In Search Of The Neurobiological Substrates For Social Playfulness In Mammalian Brains, Stephen M. Siviy, Jaak Panksepp

Psychology Faculty Publications

Play behavior is a fundamental and intrinsic neurobehavioral process in the mammalian brain. Using rough-and-tumble play in the juvenile rat as a model system to study mammalian playfulness, some of the relevant neurobiological substrates for this behavior have been identified, and in this review this progress. A primary-process executive circuit for play in the rat that includes thalamic intralaminar nuclei, frontal cortex and striatum can be gleaned from these data. Other neural areas that may interact with this putative circuit include amygdala, ventral hypothalamus, periaqueductal gray (PAG), and deep tectum, as well as ascending dopamine systems which participate in all …

Serotonin, Motivation, And Playfulness In The Juvenile Rat, Stephen M. Siviy, Loren M. Deron, Chelsea R. Kasten

Psychology Faculty Publications

The effects of the selective 5HT1A agonist 8-OH-DPAT were assessed on the play behavior of juvenile rats. When both rats of the test pair were comparably motivated to play, the only significant effect of 8-OH-DPAT was for play to be reduced at higher doses. When there was a baseline asymmetry in playful solicitation due to a differential motivation to play and only one rat of the pair was treated, low doses of 8-OH-DPAT resulted in a collapse of asymmetry in playful solicitations. It did not matter whether the rat that was treated initially accounted for more nape contacts or fewer …

Long Term Effects Of Chronic Variable Stress Administered During Different Developmental Stages In Mice, Henry Boeh

Dissertations (1934 -)

A number of studies have suggested that the occurrence of past trauma can increase an individual's chance of developing PTSD from a new traumatic experience later in life. Trauma that occurs during childhood appears to have a particularly strong effect on this risk increase. Furthermore, conditioned fear responses have been shown to incubate over extended periods of time in animal models. To further investigate the role these phenomena play in the development of PTSD, this study exposed juvenile and adult mice to 7 days of chronic variable stress (CVS). One month later, a Pavlovian delay fear conditioning procedure was used …

The Steroid/Peptide Theory Of Social Bonds: Integrating Testosterone And Peptide Responses For Classifying Social Behavioral Contexts, Sari M. Van Anders, Katherine L. Goldey, Patty X. Kuo

Department of Child, Youth, and Family Studies: Faculty Publications

Hormones, and hormone responses to social contexts, are the proximate mechanisms of evolutionary pathways to pair bonds and other social bonds. Testosterone (T) is implicated in trade-offs relevant to pair bonding, and oxytocin (OT) and arginine vasopressin (AVP) are positively tied to social bonding in a variety of species. Here, we present the Steroid/Peptide Theory of Social Bonds (S/P Theory), which integrates T and peptides to provide a model, set of predictions, and classification system for social behavioral contexts related to social bonds. The S/P Theory also resolves several paradoxes apparent in the literature on social bonds and hormones: the …

Effects Of Chronic Variable Stress Across Developmental Stages In Mice, Sheryl Jayne Stevens

Master's Theses (2009 -)

Posttraumatic Stress Disorder (PTSD) is a response to trauma exposure that involves a number of symptoms that can be highly impairing to affected individuals. Only a subset of those exposed to traumatic events will develop the disorder, which is conceptualized as developing via conditional fear. Research into factors predisposing for PTSD is needed. Furthermore, little work has been done to investigate predisposing factors in children more specifically. This research tests the effects of stress exposure on subsequent fear learning, across developmental stages in mice, as a model for PTSD. Juvenile and adult male mice were exposed to chronic variable stress …

Picture Recognition Of Food By Macaques (Macaca Silenus), Peter G. Judge

Faculty Journal Articles

Pictorial representations of three-dimensional objects are often used to investigate animal cognitive abilities; however, investigators rarely evaluate whether the animals conceptualize the two-dimensional image as the object it is intended to represent. We tested for picture recognition in lion-tailed macaques by presenting five monkeys with digitized images of familiar foods on a touch screen. Monkeys viewed images of two different foods and learned that they would receive a piece of the one they touched first. After demonstrating that they would reliably select images of their preferred foods on one set of foods, animals were transferred to images of a second …

Indicators Of Age, Body Size And Sex In Goat Kid Calls Revealed Using The Source–Filter Theory, Elodie F. Briefer, Alan G. Mcelligott

