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 …

Neural Basis Of The Potentiated Inhibition Of Repeated Haloperidol And Clozapine Treatment On The Phencyclidine-Induced Hyperlocomotion, Changjiu Zhao, Tao Sun, Ming Li

Department of Psychology: Faculty Publications

Clinical observations suggest that antipsychotic effect starts early and increases progressively over time. This time course of antipsychotic effect can be captured in a rat phencyclidine (PCP)-induced hyperlocomotion model, as repeated antipsychotic treatment progressively increases its inhibition of the repeated PCP-induced hyperlocomotion. Although the neural basis of acute antipsychotic action has been studied extensively, the system that mediates the potentiated effect of repeated antipsychotic treatment has not been elucidated. In the present study, we investigated the neuroanatomical basis of the potentiated action of haloperidol (HAL) and clozapine (CLZ) treatment in the repeated PCP-induced hyperlocomotion. Once daily for five consecutive days, …

Sleep Hygiene And Problem Behaviors In Snoring And Non- Snoring School-Age Children, Lisa A. Witcher, David Gozal, Dennis L. Molfese, Scott M. Salathe, Karen Spruyt, Valerie Mclaughlin Crabtree

Center for Brain, Biology, and Behavior: Faculty and Staff Publications

Objectives—The effects of sleep-disordered breathing, sleep restriction, dyssomnias, and parasomnias on daytime behavior in children have been previously assessed. However, the potential relationship(s) between sleep hygiene and children’s daytime behavior remain to be explored. The primary goal of this study was to investigate the relationship between sleep hygiene and problematic behaviors in non-snoring and habitually snoring children.

Methods—Parents of 100 5- to 8-year-old children who were reported to snore “frequently” to “almost always,” and of 71 age-, gender-, and ethnicity-matched children who were reported to never snore participated in this study. As part of a larger, ongoing study, …

Making A Large Class Feel Small Using Social Psychology: Introducing Teams To Improve Performance And Learning In A Large-Enrollment Course, Bethany Johnson

Department of Psychology: Dissertations, Theses, and Student Research

Large-enrollment lecture-based classes are increasingly common in higher education. As an alternative approach, active learning methods are meant to develop academic skills and improve understanding of course content. Group work is an effective form of active learning, but students typically despise it. Social psychological small group theory can inform teachers about the characteristics of small groups that influence their capability to improve learning, so that teachers can design more effectual group work for their classes. This study examined what effect introducing permanent teams into a large enrollment class had on students’ sense of classroom community and their learning outcomes, using …

A Test Of A Conceptual Model Of Sexual Self-Concept And Its Relation To Other Dimensions Of Sexuality, Arielle R. Deutsch

Department of Psychology: Dissertations, Theses, and Student Research

One theoretical concept that has received modest attention in contemporary sexuality research is the sexual self, particularly focusing on sexual self-concept (SSC). While research on the sexual self has expanded over the past 20 years, there is a lack of cohesion within this research that has culminated in a collection of SSC models that, while sharing certain factors, are dissimilar from each other. Therefore a unified conceptual model of SSC needs to be empirically established. Additionally, little research has examined potential differences between genders in how SSC is expressed, as most SSC research focuses exclusively on women. Finally, understanding of …

Psychotherapy Clients’ Online Behavior And Opinions Regarding Internet Searches Conducted By Therapists, Emily B. Gale

Department of Psychology: Dissertations, Theses, and Student Research

The Internet has become possibly the most popular medium to find information and communicate in our society. For the field of psychology, the Internet offers a new way to collect data and communicate with both study participants and, for practicing psychologists, possibly clients. Little is known, however, about the implications of interacting with clients online. The existing empirical studies in this area (DiLillo & Gale, 2011; Lehavot, Barnett, & Powers, 2010; Taylor et al., 2010) have focused on psychology graduate students’ actions online. These studies highlight the importance and paucity of research regarding the online behaviors of psychotherapy clients and …

Communication-Based Assessment Of Developmental Age For Young Children With Developmental Disabilities, Shari L. Deveney, Lesa Hoffman, Cynthia J. Cress

Department of Psychology: Faculty Publications

Purpose: In this study, the authors compared a multiple-domain strategy for assessing developmental age of young children with developmental disabilities who were at risk for long-term reliance on augmentative and alternative communication (AAC) with a communication-based strategy composed of receptive language and communication indices that may be less affected by physically challenging tasks than traditional developmental age scores.

