Oxytocin Attenuates Expression, But Not Acquisition, Of Sucrose Conditioned Place Preference In Rats, Devon Patel, Megana Sundar, Eva Lorenz, Kah-Chung Leong

Psychology Faculty Research

Maladaptation of reward processing for natural rewards, such as sucrose or sugar, may play a role in the development of diseases such as obesity and diabetes. Furthermore, uncovering mechanisms to disrupt or reverse maladaptation of reward-seeking behaviors for natural reinforcers can provide insight into treatment of such diseases, as well as disorders such as addiction. As such, studying the effects of potential pharmacotherapeutics on maladaptive sugar-seeking behavior offers valuable clinical significance. Sucrose conditioned place preference (CPP) paradigms can offer insight into aspects of reward processes as it provides a way to assess acquisition and expression of context-reward associations. The present …

For Whom, And For What, Is Experience Sampling More Accurate Than Retrospective Report?, William D. Ellison, Alec C. Trahan, Joseph C. Pinzon, Megan E. Gillespie, Logan M. Simmons, Kendel Y. King

Psychology Faculty Research

The experience sampling method (ESM) is often used in research, and promoted for clinical use, with the rationale that it avoids problematic inaccuracies and biases that attend retrospective measures of mental phenomena. Research suggests that averaged scores from ESM data are more accurate than retrospective ratings. However, it is not known how well individuals can remember information about momentary (rather than averaged) mental states, nor how accurately they estimate the dynamic covariation of these states. Individual differences in retrospective accuracy are also poorly understood. In two pre-registered studies, we examined differences between retrospective memory for stress and self-esteem and data …

Psychotherapy For Borderline Personality Disorder: Does The Type Of Treatment Make A Difference?, William D. Ellison

Psychology Faculty Research

Purpose of Review: The first aim of this review is to summarize the major evidence-based psychotherapies for borderline personality disorder (BPD) and the research supporting their use. The second aim is to explore the evidence for the differential effectiveness of these treatments. Recent Findings: Four types of specific psychotherapies are identified that show promising results in at least two randomized controlled trials. In addition, several adjunctive and minimal/pragmatic interventions are available that are supported by research evidence. Recent findings highlight the applicability of these treatments across settings and populations and have begun to show that modified versions of them are …

Individual Differences And Stability Of Dynamics Among Self-Concept Clarity, Impatience, And Negative Affect, William D. Ellison, Megan E. Gillespie, Alec C. Trahan

Psychology Faculty Research

Self-concept clarity (SCC) is associated with behavioral and emotion regulation, although the nature of this link is unclear. SCC may serve as a self-regulatory resource or it may be a product of well-regulated behaviors and emotions. In two studies using experience sampling among undergraduates (n = 46 and n = 36), we investigate whether models representing relationships among SCC, impatience, and negative affect (NA) states conform to these theories, are similar across individuals, and are stable across a one-month period. Results reveal substantial variation between persons in these dynamic relationships, suggesting that multiple SCC-relevant regulatory processes exist. These patterns …

Dynamics Among Borderline Personality And Anxiety Features In Psychotherapy Outpatients: An Exploration Of Nomothetic And Idiographic Patterns, William D. Ellison, K. N. Levy, M. G. Newman, A. L. Pincus, S. J. Wilson, P. C. M. Molenaar

Psychology Faculty Research

Borderline personality disorder (BPD) involves instability in self-concept, emotions, and behavior. However, the dynamic, longitudinal relations among BPD symptoms and between these symptoms and other problematic emotional experiences are poorly understood. It is also unclear whether these dynamics are the same across persons (including across diagnostic boundaries), specific to individuals with BPD, or idiographic. The current study uses ecological momentary assessment and Group Iterative Multiple Model Estimation (GIMME), a novel, data-driven approach to identifying dynamic patterns in time-series data at group, subgroup, and individual levels, to investigate the dynamic connections among select features of BPD (anger, impulsivity, and identity disturbance) …

Life In A Harsh Environment: The Effects Of Age, Sex, Reproductive Condition, And Season On Hair Cortisol Concentration In A Wild Non-Human Primate, P. A. Garber, A. Mckenney, Evelyn Elizabeth Bartling-John, J. C. Bicca-Marques, M. F. De La Fuente, F. Abreu, N. Schiel, A. Souto, Kimberley A. Phillips

Psychology Faculty Research

Hair cortisol concentration (HCC) provides a long-term retrospective measure of hypothalamic–pituitary–adrenal axis activity, and is increasingly used to assess the life history, health and ecology of wild mammals. Given that sex, age, season and pregnancy influence HCC, and that it may indicate ongoing stress, we examined HCC in common marmosets (Callithrix jacchus) naturally inhabiting a hot and dry semi-desert like habitat, Caatinga, in northeastern Brazil. We trapped, measured, weighed, marked and collected shaved hair from the back of the neck of 61 wild marmosets during the wet and dry seasons. Using enzyme immunoassay, we found that HCC was …

Food Insecurity And Eating Disorders: A Review Of Emerging Evidence, V. M. Hazzard, K. A. Loth, L. Hooper, Carolyn Black Becker

Psychology Faculty Research

Purpose of Review: This review summarizes emerging evidence for the relationship between food insecurity and eating disorder (ED) pathology, outlines priorities for future research in this area, and comments on considerations for clinical and public health practice.

Recent Findings: Among adults, food insecurity is cross-sectionally associated with higher levels of overall ED pathology, binge eating, compensatory behaviors, binge-eating disorder, and bulimia nervosa. Evidence for similar relationships among adolescents has been less robust; however, compared to studies of adults, there have been substantially fewer studies conducted in adolescents to date.

Summary: Emerging evidence consistently indicates that food insecurity …
