The Psychosocial Beliefs, Experiences And Expectations Of Children Living With Obesity, Lisa Newson, Nicola Sides, Amineh Rashidi

Research outputs 2022 to 2026

Background: Childhood obesity has been shown to impair psychological health. However, psychological factors are often overlooked in both research evaluations and treatment interventions, and children's perspectives on managing obesity are underexplored. Neglecting psychosocial factors might undermine interventions. This research explored the psychological beliefs, expectations and experiences of children living with obesity (range 7–13) and attending a weight management programme (WMP). Methods: Thirty-four participants (19 females, 15 males, average age 9.5 years) completed a semistructured interview. Recorded interviews were transcribed verbatim and analysed using thematic analysis. Results: Four overarching themes were developed: (1) defining health and self-recognition; (2) external influence; feedback, …

Psychological And Psychosocial Effects Of Contemplative Practices In The Athletic Population: A Systematic Review, Victoria Baker

West Chester University Master’s Theses

Mental health concerns in athletes are becoming a primary focus for institutions, companies, coaches, and more. An athlete carries an abundant load of stressors due to their lifestyle. The stressors can negatively impact an athlete by producing anxiety, depression, insomnia, and other mental health issues. Previous studies have found a connection between the use of contemplative practices on psychological and psychosocial effects in athletes, creating an opportunity to evaluate the research of contemplative practices in the athletic population. A systematic review was conducted using nine electronic databases. Seven studies were included in this review, each assessing how contemplative practices affect …

Pediatric Asthma And Psychological Resilience: Examining Whether Family Functioning And Social Support Relate To Asthma Symptoms And Lung Function, Dalia Jaafar, Natasha H. Hikita, Pornchai Tirakitsoontorn, Azucena Talamantes, Anchalee Yuengsrigul, Eric Sternlicht, Brooke N. Jenkins

Student Scholar Symposium Abstracts and Posters

Upwards of 6 million children in the United States are afflicted with pediatric asthma. While previous research has linked asthma to multiple contributing biological and environmental factors, recent research suggests that psychological and social factors may have an impact on physiological outcomes of asthma like lung function and lung inflammation. Therefore, we suggest the need to study the impact of positive psychological factors such as a well-functioning family environment and beneficial social support on symptoms and lung function of children diagnosed with asthma. In the present pilot study, we recruited a total of 15 children with a confirmed asthma diagnosis …

Response inhibition is essential for navigating everyday life. Its derailment is considered integral to numerous neurological and psychiatric disorders, and more generally, to a wide range of behavioral and health problems. Response-inhibition efficiency furthermore correlates with treatment outcome in some of these conditions. The stop-signal task is an essential tool to determine how quickly response inhibition is implemented. Despite its apparent simplicity, there are many features (ranging from task design to data analysis) that vary across studies in ways that can easily compromise the validity of the obtained results. Our goal is to facilitate a more accurate use of the …

The Effects Of Stress Mindset Interventions On University Students' Health And Functioning, Abigail Fate

Undergraduate Honors Papers

In modern society, the overwhelming cultural narrative proclaims that stress is detrimental to health and should be limited and avoided at all costs. However, recent research has demonstrated that it is one’s stress mindset, rather than their stress level, that determines the psychological and physiological outcomes. Mindsets are lenses that simplify and order the world, and have been proven to influence daily behavioral and physiological responses to create cascading effects. Recent research has demonstrated that one’s mindset about stress is the demining factor in health, performance, and productivity in response to stressful conditions, and that these mindsets can be manipulated …

The Cognitive And Contextual Underpinnings Of Food Cravings : A Multi-Method Exploration, Martha Niemiec

Legacy Theses & Dissertations (2009 - 2024)

The notion of addiction pervades Western vernacular. While firmly established in the substance and drug literature, the concept of addiction is now increasingly associated with other ingested substances (coffee, chocolate, highly processed foods) and a range of compulsive behaviors (gambling, sex, online social networking, gaming). Addiction is associated with substantial morbidity and mortality, and a greater understanding of its etiology has significant public health implications. The physiological mechanisms thought to contribute to the development and maintenance of addiction (tolerance, withdrawal, and, possibly, craving) are widely considered hallmark features and primary treatment targets, while psychological and contextual factors are often underappreciated …