Sentience Collection

The source–filter theory is an important framework recently applied to the study of animal vocalisations, which links the mode of vocal production to call parameters. Vocalisations can be good indicators of a sender’s characteristics, such as identity, body size, age, and even hormonal status and affective states. For these reasons, applied vocal communication research would greatly benefit from adopting the source–filter theory approach to identify key call parameters linked to physical and physiological characteristics of domestic animals. Here, we introduce the source–filter theory through a detailed analysis and interpretation of goat contact calls during development. In mammals, vocal development is …

Vocabulary Development In Greek Children: A Cross-Linguistic Comparison Using The Language Development Survey, Christina F. Papaeliou, Leslie Rescorla

Psychology Faculty Research and Scholarship

This study investigated vocabulary size and vocabulary composition in Greek children aged 1; 6 to 2; 11 using a Greek adaptation of Rescorla's Language Development Survey (LDS; Rescorla, 1989). Participants were 273 toddlers coming from monolingual Greek-speaking families. Greek LDS data were compared with US LDS data obtained from the instrument's normative sample (Achenbach & Rescorla, 2000). Vocabulary size increased markedly with age, but Greek toddlers appeared to get off to a slower start in early word learning than US children. The correlation between percentage word use scores in Greek and US samples was moderate in size, indicating considerable overlap …

Embodied Cultural Cognition: Situating The Study Of Embodied Cognition In Socio-Cultural Contexts, Angela K. Y. Leung, Lin Qiu, Lay See Ong, Kim-Pong Tam

Research Collection School of Social Sciences

Embodiment research has demonstrated that cognition is grounded in bodily interactions with the environment and that abstract concepts are tied to the body’s sensory and motor systems. Building upon this embodiment perspective and advancing our understanding, we discuss the extension of embodied cultural cognition. We propose that some associations between bodily experiences and abstract concepts are not randomly formed; rather, the development of such associations is situated in a socio-cultural context, informed by cultural imperatives, values, and habits. We draw evidence supporting this view of embodied cultural cognition in body–mind linkages manifested in construal of emotions, time perception, person perception, …

Memory For Emotional Images: Mechanisms Of Episodic Processing And Its Psychophysiological Correlates, Gregory E. Devore

Loma Linda University Electronic Theses, Dissertations & Projects

Negative emotional stimuli are usually better remembered than neutral emotional stimuli. Previous examination of binding theory found no differences in recall for pure lists of taboo and neutral words. A similar result was found with equivalent recognition memory performance between pure lists of negative, positive, and neutral images. The current research is designed to test the predictions of binding theory using negative and neutral visual stimuli in mixed lists. A rapid serial visual presentation paradigm and recognition memory item-discrimination tasks are used. Binding theory predicts differences in recognition memory performance between arousing and neutral images in mixed lists, but not …

The Impact Of Pomegranate On Memory Dysfunction After Cardiac Surgery, Sapna Patel

Loma Linda University Electronic Theses, Dissertations & Projects

Background: Studies have shown a decline in certain cognitive abilities in individuals diagnosed with heart disease of any type or etiology. This decline is observed as the disease progresses (Muller, Grobbee, Aleman, Bots & van der Schouw, 2006; Ernest et al., 2006), as well as after certain interventions, such as coronary artery bypass grafting (CABG) and heart valve surgery. In recent years, there has been a great deal of emphasis on the beneficial effects of pomegranate on health, including diseases of the brain and the heart. Few, however, have explored the impact of pomegranate on cognitive functions. Thus, the current …

Myelomeningocele And The Neuropsychological Functioning Of Bilingual Children, Claudia Resendiz

Loma Linda University Electronic Theses, Dissertations & Projects

Myelomeningocele is the most common and most severe form of spina bifida, affecting the brain and spinal cord of millions of children. Children of Hispanic background have the highest prevalence rate of this condition. Despite this fact, research that examines the cognitive profiles of Hispanic children with myelomeningocele is limited. A review on bilingualism and neurocognitive performance suggests that a cognitive advantage is present among those who are able to learn and utilize two languages. Although some have investigated the neuropsychological performance of children with myelomeningocele, research has yet to examine whether a bilingual cognitive advantage is present among bilingual …

Lateralization Of Emotion, Reaction Time, And Skin Conductance Responsiveness, Kimberley Erin Rose

Loma Linda University Electronic Theses, Dissertations & Projects

Bilateral presentations of brief (250 ms), unmasked emotional and neutral stimuli were examined in two experiments with primarily female samples. Reaction time and accuracy data were used to measure perception of emotion and skin conductance response (SCR) was used to measure experience of emotion. Both words and pictures were used to account for hemispheric differences in language and visuospatial dominance. Response time was faster to emotional pictures than words. Reaction time and speeded accuracy data did not support right hemisphere hypothesis (RHH) or valence hypothesis (VH) in the expected manner. Data suggested emotion caused greater interference under speeded conditions in …

