The Effects Of False Heartbeat Feedback On Moral Judgment, Scott Koenig
The Effects Of False Heartbeat Feedback On Moral Judgment, Scott Koenig
Dissertations, Theses, and Capstone Projects
Research on human morality is at a crossroads, with one side claiming that moral judgment is the result of rational inference and the other side claiming that it is the result of emotion-laden intuition. This study investigated whether emotion drives moral judgment by manipulating a core component of the experience of emotion: physiological arousal. The sample consisted of 77 undergraduate students at Brooklyn College (57% women, 43% men; mean age = 20.1). One group of participants was led to believe their heart was beating quickly, and another group slowly, while they read and evaluated a series of text vignettes depicting …
Consumers' Perception Of Food Containing Insect Protein Affected By Serving Condition And Questionnaire Protocol, Yupeng Gao
LSU Master's Theses
Edible insects are a new sustainable protein source compared to meat. Western consumers show aversion to the prospect of insects as food due to unfamiliarity, food neophobia, and negative emotions. This dissertation research explored consumers’ emotional perception of insect-based food products presented under different testing conditions and examined the influence of other people’s emotional expressions towards consumers’ purchase decisions. To identify and rate emotion intensities, tests were conducted using three presenting formats including text, image, and an actual product; all of which were applied for both cookies containing insects and without insects. In addition to these presenting formats, news of …
Targeting Ampa Receptor Modulation During Early Life Adversity: A Mediator For Threat Associated Memories, Roseanna M. Zanca
Targeting Ampa Receptor Modulation During Early Life Adversity: A Mediator For Threat Associated Memories, Roseanna M. Zanca
Dissertations, Theses, and Capstone Projects
Early life adversity (ELA) is the exposure to a single or to multiple traumatic events before the age of 18 that go beyond the child’s coping. These adverse events are often exacerbated during adolescence particularly when cognitive performance is compromised. Adolescents who experienced ELA may show symptoms of post-traumatic stress disorder (PTSD), while not vividly recalling the early life trauma. These individuals show atypical connectivity between prefrontal-amygdala and hippocampus, all of which is associated with an increased risk of experiencing a traumatic event again later in life. While clinical research has increasingly stressed the importance in addressing the long-lasting consequences …
The Feeling Mind, Maria Doulatova
The Feeling Mind, Maria Doulatova
Arts & Sciences Electronic Theses and Dissertations
According to standard conceptions of agency, our reasons and intentions guide our actions. That is, goal-directed intentions play a key role in practical deliberation, planning, and execution of action. Furthermore, purposeful, goal-directed behavior warrants attributions of responsibility or “reactive attitudes” like resentment, anger, gratitude and forgiveness. However, recent developments of the dual-process theory of mind cast doubt on the empirical adequacy of this picture. While people take themselves to be responding to relevant reasons, they are often bypassed by irrelevant affective or automatic reactions. In this work I go beyond the dual-process theory of mind to offer a mechanistic account …
Mental Imagery In The Regulation Of Differential Fear Conditioning: A Multimodal Investigation Involving Self-Report, Psychophysiology, And Brain Imaging, Tyler Daniel Robinson
Mental Imagery In The Regulation Of Differential Fear Conditioning: A Multimodal Investigation Involving Self-Report, Psychophysiology, And Brain Imaging, Tyler Daniel Robinson
LSU Doctoral Dissertations
Mental imagery is a common component in a range of emotion regulation techniques. However, the effectiveness and neural mechanisms of regulation via mental imagery are underexplored due to a lack of studies targeting mental imagery specifically. This discrepancy results in uncertainty regarding the mechanism of regulation in existing paradigms. Biased competition for attentional resources presents a plausible model by which a mental imagery-based distracter can downregulate response to an emotional stimulus. If visualizing an imagined distracter effectively regulates emotional response, the inclusion of mental imagery components in other techniques represents a potential confound. To address this discrepancy, this dissertation investigates …
Open Vs. Closed Skill Acute Exercise On Emotional Memory, Ashley Lovorn
Open Vs. Closed Skill Acute Exercise On Emotional Memory, Ashley Lovorn
Honors Theses
ABSTRACT ASHLEY LOVORN: Acute Open vs. Closed Skill Exercise on Emotional Memory (Under the direction of Dr. Paul D. Loprinzi)
Accumulating research suggests that acute exercise may influence emotional memory. However, there is limited research on this topic evaluating which modality of exercise elicits the greatest effects on emotional memory. The purpose of this thesis experiment was to evaluate if treadmill exercise (closed-skill) has a differential impact on emotional memory relative to racquetball exercise (open-skill). One-hundred and ninety- three participants were recruited and divided into three groups: closed-skill (N=65), open- skill (N=65) and control (N=64). Prior to exercise, each of …
