Oxytocin Attenuates Yohimbine-Induced Reinstatement Of Alcohol-Seeking In Female Rats Via The Central Amygdala, Samantha M. Wilfur, Elizabeth C. Mcneely, Aliya A. Lackan, Cassie P. Bowers, Kah-Chung Leong

Psychology Faculty Research

Alcohol use disorder is a significant public health concern, further exacerbated by an increased risk of relapse due to stress. In addition, factors such as biological sex may contribute to the progression of addiction, as females are especially susceptible to stress-induced relapse. While there have been many studies surrounding potential pharmacological interventions for male stress-induced ethanol reinstatement, research regarding females is scarce. Recently, the neuropeptide oxytocin has gained interest as a possible pharmacological intervention for relapse. The present study examines how oxytocin affects yohimbine-induced reinstatement of ethanol-seeking in female rats using a self-administration paradigm. Adult female rats were trained to …

Pandemic Upon Pandemic: Middle-Aged And Older Men Who Have Sex With Men Living With Hiv Coping And Thriving During The Peak Of Covid-19, Sherry Bell, Brandon Ranuschio, John M. Waldron, Lianne Barnes, Nadia Sheik-Yosef, Esmeralda Villalobos, Janelle Wackens, Renato M. Liboro

Psychology Faculty Research

When the COVID-19 pandemic emerged in early 2020, not only did it abruptly impede the progress that was being made toward achieving global targets to end the HIV pandemic, but it also created significant impacts on the physical and mental health of middle-aged and older men who have sex with men living with HIV. Utilizing a qualitative, community-based participatory research approach, we conducted semi-structured, one-on-one interviews with 16 ethnoracially diverse, middle-aged and older men who have sex with men living with HIV residing in Southern Nevada, to examine the different ways the COVID-19 pandemic directly impacted their physical and mental …

Stuck In The Past? Rumination-Related Memory Integration, Paula T. Hertel, C. Wahlheim, William A. Price, Emily M. Crusius, Christina L. Patino

Psychology Faculty Research

Memories connected to ruminative concerns repetitively capture attention, even in situations designed to alter them. However, recent research on memory updating suggests that memory for benign substitutes (e.g., reinterpretations) might be facilitated by integration with the ruminative memories. As a first approach, two experiments (Ns = 72) mimicked rumination-related memories with rumination-themed stimuli and an imagery task. College undergraduates screened for ruminative status first studied and imaged ruminative cue-target word pairs, and then in a second phase they studied the same cues re-paired with benign targets (along with new and repeated pairs). On the test of cued recall of …

Sport And Mental Health Performance Optimization In An Adolescent Gymnast: A Case Evaluation, Davy Phrathep, Brad C. Donohue, Brenna N. Renn, John Mercer Dr., Daniel N. Allen

Psychology Faculty Research

The Optimum Performance Program in Sports (TOPPS) is a multi-component, sport-specific Family Behavior Therapy that has demonstrated improved sport performance, relationships, and mental health outcomes in adult and adolescent athletes with, and without, diagnosed mental health disorders in clinical trials. The current case trial demonstrates successful implementation of a novel component of TOPPS (i.e., talk aloud optimal sport performance imagery leading to dream mapping) in a biracial Latina and White adolescent gymnast without a mental health diagnosis. The participant demonstrated significant improvements from baseline to both post-treatment and 3-month follow-up in severity of mental health functioning, factors interfering with sports …

Adaptation In The Sensory Cortex Drives Bistable Switching During Auditory Stream Segregation, Nathan C. Higgins, Alexandra N. Scurry, Fang Jiang, David F. Little, Mounya Elhilali, Joel S. Snyder

Psychology Faculty Research

Current theories of perception emphasize the role of neural adaptation, inhibitory competition, and noise as key components that lead to switches in perception. Supporting evidence comes from neurophysiological findings of specific neural signatures in modality-specific and supramodal brain areas that appear to be critical to switches in perception. We used functional magnetic resonance imaging to study brain activity around the time of switches in perception while participants listened to a bistable auditory stream segregation stimulus, which can be heard as one integrated stream of tones or two segregated streams of tones. The auditory thalamus showed more activity around the time …

Attitudes, Clinical Practices, And Perceived Advocacy Needs Of Professionals With Interests In Personality Disorders, William D. Ellison, S. Huprich, A. Behn, M. Goodman, S. Kerr, K. N. Levy, S. M. Nelson, C. Sharp, The Board Of Directors Of The International Society For The Study Of Personality Disorders

