The Role Of Psychological Inflexibility And Self-Compassion In Acceptance And Commitment Therapy For Clinical Perfectionism, Clarissa W. Ong, Jennifer L. Barney, Tyson Barrett, Eric B. Lee, Michael Levin, Michael P. Twohig Jun 2019

The Role Of Psychological Inflexibility And Self-Compassion In Acceptance And Commitment Therapy For Clinical Perfectionism, Clarissa W. Ong, Jennifer L. Barney, Tyson Barrett, Eric B. Lee, Michael Levin, Michael P. Twohig

Psychology Faculty Publications

The current study examined psychological inflexibility and self-compassion as theoretically relevant mediators and moderators of outcomes following acceptance and commitment therapy (ACT) for clinical perfectionism. Fifty-three participants with clinical perfectionism were randomized to either a 10-session ACT condition or a 14-week waitlist control condition (only 39 completed the post treatment assessment). Outcomes tested include concern over mistakes, doubting of actions, personal standards, quality of life, symptom distress and functional impairment, and valued action. Multilevel modeling analyses showed reduced psychological inflexibility mediated the relationship between condition and higher quality of life and increased self-compassion mediated the relationship between condition and decreased ...


Exploring The Impact Of Positive Peer Views Of Girls On School Engagement In Middle School Girls, Christine E. Hansen May 2019

Exploring The Impact Of Positive Peer Views Of Girls On School Engagement In Middle School Girls, Christine E. Hansen

All Graduate Theses and Dissertations

This study focused on the types of messages female middle school students receive about their gender from their peers. Specifically, it looked at microaggressions, which are sexist messages from peers, and microaffirmations, which are positive and affirming messages from peers. There were four goals of this study. First, to check if the Students Affirming Girls in Middle School scale (SAG-MS), a scale created for this study, could consistently measure microaggressions and microaffirmations. Second, to look at the relationship between when girls experience puberty and microaggressions and microaffirmations. Third, to measure any differences in the number of microaggressions and microaffirmations girls ...


Baseline Cultural Competence In Physician Assistant Students, Melanie M. Domenech Rodríguez, Paula B. Phelps, H. Cathleen Tarp Apr 2019

Baseline Cultural Competence In Physician Assistant Students, Melanie M. Domenech Rodríguez, Paula B. Phelps, H. Cathleen Tarp

Psychology Faculty Publications

Purpose

Cultural competence is a critical component in health care services. The relationship between health disparities and prejudice and discrimination is well documented. Prejudicial attitudes and discriminatory behavior are modifiable through training yet few programs have evidence-based training. No published data has reported on baseline levels of cultural competencies in medical trainees which is necessary for tailoring programs appropriate to the audience. This manuscript fills that gap by reporting on data from three cohorts of first-year Physician Assistant (PA) students (N = 216). We examined students’ baseline levels with special attention to differences in cultural competence constructs across age, gender, and ...


Examining Quadratic Relationships Between Traits And Methods In Two Multitrait-Multimethod Models, Fred A. Hintz, Christian Geiser, G. Leonard Burns, Mateu Servera Mar 2019

Examining Quadratic Relationships Between Traits And Methods In Two Multitrait-Multimethod Models, Fred A. Hintz, Christian Geiser, G. Leonard Burns, Mateu Servera

Psychology Faculty Publications

Multitrait-multimethod (MTMM) analysis is one of the most frequently employed methods to examine the validity of psychological measures. Confirmatory factor analysis (CFA) is a commonly used analytic tool for examining MTMM data through the specification of trait and method latent variables. Most contemporary CFA-MTMM models either do not allow estimating correlations between the trait and method factors or they are restricted to linear trait-method relationships. There is no theoretical reason why trait and method relationships should always be linear, and quadratic relationships are frequently proposed in the social sciences. In this article, we present two approaches for examining quadratic relations ...

Neuropsychiatric Symptoms In Patients With Dementia And The Longitudinal Costs Of Informal Care In The Cache County Population, Gail B. Rattinger, Chelsea L. Sanders, Elizabeth Vernon, Sarah Schwartz, Stephanie Behrens, Constantine G. Lyketsos, Joann T. Tschanz

Psychology Faculty Publications

Introduction

Severity of dementia and neuropsychiatric symptoms contribute to increasing informal care costs. We examined which neuropsychiatric symptoms subdomains (NPS-SD) were associated with informal costs in a population-based sample.

