The Relationship Between Parenting Styles And Conduct Disorder In Hispanic Families, Jessica Vera-Rios
The Relationship Between Parenting Styles And Conduct Disorder In Hispanic Families, Jessica Vera-Rios
Walden Dissertations and Doctoral Studies
Conduct disorder (CD) is prevalent among American teens, yet limited research has been conducted on Hispanics adolescents. Based on social learning theory and parenting theory, the purpose of this quantitative study was to examine the relationship amongst parenting styles, Hispanic cultural influences, and CD. A sample of 85 parents with adolescents receiving juvenile probation services in South Texas were surveyed to assess their parenting style, Hispanic cultural influences, and their adolescent's symptoms of CD. The Mexican Parent Questionnaire measured the independent variable: parenting styles. The Brief Acculturation Rating Scale for Mexican Americans-II measured the independent variable: Hispanic cultural influences. The …
Horses In Therapy: The Practice Of Equine Facilitated Psychotherapy, Mandi J. Turner
Horses In Therapy: The Practice Of Equine Facilitated Psychotherapy, Mandi J. Turner
Graduate School of Professional Psychology: Doctoral Papers and Masters Projects
Horses are being used in psychotherapy at increasing rates despite a lack of evidence establishing efficacy of the practice (Anestis, Anestis, Zawilinski, Hopkins, & Lilienfeld, 2013; Selby & Smith-Osborne, 2013). Without common and consistent practices based on a working theory of how Equine Facilitated Psychotherapy (EFP) creates change, it is unknown how varied the practice is across the United States (Anestis et al., 2013). A lack of studies establishing efficacy leaves providers to determine effectiveness based on anecdotal evidence that may be at risk for bias (Lilienfeld, Ritschel, Lynn, Cautin, & Latzman, 2014). The American Psychological Association (APA) provides recommended …
Not All Fun And Games: Sexism And College Women's Alcohol Consumption, Hannah R. Hamilton
Not All Fun And Games: Sexism And College Women's Alcohol Consumption, Hannah R. Hamilton
Dissertations
Previous research has suggested that racial discrimination (Pascoe & Smart Richman, 2009) and sexist experiences (Zucker & Landry, 2007) are related to increased alcohol consumption. However, ambivalent sexism theory suggests that there are two forms of sexism (Glick & Fiske, 1996; 1997). While hostile sexism refers to overtly negative attitudes towards women, benevolent sexism refers to positively valenced attitudes towards women that still serve to reaffirm masculine dominance. Therefore, the current studies explore the differential effects of experiencing hostile vs. benevolent sexism on college women's alcohol consumption using correlational (Study 1) and quasi-experimental (Study 2) methodologies. In addition, the current …
Hardiness, Adult Attachment Style, And Burnout In Nurses, Kristy A. Negri
Hardiness, Adult Attachment Style, And Burnout In Nurses, Kristy A. Negri
Walden Dissertations and Doctoral Studies
The current nursing shortage is a pressing crisis that is expected to worsen over time. A key reason nurses leave nursing is burnout. The purpose of this study was to investigate personality hardiness and adult attachment style in relation to the development of burnout in licensed professional nurses. Hardiness theory and attachment theory indicated that each provided protection against burnout, but no research has been conducted to examine both factors in relation to burnout in nurses. Research Question 1 asked if there was a relationship between attachment style and total hardiness score; Research Question 2 asked if there was a …

Sleep Disturbances And Depression Severity In Patients With Parkinson’S Disease, Daniel Kay, Jared J. Tanner, Dawn Bowers
Sleep Disturbances And Depression Severity In Patients With Parkinson’S Disease, Daniel Kay, Jared J. Tanner, Dawn Bowers
Faculty Publications
Objectives: Parkinson’s disease (PD) is a multisystem movement disorder associated with sleep disturbance and depression. Sleep disturbances and depression severity share a bidirectional association. This association may be greater in individuals who are more vulnerable to the deleterious consequences of sleep disturbance and depression severity. We investigated whether the association between sleep disturbances and depression severity is greater in patients with PD than in matched controls (MC).