Psychology Faculty Research

Experts in personality disorders (PDs) generally prefer dimensional diagnostic systems to categorical ones, but less is known about experts’ attitudes toward personality pathology diagnoses in adolescents, and little is known about public health shortfalls and advocacy needs and how these might differ geographically. To fill these gaps, the International Society for the Study of Personality Disorders surveyed 248 professionals with interests in PDs about their attitudes toward different diagnostic systems for adults and adolescents, their PD-related clinical practices, and perceived advocacy needs in their area. Results suggested that dimensional diagnostic systems are preferable to categorical and that skepticism about personality …

The Registration Continuum In Personality Disorder Studies: Theory, Rationale, And Template, Stephen D. Benning, Edward A. Smith

Psychology Faculty Research

Registration is a tool to increase the rigor of personality disorder research and its ability to reduce human suffering through improving people's lives. This article details the problems that exist without registrations, which revolve around a study's outcomes' dependence on the data rather than on the theory being tested. Registrations exist on a continuum underpinned by bipolar timing and unipolar disclosure dimensions, the latter of which poses myriad points of decisions for researchers to register. The registration process provides memory aids and guideposts for researchers through the course of a study, transparently maintains public trust in the scientific enterprise, and …

Myelin Characteristics Of The Corpus Callosum In Capuchin Monkeys (Sapajus [Cebus] Apella) Across The Lifespan, Chase M. Watson, Chet C. Sherwood, Kimberley A. Phillips

Psychology Faculty Research

The midsagittal area of the corpus callosum (CC) is frequently studied in relation to brain development, connectivity, and function. Here we quantify myelin characteristics from electron microscopy to understand more fully differential patterns of white matter development occurring within the CC. We subdivided midsagittal regions of the CC into: I—rostrum and genu, II—rostral body, III—anterior midbody, IV—posterior midbody, and V—isthmus and splenium. The sample represented capuchin monkeys ranging in age from 2 weeks to 35 years (Sapajus [Cebus] apella, n = 8). Measurements of myelin thickness, myelin fraction, and g-ratio were obtained in a systematic random …

Paired Housing Or A Socially-Paired Context Decreases Ethanol Conditioned Place Preference In Male Rats, Eva Lorenz, Chase Moye, Kah-Chung Leong

Psychology Faculty Research

Alcohol abuse dramatically affects individuals’ lives nationwide. The 2020 National Survey on Drug Use and Health (NSDUH) estimated that 10.2% of Americans suffer from alcohol use disorder. Although social support has been shown to aid in general addiction prevention and rehabilitation, the benefits of social support are not entirely understood. The present study sought to compare the benefits of social interaction on the conditioned ethanol approach behavior in rats through a conditioned place preference (CPP) paradigm in which a drug is paired with one of two distinct contexts. In experiment 1A, rats were single-housed and received conditioning trials in which …

A Behavioral Economic Demand Analysis Of Media Multitasking In The College Classroom: A Cluster Analysis, Masahiro Toyama, Yusuke Hayashi

Psychology Faculty Research

Media multitasking has brought concerns (e.g., lower productivity and performance) in multiple settings including college classrooms. The present study examined the behavior of texting in the classroom (TIC) by applying the behavioral economic demand theory while taking college students’ different attitudes and behaviors of TIC into consideration. Undergraduate students (109 females and 73 males for valid data, whose average age was 19.4 [SD = 2.5]) completed questionnaires on demographic characteristics, TIC-related attitude and behavior, and a demand task with a hypothetical scenario, which aimed to quantify the value of social rewards from text messaging with demand intensity (i.e., excessiveness) …

Longitudinal Associations Between Personal Growth And Cognitive Functioning In Adulthood, Masahiro Toyama

Psychology Faculty Research

Objectives: While personal growth has been found to be associated with multiple aspects of health in adulthood, its associations with cognitive functioning have not been fully understood. The present study aimed to assess both directions of such longitudinal associations.