Methods

Dementia progression and informal costs (2015 dollars) were estimated from the Cache County Dementia Progression Study. Overall NPS and specific NPS-SD were assessed with the Neuropsychiatric Inventory. Generalized Estimating Equations (GEE with gamma-distribution/log-link) modeled the relationship between NPS-SDs and informal cost trajectories.

Results

Two hundred eighty participants (52.1% female; age M = 85.67, SD = 5.60) exhibited an adjusted cost increase of 5.6% (P = .005), 6.4 ...


Strategies For Selecting, Managing, And Engaging Undergraduate Coauthors: A Multi-Site Perspective, Jenna L. Scisco, Jennifer A. Mccabe, Albee Therese O. Men-Doza, Marianne Fallon, Melanie M. Domenech Rodríguez Feb 2019

Strategies For Selecting, Managing, And Engaging Undergraduate Coauthors: A Multi-Site Perspective, Jenna L. Scisco, Jennifer A. Mccabe, Albee Therese O. Men-Doza, Marianne Fallon, Melanie M. Domenech Rodríguez

Psychology Faculty Publications

In 2018, we delivered a symposium on publishing with undergraduate coauthors in the Psi Chi Journal of Psychological Research (Fallon, 2018a; Fallon and Domenech Rodríguez, 2018a,b; Fallon and Scisco, 2018; McCabe and Mendoza, 2018). Based on our collective experience, we identified three common challenges: effectively selecting, managing, and engaging students throughout the publication process. We use our perspectives from different institutions (i.e., small liberal arts colleges, mid-sized regional universities, and a large research university) and evidence from past research to provide strategies to successfully meet these challenges. Ultimately, the actionable strategies we describe could be used by a ...

Identification And Transformation Difficulty In Problem Solving: Electrophysiological Evidence From Chunk Decomposition, Zhonglu Zhang, Yu Luo, Chaolun Wang, Christopher M. Warren, Qi Xia, Qiang Xing, Bihua Cao, Yi Lei, Hong Li

Psychology Faculty Publications

A wealth of studies have investigated how to overcome experience-based constraints in creative problem solving. One such experience-based constraint is the tendency for people to view tightly organized visual stimuli as single, unified percepts, even when decomposition of those stimuli into component parts (termed chunk decomposition) would facilitate problem solving. The current study investigates the neural underpinnings of chunk decomposition in creative problem solving by analyzing event-related potentials. In two experiments, participants decomposed Chinese characters into the character’s component elements and then used the base elements to form a new valid character. The action could require decomposing a “tight ...


Neural Correlates Of Interval Timing Deficits In Schizophrenia, Ariel W. Snowden, Catalin V. Buhusi Jan 2019

Neural Correlates Of Interval Timing Deficits In Schizophrenia, Ariel W. Snowden, Catalin V. Buhusi

Psychology Faculty Publications

Previous research has shown that schizophrenia (SZ) patients exhibit impairments in interval timing. The cause of timing impairments in SZ remains unknown but may be explained by a dysfunction in the fronto-striatal circuits. Although the current literature includes extensive behavioral data on timing impairments, there is limited focus on the neural correlates of timing in SZ. The neuroimaging literature included in the current review reports hypoactivation in the dorsal-lateral prefrontal cortex (DLPFC), supplementary motor area (SMA) and the basal ganglia (BG). Timing deficits and deficits in attention and working memory (WM) in SZ are likely due to a dysfunction of ...


Autoscore: An Open-Source Automated Tool For Scoring Listener Perception Of Speech, Stephanie A. Borrie, Tyson S. Barrett, Sarah E. Yoho Jan 2019

Autoscore: An Open-Source Automated Tool For Scoring Listener Perception Of Speech, Stephanie A. Borrie, Tyson S. Barrett, Sarah E. Yoho

Psychology Faculty Publications

Speech perception studies typically rely on trained research assistants to score orthographic listener transcripts for words correctly identified. While the accuracy of the human scoring protocol has been validated with strong intra- and inter-rater reliability, the process of hand-scoring the transcripts is time-consuming and resource intensive. Here, an open-source computer-based tool for automated scoring of listener transcripts is built (Autoscore) and validated on three different human-scored data sets. Results show that not only is Autoscore highly accurate, achieving approximately 99% accuracy, but extremely efficient. Thus, Autoscore affords a practical research tool, with clinical application, for scoring listener intelligibility of speech.