Older Adults' Health Care Utilization A Year After Experiencing Fear Or Distress From Hurricane Sandy, Laura P Sands, Yimeng Xie, Rachel Pruchno, Allison Heid, Yili Hong

Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship

OBJECTIVE: To determine whether self-reports of disaster-related psychological distress predict older adults' health care utilization during the year after Hurricane Sandy, which hit New Jersey on October 29, 2012.

METHODS: Respondents were from the ORANJ BOWL Study, a random-digit dialed sample from New Jersey recruited from 2006 to 2008. Medicare hospital, emergency department (ED) and outpatient claims data from 2012 and 2013 were matched to 1607 people age 65 and older in 2012 who responded to follow-up surveys conducted from July 2013 to July 2015 to determine their hurricane-related experiences.

RESULTS: In total, 7% (107) of respondents reported they experienced …

Stasi Brainwashing In The Gdr 1957 - 1990, Jacob H. Solbrig, Jacob Hagen Solbrig

University of New Orleans Theses and Dissertations

This thesis examines the methods used by the Ministerium für Staatssicherheit (MfS), more commonly known as the Stasi, or East German secret police, for extraction of information from citizens of the German Democratic Republic for the purpose of espionage and covert operations inside East Germany, as it pertains to the deliberate brainwashing of East German citizens. As one of the most efficient intelligence agencies to ever exist, the Stasi’s main purpose was to monitor the population, gather intelligence, and collect or turn informants. They used brainwashing techniques to control the people of the GDR, keeping the populace paralyzed with fear …

Sleep-Based Memory Processing Facilitates Grammatical Generalization: Evidence From Targeted Memory Reactivation., Laura J Batterink, Ken A Paller

Brain and Mind Institute Researchers' Publications

Generalization-the ability to abstract regularities from specific examples and apply them to novel instances-is an essential component of language acquisition. Generalization not only depends on exposure to input during wake, but may also improve offline during sleep. Here we examined whether targeted memory reactivation during sleep can influence grammatical generalization. Participants gradually acquired the grammatical rules of an artificial language through an interactive learning procedure. Then, phrases from the language (experimental group) or stimuli from an unrelated task (control group) were covertly presented during an afternoon nap. Compared to control participants, participants re-exposed to the language during sleep showed larger …

The Serotonin Transporter Promoter Polymorphism Moderates The Continuity Of Behavioral Inhibition In Early Childhood., Victoria C Johnson, Katie R Kryski, Haroon I Sheikh, Heather J Smith, Shiva M Singh, Elizabeth P Hayden

Brain and Mind Institute Researchers' Publications

Persistently elevated behavioral inhibition (BI) in children is a marker of vulnerability to psychopathology. However, little research has considered the joint influences of caregiver and child factors that may moderate the continuity of BI in early childhood, particularly genetic variants that may serve as markers of biological plasticity, such as the serotonin transporter linked polymorphic region (5-HTTLPR). We explored this issue in 371 preschoolers and their caregivers, examining whether parent characteristics (i.e., overinvolvement or anxiety disorder) and child 5-HTTLPR influenced the continuity of BI between ages 3 and 5. Measures were observational ratings of child BI, observational and questionnaire measures …

Revising The Bis/Bas Scale To Study Development: Measurement Invariance And Normative Effects Of Age And Sex From Childhood Through Adulthood., David Pagliaccio, Katherine R Luking, Andrey P Anokhin, Ian H Gotlib, Elizabeth P Hayden, Thomas M Olino, Chun-Zi Peng, Greg Hajcak, Deanna M Barch