Method: Using data from the second wave (Time 1 [T1]) and third wave (Time 2 [T2]) of the Midlife in the United States (MIDUS) study (N = 4,206; mean age = 56.0 [standard deviation (SD) = 12.3]), a longitudinal measurement model containing latent variables of episodic memory and executive function was first constructed. Built on the measurement model, a …

Auditory Affective Processing, Musicality, And The Development Of Misophonic Reactions, Solena Mednicoff, Sivan Barashy, Destiny Gonzales, Stephen D. Benning, Joel S. Snyder, Erin Hannon

Psychology Faculty Research

Misophonia can be characterized both as a condition and as a negative affective experience. Misophonia is described as feeling irritation or disgust in response to hearing certain sounds, such as eating, drinking, gulping, and breathing. Although the earliest misophonic experiences are often described as occurring during childhood, relatively little is known about the developmental pathways that lead to individual variation in these experiences. This literature review discusses evidence of misophonic reactions during childhood and explores the possibility that early heightened sensitivities to both positive and negative sounds, such as to music, might indicate a vulnerability for misophonia and misophonic reactions. …

Longitudinal Associations Of Perceived Mastery And Constraints With Coping And Their Implications For Functional Health For Aging Adults, Masahiro Toyama, Joel M. Hektner

Psychology Faculty Research

The present study examined longitudinal associations of distinct dimensions of perceived control (i.e., perceived mastery and constraints) with approach and avoidance coping relating to functional health for aging adults, which had not been well studied previously. Using data from two waves of Midlife in the United States (N = 4,963, whose mean age was 55.4 [SD = 12.5]), a longitudinal path model was analyzed for direct and indirect effects among perceived mastery and constraints, approach and avoidance coping, and functional limitations. Bidirectional associations were observed between perceived mastery and approach coping and between perceived constraints and avoidance coping. …

Recently Integrated Alu Elements In Capuchin Monkeys: A Resource For Cebus/Sapajus Genomics, J. M. Storer, J. A. Walker, C. E. Rockwell, G. Mores, T. O. Beckstrom, J. D. Orkin, A. D. Melin, Kimberley A. Phillips, C. Roos, M. A. Batzer

Psychology Faculty Research

Capuchins are platyrrhines (monkeys found in the Americas) within the Cebidae fam-ily. For most of their taxonomic history, the two main morphological types of capuchins, gracile (untufted) and robust (tufted), were assigned to a single genus, Cebus. Further, all tufted capuchins were assigned to a single species, Cebus apella, despite broad geographic ranges spanning Central and northern South America. In 2012, tufted capuchins were assigned to their genus, Sapajus, with eight currently recognized species and five Cebus species, although these numbers are still under debate. Alu retrotransposons are a class of mobile element insertion (MEI) widely used …

Preschool Children’S Processing Of Events During Verb Learning: Is The Focus On People (Faces) Or Their Actions (Hands)?, Jane B. Childers, Emily Grace Warkentin, Blaire M. Porter, Marissa Young, Sneh Lalani, Akila Gopalkrishnan

Psychology Faculty Research

Verbs are central to the syntactic structure of sentences, and, thus, important for learning one’s native language. This study examined how children visually inspect events as they hear, and do not hear, a new verb. Specifically, there is evidence that children may focus on the agent of the action or may prioritize attention to the action being performed; to date, little evidence is available. This study used an eye tracker to track 2-, 3-, and 4-year-olds’ looking to the agent (i.e., face) vs. action (i.e., hands) while viewing events linked to a new verb as well as distractor events. A …

Longitudinal Implications Of Social Integration For Age And Gender Differences In Late-Life Physical Functioning, Masahiro Toyama, Heather R. Fuller, Jonix Owino

Psychology Faculty Research

Social integration has documented benefits for late-life health; yet, little is known about its impacts on trajectories of physical functioning. This study examines age and gender differences in the longitudinal associations between social integration and activities of daily living (ADLs) using a hierarchical linear model with three waves of survey data collected over 4 years from the Social Integration and Aging Study (N = 400; baseline mean age = 80.3). Findings indicated some interaction effects of age, gender, and/or social integration on ADL trajectories. Among those of more advanced age, women showed greater increases in ADL limitations than men, …

Longitudinal And Age-Related Implications Of Primary And Secondary Control For Hedonic And Eudaimonic Well-Being, Masahiro Toyama

Psychology Faculty Research

The longitudinal associations of primary and secondary control with two distinct aspects of happiness including hedonic/subjective and eudaimonic/psychological well-being had not been fully studied. The present study aimed to contribute to the literature by examining these associations and their age differences. Using data from the second and third waves of the Midlife in the United States (MIDUS; N = 4963, aged 28 to 84 at baseline), the present study conducted structural equation modeling analyses to examine whether one primary control strategy (persistence in goal striving) and two secondary control strategies (positive reappraisals and lowering aspirations) predicted residualized changes in the …

Inferences Training Affects Memory, Rumination, And Mood, B. Perlman, N. Mor, Y. Wisney Jacobinski, A. Doron Zakon, N. Avirbach, Paula T. Hertel