Method: Participants were 42 children (age 9–27 months) with developmental disabilities and who were at risk for long-term reliance on AAC. Children were assessed longitudinally in their homes at 3 occasions over 18 months using multiple-domain and communication-based measures. Confirmatory factor analysis …

Linking Outcomes From Peabody Picture Vocabulary Test Forms Using Item Response Models, Lesa Hoffman, Jonathan Templin, Mabel L. Rice

Department of Psychology: Faculty Publications

Purpose: The present work describes how vocabulary ability as assessed by 3 different forms of the Peabody Picture Vocabulary Test (PPVT; Dunn & Dunn, 1997) can be placed on a common latent metric through item response theory (IRT) modeling, by which valid comparisons of ability between samples or over time can then be made.

Method: Responses from 2,625 cases in a longitudinal study of 697 persons for 459 unique PPVT items (175 items from Peabody Picture Vocabulary Test—Revised [PPVT–R] Form M [Dunn & Dunn, 1981], 201 items from Peabody Picture Vocabulary Test—3 [PPVT–3] Form A [Dunn & Dunn, 1997], and …

Stress, Coping And Suicide Ideation In Chinese College Students, Xiaoyun Zhang, Haiping Wang, Yan Ruth Xia, Xiaohong Liu, Eunju Jung

Department of Child, Youth, and Family Studies: Faculty Publications

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 Role Of Engagement Across Conceptually Distinct Treatment Elements For Social Anxiety Disorder, Timothy M. Emge

Department of Psychology: Dissertations, Theses, and Student Research

There are currently several efficacious treatments for social anxiety disorder (e.g. exposure therapy and cognitive therapy). Each of these treatments is thought to reduce symptoms of social anxiety by disrupting maintenance mechanisms of the disorder, yet mechanism of change research has not supported this view. The current study compared components from each therapy modality in order to better understand why symptoms reduce similarly between conceptually distinct treatments. Participants with high social anxiety were randomly assigned to give a speech with cognitive restructuring and engagement-enhancing procedures, cognitive preparation and video feedback, or a speech alone. Self-ratings of speech performance, confidence in …

Dimensions Of Individuals' Judgements About Sexual Attraction, Romantic Attachment, And Sexual Orientation, Luis F. Morales Knight

Department of Psychology: Dissertations, Theses, and Student Research

Despite 150 years of scientific interest in sexual orientation, contemporary investigators grapple with a number of serious difficulties. A precise, unified definition of sexual orientation appropriate for scientific use continues to elude researchers, most likely because there is still no single coherent theory of sexual orientation. This lack impedes research into the measurement of sexual orientation. Existing measurements of sexual orientation rely on partial or incompletely empirical research. The present study identified promising avenues for development of credible definitions, theories, and measurements of sexual orientation: (a) mate-selection tasks; (b) the idea that bisexually-identified individuals place a lower priority on partner …

Love Means Never Having To Say You're Sorry, But What About Malpractice? A Look At Verbal And Nonverbal Factors Affecting Perceptions Of Apologies In A Medical Malpractice Case, Sarah Thimsen

Department of Psychology: Dissertations, Theses, and Student Research

Apologies are part of daily life and occur in a variety of contexts. A large body of literature on the effects of apologies indicated that apologies have a positive effect – those receiving apologies have more positive views of the transgressor (e.g., Bornstein, Rung, & Miller, 2002; Goei, Roberty, Meyer, & Carlyle, 1997; Robbennolt, 2003; Sitkin & Beis, 1993; Takaku, 2000). An area of emerging research in the realm of apologies is in the area of medical malpractice. The research presented here sought to expand on the field of apologies, specifically by examining the effects of an apology in a …

Adolescent Decision Making And Risk Behavior: A Neurobiological Approach, Jennifer M. Wolff

Department of Psychology: Dissertations, Theses, and Student Research

In this study, the neurobiological theory of adolescent decision making and risk taking and the dual-process decision making theory were tested in a sample of college students. Participants responded to questions in a survey about decision making style, socio-emotional processes, cognitive control processes, and deviant peers. The goals of the research were to test the relation between decision making processes (intuitive and deliberative) and risk behaviors, to test the potential overlap between intuitive and deliberative decision making as described in the more traditional dual-process models and the socio-emotional and cognitive control systems of the neurobiological model, and to extend the …

