attention toward person- and thing-related image components. In the second study, participants provided written responses about a set of images; linguistic analyses were conducted to assess attentional bias toward interest-congruent content. The results from both studies support motivated attention as a process through which interests in physical and social environments …