Improving Stimulus Realism: The Effect Of Visual Dimension On Affective Responding, Shannon Compton
Improving Stimulus Realism: The Effect Of Visual Dimension On Affective Responding, Shannon Compton
Electronic Thesis and Dissertation Repository
For decades researchers have used 2D stimuli under the assumption that they accurately represent real objects. This assumption has been challenged by recent vision and neuroeconomics research which has found that 2D images can evoke different neural and behavioural responses than real objects. The current study continues this line of research in the field of affective cognitive neuroscience; a field where small effect sizes are common and rapid habituation to affective stimuli used in the lab often occurs. The present study uses realistic 2D and 3D emotional images to determine the impact of visual dimension on affective responding. Subjective ratings …
Influences Of Autism Spectrum Disorder On Sensory And Emotional Responses To Smell And Taste Cues, Asmita Singh
Influences Of Autism Spectrum Disorder On Sensory And Emotional Responses To Smell And Taste Cues, Asmita Singh
Graduate Theses and Dissertations
Autism spectrum disorder (ASD) is a developmental disability that causes social, communication, behavioral and sensory challenges. The prevalence has been on a rise, with the latest reports stating 1 in 59 children is diagnosed with ASD. These challenges play a significant role in feeding behavior, leading to reduced nutrition among individuals. Much research in this field has been attributed to children, however, this study was focused on the adult population, in an attempt to improve their quality of life. Building on previous findings and knowledge gaps, the objectives of this thesis were two-fold: To better understand the sensory experiences of …
Cannabis-Using Youth Demonstrated Blunted Rostral Anterior Cingulate Cortex Activation, But Normal Functional Connectivity, During An Emotional Go/No-Go Task, Kristin Elizabeth Maple
Cannabis-Using Youth Demonstrated Blunted Rostral Anterior Cingulate Cortex Activation, But Normal Functional Connectivity, During An Emotional Go/No-Go Task, Kristin Elizabeth Maple
Theses and Dissertations
Cannabis use has been associated with deficits in self-regulation, including inhibitory control. Cannabis users have previously exhibited both structural and functional deficits in the rostral anterior cingulate cortex (rACC), a region involved in self-regulation of emotional response and inhibitory control. The present study aimed to examine whether abstinent cannabis users demonstrated abnormal functional activation and connectivity of the bilateral rACC during an emotional inhibitory processing task, and whether gender moderated these relationships. The study also aimed to examine whether bilateral rACC activation and connectivity in cannabis users was related to perceived stress. It was hypothesized that cannabis users would exhibit …
Hypothalamic Circuits In The Control Of Feeding And Emotional Behaviors, Leandra Mangieri
Hypothalamic Circuits In The Control Of Feeding And Emotional Behaviors, Leandra Mangieri
Dissertations & Theses (Open Access)
Feeding results from the integration of both nutritional and affective states, and is guided by complex neural circuitry in the brain. The hypothalamus is a critical center controlling feeding and motivated behaviors. We found that targeted photostimulation of projections from the lateral hypothalamus (LH) to the paraventricular hypothalamus (PVH) in mice elicited voracious feeding and repetitive self-grooming behavior. GABA neurotransmission in the LH->PVH circuit mediated the evoked feeding behavior, and elicited behavioral approach, whereas glutamate release promoted repetitive self-grooming, which was stress-related in nature. Optogenetic inhibition of LHGABA ->PVH circuit reduced feeding after fasting, whereas photostimulation abruptly …
Development Of A Methodology For Predicting Consumer Acceptance And Preference Toward Beverages, Shilpa Shailesh Samant
Development Of A Methodology For Predicting Consumer Acceptance And Preference Toward Beverages, Shilpa Shailesh Samant
Graduate Theses and Dissertations
Consumer behavior toward food/beverages is influenced by multisensory attribute perceptions as well as emotional experiences. Traditional methods of sensory testing lack the ability to capture emotional responses and as a result, measuring food/beverage-evoked emotions remains a research challenge. There were three objectives of this dissertation study. Firstly, this study aimed to develop prediction models of acceptance of and preference for basic taste solutions using sensory attribute intensities and emotional responses. Secondly, this study aimed to extend the findings of the first objective to develop prediction models of commercially-available vegetable juice products in terms of (a) acceptance and preference under blind-tasting …
Influences Of Intrinsic And Extrinsic Hand-Feel Touch Cues On Sensory Perception And Emotional Responses Toward Beverage Products, Ragita Cantika Pramudya