Brain and Mind Institute Researchers' Publications

Carver and White's (1994) Behavioral Inhibition System/Behavioral Activation System (BIS/BAS) Scales have been useful tools for studying individual differences in reward-punishment sensitivity; however, their factor structure and invariance across development have not been well tested. In the current study, we examined the factor structure of the BIS/BAS Scales across 5 age groups: 6- to 10-year-old children (N = 229), 11- to 13-year-old early adolescents (N = 311), 14- to 16-year-old late adolescents (N = 353), 18- to 22-year-old young adults (N = 844), and 30- to 45-year-old adults (N = 471). Given poor fit of the standard 4-factor model (BIS, …

Marriage and Family Therapy Faculty Articles and Research

BACKGROUND Similarly to women, men suffer from engaging in fertility treatments, both physically and psychologically. Although there is a vast body of evidence on the emotional adjustment of women to infertility, there are no systematic reviews focusing on men's psychological adaptation to infertility and related treatments.

OBJECTIVE AND RATIONALE The main research questions addressed in this review were ‘Does male psychological adaptation to unsuccessful medically assisted reproduction (MAR) treatment vary over time?’ and ‘Which psychosocial variables act as protective or risk factors for psychological maladaptation?’

SEARCH METHODS A literature search was conducted from inception to September 2015 on five databases …

Examining The Psychological Adjustments Of Neurotypical Siblings Of Individuals With Autism Spectrum Disorder (Asd) And Determining The Efficiency Of Support Groups, Swathi Deo Sambatha

Undergraduate Research Posters

Neurotypical siblings of individuals with behavioral disorders are reported to have complex, complicated psychological adjustments that vary significantly due to a multitude of sociodemographic factors. In addition, these children are at risk of mental health disorders and negative psychological symptoms. Support groups or extensive social support are known to increase intra-communication and create better sibling dynamics between the neurotypical and autistic siblings. This paper investigates such complications to the psychological adjustment of neurotypical siblings of individuals with autism spectrum disorder (ASD) and determines the implications of the utilization of support groups/social support. The analyzed trends and reportings of multiple studies …

Impact Of Stigma On Attitudes Towards Seeking Professional Psychological Help For Depression, Anna Marie Dierks

All Graduate Theses, Dissertations, and Other Capstone Projects

Depression is the most common mental illness, affecting almost seven percent of Americans each year. Although mental illness treatment through professional psychological services has been proven to be effective, underutilization of these services is high. Underutilization of seeking help could lead to serious consequences, such as suicide. Suicide is the second leading cause of death among adolescents and young adults aged 15-34 years old and in 2013 the highest rates of suicide were among adults aged 45-64 years old. Stigma has been viewed as a barrier to seeking professional psychological help.

Two age groups were chosen for this research due …

Finding The Engram., Sheena A Josselyn, Stefan Köhler, Paul W Frankland

Brain and Mind Institute Researchers' Publications

Many attempts have been made to localize the physical trace of a memory, or engram, in the brain. However, until recently, engrams have remained largely elusive. In this Review, we develop four defining criteria that enable us to critically assess the recent progress that has been made towards finding the engram. Recent 'capture' studies use novel approaches to tag populations of neurons that are active during memory encoding, thereby allowing these engram-associated neurons to be manipulated at later times. We propose that findings from these capture studies represent considerable progress in allowing us to observe, erase and express the engram.

Attentional Filtering Of Visual Information By Neuronal Ensembles In The Primate Lateral Prefrontal Cortex., Sébastien Tremblay, Florian Pieper, Adam Sachs, Julio Martinez-Trujillo

Brain and Mind Institute Researchers' Publications

The activity of neurons in the primate lateral prefrontal cortex (LPFC) is strongly modulated by visual attention. Such a modulation has mostly been documented by averaging the activity of independently recorded neurons over repeated experimental trials. However, in realistic settings, ensembles of simultaneously active LPFC neurons must generate attentional signals on a single-trial basis, despite the individual and correlated variability of neuronal responses. Whether, under these circumstances, the LPFC can reliably generate attentional signals is unclear. Here, we show that the simultaneous activity of neuronal ensembles in the primate LPFC can be reliably decoded to predict the allocation of attention …