Materials and Methods: The study sample (N = 98) included 50 patients with idiopathic PD and 48 age-, race-, sex-, and education-matched controls. Sleep disturbances were assessed using self-reported total sleep time (TST) …
Effects Of Long-Term Participation In Tennis On Cognitive Function In Elderly Individuals, Scott Culpin
Effects Of Long-Term Participation In Tennis On Cognitive Function In Elderly Individuals, Scott Culpin
Theses: Doctorates and Masters
Many studies have reported the relationship between exercise and cognition with conflicting results. This may be due to differences in intervention durations, session lengths, intensities, and type of exercise. It has been suggested that exercises requiring greater cognitive demand such as football, basketball and racquet sports, are protective against cognitive decline, compared to less cognitively demanding exercises such as swimming, cycling and running, however, research concerning exercise types are currently limited. The present study tested the hypothesis that elderly individuals who had been regularly playing tennis more than 10 years, would have greater cognitive function than those who had been …
The Moral Motivations Of Negative Attitudes Toward Transgender People, Hailey Annette Hatch
The Moral Motivations Of Negative Attitudes Toward Transgender People, Hailey Annette Hatch
Dissertations and Theses @ UNI
Transgender individuals are at higher risk for experiencing sexual assault and police brutality than the general population (National Coalition for Anti-Violence Programs, 2013). These brutal acts are likely the result of negative attitudes. Negative attitudes toward transgender people are related to individual differences in psychological authoritarianism, political conservatism, religiosity, and low personal contact with sexual minorities (Norton & Herek, 2013). This study explored underlying moral mechanisms that may also contribute to negative attitudes toward transgender people – specifically mechanisms involving generalized disgust (i.e., purity) and harm. Moral foundations theory (Haidt & Graham, 2007) suggests that disgust is the underlying mechanism …
Resilience In Undergraduate Students: The Relation Between Personality, Social Support, And Cortisol Levels, Elisheva Joy Havlik
Resilience In Undergraduate Students: The Relation Between Personality, Social Support, And Cortisol Levels, Elisheva Joy Havlik
Dissertations and Theses @ UNI
The purpose of the current study was to investigate resilience in relation to personality, social support, and cortisol levels in response to a stress induction in a sample of 174 undergraduate students. It was hypothesized that resilience would be positively related to personality traits and perceived social support, and also would predict cortisol levels at baseline, reactivity to stress induction, and recovery after stress induction. Additionally, exploratory analyses investigated the moderating effects between variables to explain the process of resilience further. Participants completed self-report questionnaires (i.e. the CD-RISC, BFI, and the MPSS), provided saliva samples via a passive drool collection …
Pokémon Go As A Positive Virtual Reality Game: Promoting Cognitive, Affective, And Empathic Benefits, Rachel Carpenter
Pokémon Go As A Positive Virtual Reality Game: Promoting Cognitive, Affective, And Empathic Benefits, Rachel Carpenter
UNF Graduate Theses and Dissertations
Video game popularity and time playing in children, adolescents, and adults is steadily increasing due to heightened accessibility, advanced technological game design, and a rising sedentary lifestyle among Americans. The advent of exergames and virtual reality paradigms has led to a new wave of mobile video games that can be played anywhere, involve the combination of mobility and gaming, and may be used to improve cognition, affect, and perhaps empathy. The aim of the present study was to examine if the exergame Pokémon Go would improve visual and verbal working memory, attention, positive and negative affect, and empathy. Additionally, the …
Treatment Analysis Of A Captive Male Jaguar (Panthera Onca), Megan Colleen Morris
Treatment Analysis Of A Captive Male Jaguar (Panthera Onca), Megan Colleen Morris
UNF Graduate Theses and Dissertations
Large carnivores in human care have been reported to engage in stereotypic behaviors. Such behavior is thought to be correlated with high stress levels, in part, due to captive environments limiting opportunities for functional consequences and environmental stimuli. Moreover, there are several arguments stating that stereotypic behaviors can be indicative of poor welfare, as they can often have severe negative emotional and physical effects on the animal. The first portion of this study included a five-phase treatment analysis which evaluated whether environmental manipulations decrease the frequency of stereotypic behaviors including pacing, over-grooming and tail-sucking exhibited by a single male jaguar …