Methamphetamine-Associated Psychosis, Kathleen M. Grant, Tricia D. Le Van, Sandra M. Wells, Ming Li, Scott F. Stoltenberg, Howard E. Gendelman, Gustavo Carlo, Rick A. Bevins

Department of Psychology: Faculty Publications

Methamphetamine (METH) is a frequent drug of abuse in U.S. populations and commonly associated with psychosis. This may be a factor in frequent criminal justice referrals and lengthy treatment required by METH users. Persecutory delusions and auditory hallucinations are the most consistent symptoms of METH-associated psychosis (MAP). MAP has largely been studied in Asian populations and risk factors have varied across studies. Duration, frequency and amount of use as well as sexual abuse, family history, other substance use, and co-occurring personality and mood disorders are risk factors for MAP. MAP may be unique with its long duration of psychosis and …

Motivation & Loss Aversion In The Health Savings Account Paradigm, Michael Holtje

Department of Psychology: Dissertations, Theses, and Student Research

This investigation examined the role of “loss aversion” and consumers’ motivational orientations in the context of healthcare purchasing under the individual account paradigm and the defined benefit (insurance) paradigm. Specifically, this dissertation investigated (1) whether Health Savings Accounts (HSAs) encourage more prudent health care spending compared to traditional health insurance plans and (2) the impact of individuals' motivational preferences (either towards “gains” or towards “losses”) between decision tasks under each type of health plan.

Three experiments varied the type of healthcare plan that consumers had and the manner in which they received information (either as a “gain” or “loss”). The …

Latino Adolescent Adjustment: An Examination Of Cultural Values, Maria I. Iturbide

Department of Psychology: Dissertations, Theses, and Student Research

In the U.S., 22% of children under the age of 18 are Latino and 52% of Latino children have at least one parent who is foreign-born (Fry & Passel, 2009). Latinos are likely to experience acculturative strains associated with a range of negative outcomes such as academic underachievement. A mixed method sequential explanatory design was used to examine the protective effects of cultural factors that may ameliorate the negative effects of acculturative strains on psychological and academic adjustment.

The quantitative phase of the study examined whether biculturalism and ethnic identity would reduce the negative influence of acculturation strains on adjustment …

Anthropological Data Regarding The Adaptiveness Of Hebephilia, Raymond B. Hames, Ray Blanchard

Department of Anthropology: Faculty Publications

Hebephilia is the sexual attraction to early pubertal children in Tanner Stages 2 and 3, generally ages 11 through 14.

The second author of this letter (R.B.), a member of the Paraphilias Subworkgroup of the Work Group on Sexual and Gender Identity Disorders for DSM-5, proposed a diagnostic entity for DSM-5 that resembles the ICD-10 model, but with a different name: Pedohebephilic Disorder. In the original proposal (Blanchard, 2010a), this disorder would have three subtypes: pedophilic, hebephilic, and pedohebephilic. In the current version of the proposal, which is still under consideration, the name has been changed to Pedophilic Disorder, in …

Gender, Gender Roles, And Anxiety: Perceived Confirmability Of Self Report, Behavioral Avoidance, And Physiological Reactivity, Milena Stoyanova, Debra Anne Hope

Department of Psychology: Faculty Publications

Despite the well-documented gender effect in anxiety, less is known about contributing factors to women’s greater risk for anxiety and fears. The present study examined the relationship between gender, gender role orientation (i.e., expressivity/instrumentality) and fear of harmless insects (tarantula), using a multimodal approach of self-report measures, a Behavioral Approach Test (BAT), and physiological reactivity. Participants (144 college students; 67 women, 77 men) completed a questionnaire packet and then were instructed to approach a tarantula. We were unable to replicate Pierce and Kirkpatrick’s (1992) findings that men underreport anxiety. Consistent with the literature, women in the study experienced greater anxiety …

Differential Effects Of Acute Amphetamine And Phencyclidine Treatment And Withdrawal From Repeated Amphetamine Or Phencyclidine Treatment On Social Interaction And Social Memory In Rats, Ming Li, Wei He, Rebecca Munro

Department of Psychology: Faculty Publications

Although animal models based on amphetamine (AMPH) or phencyclidine (PCP) treatment have been used extensively to study the neurobiological and behavioral characteristics of schizophrenia, there are conflicting reports regarding their validity in modeling the negative symptoms and cognitive deficits of schizophrenia. The present study examined how acute AMPH or PCP treatment (Experiment 1) and withdrawal from repeated AMPH treatment (Experiment 2) or PCP treatment (Experiment 3) affects social behavior and social recognition memory in male Sprague-Dawley rats. Each subject was tested on two consecutive days. On the first day, the rats were tested four times (5 min/each) at 10-min intervals …