Influences Of Intrinsic And Extrinsic Hand-Feel Touch Cues On Sensory Perception And Emotional Responses Toward Beverage Products, Ragita Cantika Pramudya
Graduate Theses and Dissertations
Consumer perception of and preference toward products are influenced by intrinsic product-specific (e.g., product temperature) and extrinsic non-product-specific (e.g., packaging or container) characteristics. Besides communicating information between products and consumers to create expectations toward the content at the point of sale, packaging also influences sensory perception of the content during consumption. Previous cross-modal studies on packaging effects on the content had largely overlooked hand-feel touch cues. Touch closely relates to consumers’ emotional responses to and their quality evaluation of products. One way to manipulate hand-feel touch cues in a beverage consumption setting is to vary materials of cup sleeve, which …
Event-Related Potential Studies Of Error Monitoring To Affective And Non-Affective Stimuli In Adolescents And Emerging Adults, Rebecca K. Reed
Event-Related Potential Studies Of Error Monitoring To Affective And Non-Affective Stimuli In Adolescents And Emerging Adults, Rebecca K. Reed
Dissertations, Theses, and Capstone Projects
It is hypothesized that prefrontal cortex (PFC) and anterior cingulate cortex (ACC) function may be still under development in adolescents. As the generator of the error-related negativity (ERN) and the N2, the ACC is expected to be sensitive to the degree of development with age. In adults, these top-down control areas ideally serve to direct attention to goal-relevant information, which can increase the likelihood of making a correct choice, even in fast-response laboratory based tasks. However, adolescents may show increased susceptibility in these top-down control areas when the stimulus is social and emotional. In the first study, event-related potentials were …
Personality In California Sea Lions (Zalophus Californianus) And Harbor Seals (Phoca Vitulina): Methodological Convergence And Species-Specific Emotional Repertoires, Amber De Vere
Dissertations
Despite the wide acceptance of animal personality as a valid area of study, research on marine mammal personality remains remarkably scarce. What literature does exist predominantly focuses on bottlenose dolphins (Frick, 2016; Highfill & Kuczaj, 2007; Kuczaj, Highfill & Byerly, 2012; Lilley, de Vere, Yeatre & Kuczaj, 2018; Moreno, Highfill & Kuczaj, 2017). There is also strong evidence for individual differences in grey seals (Robinson et al., 2015; Twiss & Franklin, 2010; Twiss, Culloch & Pomeroy, 2011; Twiss, Cairns, Culloch, Richards & Pomeroy, 2012), and preliminary research has provided evidence of broad personality factors in pinniped species using behavioral coding …
Assessing The Long-Term Sequelae Of Mild Traumatic Brain Injury, Janna Mantua
Assessing The Long-Term Sequelae Of Mild Traumatic Brain Injury, Janna Mantua
Doctoral Dissertations
A mild traumatic brain injury (mTBI), also known as a concussion, is defined as an injury that results in an alteration of consciousness or mental status. Previous studies have shown mTBI populations experience a number of chronic (> 1 year) symptoms, such as sleep disturbances (e.g., sleep stage alterations), mood alterations (e.g., depressive symptoms), and cognitive alterations (e.g., poor concentration). The three chapters of this dissertation sought to explore these long-term sequelae and the possible interrelations between them. In the first experiment, sleep-dependent memory consolidation of neutral stimuli was probed in a chronic mTBI sample and a control, uninjured sample. …
Preserved Consciousness In The Absence Of A Cerebral Cortex, The Legal And Ethical Implications Of Redefining Consciousness And Its Neural Correlates: A Case For A Subcortical System Generating Affective Consciousness, Shadia Kawkabani
Williams Honors College, Honors Research Projects
Historically, the scientific and medical communities have taken a corticocentric view on consciousness, emphasizing the need for a cortex in producing the conscious experience. The preserved consciousness observed in hydranencephalic children and decorticated rats suggests that some form of consciousness may be produced by a subcortical network. The brainstem, a phylogenetically ancient and conserved brain structure, could serve as the major integrative machinery to produce this form of consciousness, which is called affective consciousness—the evolutionary antecedent to the reflective consciousness that allows humans to reflect on their experiences. The functional convergence of the brainstem with the amygdala, motor system, and …
Consumer Evaluation: The Link Between Body Mass Index, Reward Sensitivity, Product Liking And Emotion, Malori Comer
Consumer Evaluation: The Link Between Body Mass Index, Reward Sensitivity, Product Liking And Emotion, Malori Comer
Master's Theses
The objectives of this study were: (1) to evaluate consumer acceptance of cheeses varying in fat and sodium levels, (2) to determine if sensitivity to reward and body mass index has an effect on product liking based on fat or salt content, (3) to evaluate the use of FaceReader technology during consumer evaluation and, (4) to determine if consumer’s self-selected, conscious emotions matched with the expressed, subconscious emotions acquired by FaceReader.
