Ecological Momentary Assessment Of Anxiety, Daily Stress, And Daily Glycemic Control In Adolescents With Type 1 Diabetes, Natalie Benjamin
Ecological Momentary Assessment Of Anxiety, Daily Stress, And Daily Glycemic Control In Adolescents With Type 1 Diabetes, Natalie Benjamin
Dissertations (1934 -)
Type 1 diabetes (T1D) is an increasingly common chronic illness in children and adolescents that can result in short- and long-term health complications. Adolescents with T1D represent a uniquely vulnerable population, as both physical and psychological disease outcomes tend to deteriorate during this period of development. Thus, among adolescents it is crucial to gain further understanding of what psychological and contextual factors promote optimal disease management. While traditional methods of assessment in this population involve one-time, long-term measurements of psychosocial factors and glycemic control, ecological momentary assessment (EMA), including daily diaries, are increasingly used to capture change processes both between …
Examining The Effects Of Stress And Age On Neural Reward Processing: Considerations For The Role Of Individual Differences In Autonomic Reactivity, William Mccuddy
Examining The Effects Of Stress And Age On Neural Reward Processing: Considerations For The Role Of Individual Differences In Autonomic Reactivity, William Mccuddy
Dissertations (1934 -)
Acute stress is unavoidable and may hinder basic reward processing underlying adaptive decision-making. Additionally, older adults may be at an increased risk of poor decision-making after exposure to acute stress due to age-related changes in cognitive and autonomic functioning. The current study assessed the influence of acute stress, autonomic reactivity, and age on a simple behavioral task during fMRI. Specifically, old and young adults completed a basic reward processing paradigm (i.e., where participants received monetary rewards and punishments) after exposure to acute stress (i.e., social evaluative cold pressor) or control procedure between-subjects. In the young group, differential responses for monetary …

Raising a child with autism spectrum disorder (ASD) poses unique challenges that may impact parents’ mental health and parenting experiences. The current study analyzed self-report data from 77 parents of youth with ASD. A serial multiple mediation model revealed that parenting stress (SIPA) and parental mental health (BAI and BDI-II) appears to be impacted by challenging adolescent behaviors (SSIS-PBs) and, in turn, affect parental involvement (PRQ), controlling for social skills (SSIS-SSs). Further, the study explored the malleability of parents’ mental health over the course of a social skills intervention, and provides modest evidence that parent depressive symptoms decline across intervention. …
Acute Stress Exposure And Expression Of Instrumentally Conditioned Financial Preferences: An Fmri Study, William Travis Mccuddy
Acute Stress Exposure And Expression Of Instrumentally Conditioned Financial Preferences: An Fmri Study, William Travis Mccuddy
Master's Theses (2009 -)
Recent research suggests acute stress exposure is associated with increased habit-based over goal-oriented decision making (e.g., Schwabe & Wolf, 2011). The current study examined whether acute stress promotes the expression of simple financial preferences “overtrained” to the point of habit in the face of a changing environment where said preferences were later rendered non-optimal. Over three days participants (N = 28) learned to discriminate between visual stimuli probabilistically associated with monetary gains or losses and made decisions between stimuli with real financial outcomes. On the fourth day after exposure to either an acute stressor or control procedure participants performed the …
A Neurobiological Pathway That Mediates Stress-Induced Drug Use, Oliver Vranjkovic
A Neurobiological Pathway That Mediates Stress-Induced Drug Use, Oliver Vranjkovic
Dissertations (1934 -)
Cocaine addiction represents a tremendous health and financial burden on our society and the high rate of relapse to cocaine use in abstinent addicts represents a major barrier to effective therapy. Thus, understanding the factors that contribute to relapse and the underlying neurobiological processes is important for guiding the development of treatment for addiction. Stressful life events often trigger drug use in recovering addicts. The contribution of stress to drug use is problematic due to the unpredictable and often uncontrollable nature of stress. A growing literature indicates that norepinephrine and corticotropin releasing factor (CRF) in the brain play key roles …

To expose cortical involvement in age-related changes in motor performance, we compared steadiness (force fluctuations) and fatigability of submaximal isometric contractions with the ankle dorsiflexor muscles in older and young adults and with varying levels of cognitive demand imposed. Sixteen young (20.4 ± 2.1 year: 8 men, 9 women) and 17 older adults (68.8 ± 4.4 years: 9 men, 8 women) attended three sessions and performed a 40 s isometric contraction at 5% maximal voluntary contraction (MVC) force followed by an isometric contraction at 30% MVC until task failure. The cognitive demand required during the submaximal contractions in each session …
An Alternative To The Traditional Cold Pressor Test: The Cold Pressor Arm Wrap, Anthony J. Porcelli
An Alternative To The Traditional Cold Pressor Test: The Cold Pressor Arm Wrap, Anthony J. Porcelli
Psychology Faculty Research and Publications
Recently research on the relationship between stress and cognition, emotion, and behavior has greatly increased. These advances have yielded insights into important questions ranging from the nature of stress' influence on addiction1 to the role of stress in neural changes associated with alterations in decision-making2,3. As topics being examined by the field evolve, however, so too must the methodologies involved. In this article a practical and effective alternative to a classic stress induction technique, the cold pressor test (CPT), is presented: the cold pressor arm wrap (CPAW). CPT typically involves immersion of a participant's dominant hand in ice-cold …

Delay discounting refers to the reduction of the value of a future reward as the delay to that reward increases. The rate at which individuals discount future rewards varies as a function of both individual and contextual differences, and high delay discounting rates have been linked with problematic behaviors, including drug abuse and gambling. The current study investigated the effects of acute anticipatory stress on delay discounting, while considering two important factors: individual perceptions of stress and whether the stressful situation is future-focused or present-focused. Half of the participants experienced acute stress by anticipating giving a videotaped speech. This stress …
Long Term Effects Of Chronic Variable Stress Administered During Different Developmental Stages In Mice, Henry Boeh
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 …
Acute Stress Modulates Risk Taking In Financial Decision Making, Anthony J. Porcelli, Mauricio R. Delgado
Acute Stress Modulates Risk Taking In Financial Decision Making, Anthony J. Porcelli, Mauricio R. Delgado
Psychology Faculty Research and Publications
People’s decisions are often susceptible to various demands exerted by the environment, leading to stressful conditions. Although a goal for researchers is to elucidate stress-coping mechanisms to facilitate decision-making processes, it is important to first understand the interaction between the state created by a stressful environment and how decisions are performed in such environments. The objective of this experiment was to probe the impact of exposure to acute stress on financial decision making and examine the particular influence of stress on decisions with a positive or negative valence. Participants’ choices exhibited a stronger reflection effect when participants were under stress …

We examined the relationship between acute stress and prefrontal-cortex (PFC) based working memory (WM) systems using behavioral (Experiment 1) and functional magnetic resonance imaging (fMRI; Experiment 2) paradigms. Subjects performed a delayed-response item-recognition task, with alternating blocks of high and low WM demand trials. During scanning, participants performed this task under three stress conditions: cold stress (induced by cold-water hand-immersion), a room temperature water control (induced by tepid-water hand-immersion), and no-water control (no hand-immersion). Performance was affected by WM demand, but not stress. Cold stress elicited greater salivary cortisol readings in behavioral subjects, and greater PFC signal change in fMRI …
