Controlled Attention And Sleep Deprivation: Adding A Self-Regulation Approach?, June J. Pilcher, Holly A. Geldhauser, J. Adam Beeco, Tracy A. Lindquist Apr 2016

Controlled Attention And Sleep Deprivation: Adding A Self-Regulation Approach?, June J. Pilcher, Holly A. Geldhauser, J. Adam Beeco, Tracy A. Lindquist

June Pilcher

The current study examined performance on an automated task battery under short-term sleep deprivation and non-sleep deprivation conditions. Twenty-six volunteers completed the sleep deprivation study. Twenty-three volunteers completed the non-sleep deprivation study. Performance was examined across five test sessions during 25 hours of acute sleep deprivation conditions and during two days of non-sleep deprivation conditions. ANOVAs examining changes in performance from baseline levels indicated that performance under sleep deprivation conditions resulted in a decrease in performance in some tasks and an increase in estimated blood alcohol concentration. Non-sleep deprivation resulted in stable or increasing performance and a decrease in estimated …


Explaining The Longitudinal Association Between Puberty And Depression: Sex Differences In The Mediating Effects Of Peer Stress, Colleen Conley, Karen Rudolph, Fred Bryant Dec 2015

Explaining The Longitudinal Association Between Puberty And Depression: Sex Differences In The Mediating Effects Of Peer Stress, Colleen Conley, Karen Rudolph, Fred Bryant

Colleen S. Conley

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 …

Social Motivation Is Associated With Elevated Salivary Cortisol In Boys With An Asd, Vicki Bitsika, Christopher Sharpley, Linda Agnew, Nicholas Andronicos Nov 2015

Social Motivation Is Associated With Elevated Salivary Cortisol In Boys With An Asd, Vicki Bitsika, Christopher Sharpley, Linda Agnew, Nicholas Andronicos

Vicki Bitsika

Because social communication difficulties and stress are common in children with an ASD, and because it has been hypothesised that the two are related, the association between these two variables was investigated in a sample of 90 boys with an ASD and who were aged between 6 years and 12 years of age. The Social Responsiveness Scale (SRS) was completed by the parents of these boys about their sons, plus salivary cortisol samples were collected from the boys. Results indicated that only one aspect of the boys' SRS was significantly correlated with cortisol—Social Motivation (SM). Factor analyses revealed two discrete …


Coping Styles, Opioid Blockade, And Cardiovascular Response To Stress, Stephen Bruehl, James Mccubbin, John Wilson, Thomas Montgomery, Paloma Ibarra, Charles Carlson Jul 2014

Coping Styles, Opioid Blockade, And Cardiovascular Response To Stress, Stephen Bruehl, James Mccubbin, John Wilson, Thomas Montgomery, Paloma Ibarra, Charles Carlson

James A. McCubbin

We investigated the hypothesis that the effects of Monitoring and Blunting coping styles are mediated in part by endogenous opioids. Mean arterial pressure (MAP) and heart rate (HR) were measured in 39 males before, during, and after a mental arithmetic stressor. Each subject experienced the protocol once under opioid blockade (naltrexone) and once in a placebo condition, in counterbalanced order. Monitoring and Blunting were assessed using the Miller Behavioral Style Scale. High Blunting and high Monitoring were both associated with poorer MAP recovery under opioid blockade than in the placebo condition. Similar effects were noted for Blunting on the measure …


Relaxation Training And Opioid Inhibition Of Blood Pressure Response To Stress, James Mccubbin, John Wilson, Stephen Bruehl, Paloma Ibarra, Charles Carlson, Jane Norton, George Colclough Jul 2014

Relaxation Training And Opioid Inhibition Of Blood Pressure Response To Stress, James Mccubbin, John Wilson, Stephen Bruehl, Paloma Ibarra, Charles Carlson, Jane Norton, George Colclough

James A. McCubbin

The present study was designed to determine the role of endogenous opioid mechanisms in the circulatory effects of relaxation training. Opioid mechanisms were assessed by examination of the effects of opioid receptor blockade with naltrexone on acute cardiovascular reactivity to laboratory stress before and after relaxation training. 32 young men with mildly elevated casual arterial pressure were recruited for placebo-controlled naltrexone stress tests and relaxation training. The results indicated that relaxation training significantly reduced the diastolic pressure response to mental arithmetic stress. Opioid receptor blockade with naltrexone antagonized the effects of relaxation training. These findings suggest that some of the …


Individual Differences In Rat Locomotor Activity Are Diminished By Nicotine Through Stimulation Of Central Nicotinic Acetylcholine Receptors, Rick A. Bevins, Joyce Besheer May 2012

Individual Differences In Rat Locomotor Activity Are Diminished By Nicotine Through Stimulation Of Central Nicotinic Acetylcholine Receptors, Rick A. Bevins, Joyce Besheer

Rick A. Bevins

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 Mar 2012

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. …

Charles A. Sanislow, Ph.D.

Objective:  Although much attention has been given to the effects of adverse childhood experiences on the development of personality disorders (PDs), we know far less about how recent life events influence the ongoing course of functioning. We examined the extent to which PD subjects differ in rates of life events and the extent to which life events impact psychosocial functioning. Method:  A total of 633 subjects were drawn from the Collaborative Longitudinal Personality Disorders Study (CLPS), a multi-site study of four personality disorders – schizotypal (STPD), borderline (BPD), avoidant (AVPD), obsessive-compulsive (OCPD) – and a comparison group of major depressive …