Newborn And Infant Hearing Screening Facing Globally Growing Numbers Of People Suffering From Disabling Hearing Loss, Katrin Neumann, Shelly Chadha, George Tavartkiladze, Xingkuan Bu, Karl R. White Jan 2019

Newborn And Infant Hearing Screening Facing Globally Growing Numbers Of People Suffering From Disabling Hearing Loss, Katrin Neumann, Shelly Chadha, George Tavartkiladze, Xingkuan Bu, Karl R. White

Psychology Faculty Publications

Recent prevalence estimates indicate that in 2015 almost half a billion people—about 6.8% of the world’s population—had disabling hearing loss and that prevalence numbers will further increase. The World Health Organization (WHO) currently estimates that at least 34 million children under the age of 15 have disabling hearing loss. Based on a 2012 WHO report, approximately 7.5 million of these children were under the age of 5 years. This review article focuses on the importance of high-quality newborn and infant hearing screening (NIHS) programs as one strategy to ameliorate disabling hearing loss as a global ...


Assessing The Effects Of Motivative Augmentals, Pay-For-Performance, And Implicit Verbal Responding On Cooperation, Sharlet D. Rafacz, Ramona A. Houmanfar, Gregory S. Smith, Michael E. Levin Jan 2019

Assessing The Effects Of Motivative Augmentals, Pay-For-Performance, And Implicit Verbal Responding On Cooperation, Sharlet D. Rafacz, Ramona A. Houmanfar, Gregory S. Smith, Michael E. Levin

Psychology Faculty Publications

Motivative augmentals are rules or statements that temporarily change the effectiveness of a consequence, similar to establishing operations for nonverbal consequences (Hayes, Barnes-Holmes, & Roche, 2001). Many communications by an organization's leadership may function as such and alter the function of stimuli in the workplace, which in turn may influence employee behaviors (Houmanfar & Rodrigues, 2012). There is a lack of experimental research regarding this, however, particularly under different organizational pay systems (i.e., financial contingencies), which have been repeatedly shown to influence performance (e.g., Gupta & Shaw, 1998; Locke, Feren, McCaleb, Shaw, & Denny, 1980). The current study sought to compare the two by measuring the effect of motivational statements on individual versus cooperative responding under two different pay-for-performance contingencies in an organizational analogue. Stimuli for the motivational statements were selected utilizing an Implicit Relational Assessment Procedure (IRAP) with one group of participants, and these statements were then tested under piece-rate and profit-share conditions with a second group of participants in a counterbalanced reversal design. Results ...

Counseling Competencies In Audiology: A Modified Delphi Study, Alex Meibos, Karen F. Muñoz, Michael P. Twohig

Psychology Faculty Publications

Purpose: Counseling practices in audiology play a critical role in helping patients and families understand, accept, and adjust to the dynamic impacts ear related disorders have on their lives. The purpose of this study was to identify what competencies (i.e., knowledge, skills, and attitudes) are important for audiologists to possess to provide effective counseling in practice.

Method: A modified Delphi study design was used to survey a panel of thirty-three professionals with expertise in audiologic counseling from five different countries. In the first survey round, experts were asked to respond to three open-ended prompts. Responses were condensed and revised ...


A Randomized Controlled Trial Of Acceptance And Commitment Therapy For Clinical Perfectionism, Clarissa W. Ong, Eric B. Lee, Jennifer Krafft, Carina L. Terry, Tyson S. Barrett, Michael E. Levin, Michael P. Twohig Jan 2019

A Randomized Controlled Trial Of Acceptance And Commitment Therapy For Clinical Perfectionism, Clarissa W. Ong, Eric B. Lee, Jennifer Krafft, Carina L. Terry, Tyson S. Barrett, Michael E. Levin, Michael P. Twohig

Psychology Faculty Publications

Clinical perfectionism is characterized by imposing excessively high standards on oneself and experiencing severe distress when standards are not met. It has been found to contribute to the development and maintenance of various clinical presentations including anxiety, obsessive-compulsive, and eating disorders. The present study tested the efficacy of ten weekly individual sessions of acceptance and commitment therapy (ACT) relative to a waitlist control on clinical perfectionism and global outcomes among 53 individuals with clinical perfectionism. ACT is a process-based therapy that targets maladaptive underlying processes (e.g., rigid adherence to unrealistic high standards) rather than symptom topography (e.g., anxiety ...


