Autonomic And Behavioral Reactivity To An Acute Laboratory Stressor, Jeremy C. Peres Dec 2012

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 …


When That Tune Runs Through Your Head: A Pet Investigation Of Auditory Imagery For Familiar Melodies, Andrea Halpern, Robert J. Zatorre Aug 2012

When That Tune Runs Through Your Head: A Pet Investigation Of Auditory Imagery For Familiar Melodies, Andrea Halpern, Robert J. Zatorre

Andrea Halpern

The present study used positron emission tomography (PET) to examine the cerebral activity pattern associated with auditory imagery for familiar tunes. Subjects either imagined the continuation of nonverbal tunes cued by their first few notes, listened to a short sequence of notes as a control task, or listened and then reimagined that short sequence. Subtraction of the activation in the control task from that in the real-tune imagery task revealed primarily right-sided activation in frontal and superior temporal regions, plus supplementary motor area (SMA). Isolating retrieval of the real tunes by subtracting activation in the reimagine task from that in …


Implicit Memory For Music In Alzheimer's Disease, Andrea Halpern, Margaret G. O'Connor Aug 2012

Implicit Memory For Music In Alzheimer's Disease, Andrea Halpern, Margaret G. O'Connor

Andrea Halpern

Short, unfamiliar melodies were presented to young and older adults and to Alzheimer's disease (AD) patients in an implicit and an explicit memory task. The explicit task was yes–no recognition, and the implicit task was pleasantness ratings, in which memory was shown by higher ratings for old versus new melodies (the mere exposure effect). Young adults showed retention of the melodies in both tasks. Older adults showed little explicit memory but did show the mere exposure effect. The AD patients showed neither. The authors considered and rejected several artifactual reasons for this null effect in the context of the many …


Memory For The Absolute Pitch Of Familiar Songs, Andrea Halpern Aug 2012

Memory For The Absolute Pitch Of Familiar Songs, Andrea Halpern

Andrea Halpern

Four experiments were conducted to examine the ability of people without "perfect pitch" to retain the absolute pitch offamiliar tunes. In Experiment 1, participants imagined given tunes, and then hummed their first notes four times either between or within sessions. The variability of these productions was very low. Experiment 2 used a recognition paradigm, with results similar to those in Experiment 1 for musicians, but with some additional variability shown for unselected subjects. In Experiment 3, subjects rated the suitability ofvarious pitches to start familiar tunes. Previously given preferred notes were rated high, as were notes three or four semitones …


Parametric Studies Of Antipsychotic-Induced Sensitization In The Conditioned Avoidance Response Model: Roles Of Number Of Drug Exposure, Drug Dose, And Test–Retest Interval, Natashia Swalve, Ming Li Aug 2012

Parametric Studies Of Antipsychotic-Induced Sensitization In The Conditioned Avoidance Response Model: Roles Of Number Of Drug Exposure, Drug Dose, And Test–Retest Interval, Natashia Swalve, Ming Li

Department of Psychology: Faculty Publications

Repeated haloperidol and olanzapine treatment produces an enhanced disruption of avoidance responding, a validated measure of antipsychotic activity. Experimental parameters affecting this sensitization-like effect have not been thoroughly examined. The present study investigated the role of three parameters (number of injections, dose, and interval between initial exposure and challenge) in antipsychotic sensitization in the conditioned avoidance response paradigm. Well-trained Sprague–Dawley rats received different numbers of drug treatment (1–5 days) or different doses of haloperidol (0.025–0.10 mg/kg, subcutaneously) or olanzapine (0.5–2.0 mg/kg, subcutaneously). After certain time intervals (4, 10 or 17 days), they were tested for the expression of haloperidol or …


The Change Program: Comparing An Interactive Versus Prescriptive Telephone-Based Behavioural Intervention On The Psychological And Physiological Profiles Of University Students With Obesity, Erin S. Pearson Jul 2012

The Change Program: Comparing An Interactive Versus Prescriptive Telephone-Based Behavioural Intervention On The Psychological And Physiological Profiles Of University Students With Obesity, Erin S. Pearson

Electronic Thesis and Dissertation Repository

The purpose of the CHANGE (Coaching towards Healthy Actions Naturally through Goal-related Empowerment) Program was to compare the effectiveness of an interactive versus prescriptive 12-week telephone-based behavioural intervention on the psychological and physiological profiles of university students with obesity. Motivational Interviewing administered using Co-Active Life Coaching (MI-via-CALC) and a structured lifestyle treatment following the LEARN (Lifestyle, Exercise, Attitudes, Relationships, Nutrition) Program for Weight Management were examined.