Jealousy In Dogs? Evidence From Brain Imaging, Peter Cook, Ashley Prichard, Mark Spivak, Gregory S. Berns
Jealousy In Dogs? Evidence From Brain Imaging, Peter Cook, Ashley Prichard, Mark Spivak, Gregory S. Berns
Animal Sentience
Domestic dogs are highly social and have been shown to be sensitive not only to the actions of humans and other dogs but to the interactions between them. We used the C-BARQ scale to estimate dogs’ aggressiveness, and we used noninvasive brain imaging (fMRI) to measure activity in their amygdala (an area involved in aggression). More aggressive dogs had more amygdala activation data while watching their caregiver give food to a realistic fake dog than when they put the food in a bucket. This may have some similarity to human jealousy, adding to a growing body of evidence that differences …
Researchers, Not Dogs, Lack Control In An Experiment On Jealousy, Jennifer Vonk
Researchers, Not Dogs, Lack Control In An Experiment On Jealousy, Jennifer Vonk
Animal Sentience
Cook and colleagues (2018) have developed a clever method to measure fMRI in awake dogs in response to a number of interesting stimuli. As a result, they are able to determine neural correlates of observable behavior. They report that dogs may experience something akin to jealousy because they show greater amygdala activation in response to food being given to a fake dog versus food being placed in a bucket. However, several critical controls are missing which prevent the authors from being able to speak of jealousy.
Finding The Green-Eyed Monster In The Brain Of A Dog, Peter Singer
Finding The Green-Eyed Monster In The Brain Of A Dog, Peter Singer
Animal Sentience
That dogs show behavior suggestive of jealousy has long been known and has been demonstrated under controlled conditions. Cook et al. have now shown arousal in the amygdala when dogs see a caregiver feeding another dog. This finding has ethical significance in two respects. First, the consideration shown by the investigators for the welfare of their experimental subjects sets an example for other researchers using animals. Second, the greater understanding of the emotional lives of animals should lead to more concern for their needs.
Jealousy, Competition, Or A Contextual Cue For Reward?, Thomas R. Zentall
Jealousy, Competition, Or A Contextual Cue For Reward?, Thomas R. Zentall
Animal Sentience
Emotions are difficult to assess, even in humans. The attribution of jealousy in an animal like a dog is especially difficult because performance of a particular behavior in the context of another animal receiving a reward may not be easily distinguishable from intra-species competition or simply a response to a contextual cue for the availability of reward. The authors provide distinguishing evidence in the form of fMRI data to show that in the presence of a “fake” dog being fed, there is bilateral activation in the amygdala, an area associated with anxiety, anger, fear, and even jealousy in humans.
What Can The Social Emotions Of Dogs Teach Us About Human Emotions?, Dean Mobbs
What Can The Social Emotions Of Dogs Teach Us About Human Emotions?, Dean Mobbs
Animal Sentience
It has long been believed that social emotions such as guilt and jealousy are only expressed in humans. In the case of jealousy, its adaptive value has been linked to the prevention of sexual infidelity or fairness. So why would dogs feel jealousy? I suggest that understanding how social emotions have been bred into dogs can help us understand our own emotions, including their functionality — and potentially their mechanisms.
Can Neuroimaging In Dogs Have Practical Implications?, Tiffani J. Howell
Can Neuroimaging In Dogs Have Practical Implications?, Tiffani J. Howell
Animal Sentience
Jealousy, or at least aggression, can be observed in dogs using neuroimaging techniques, but this response attenuates quickly following repeated exposure to the aggression-inducing stimulus. This may have a practical application. Early socialisation as a puppy, and habituation as an adult dog, could help prevent undesirable behaviours such as predatory behaviour. It is unclear whether these processes are the same, and affected only by the dog’s age. Neuroimaging could help us understand whether the same neurological processes underlie socialisation and habituation, and whether self-rewarding behaviours such as predatory behaviour could be stopped using socialisation/habituation techniques.
