Laterality Enhances Cognition In Australian Parrots, Maria Magat, Culum Brown

Sentience Collection

Cerebral lateralization refers to the division of information processing in either hemisphere of the brain and is a ubiquitous trait among vertebrates and invertebrates. Given its widespread occurrence, it is likely that cerebral lateralization confers a fitness advantage. It has been hypothesized that this advantage takes the form of enhanced cognitive function, potentially via a dual processing mechanism whereby each hemisphere can be used to process specific types of information without contralateral interference. Here, we examined the influence of lateralization on problem solving by Australian parrots. The first task, a pebble-seed discrimination test, was designed for small parrot species that …

Developing A School Functioning Index For Middle Schools, Amanda Birnbaum, Leslie A. Lytle, Cheryl L. Perry, David Murray, Mary Story

Department of Public Health Scholarship and Creative Works

Despite widespread recognition of schools' role in the healthy development of youth, surprisingly little research has examined the relationships between schools' overall functioning and the health‐related behavior of students. School functioning could become an important predictor of students' health‐related behavior and may be amenable to intervention. This paper describes the development and testing of the School Functioning Index (SFI) as a first step in investigating this question. The index was developed for use with middle schools and conceived as a predictor of students' violent behavior, with the potential for extending research applications to additional health and social behaviors. Using social …

Pain Perception In Fish: Indicators And Endpoints, Lynne U. Sneddon

Aquaculture Collection

Recent evidence has shown that fish display aversive behavioral and physiological reactions and a suspension of normal behavior in response to noxious stimuli that cause pain in other animals and humans. In addition to these behavioral responses, scientists have identified a peripheral nociceptive system and recorded specific changes in the brain activity of fish during noxious stimulation. As a result of these observations teleost fish are now considered capable of nociception and, in some opinions, pain perception. From both an experimental and an ethical perspective, it is important that scientists be able to assess possible pain and minimize discomfort that …

Octopus Insularis (Octopodidae), Evidences Of A Specialized Predator And A Time-Minimizing Hunter, Tatiana S. Leite, Manuel Haimovici, Jennifer A. Mather

Sentience Collection

Shallow-water octopuses have been reported as major predators of motile species in benthonic marine communities, capturing their prey by different foraging techniques. This study assessed for the first time the feeding ecology, foraging behavior, and defensive strategy during foraging, including the use of body patterns, to construct a general octopus foraging strategy in a shallow water-reef system. Octopus insularis was studied in situ using visual observations and video recordings. The diet included at least 55 species of crustaceans (70%), bivalves (17.5%), and gastropods (12.5%); however, only four species accounted for half of the occurrences: the small crabs Pitho sp. (26.8%) …

Response To Displaced Neighbours In A Territorial Songbird With A Large Repertoire, Elodie F. Briefer, Thierry Aubin, Fanny Rybak

Ethology Collection

Neighbour recognition allows territory owners to modulate their territorial response according to the threat posed by each neighbour and thus to reduce the costs associated with territorial defence. Individual acoustic recognition of neighbours has been shown in numerous bird species, but few of them had a large repertoire. Here, we tested individual vocal recognition in a songbird with a large repertoire, the skylark Alauda arvensis. We first examined the physical basis for recognition in the song, and we then experimentally tested recognition by playing back songs of adjacent neighbours and strangers. Males showed a lower territorial response to adjacent neighbours …

The Mirror Effect, The Law Of Attraction, And "Points Of Attraction" That Can Nurture The Evolution Of Human Consciousness, Carroy U. Ferguson

Carroy U "Cuf" Ferguson, Ph.D.

This message has several purposes. First, I want to express my immense joy that Chip Baggett and I are serving as Co-Presidents of AHP since August 16, 2009. In my view, Chip and I are long-time friends, who have a transcendent connection and synergistic energies. My desire and intent is for our co-presidency to mirror the effect(s) of synergistic collaboration as a “point of attraction” that can assist in the evolution of human consciousness across often “perceived personal and societal boundaries” (e.g., race, culture, ethnicity, class, individual and collective belief systems, and dogma). More generally, however, this message is intended …

Effects Of Selection For Cooperation And Attention In Dogs, Márta Gácsi, Paul Mcgreevy, Edina Kara, Ádám Miklósi

Cooperative Behavior Collection

Background: It has been suggested that the functional similarities in the socio-cognitive behaviour of dogs and humans emerged as a consequence of comparable environmental selection pressures. Here we use a novel approach to account for the facilitating effect of domestication in dogs and reveal that selection for two factors under genetic influence (visual cooperation and focused attention) may have led independently to increased comprehension of human communicational cues.