Measuring Psychological Inflexibility In Adult And Child Hearing Loss., Clarissa W. Ong, J. J. Whicker, Karen F. Munoz, Michael P. Twohig Jan 2019

Measuring Psychological Inflexibility In Adult And Child Hearing Loss., Clarissa W. Ong, J. J. Whicker, Karen F. Munoz, Michael P. Twohig

Psychology Faculty Publications

Objective: Hearing loss is a chronic condition that impacts functioning among individuals with hearing loss and caregivers of children with hearing loss. Even though treatments for hearing loss can alleviate functional impairment, psychological factors like psychological inflexibility may interfere with treatment engagement and adherence, undermining the benefits of treatment. Measuring psychological inflexibility may inform care providers’ case conceptualization, improving the quality and precision of audiological interventions. Thus, the current study aimed to develop and validate measures of psychological inflexibility in hearing loss for adults and caregivers of children with hearing loss.

Design: Participants were invited to complete an online survey ...


The Potential Benefits Of Flexibility For Dissemination And Implementation: Acceptance And Commitment Therapy As An Example, Michael E. Levin, Brooke M. Smith, Gregory S. Smith Jan 2019

The Potential Benefits Of Flexibility For Dissemination And Implementation: Acceptance And Commitment Therapy As An Example, Michael E. Levin, Brooke M. Smith, Gregory S. Smith

Psychology Faculty Publications

Our commentary on the article by Fixsen and Blase (2018) highlights some of the converging and diverging strategies between the Teaching-Family Model (TFM) and the dissemination and implementation of acceptance and commitment therapy (ACT). We focus primarily on the potential benefits of flexibility in areas including theory, methodology, and intervention protocols. Examples include the use of middle level terms, randomized controlled trial methods, protocols focused more on function than specific topography, and an open, collaborative approach to dissemination. We also note how this broader set of strategies can be made coherent and progressive through a careful connection back to contextual ...


Longitudinal Effects Of A 2-Year Meditation And Buddhism Program On Well-Being, Quality Of Life, And Valued Living, Brooke M. Smith, Clarissa W. Ong, Tyson S. Barrett, Ellen J. Bluett, Timothy A. Slocum, Michael P. Twohig Jan 2019

Longitudinal Effects Of A 2-Year Meditation And Buddhism Program On Well-Being, Quality Of Life, And Valued Living, Brooke M. Smith, Clarissa W. Ong, Tyson S. Barrett, Ellen J. Bluett, Timothy A. Slocum, Michael P. Twohig

Psychology Faculty Publications

Objectives: Most research on mindfulness and meditation has focused on structured therapeutic interventions, such as mindfulness-based stress reduction, or meditation retreats. Such programs have received moderate empirical support for improving psychological outcomes in clinical and nonclinical populations, but there remains a paucity of research on intensive or long-term mindfulness or meditation programs for experienced practitioners, especially those that incorporate Buddhist teachings. The purpose of the current study was to investigate the effects of a long-term integrated mindfulness/meditation and Buddhism program, Dharma in Daily Life (DIDL).

Methods: Well-being, quality of life, valued living, and theorized processes of change were measured ...


Psychological Inflexibility Predicts Suicidality Over Time In College Students, Jennifer Krafft, E. Tish Hicks, Sallie A. Mack, Michael E. Levin Jan 2019

Psychological Inflexibility Predicts Suicidality Over Time In College Students, Jennifer Krafft, E. Tish Hicks, Sallie A. Mack, Michael E. Levin

Psychology Faculty Publications

Objective:

It is essential to identify modifiable risk factors that can be targeted to reduce suicidal ideation (SI) and behavior in college students. Psychological inflexibility, a pattern of responding to internal experiences in a literal and rigid way, and attempting to control those experiences even when it interferes with valued living, could theoretically lead to SI or increase its intensity.

