Autonomic And Behavioral Reactivity To An Acute Laboratory Stressor, Jeremy C. Peres
Autonomic And Behavioral Reactivity To An Acute Laboratory Stressor, Jeremy C. Peres
University of New Orleans Theses and Dissertations
Stress has been widely shown to directly influence people’s emotional and behavioral processing as well as their underlying biological systems. This project examined physiological and behavioral responses as indicators of stress and coping in the context of a psychosocial stressor in a controlled laboratory setting. We examined the association between indicators of behavioral coping and underlying physiological reactivity within participants while experiencing stress. Participants included 68 emerging adults. Physiological measures include autonomic biomarkers (e.g., heart-rate, skin conductance) at rest and during the stressor while behavioral indicators that were coded include acute verbal and non-verbal actions exhibited by participants during the …

The study was to examine 1) whether stress and coping styles could significantly predict the probability of suicide ideation; 2) and whether coping styles were mediators or moderators on the association between life stress and suicide ideation. The survey was conducted in a sample of 671 Chinese college students. Approximately twenty percent students reported having suicide ideation. Life stress, active coping styles, and passive coping styles all had independent effect on the probability of suicide ideation. Passive coping styles, especially fantasizing, mediated the relation between life stress and suicide ideation. Moderation hypotheses were not supported. Implications of the findings and …
The Effects Of Stress On Delay Discounting Performance For Higher And Lower Intelligence Individuals, Rebecca Brodoff
The Effects Of Stress On Delay Discounting Performance For Higher And Lower Intelligence Individuals, Rebecca Brodoff
Honors Theses
Maintaining self-control can be a draining and arduous task, which may be affected by several external factors, such as stress or IQ level. An experiment was conducted on the effects of induced stress on Delay Discounting (DD) performance, or a measure of self-control, and the extent to which IQ level moderated this effect. Participants recorded their SAT or ACT scores (which were later converted to IQ scores), were exposed to a stress-inducing or control task requiring them to place their arms in ice-cold or luke-warm water, respectively, and then completed a DD task where they made a number of hypothetical …
Individual Differences In Rat Locomotor Activity Are Diminished By Nicotine Through Stimulation Of Central Nicotinic Acetylcholine Receptors, Rick A. Bevins, Joyce Besheer
Individual Differences In Rat Locomotor Activity Are Diminished By Nicotine Through Stimulation Of Central Nicotinic Acetylcholine Receptors, Rick A. Bevins, Joyce Besheer

An increasing body of research has focused on isolating factors that predict or alter individual differences in the behavioral and neural processes mediating the effects of abused drugs. Within this framework, the current report assessed individual differences and the locomotor effect of nicotine. Rats were screened for activity induced by a novel environment. Rats, which were more active to initial environment exposure, remained more active even after seven additional 30-min exposures to the same environment. Treatment with nicotine-di-D tartrate (1 mg/kg, sc) disrupted this effect. This nicotine disruption of individual differences occurred whether nicotine suppressed locomotor activity (initial administration) or …
Anger, Child Behavior, And Family Distress: Further Evaluation Of The Parental Anger Inventory, Georganna Sedlar, David J. Hansen
Anger, Child Behavior, And Family Distress: Further Evaluation Of The Parental Anger Inventory, Georganna Sedlar, David J. Hansen
David J. Hansen
Presumably, anger is a common experience of parenting. Although practitioners and researchers recognize the role of anger in various parenting situations, objective and standardized measures of parental anger have been notably lacking in the field. This study examined the Parental Anger Inventory (PAI), a measure developed specifically to assess parental anger in response to child misbehavior. A diverse sample of 98 parents participated in the study, including (a) physically abusive or neglectful parents, or both, n = 44; (b) nonmaltreating clinic parents seeking assistance for child behavior problems, n = 24; and (c) nonmaltreating, non–help-seeking community parents, n = 30. …
The Effects Of Adolescent Binge Drinking On Corticotropin-Releasing Factor Cells In The Amygdala And Social Predictors Of Alcohol Intake In Male And Female Rats, Chrisanthi Karanikas
The Effects Of Adolescent Binge Drinking On Corticotropin-Releasing Factor Cells In The Amygdala And Social Predictors Of Alcohol Intake In Male And Female Rats, Chrisanthi Karanikas
Masters Theses 1911 - February 2014
Alcohol is one of the most common drugs of choice among adolescents. Normally, the method of consumption is drinking large quantities of alcohol in short periods of time, otherwise known as “binge drinking.” Corticotropin releasing factor (CRF) stress peptide producing cells in central nucleus of the amygdala (CeA) has been implicated in behavioral responses to stress and addiction. The goals of this thesis were to determine the effects of voluntary binge drinking in adolescence and vapor-induced alcohol dependence in adulthood on CRF cells in the CeA. These studies were done using an operant model of voluntary binge drinking in rodents …

This research investigated whether exposure to peer stress serves as one pathway through which pubertal development contributes to depression over time, differentially for girls and boys. Youth (N = 149; 9.6–14.8 years) and their caregivers provided information at two waves, 1 year apart, on puberty (Wave 1), peer stress (occurring between Waves 1 and 2), and depression (Waves 1 and 2). Structural equation modeling analyses examined sex differences in the extent to which peer stress mediated the impact of pubertal status and timing on subsequent depression (i.e., tests of moderated mediation). Significant sex-moderated mediation was found for both pubertal status …
The Impact Of A Naturalistic Stressor On Spontaneous Alternation Behavior: A New Animal Model Of Ocd, Christina Finch
The Impact Of A Naturalistic Stressor On Spontaneous Alternation Behavior: A New Animal Model Of Ocd, Christina Finch
Behavioral Neuroscience Honors Papers
Over the past few decades, various animal models of obsessive compulsive disorder (OCD) have been developed. Similarly, various stressors have been used throughout animal research. The Spontaneous Alternation Behavioral (SAB) model is a well-established model of OCD while 2,5-dihydro-2,4,5-trimethylthiazoline (TMT) has recently become a popular naturalistic stressor. This study linked the two together, thus modeling the effect of stress on OCD behaviors. After living in an enriched or standard environment for 3 weeks, male Sprague-Dawley rats were exposed to either TMT or no odor, and then were examined in the SAB task. Unlike what was hypothesized, the enriched environment proved …
A Qualitative Study Of Mothers Who Work Full-Time As Hospital Floor Nurses, Michael W. Firmin, Megan Bailey Pathammavong
A Qualitative Study Of Mothers Who Work Full-Time As Hospital Floor Nurses, Michael W. Firmin, Megan Bailey Pathammavong
Psychology Faculty Publications
We conducted qualitative interviews with a sample of 13 female floor nurses in a Midwest hospital. The women worked full-time and also had children at home for whom they provided care. The overall four results reported include particular challenges they faced in their dual-roles, including separating home from work, high stress, sleep deprivation, odd hours, and difficulty in advancing due to home life pressures. The nurses also related perceived assets and drawbacks of their profession for the given season of life. They described what they believed to be necessities for success in the dual-roles of professional nurse and care taker. …