Integrating Sexual Objectification With Object Versus Person Recognition: The Sexualized-Body-Inversion Hypothesis, Philippe Bernard, Sarah J. Gervais, Jill Allen, Sophie Campomizzi, Olivier Klein

Department of Psychology: Faculty Publications

In the study reported here, we tested the novel sexualized-body-inversion hypothesis. Integrating research and theory on objectification and person versus object recognition, we examined whether sexualized women, but not sexualized men, are recognized in the same way as objects are. According to objectification theory (Fredrickson & Roberts, 1997), female bodies are scrutinized and evaluated to a greater degree than male bodies are, which leads to sexual objectification of women. Defined as viewing or treating an individual as a sexualized body, or as sexualized body parts, available for satisfying the needs and desires of other people (Bartky, 1990), sexual objectification has …

Contextual And Behavioral Control Of Antipsychotic Sensitization Induced By Haloperidol And Olanzapine, Chen Zhang, Ming Li

Department of Psychology: Faculty Publications

Repeated administration of haloperidol (HAL) and olanzapine (OLZ) causes a progressively enhanced disruption of the conditioned avoidance response (CAR) and a progressively enhanced inhibition of phencyclidine (PCP)-induced hyperlocomotion in rats (termed antipsychotic sensitization). Both actions are thought to reflect intrinsic antipsychotic activity. The present study examined the extent to which antipsychotic- induced sensitization in one model (e.g. CAR) can be transferred or maintained in another (e.g. PCP hyperlocomotion) as a means of investigating the contextual and behavioral controls of antipsychotic sensitization. Well-trained male Sprague-Dawley rats were first repeatedly tested in the CAR or the PCP (3.2 mg/kg, subcutaneously) hyperlocomotion model …

Intertemporal Choice In Lemurs, Jeffrey R. Stevens, Nelly Mühlhoff

Department of Psychology: Faculty Publications

Different species vary in their ability to wait for delayed rewards in intertemporal choice tasks. Models of rate maximization account for part of this variation, but other factors such as social structure and feeding ecology seem to underly some species differences. Though studies have evaluated intertemporal choice in several primate species, including Old World monkeys, New World monkeys, and apes, prosimians have not been tested. This study investigated intertemporal choices in three species of lemur (black-and- white ruffed lemurs, Varecia variegata, red ruffed lemurs, Varecia rubra, and black lemurs, Eulemur macaco) to assess how they compare to …

Clozapine, But Not Olanzapine, Disrupts Conditioned Avoidance Response In Rats By Antagonizing 5-Ht2a/2c Receptors, Ming Li, Tao Sun, Alexa Mead

Department of Psychology: Faculty Publications

The present study was designed to assess the role of 5-HT_2A/2C receptors in the acute and repeated effect of clozapine and olanzapine in a rat conditioned avoidance response model, a validated model of antipsychotic activity. Male Sprague–Dawley rats that were previously treated with either phencyclidine (0.5–2.0 mg/kg, sc), amphetamine (1.25–5.0 mg/kg, sc), or saline and tested in a prepulse inhibition of acoustic startle study were used. They were first trained to acquire avoidance response to a white noise (CS1) and a pure tone (CS2) that differed in their ability to predict the occurrence of footshock. Those who acquired avoidance …

Confirmatory Factor Analysis Of The Preschool Behavioral And Emotional Rating Scale (Prebers) With Preschool Children With Disabilities, Cynthia J. Cress, Lori Synhorst, Michael Epstein, Elizabeth Allen

Department of Psychology: Faculty Publications

The Preschool Behavioral and Emotional Rating Scale (PreBERS) is a standardized, norm-referenced instrument that assesses emotional and behavioral strengths of preschool children. This study investigated whether the PreBERS four-factor structure (i.e., emotional regulation, school readiness, social confidence, and family involvement) could be replicated with an early childhood special education (ECSE) sample of children. Teachers who participated in the study rated a total of 1,103 preschool children with disabilities. Confirmatory factor analysis determined the extent to which the ECSE data fit the original four-factor PreBERS structure identified with the national normative sample. Results indicated that the four-factor structure demonstrated an acceptable …