Article 1 provided a methodological account of the CHANGE Program which included a detailed rationale for its development and a comprehensive description of the methods used. Because goal setting has been established as an …


Prospective Investigation Of A Ptsd Personality Typology Among Individuals With Personality Disorders, Meghan E. Mcdevitt-Murphy, M. Tracie Shea, Shirley Yen, Carlos M. Grilo, Charles A. Sanislow, John C. Markowitz, Andrew E. Skodol Jun 2012

Charles A. Sanislow, Ph.D.

This study investigated the replicability of a previously proposed personality typology of posttraumatic stress disorder (PTSD, and explored stability of cluster membership over a 6-month period. Participants with current PTSD (n = 156) were drawn from the Collaborative Longitudinal Personality Disorders Study (CLPS). The CLPS project tracked a large sample of individuals who met criteria for 1 of 4 target diagnoses (borderline, schizotypal, avoidant, and obsessive-compulsive) and a contrast group of individuals who met criteria for depression but no personality disorder. A cluster analysis using scales from the Schedule of Nonadaptive and Adaptive Personality yielded 3 clusters: “internalizing,” “externalizing,” and …


Help-Negation For Suicidal Thoughts In Sub-Clinical Samples Of Young People, Coralie Joy Wilson Jun 2012

Help-Negation For Suicidal Thoughts In Sub-Clinical Samples Of Young People, Coralie Joy Wilson

Coralie J Wilson

Across the popular and academic literature, it is widely recognised that young people with persistent suicidal thoughts are at high risk for suicide completion. It is also accepted that seeking and receiving appropriate help offers protection against the development of acute forms of suicidality, along with suicide completion. Yet, as promising as appropriate help-seeking appears for suicide prevention, a growing number of studies suggest that suicidal ideation itself may impede the help-seeking process. There is evidence that acutely suicidal samples will negate or avoid available help, and there are indications that the help-negation process may occur in samples before levels …


Avoidant Personality Disorder, Traits, And Type, Charles A. Sanislow, Katelin Da Cruz, May O. Gianoli, Elizabeth M. Reagan Mar 2012

Avoidant Personality Disorder, Traits, And Type, Charles A. Sanislow, Katelin Da Cruz, May O. Gianoli, Elizabeth M. Reagan

Charles A. Sanislow, Ph.D.

In this chapter, the evolution of the avoidant personality disorder (AVPD) diagnosis, its current status, and future possibilities are reviewed. AVPD is a chronic and enduring condition involving a poor sense of self and anxiety in social situations, and it is marked by fears of rejection and a distant interpersonal stance. AVPD may be conceptualized at the severe end of a continuum of social anxiety. In the extreme, traits, mechanisms, and symptoms become integral to chronic dysfunction in personality and interpersonal style. While AVPD is a valid diagnostic construct, the optimal organization of AVPD criteria for the diagnosis, and the …

Long-Term Outcomes In Borderline Psychopathology: Old Assumptions, Current Findings, And New Directions, Charles A. Sanislow, Katherine L. Marcus, Elizabeth M. Reagan Jan 2012

Long-Term Outcomes In Borderline Psychopathology: Old Assumptions, Current Findings, And New Directions, Charles A. Sanislow, Katherine L. Marcus, Elizabeth M. Reagan

Charles A. Sanislow, Ph.D.

Borderline personality disorder (BPD) and historical variants of the diagnosis were long held to represent an intractable syndrome of psychopathology consisting of interpersonal, intrapsychic, and affective disturbances. For years, patients labeled “borderline” were regarded pejoratively due at least in part to the lack of effective treatments. Prospective data from recent naturalistic follow-along studies along with the development of treatments with empirically demonstrated efficacy have changed how BPD is viewed. It is now less common to hide the diagnosis from the patient, and BPD has become a useful label to guide the treatment process and help the patient make sense of …


Brief Report: Need For Autonomy And Other Perceived Barriers Relating To Adolescents’ Intentions To Seek Professional Mental Health Care., Coralie J. Wilson, Frank P. Deane Dec 2011

Brief Report: Need For Autonomy And Other Perceived Barriers Relating To Adolescents’ Intentions To Seek Professional Mental Health Care., Coralie J. Wilson, Frank P. Deane

Coralie J Wilson

The current study examined the relationship between belief-based barriers to seeking professional mental health care and help-seeking intentions in a sample of 1037 adolescents. From early adolescence to adulthood, for males and females, the need for autonomy was a strong barrier to seeking professional mental health care. Help-seeking fears were weaker in the older age groups. Having lower perceived need for autonomy and believing that prior mental health care was helpful was significantly associated with higher intentions to seek future professional mental health care. Implications for prevention and overcoming barriers to seeking mental health care are suggested.