Psychology Faculty Research

Making negative inferences for negative events, ruminating about them, and retrieving negative aspects of memories have all been associated with depression. However, the causal mechanisms that link negative inferences to negative mood and the interplay between inferences, rumination, and memory have not been explored. In the current study, we used a cognitive-bias modification (CBM) procedure to train causal inferences and assessed training effects on ruminative thinking, memory, and negative mood among people with varying levels of depression. Training had immediate effects on negative mood and rumination but not after recall of a negative autobiographical memory. Note that training affected memory: …

Challenging Depressive Beliefs: Habitual And Recollective Components Of Stability Or Change, Paula T. Hertel, M. C. Acuff, J. Hernandez, E. Poppe

Psychology Faculty Research

Background and objectives. Depressed people tend to hold stable negative beliefs that resist challenges. Two experiments investigated the cognitive bases of belief change or resistance to change following the provision of supportive or challenging pseudo-evidence.

Method. Students scoring high and low on a measure of depressed state read belief statements, each followed by invented experimental evidence to either verify or discount them. Two days later, they read all the belief statements again, together with new statements, this time rating belief.

Results. The students agreed that the statements described common beliefs and that the evidence was plausible. Discounted statements were believed …

Perception Of Narcissism In College Professors, Harry M. Wallace, A. Carrillo, Jack Kelley

Psychology Faculty Research

We conducted three studies to examine perceptions of grandiose narcissism in college professors. Narcissism might appear incompatible with the profession if professors are viewed fundamentally as helpers or as introverted bookworms. Then again, people might expect professors to display big egos congruent with the prestige of their profession and their privileged public platforms. Our research indicates that professors are generally not seen as highly narcissistic according to the criteria of the Narcissistic Personality Inventory and the Narcissistic Admiration and Rivalry Questionnaire, though they are viewed as more narcissistic than elementary school teachers. More professor narcissism was expected at colleges that …

Longitudinal Associations Of Conscientiousness And Neuroticism With Perceived Mastery And Constraints For Aging Adults, Masahiro Toyama, Heather R. Fuller, Joel M. Hektner

Psychology Faculty Research

It has not been well understood how conscientiousness and neuroticism are associated with two related but distinct dimensions of perceived control (i.e., perceived mastery and constraints) among aging adults. The present study examined these associations and their change over time, while addressing whether they differ by age or gender. For respondents aged 50+ at baseline (N = 2,768) in the Midlife in the United States (MIDUS) study, multilevel modeling analyses were conducted to assess how conscientiousness and neuroticism predicted perceived mastery and constraints over 2 decades. As expected, higher conscientiousness and lower neuroticism (for both between- and within-person variability) predicted …

Common Features In Compulsive Sexual Behavior, Substance Use Disorders, Personality, Temperament And Attachment—A Narrative Review, Yaniv Efrati, Shane W. Kraus, Gal Kaplan

Psychology Faculty Research

Do addictions share common traits of an “addictive personality” or do different addictions have distinct personality profiles? This narrative review examines the differences in the associations between substance use disorder (SUD) and compulsive sexual behavior disorder (CSBD), on the one hand, and personality traits, attachment dispositions, and temperament, on the other hand. We found that both people with a SUD and people with CSBD tended to be more spontaneous, careless, and less reliable, to place self-interest above getting along with others, to show emotional instability and experience negative emotions such as anger, anxiety, and/or depression, to be less able to …

Awareness And Knowledge Of Aging And Hiv-Associated Neurocognitive Disorder: Service User And Provider Perspectives And Experiences In Southern Nevada, Renato M.

This community report presents the findings and analysis of a survey that was part of the quantitative stage of a mixed-method Community-Based Participatory Research (CBPR) project dedicated to examine the awareness and knowledge of racially and ethnically diverse, middle-aged and older people living with HIV/AIDS, and their healthcare and service providers from Southern Nevada, on aging, brain health, HIV/AIDS, and the condition known as HIV-Associated Neurocognitive Disorder. The CBPR project was conducted in collaboration with community partners such as the LGBTQIA+ Community Center of Southern Nevada, Southern Nevada Health District’s Ryan White Program, Community Counseling Center of Southern Nevada, and …

Community-Level Resources Bolstering Resilience To Hiv/Aids: Perspectives Of Middle-Aged And Older Men Who Have Sex With Men Living With Hiv/Aids, Renato M. Liboro, Tammy C. Yates, Charles Fehr, George Da Silva, Francisco Ibañez-Carrasco, Andrew Eaton, Daniel Pugh, Lori E. Ross, Paul A. Shuper