Psychological Wellness And Health-Related Stigma: A Pilot Study Of An Acceptance-Focused Cognitive Behavioural Intervention For People With Lung Cancer, Suzanne K. Chambers, B A. Morris, S Clutton, E Foley, L Giles, P Schofield, D O'Connell, J Dunn

Research outputs 2014 to 2021

People with lung cancer experience health-related stigma that is related to poorer psychosocial and quality of life outcomes. The present Phase 1 study applied mixed methods to test the acceptability of an acceptance-focused cognitive behavioural intervention targeting stigma for this patient group. Fourteen lung cancer patients completed a 6-week Psychological Wellness intervention with pre- and post-test outcome measures of psychological and cancer-specific distress, depression, health-related stigma and quality of life. In-depth interviews applying interpretative phenomenological analysis assessed participants' experiences of the intervention. Moderate to large improvements were observed in psychological (ηp 2=0.182) and cancer-specific distress (ηp 2=0.056); depression (ηp 2=0.621); …

Striatum In Stimulus-Response Learning Via Feedback And In Decision Making., Nole M Hiebert, Andrew Vo, Adam Hampshire, Adrian M Owen, Ken N Seergobin, Penny A Macdonald

Brain and Mind Institute Researchers' Publications

Cognitive deficits are recognized in Parkinson's disease. Understanding cognitive functions mediated by the striatum can clarify some of these impairments and inform treatment strategies. The dorsal striatum, a region impaired in Parkinson's disease, has been implicated in stimulus-response learning. However, most investigations combine acquisition of associations between stimuli, responses, or outcomes (i.e., learning) and expression of learning through response selection and decision enactment, confounding these separate processes. Using neuroimaging, we provide evidence that dorsal striatum does not mediate stimulus-response learning from feedback but rather underlies decision making once associations between stimuli and responses are learned. In the experiment, 11 males …

Continuous Executive Function Disruption Interferes With Application Of An Information Integration Categorization Strategy., Sarah J Miles, Kazunaga Matsuki, John Paul Minda

Brain and Mind Institute Researchers' Publications

Category learning is often characterized as being supported by two separate learning systems. A verbal system learns rule-defined (RD) categories that can be described using a verbal rule and relies on executive functions (EFs) to learn via hypothesis testing. A nonverbal system learns non-rule-defined (NRD) categories that cannot be described by a verbal rule and uses automatic, procedural learning. The verbal system is dominant in that adults tend to use it during initial learning but may switch to the nonverbal system when the verbal system is unsuccessful. The nonverbal system has traditionally been thought to operate independently of EFs, but …

Effector-Independent Motor Sequence Representations Exist In Extrinsic And Intrinsic Reference Frames., Tobias Wiestler, Sheena Waters-Metenier, Jörn Diedrichsen

Brain and Mind Institute Researchers' Publications

Many daily activities rely on the ability to produce meaningful sequences of movements. Motor sequences can be learned in an effector-specific fashion (such that benefits of training are restricted to the trained hand) or an effector-independent manner (meaning that learning also facilitates performance with the untrained hand). Effector-independent knowledge can be represented in extrinsic/world-centered or in intrinsic/body-centered coordinates. Here, we used functional magnetic resonance imaging (fMRI) and multivoxel pattern analysis to determine the distribution of intrinsic and extrinsic finger sequence representations across the human neocortex. Participants practiced four sequences with one hand for 4 d, and then performed these sequences …

Links Between White Matter Microstructure And Cortisol Reactivity To Stress In Early Childhood: Evidence For Moderation By Parenting., Haroon I Sheikh, Marc F Joanisse, Sarah M Mackrell, Katie R Kryski, Heather J Smith, Shiva M Singh, Elizabeth P Hayden

Brain and Mind Institute Researchers' Publications

Activity of the hypothalamic-pituitary-adrenal axis (measured via cortisol reactivity) may be a biological marker of risk for depression and anxiety, possibly even early in development. However, the structural neural correlates of early cortisol reactivity are not well known, although these would potentially inform broader models of mechanisms of risk, especially if the early environment further shapes these relationships. Therefore, we examined links between white matter architecture and young girls' cortisol reactivity and whether early caregiving moderated these links. We recruited 45 6-year-old girls based on whether they had previously shown high or low cortisol reactivity to a stress task at …