Consumer acceptance testing (n=108) was conducted on two medium cheddar cheeses with varying fat levels and two low-moisture part-skim mozzarella cheeses varying in sodium levels. Attributes were measured using …
Physiological And Subjective Aspects Of Positive Mood In Relation To Executive Functioning: The Potential Moderating Role Of Personality, Luz Helena Ospina
Physiological And Subjective Aspects Of Positive Mood In Relation To Executive Functioning: The Potential Moderating Role Of Personality, Luz Helena Ospina
Dissertations, Theses, and Capstone Projects
Positive affect has been demonstrated to improve aspects of cognition. However, recent studies reveal that positive affect may hinder the same cognitive processes, such as executive functioning, memory and creativity. These discrepant findings may be due to differing levels of physiological arousal, a component of the circumplex model of affect, which has been largely ignored in affective research. For example, one recent study suggests that positive valence coupled with varying levels of physiological arousal (i.e., low, moderate, and high) may differentially affect performance on tasks of verbal fluency and memory. Furthermore, one other explanation for these inconsistent findings may relate …
The Role Of Estrogen In Emotional And Cognitive Processes Integral To Major Depressive Disorder, Kimberly Albert
The Role Of Estrogen In Emotional And Cognitive Processes Integral To Major Depressive Disorder, Kimberly Albert
Graduate College Dissertations and Theses
Women have greater incidence and prevalence of Major Depressive Disorder (MDD) than men during the reproductive life phase when ovarian hormones fluctuate, suggesting that ovarian hormones have a significant role in MDD etiology in women. As the core symptoms of MDD are indicative of alterations in stress responding, emotional processing, and mood regulation, examining the effects of the estrogen on these processes in women may provide a better understanding of the role of estrogen in the sex difference in MDD rates. The general aim of this dissertation was to examine neural, emotional, and attentional processes related to stress response alterations …
An Intra-Individual Event-Related Potential-Based Concealed Attitude Test, David R. Herring
An Intra-Individual Event-Related Potential-Based Concealed Attitude Test, David R. Herring
Open Access Theses & Dissertations
The evaluative oddball is an implicit measure for detecting (concealed) attitudes. In evaluative oddball studies, low occurrence stimuli such as negative pictures are presented among high occurrence context stimuli such as positive pictures. Late positive potentials (LPPs) of the event-related potential (ERP) are larger to evaluatively incongruent stimuli such as negatives compared to congruent stimuli such as positives with the context (e.g., positives). In prior evaluative oddball paradigms, this evaluative congruity effect of the LPP was reduced when participants concealed compared to truthfully reported attitudes. Because prior evaluative oddballs have been focused on the group level analysis, it has been …
Cultivating The Compass: Examining The Role Of Emotional Appraisal And Professional Agency Among Stakeholders In Kentucky Agricultural Education, Savannah Faye Robin
Cultivating The Compass: Examining The Role Of Emotional Appraisal And Professional Agency Among Stakeholders In Kentucky Agricultural Education, Savannah Faye Robin
Theses and Dissertations--Community & Leadership Development
Agricultural Education has been informed by four major areas including agricultural education (teaching and learning), educational policy, agricultural policy (industry collaboration) and research. Historically agriculture teachers have been removed from the policy process affecting their profession in these four areas (Thompson, 1963). A review of historical literature suggests that only twice have teachers been involved in the policy process. The purpose of this study was to examine the involvement levels of stakeholders in agricultural education across the state of Kentucky. Specifically, examining the emotional appraisal of specific issues in agricultural education and if the emotions of stakeholders influence their involvement …