Psychology Faculty Research

Most prior research on resilience to HIV/AIDS has utilized quantitative tools (e.g., scales and surveys) to examine individual-level assets (e.g., self-efficacy, hope, optimism) that researchers believe represent or approximate resilience to HIV/AIDS with minimal consideration for the perspectives of men who have sex with men (MSM), the population that has remained at greatest risk of, and the most impacted by HIV/AIDS in North America since the 1980s. The aim of this qualitative study is to identify community-level resources that bolster resilience to HIV/AIDS based specifically on the perspectives and lived experiences of middle-aged and older (MAO) MSM living with HIV/AIDS. …

Oxytocin Attenuates The Stress-Induced Reinstatement Of Alcohol-Seeking In Male Rats: Role Of The Central Amygdala, Hannah S. Ballas, Samantha M. Wilfur, Nicole A. Freker, Kah-Chung Leong

Psychology Faculty Research

Factors such as stress and anxiety often contribute to alcohol-dependent behavior and can trigger a relapse of alcohol addiction and use. Therefore, it is important to investigate potential pharmacological interventions that may alleviate the influence of stress on addiction-related behaviors. Previous studies have demonstrated that the neuropeptide oxytocin has promising anxiolytic potential in mammals and may offer a pharmacological target to diminish the emotional impact on reinstatement of alcohol-seeking. The purpose of the present study was to investigate the effect of oxytocin on stress-induced alcohol relapse and identify a neural structure mediating this effect through the use of an ethanol …

Development And Initial Validation Of A Scale To Measure Momentary Self-Concept Clarity, William D. Ellison, Juyoung Yun, Margaret I. Lupo, Autumn K. Lucas-Marinelli, Victoria B. Marshall, Arielle Faith R. Matic, Alec C. Trahan

Psychology Faculty Research

Several studies have suggested that momentary self-concept clarity (SCC) levels are important for emotion regulation and self-control processes, but these studies have used unvalidated measures of momentary SCC. Here, we report on the development and preliminary validation of a brief self-report scale, the Momentary Self-Concept Clarity Scale (M-SCCS). One hundred and twenty-two adults completed momentary SCC items 6-7 times per day for two weeks. Multilevel factor analyses suggested the M-SCCS has good factorial validity. The scale also showed excellent between-person reliability, fair within-person reliability, and patterns of criterion relations that resemble other self-report measures of SCC. There was little measurement …

Artificial Intelligence: An Interprofessional Perspective On Implications For Geriatric Mental Health Research And Care, Brenna N. Renn, Matthew Schurr, Oleg Zaslavsky, Abhishek Pratap

Psychology Faculty Research

Artificial intelligence (AI) in healthcare aims to learn patterns in large multimodal datasets within and across individuals. These patterns may either improve understanding of current clinical status or predict a future outcome. AI holds the potential to revolutionize geriatric mental health care and research by supporting diagnosis, treatment, and clinical decision-making. However, much of this momentum is driven by data and computer scientists and engineers and runs the risk of being disconnected from pragmatic issues in clinical practice. This interprofessional perspective bridges the experiences of clinical scientists and data science. We provide a brief overview of AI with the main …

Behavioral Context Affects Social Signal Representations Within Single Primate Prefrontal Cortex Neurons, Vladimir Jovanovic, Adam R. Fishbein, Lisa A. De La Mothe, Kuo-Fen Lee, Cory T. Miller

Psychology Faculty Research

We tested whether social signal processing in more traditional, head-restrained contexts is representative of the putative natural analog – social communication – by comparing responses to vocalizations within individual neurons in marmoset prefrontal cortex (PFC) across a series of behavioral contexts ranging from traditional to naturalistic. Although vocalization responsive neurons were evident in all contexts, cross-context consistency was notably limited. A response to these social signals when subjects were head-restrained was not predictive of a comparable neural response to the identical vocalizations during natural communication, even within the same neuron. Neural activity at the population level followed a similar pattern, …

The Assessment Of Physical Risk Taking: Preliminary Construct Validation Of A New Behavioral Measure, Edward A. Smith, Stephen D. Benning

Psychology Faculty Research

Risk taking is a complex heterogeneous construct that has proven difficult to assess, especially when using behavioral tasks. We present an exploratory investigation of new measure–the Assessment of Physical Risk Taking (APRT). APRT produces a variety of different outcome scores and is designed as a comprehensive assessment of the probability of success and failure, and magnitude of reward and punishment of different types of simulated physically risky behaviors. Effects observed on the simulated behaviors are hypothesized to reflect similar effects on real world physical risks. Participants (N = 224) completed APRT in a laboratory setting, half of whom had a …