Observing Object Lifting Errors Modulates Cortico-Spinal Excitability And Improves Object Lifting Performance., Gavin Buckingham, Jeremy D Wong, Minnie Tang, Paul L Gribble, Melvyn A Goodale

Brain and Mind Institute Researchers' Publications

Observing the actions of others has been shown to modulate cortico-spinal excitability and affect behaviour. However, the sensorimotor consequences of observing errors are not well understood. Here, participants watched actors lift identically weighted large and small cubes which typically elicit expectation-based fingertip force errors. One group of participants observed the standard overestimation and underestimation-style errors that characterise early lifts with these cubes (Error video--EV). Another group watched the same actors performing the well-adapted error-free lifts that characterise later, well-practiced lifts with these cubes (No error video--NEV). We then examined actual object lifting performance in the subjects who watched the EV …

Rule-Based Category Learning In Children: The Role Of Age And Executive Functioning., Rahel Rabi, John Paul Minda

Brain and Mind Institute Researchers' Publications

Rule-based category learning was examined in 4-11 year-olds and adults. Participants were asked to learn a set of novel perceptual categories in a classification learning task. Categorization performance improved with age, with younger children showing the strongest rule-based deficit relative to older children and adults. Model-based analyses provided insight regarding the type of strategy being used to solve the categorization task, demonstrating that the use of the task appropriate strategy increased with age. When children and adults who identified the correct categorization rule were compared, the performance deficit was no longer evident. Executive functions were also measured. While both working …

Prefrontal Neurons Of Opposite Spatial Preference Display Distinct Target Selection Dynamics., Therese Lennert, Julio C Martinez-Trujillo

Brain and Mind Institute Researchers' Publications

Neurons in the primate dorsolateral prefrontal cortex (dlPFC) of one hemisphere are selective for the location of attended targets in both visual hemifields. Whether dlPFC neurons with selectivity for opposite hemifields directly compete with each other for target selection or instead play distinct roles during the allocation of attention remains unclear. We explored this issue by recording neuronal responses in the right dlPFC of two macaques while they allocated attention to a target in one hemifield and ignored a distracter on the opposite side. Forty-nine percent of the recorded neurons were target location selective. Neurons selective for contralateral targets (58%) …

Perceptual Fluency Can Be Used As A Cue For Categorization Decisions., Sarah J Miles, John Paul Minda

Brain and Mind Institute Researchers' Publications

Learning in the prototype distortion task is thought to involve perceptual learning in which category members experience an enhanced visual response (Ashby & Maddox. Annual Review of Psychology, 56, 149-178, 2005). This response likely leads to more-efficient processing, which in turn may result in a feeling of perceptual fluency for category members. We examined the perceptual-fluency hypothesis by manipulating fluency independently from category membership. We predicted that when perceptual fluency was induced using subliminal priming, this fluency would be misattributed to category membership and would affect categorization decisions. In a prototype distortion task, the participants were more likely to judge …

Distinct Patterns Of Functional And Effective Connectivity Between Perirhinal Cortex And Other Cortical Regions In Recognition Memory And Perceptual Discrimination., Edward B O'Neil, Andrea B Protzner, Cornelia Mccormick, D Adam Mclean, Jordan Poppenk, Anthony D Cate, Stefan Köhler

Brain and Mind Institute Researchers' Publications

Traditionally, the medial temporal lobe (MTL) is thought to be dedicated to declarative memory. Recent evidence challenges this view, suggesting that perirhinal cortex (PrC), which interfaces the MTL with the ventral visual pathway, supports highly integrated object representations in recognition memory and perceptual discrimination. Even with comparable representational demands, perceptual and memory tasks differ in numerous task demands and the subjective experience they evoke. Here, we tested whether such differences are reflected in distinct patterns of connectivity between PrC and other cortical regions, including differential involvement of prefrontal control processes. We examined functional magnetic resonance imaging data for closely matched …