Lessons From Behaviour For Brain Imaging, Carolyn J. Walsh
Lessons From Behaviour For Brain Imaging, Carolyn J. Walsh
Animal Sentience
Integrating physiological and behavioural arousal with social context is fundamental to understanding affect in dogs. Cook et al. (2018) have made a worthy start towards illuminating the neural basis of dog affect underlying resource loss. However, their study depends on retrospective behaviour reports versus direct testing, and an interpretation of differential neural activation that is based on too few dogs. Research groups conducting canine brain-imaging work might: (1) consider collaborative approaches to augment sample sizes and replicability, and (2) take a recent lesson from dog behavioural research regarding a more cautious approach to applying functional labels to physiological and/or behavioural …
On Jealousy, Envy, Sex Differences And Temperament In Humans And Dogs, Eddie Harmon-Jones, Sylvia K. Harmon-Jones
On Jealousy, Envy, Sex Differences And Temperament In Humans And Dogs, Eddie Harmon-Jones, Sylvia K. Harmon-Jones
Animal Sentience
Cook, Prichard, Spivak, and Berns (2018) find that dogs’ levels of trait aggression are positively correlated with their amygdala activation when observing their caregivers giving a food to a fake dog. The authors conclude that this may provide neural evidence in dogs for the experience of jealousy, an emotion that some psychologists consider to be unique to humans. Here we explain the difference between the emotions of jealousy and envy, suggesting some ideas for future experiments that may help disentangle the experience of jealousy from that of envy in dogs. We also propose ideas for future research that may yield …
Inferring Emotion From Amygdala Activation Alone Is Problematic, Thomas F. Denson
Inferring Emotion From Amygdala Activation Alone Is Problematic, Thomas F. Denson
Animal Sentience
Cook et al. investigated neural responses in domestic dogs in an experiment designed to elicit jealousy. Relative to a control condition, watching the dogs’ caregivers feed a fake dog activated the amygdala bilaterally. Dogs rated higher in dog-directed aggressiveness showed larger initial amygdala activation. Amygdala activity in this context is insufficient evidence to infer that the dogs experienced jealousy or even negative affect. The experimental design does not provide an adequate level of control to infer the presence of jealousy.
Can A Dog Be Jealous?, Yaoguang Jiang, Annamarie W. Huttunen, Michael L. Platt
Can A Dog Be Jealous?, Yaoguang Jiang, Annamarie W. Huttunen, Michael L. Platt
Animal Sentience
Whether humans alone experience complex emotions like jealousy or envy remains hotly debated, partly because of the difficulty of measuring them without a verbal report. Cook, Berns and colleagues use functional brain imaging to identify in dogs neural responses very similar to those evoked by jealousy in humans. When dogs see their caregiver reward a facsimile dog, their amygdala is activated and the strength of this response predicts aggressive behavior — just as jealousy leads to aggression in humans. The authors conclude that dogs feel something very similar to human jealousy. This novel and creative study tackles one of the …
Jealousy? Or Just Hostility Toward Other Dogs? The Risks Of Jumping To Conclusions, James A. Serpell
Jealousy? Or Just Hostility Toward Other Dogs? The Risks Of Jumping To Conclusions, James A. Serpell
Animal Sentience
Cook et al. (2018) provide a fascinating demonstration of amygdala activation in dogs when they witnessed their owners giving food to another (fake) dog, but not when they placed food in a bucket. Dogs’ neurological responses were positively correlated with their reported levels of ‘dog-directed aggression’ as measured by the C-BARQ, and dogs with initially strong amygdala responses habituated on subsequent trials. The authors interpret their findings as possible evidence for an emotion akin to jealousy in dogs. However, alternate interpretations involving either dog aggression/fear or emotional responses to food seem more plausible and avoid the welfare risks associated with …
What Would We Like To Know By Imaging The Brains Of Dogs?, Ralph Adolphs
What Would We Like To Know By Imaging The Brains Of Dogs?, Ralph Adolphs
Animal Sentience
Using fMRI to study emotions in animals is important, fascinating, and fraught with methodological and conceptual problems. Cook et al. are doing it, and there is no question that they and others will be doing it better and better as time goes on. Where will this lead us? What could fMRI in principle tell us about the minds of nonhuman animals?