Integrating The Development Of Children And Gestalt Therapy, Jennifer J. Thompson

Loma Linda University Electronic Theses, Dissertations & Projects

There are many theories that have contributed to what we know about the development of children; for instance, theoretical diversity supports the complexities of human nature. A child's developmental level will impact his ability to relate. Gestalt theory supports the child's phenomenological view by focusing on the here-and-now of what is happening in the therapeutic environment. Most of what a child will do is in response to a need or want. The child will work toward fulfilling that need. The child may develop maladaptive ways to fulfill his needs based on the environment in which he lives. Gestalt play therapy …

The Commonalities Of Creativity And Suicide In College Students, Christopher W. Drapeau, Daniel Debrule

Modern Psychological Studies

More than 1,000 college students die by suicide each year. Commonly found among these suicides are students who are highly creative, mentally ill, and attending highly competitive schools. Research has demonstrated that the risk of suicide is most acute in students displaying hypomania, impulsivity, psychosis, and a personality trait called psychoticism. Interestingly, these four risk factors are also exhibited in highly creative college students. Hypomania was the most significant contributor to creativity and suicide among the four variables. Elevations in hypomanic symptoms were found among the most creative students and those at risk for repeated suicide attempts. A self-report questionnaire …

Parental Grief And Loss And The Medical Staff Relationship: A Function Of Attachment, Peter Christopher Gleason

Loma Linda University Electronic Theses, Dissertations & Projects

Each year, too many parents must face the horrific ordeal of having to prepare for the death of their child; thought to be the most traumatic event in the life of an adult (Widger & Picot, 2008). It is in the desperate hours just prior to death that these parents, for many reasons, reach out for support to the medical staff around them. This process, particularly if negative, can leave scars that parents will carry for a lifetime (N. Contro, Larson, Scofield, Sourkes, & Cohen, 2002; Tinsley, et al., 2008). However, there appear to be factors that serve to lessen …

Cerebral Lateralization Determines Hand Preferences In Australian Parrots, Culum Brown, Maria Magat

Sentience Collection

Individual preference for the use of one limb over the other to explore the environment or manipulate objects is common trait among vertebrates. Here, we explore the hypothesis that limb preference is determined by the engagement of a particular cerebral hemisphere to analyse certain stimuli. We recorded the eye and foot preferences of 322 individuals from 16 species of Australian parrots while investigating potential food items. Across all species, eye preferences explained 99 per cent of the variation in foot use in Australian parrots. The vast majority of species showed significant relationships between eye and foot preferences at the population …

Language Typology And Sentence Frame Effects On Motion Verb Interpretation In Grade Schoolers, Emma C. Kelty

Master's Theses

Most English descriptions of motion events express manner in the main verb and path in a prepositional phrase, as in “She skips out of the house”. However, the same event can be described differently if a different syntactic frame is used: “She exits the house”. While young children have been found to interpret novel motion verbs according to the syntactic frame information, adults have been found to rely somewhat more on the overall language pattern, or typology (Hohenstein et al., 2004; Naigles & Terrazas, 1998). Grade schoolers have not been examined in this paradigm, and their linguistic abilities suggest that …

Insightful Problem Solving In An Asian Elephant, Preston Foerder, Marie Galloway, Tony Barthel, Donald E. Moore Iii, Diana Reiss

Publications and Research

The ‘‘aha’’ moment or the sudden arrival of the solution to a problem is a common human experience. Spontaneous problem solving without evident trial and error behavior in humans and other animals has been referred to as insight. Surprisingly, elephants, thought to be highly intelligent, have failed to exhibit insightful problem solving in previous cognitive studies. We tested whether three Asian elephants (Elephas maximus) would use sticks or other objects to obtain food items placed out-of-reach and overhead. Without prior trial and error behavior, a 7-year-old male Asian elephant showed spontaneous problem solving by moving a large plastic cube, on …

Factors Associated With Obesity Treatment Adherence In Mexican-American Women, Julia Austin

Psychology ETDs

The current study examined environmental and socio-cultural factors postulated to predict adherence to a standard weight management program in Mexican-American women. In addition, the study gathered preliminary data on the effectiveness of the program with the study sample. One-hundred overweight or obese Mexican-American women in the Albuquerque area completed a pre-treatment intake and were enrolled in the group-based treatment. Of the 100 women who enrolled, 82 attended at least one treatment session. In terms of the predictors of treatment adherence, income was found to positively predict attendance in multivariate analyses. In addition, neighborhood satisfaction positively predicted reported walking goals completed, …