Method: In Study 1, we observed the performance of three groups of dogs in utilizing the human pointing gesture in a two-way object choice test. We compared breeds selected to work while …

Developmental Emergence Of Power-Law Wake Behavior Depends Upon The Functional Integrity Of The Locus Coeruleus, Andrew J. Gall, Badal Joshi, Janet Best, Virginia R. Florang, Jonathan A. Doorn, Mark S. Blumberg

Faculty Publications

STUDY OBJECTIVES:

Daily amounts of sleep and wakefulness are accumulated in discrete bouts that exhibit distinct statistical properties. In adult mammals, sleep bout durations follow an exponential distribution whereas wake bout durations follow a power-law distribution. In infant Norway rats, however, wake bouts initially follow an exponential distribution and only transition to a power-law distribution beginning around postnatal day 15 (P15). Here we test the hypothesis that the locus coeruleus (LC), one of several wake-active nuclei in the brainstem, contributes to this developmental transition.

DESIGN:

At P7, rats were injected subcutaneously with saline or DSP-4, a neurotoxin that targets noradrenergic …

Loss Of Shoaling Preference For Familiar Individuals In Captive-Reared Crimson Spotted Rainbowfish Melanotaenia Duboulayi, Erin Kydd, Culum Brown

Sentience Collection

Captive-reared rainbowfish Melanotonia duboulayi showed no preference for familiar individuals in an experiment examining shoaling preferences. Fortnightly re-examination of the shoaling preferences of the captive-reared population showed that the lack of preference for familiar individuals did not alter over an 8 week period. The same experiment performed on laboratory-reared offspring raised in isolated groups for 8 months since hatching also showed no preference for shoals consisting of familiar individuals. In contrast, trials performed on a wild population of M. duboulayi found a strong preference for familiar shoalmates, a result that is consistent with previous studies. The lack of shoaling preferences …

Confidence Intervals For The Ratio Of Two Exponential Means With Applications To Quality Control, James Albert Polcer,Iii

Student Research Conference Select Presentations

We considered the problem of statistical quality control based on the ratio of two population means. We restrict the discussion for two exponential rates, which are commonly used for modeling failure times of components, machines, or systems. Closed form expressions via the moment generation function (MGF) technique will be presented, and numerical examples will be shown using engineering data sets.

Salivary Cortisol, Psychological Stress And Depressive Symptoms Among Patients Undergoing Colon Cancer Screenings, Allyson Reid

Honors Scholar Theses

As the second leading cause of cancer-related deaths in the United States, colon cancer has a high cure rate if detected early by a colonoscopy (U.S.

Cancer Statistics Working Group, 2007). However, more than 41 million at-risk Americans are not properly receiving colonoscopy screenings according to the recommendations of the Center for Disease Control. This study provides insight into the physiological and psychological benefits of the colonoscopy procedure over and above cancer detection and prevention. Thirty-six patients receiving colonoscopic screening at the University of Connecticut Health Center participated in this study. A questionnaire battery that assessed perceived stress, depressive symptoms, …

Measuring Patient Satisfaction After Providing A Choice Of Nourishment Options Between Meals In A Long-Term Care Setting., Samantha Hutson

Electronic Theses and Dissertations

The purpose of this study was to determine whether providing residents of the James H. Quillen Veterans Affairs Medical Center Community Living Center with a choice of nourishment options between meals would improve their satisfaction with the nourishment administration process. As opposed to being given the same nourishment item each day, residents were offered choices from a nourishment cart based upon their diet order. Sixteen residents completed the pre-survey, participated in the revised nourishment cart system for a 3-week period, and completed the postsurvey. Level of satisfaction was determined by analyzing the responses given by the residents on the pre- …

Visuospatial Reasoning In Toddlers: A Correlational Study Of Door Task Performance, Iris Louella Price