What Is It Like To Be A Jealous Dog?, Emanuela Prato Previde, Paola Valsecchi
What Is It Like To Be A Jealous Dog?, Emanuela Prato Previde, Paola Valsecchi
Animal Sentience
Jealousy is a good candidate for comparative studies due to its clear adaptive value in protecting social bonds and affective relationships. Dogs are suitable subjects for investigating the evolution of jealousy, thanks to their rather sophisticated socio-cognitive abilities — which in some cases parallel those reported for human infants — and thanks to their long-lasting relationship with humans. The work of Cook and colleagues (2018) addresses the issue of jealousy in dogs through the lens of neuroscience, examining the relationship between the amygdala and jealousy. Their experiment has a number of methodological flaws that prevent distinguishing jealousy from other internal …
Dogs Aren’T Jealous – They Are Just Asking For Accurate Information, Karen L. Overall
Dogs Aren’T Jealous – They Are Just Asking For Accurate Information, Karen L. Overall
Animal Sentience
Awake fMRI offers us a unique opportunity to view and understand how dogs see the world and use the information in it. Given the limitations of behavioral assays and the small sample sizes inherent in these studies, labeling of patterns of canine behaviors using pop psychology terms may actually interfere with our understanding of canine brains and obscure for us a more parsimonious but exciting interpretation of canine behavior. We should use this window into how dogs think wisely.

Fill-In-The-Blank-Emotion In Dogs? Evidence From Brain Imaging, Alexandra Horowitz, Becca Franks, Jeff Sebo
Animal Sentience
What is needed to make meaningful claims about an animal’s capacity for subjective experience? Cook et al. (2018) attempt to study jealousy in dogs by placing them in a particular context and then seeing whether they display a particular brain state. We argue that this approach to studying jealousy falls short for two related reasons. First, the relationship between jealousy and the selected context is unclear. Second, the relationship between jealousy and the selected brain state (indeed, any single brain state) is unclear. These and other issues seriously limit what this study can show. It is important not to see …
Displaying Jealous Behavior Versus Experiencing Jealousy, Judit Abdai, Ádám Miklósi
Displaying Jealous Behavior Versus Experiencing Jealousy, Judit Abdai, Ádám Miklósi
Animal Sentience
Jealous behavior is the manifestation of complex behavioral interactions initiated by an individual who aims to maintain an important social relationship that is threatened by a rival. Researchers prefer to focus on the emotion thought to control this behavior, “jealousy,” before understanding the mechanisms of the behavior. Researchers conducting recent behavioral studies on jealous behavior in dogs are still struggling to find strong experimental evidence. Thus, the positive correlation between amygdala activation and reported aggression in dogs described in Cook et al.’s target article is far from constituting evidence for “jealousy” in dogs.

Situating The Study Of Jealousy In The Context Of Social Relationships, Christine E. Webb, Frans B. M. De Waal
Animal Sentience
Whereas the feelings of other beings are private and may always remain so, emotions are simultaneously manifested in behavior, physiology, and other observables. Nonetheless, uncertainty about whether emotions can be studied adequately across species has promoted skepticism about their very presence in other parts of the animal kingdom. Studying social emotions like jealousy in the context of the social relationships in which they arise, as has been done in the case of animal empathy, may help dispel this skepticism. Empathy in other species came to be accepted partly because of the behavioral similarities between its expression in nonhuman animals and …
The Degeneracy Of Behavior And The Rise Of Neuroimaging To Measure Affective States In Dogs, Peter F. Cook, Gregory S. Berns
The Degeneracy Of Behavior And The Rise Of Neuroimaging To Measure Affective States In Dogs, Peter F. Cook, Gregory S. Berns
Animal Sentience
It is gratifying and significant that so many scientists from diverse fields are arguing in-depth regarding a particularly complex set of social emotions in a non-human animal. Emotions play a fundamental role in decision making and information processing. Neuroimaging is important in understanding the cognitive and emotional worlds of non-human animals and can help measure covert emotions lacking clear behavioral correlates. Various experimental approaches could clarify the relative importance of attachment and aggression in jealousy and whether the phenomenon we measured is more akin to human envy or jealousy. Reverse inference from amygdala activation is probably justified because behavior is …