Method:

Psychological inflexibility and its component processes were tested as a predictor of SI in a longitudinal survey of college students (n = 603, age M = 20.62, 68.9% female, and 94.0% White) in a series of cross-sectional and ...

Clinical impact statement:

Question: The goal of this paper is to present the manner in which ACT is initiated. Findings: There are specific theoretical elements of ACT that suggest certain approaches be taken at the beginning of therapy. Meaning: Before starting ACT with a new ...


A Review Of Aaq Variants And Other Context-Specific Measures Of Psychological Flexibility, Clarissa Ong, Eric B. Lee, Michael Levin, Michael P. Twohig Jan 2019

A Review Of Aaq Variants And Other Context-Specific Measures Of Psychological Flexibility, Clarissa Ong, Eric B. Lee, Michael Levin, Michael P. Twohig

Psychology Faculty Publications

Psychological flexibility refers to a way of interacting with internal experiences and the external environment that advances one toward chosen values whereas psychological inflexibility reflects rigid adherence to ineffective responses such that valued living is compromised. Psychological flexibility is a critical variable of interest in acceptance and commitment therapy, thus, accurate assessment of this construct is pertinent to professionals in the field. Numerous measures of psychological flexibility for specific conditions exist and the psychometric validation of each of these measures varies in breadth and depth. To orient professionals to the scope of available measures as well as their psychometric properties ...

The Neuromodulatory And Hormonal Effects Of Transcutaneous Vagus Nerve Stimulation As Evidenced By Salivary Alpha Amylase, Salivary Cortisol, Pupil Diameter, And The P3 Event-Related Potential, Christopher M. Warren, Klodiana D. Tona, L. Ouwerkerk, Jeroen Van Paridon, Fenna Poletiek, Henk Van Steenbergen, Jos A. Bosch, Sander Nieuwenhuis

Psychology Faculty Publications

Background

Transcutaneous vagus nerve stimulation (tVNS) is a new, non-invasive technique being investigated as an intervention for a variety of clinical disorders, including epilepsy and depression. It is thought to exert its therapeutic effect by increasing central norepinephrine (NE) activity, but the evidence supporting this notion is limited.

Objective

In order to test for an impact of tVNS on psychophysiological and hormonal indices of noradrenergic function, we applied tVNS in concert with assessment of salivary alpha amylase (SAA) and cortisol, pupil size, and electroencephalograph (EEG) recordings.

Methods

Across three experiments, we applied real and sham tVNS to 61 healthy participants ...

Chronic Health Conditions Among Us Veterans Discharged From Military Service For Misconduct, Emily Brignone, Jamison D. Fargo, Rebecca K. Blais, Adi V. Gundlapalli

Psychology Faculty Publications

Veterans who are discharged from military service due to misconduct are vulnerable to negative health-related outcomes, including homelessness, incarceration, and suicide. We used national data from the Veterans Health Administration for 218,608 veterans of conflicts in Iraq and Afghanistan that took place after the events of September 11, 2001, to compare clinical diagnoses between routinely-discharged (n = 203,174) and misconduct-discharged (n = 15,433) veterans. Misconduct-discharged veterans had significantly higher risk for all mental health conditions (adjusted odds ratio [AOR] range, 2.5–8.0) and several behaviorally linked chronic health conditions (AOR range, 1.2–5.9). Misconduct-discharged veterans ...


Cognitive Load Affects Numerical And Temporal Judgments In Distinct Ways, Karina Hamamouche, Maura Keefe, Kerry E. Jordan, Sara Cordes Oct 2018

Cognitive Load Affects Numerical And Temporal Judgments In Distinct Ways, Karina Hamamouche, Maura Keefe, Kerry E. Jordan, Sara Cordes

Psychology Faculty Publications

Prominent theories suggest that time and number are processed by a single neural locus or a common magnitude system (e.g., Meck and Church, 1983; Walsh, 2003). However, a growing body of literature has identified numerous inconsistencies between temporal and numerical processing, casting doubt on the presence of such a singular system. Findings of distinct temporal and numerical biases in the presence of emotional content (Baker et al., 2013; Young and Cordes, 2013) are particularly relevant to this debate. Specifically, emotional stimuli lead to temporal overestimation, yet identical stimuli result in numerical underestimation. In the current study, we ...