Open Access Dissertations

Previous research using violation-of-expectation paradigms suggests that very young infants have a good understanding of unobserved physical events. Yet toddlers appear to lack this knowledge when confronted with the door task, a visuospatial reasoning task which parallels ones used in the habituation/looking time studies. Many studies have been conducted in an effort to determine why toddlers perform poorly on the door task yet the answer remains unclear. The current study used a correlational approach to investigate door task performance from both psychological (executive function), and neuroscience (prefrontal cortex) perspectives. Children between the ages of 2 ½ - 3 years were …

Animal Behaviour, Animal Welfare And The Scientific Study Of Affect, David Fraser

Emotion Collection

Many questions about animal welfare involve the affective states of animals (pain, fear, distress) and people look to science to clarify these issues as a basis for practices, policies and standards. However, the science of the mid twentieth century tended to be silent on matters of animal affect for both philosophical and methodological reasons. Philosophically, under the influence of Positivism many scientists considered that the affective states of animals fall outside the scope of science. Certain methodological features of the research also favoured explanations that did not involve affect. The features included the tendency to rely on abstract, quantitative measures …

The Effects Of Prenatal Exposure Of Valproic Acid On Cranial Nerve Nuclei: A Rat Model For An Autistic Phenotype, Shannon Pickup

Honors Capstone Projects - All

Autistic spectrum disorder is a term referring to five pervasive developmental disorders characterized by impairment in social interaction, deficits in verbal and non-verbal communication and stereotyped repetitive behaviors and interests. The underlying brain injury that leads to autism is also unknown. The cause is also unknown but appears to be a combination of genetic and environmental factors. A study on prenatal thalidomide exposure found patients exposure on days 20-24 of gestation lead to a 1/3 rate of autism, a huge increase from the 1/150 rate of the general population. The thalidomide data suggests the initial injury leading to autism occurs …

The Effects Of Dolphin Education Programs On Visitors' Conservation-Related Knowledge, Attitude And Behavior, Lance Joseph Miller

Dissertations

Zoological institutions typically exhibit dolphins in educational programs such as dolphin shows and interaction programs. The goal of these programs is to entertain visitors while increasing their conservation-related knowledge, attitude and behavior towards dolphins and the marine environment. The purpose of the current study was to examine dolphin shows and interaction programs in terms of their effectiveness in meeting these goals. A multi-institutional study was conducted at six different facilities throughout the United States. A repeated measures design was used to examine the knowledge, attitude and behavior of visitors before, immediately after and three months following participation in dolphin shows …

Taste Sensitivity To 6-N-Propylthiouracil (Prop) As A Biological Marker For Vulnerability To Stress In Mothers And Children, Deann Jones

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Some people are genetically more vulnerable to stress than others, leading them towards poorer outcomes following stressful events. Mothers' vulnerability to stress may, in turn, influence their children, leading their children towards poor outcomes as well. A biological marker of vulnerability to stress may indicate mothers who are at greater risk for experiencing parenting stress, depression, and less support of the infant's emotional development, and infants who are at greater risk for development of poor emotion regulation and behavior problems. Taste sensitivity to propylthiouracil (PROP) is proposed as a biological marker of stress vulnerability in mothers and children. This research …

Mental Imagery And Basketball: A Comparison Of Cognitive-Specific And Flow Imagery, Evan Welo

Psychology Honors Projects

Flow is a psychological state that is associated with optimal performance. Sports such as basketball are conducive to an individual experiencing flow because they have rules that structure and focus attention. Past research indicates that sports related mental imagery practice improves athletic performance; however few studies to date have systematically included the characteristics of flow in their sports mental imagery interventions. The present study compared the efficacy of a ―flow‖ and a standard basketball mental imagery intervention at improving performance on a basketball-shooting task. No significant differences were found between groups, but both reported increases in flow experiences.

Animal Pleasure And Its Moral Significance, Jonathan Balcombe

Sentience Collection

This paper presents arguments for, and evidence in support of, the important role of pleasure in animals’ lives, and outlines its considerable significance to humankind’s relationship to other animals. In the realms of animal sentience, almost all scholarly discussion revolves around its negative aspects: pain, stress, distress, and suffering. By contrast, the positive aspects of sentience – rewards and pleasures – have been rarely broached by scientists. Yet, evolutionary principles predict that animals, like humans, are motivated to seek rewards, and not merely to avoid pain and suffering. Natural selection favours behaviours that enhance survival and procreation. In the conscious, …