Manipulating Paradigm And Attention Via A Mindfulness Meditation Training Program Improves P300-Based Bci., Daniel Ryan Berry

Electronic Theses and Dissertations

To date, only one study has situationally bolstered attentional resources in an effort to improve P300-BCI performance. The current study implements a 4-week Mindfulness Meditation Training Program (MMTP) as a nonmedicinal means to increase concentrative attention and to reduce lapses of attention; MMTP is expected to improve P300-BCI performance by enhancing attentional resources and reducing distractibility. A second aim is to test the efficacy of the checkerboard paradigm (CBP) against the standard row-column paradigm (RCP). Online results show that MMTP had greater accuracies than CTRL and that CBP outperformed the RCP. MMTP participants provided greater amplitude positive target responses, but …

Of Ice And Men: Chilling Leadership Tales Of Four Great Explorers, Singapore Management University

Perspectives@SMU

Following a brief pause after the Age of Exploration, the desire of human beings to reach every corner of their earth, however remote, was revived when expeditions to the two Polar Regions began in the 19^th century. Participants of such harsh expeditions might have been carrying on the mantle of adventure or seeking fame, but they also provide fine examples for some very important lessons, said author Ragnar Kvam.

School Refusal Behavior: A Phenomenological Study Of Latino/A Children's Experiences, Mary Ashley Angelo

Electronic Theses and Dissertations

School refusal behavior (SRB) is a subset of absenteeism in which children either altogether refuse to attend school or experience great difficulty remaining in class for the duration of the school day. Child motivated SRB is a growing problem that now affects between 5% and 28% of children and adolescents at some point during their lives. The effects of SRB can extend well beyond the classroom. Long-term, SRB can lead to delinquency and psychiatric, occupational, and marital problems in adulthood. Additionally, children who consistently exhibit SRB are more likely to drop out of school, thereby limiting their career choices and …

Aging And Selective Attention In Causal Learning, Melanie Waldrop Asriel

Masters Theses & Specialist Projects

This study investigated age differences in generalization of causal value employing similarity as a cue to causality. Exemplars from six food categories (A+, B-, C+, D-. E+, F-) were presented to both young and older adults in two contiguous training phases. Training Phase 1 included exemplars from categories A+, B-, C+, D-. Training Phase 2 included exemplars from A+, B-, E+, F-. Foods in the “+” categories were paired with an outcome of sickness and foods in the “-” categories were not paired with sickness. Tests of causal judgment and exemplar recognition were conducted. For causal judgment, individual exemplars experienced …

Comprehension Of Functional Support By Enculturated Chimpanzees Pan Troglodytes, Anna M. Yocom, Sarah T. Boysen

Sentience Collection

Studies of causal understanding of tool relationships in captive chimpanzees have yielded disparate findings, particularly those reported by Povinelli & colleagues (2000) for tool tasks by laboratory chimpanzees. The present set of experiments tested nine enculturated chimpanzees on three versions of a support task, as described by Povinelli (2000), during which food rewards were presented in different experimental configurations. In Experiment 1, stimulus pairs included a choice between a cloth with a reward on the upper right corner or with a second reward off the cloth, adjacent to a corner, with the second pair comprised of a cloth with food …

A Longitudinal Study Of Fetal Tissue Transplantation Surgery For The Treatment Of Parkinson's Disease: Can Quality Of Life And Optimism At Baseline Predict Patient Outcome 10 Years Later?, Emily B. Fazio

Electronic Theses and Dissertations

Parkinson's disease (PD) is a chronic and progressive condition that affects the physical, emotional, and social functioning of individuals. Freed et al. (2001) conducted a double-blind sham-controlled trial to investigate the effectiveness of fetal tissue transplantation for the treatment of advanced PD. The authors of that study examined the effects of the surgery across the dimensions of physical and neurological functioning. A quality of life (QoL) study was conducted to determine if there were differences in QoL when comparing those who received the fetal tissue transplantation with those who received the sham surgery (McRae et al., 2004).

Moral Cognition In Children An Examination Of The Possible Impact Of School Didactic Philosophies, Smit S. Shah

HIM 1990-2015

The purpose of this thesis is to examine the effects that Montessori and public school environments have on the moral cognition of children and to assess the differences using modified moral dilemma stories. Through the analysis of these children's responses on moral dilemma stories this thesis reveals that there are stark and statistically significant differences in the children's responses on two of the three stories. The Montessori children scored higher on the morality level and the answers reflected altruism over authority on story one and story three. Through these results the researcher surmised that school environment can have an impact …