Same-Sex Social Behavior In Meadow Voles: Multiple And Rapid Formation Of Attachments, Annaliese K. Beery, David M. Routman, Irving Zucker

Neuroscience: Faculty Publications

Adult meadow voles (Microtus pennsylvanicus) are solitary in the spring–summer reproductive season, but during winter months, females and males are socially tolerant and aggregate in groups. This behavioral difference is triggered by day length: female meadow voles housed in short, winterlike day lengths form same-sex partner preferences, whereas those housed in long, summer-like day lengths are less social. The present study demonstrates that same-sex social attachments in short day lengths are not exclusive; females formed concurrent attachments with more than one individual, and with non-kin as well as siblings. Partner preferences between females were established within one day of cohousing …

Microsaccade Rate Varies With Subjective Visibility During Motion-Induced Blindness, Po-Jang Hsieh, Peter U. Tse

Dartmouth Scholarship

Motion-induced blindness (MIB) occurs when a dot embedded in a motion field subjectively vanishes. Here we report the first psychophysical data concerning effects of microsaccade/eyeblink rate upon perceptual switches during MIB. We find that the rate of microsaccades/eyeblink rises before and after perceptual transitions from not seeing to seeing the dot, and decreases before perceptual transitions from seeing it to not seeing it. In addition, event-related fMRI data reveal that, when a dot subjectively reappears during MIB, the blood oxygen-level dependent (BOLD) signal increases in V1v and V2v and decreases in contralateral hMT+. These BOLD signal changes observed upon perceptual …

Wild Justice - Honor And Fairness Among Beasts At Play, Marc Bekoff, Jessica Pierce

Social Cognition Collection

This essay challenges science’s traditional taboo against anthropomorphizing animals or considering their behavior as indicative of feelings similar to human emotions. In their new book Wild Justice: The Moral Lives of Animals, the authors argue that anthropomorphism is alive and well, as it should be. Here they describe some activities of animals, particularly animals at play, as clear signs that they have recognizable emotions and moral intelligence. Based on years of behavioral and cognitive research, the authors discuss in their book that animals exhibit a broad repertoire of moral behaviors, including empathy and cooperation, but here they concentrate on the …

Criterial Noise Effects On Rule-Based Category Learning: The Impact Of Delayed Feedback, Shawn W. Ell, David A. Ing, Todd W. Maddox

Psychology Faculty Scholarship

Variability in the representation of the decision criterion is assumed in many category learning models yet few studies have directly examined its impact. On each trial, criterial noise should result in drift in the criterion and will negatively impact categorization accuracy, particularly in rule-based categorization tasks where learning depends upon the maintenance and manipulation of decision criteria. The results of three experiments test this hypothesis and examine the impact of working memory on slowing the drift rate. Experiment 1 examined the effect of drift by inserting a 5 s delay between the categorization response and the delivery of corrective feedback, …

Adult-Young Ratio, A Major Factor Regulating Social Behaviour Of Young: A Horse Study, Alice De Boyer Des Roches, Martine Hausberger

Social Behavior Collection

Background: Adults play an important role in regulating the social behaviour of young individuals. However, a few pioneer studies suggest that, more than the mere presence of adults, their proportions in social groups affect the social development of young. Here, we hypothesized that aggression rates and social cohesion were correlated to adult-young ratios. Our biological model was naturally-formed groups of Przewalski horses, Equus f. przewalskii, varying in composition.

Methodology/Principal Findings: We investigated the social interactions and spatial relationships of 12 one- and two-yearold Przewalski horses belonging to five families with adult-young ratios (AYR) ranging from 0.67 to 1.33. We found …

To See Or Not To See: Prestimulus Α Phase Predicts Visual Awareness, Kyle E. Mathewson, Gabriele Gratton, Monica Fabiani, Diane M. Beck, Tony Ro

Publications and Research

We often fail to see something that at other times is readily detectable. Because the visual stimulus itself is unchanged, this variability in conscious awareness is likely related to changes in the brain. Here we show that the phase of EEG α rhythm measured over posterior brain regions can reliably predict both subsequent visual detection and stimulus-elicited cortical activation levels in a metacontrast masking paradigm. When a visual target presentation coincides with the trough of an α wave, cortical activation is suppressed as early as 100 ms after stimulus onset, and observers are less likely to detect the target. Thus, …