Continuous Nicotine Exposure Does Not Affect Resurgence Of Alcohol Seeking In Rats, Charles C. J. Frye, Jillian M. Rung, Rusty W. Nall, Ann Galizio, Jeremy M. Haynes, Amy L. Odum Aug 2018

Continuous Nicotine Exposure Does Not Affect Resurgence Of Alcohol Seeking In Rats, Charles C. J. Frye, Jillian M. Rung, Rusty W. Nall, Ann Galizio, Jeremy M. Haynes, Amy L. Odum

Psychology Faculty Publications

Alcohol is the most commonly used drug in the United States and alcohol abuse can lead to alcohol use disorder. Alcohol use disorder is a persistent condition and relapse rates following successful remission are high. Many factors have been associated with relapse for alcohol use disorder, but identification of these factors has not been well translated into preventative utility. One potentially important factor, concurrent nicotine use, has not been well investigated as a causal factor in relapse for alcohol use disorder. Nicotine increases the value of other stimuli in the environment and may increase the value of alcohol. If nicotine ...


A Population-Based Model Of The Temporal Memory In The Hippocampus, Sorinel A. Oprisan, Mona Buhusi, Catalin V. Buhusi Aug 2018

A Population-Based Model Of The Temporal Memory In The Hippocampus, Sorinel A. Oprisan, Mona Buhusi, Catalin V. Buhusi

Psychology Faculty Publications

Spatial and temporal dimensions are fundamental for orientation, adaptation, and survival of organisms. Hippocampus has been identified as the main neuroanatomical structure involved both in space and time perception and their internal representation. Dorsal hippocampus lesions showed a leftward shift (toward shorter durations) in peak-interval procedures, whereas ventral lesions shifted the peak time toward longer durations. We previously explained hippocampus lesion experimental findings by assuming a topological map model of the hippocampus with shorter durations memorized ventrally and longer durations more dorsal. Here we suggested a possible connection between the abstract topological maps model of the hippocampus that stored reinforcement ...


Inactivation Of The Medial-Prefrontal Cortex Impairs Interval Timing Precision, But Not Timing Accuracy Or Scalar Timing In A Peak-Interval Procedure In Rats, Catalin V. Buhusi, Marcelo B. Reyes, Cody-Aaron Gathers, Sorinel A. Oprisan, Mona Buhusi Jun 2018

Inactivation Of The Medial-Prefrontal Cortex Impairs Interval Timing Precision, But Not Timing Accuracy Or Scalar Timing In A Peak-Interval Procedure In Rats, Catalin V. Buhusi, Marcelo B. Reyes, Cody-Aaron Gathers, Sorinel A. Oprisan, Mona Buhusi

Psychology Faculty Publications

Motor sequence learning, planning and execution of goal-directed behaviors, and decision making rely on accurate time estimation and production of durations in the seconds-to-minutes range. The pathways involved in planning and execution of goal-directed behaviors include cortico-striato-thalamo-cortical circuitry modulated by dopaminergic inputs. A critical feature of interval timing is its scalar property, by which the precision of timing is proportional to the timed duration. We examined the role of medial prefrontal cortex (mPFC) in timing by evaluating the effect of its reversible inactivation on timing accuracy, timing precision and scalar timing. Rats were trained to time two durations in a ...

The Influence Of A Personal Values Intervention On Cold Pressor-Induced Distress Tolerance, Brooke M. Smith, Jennifer L. Villatte, Clarissa W. Ong, Grayson M. Butcher, Michael P. Twohig, Michael Levin, S. C. Hayes

Psychology Faculty Publications

Research has demonstrated that values and acceptance interventions can increase distress tolerance, but the individual contribution of each remains unclear. The current study examined the isolated effect of a values intervention on immersion time in a cold pressor. Participants randomized to Values (n = 18) and Control (n = 14) conditions completed two cold pressor tasks, separated by a 30-minute values or control intervention. Immersion time increased 51.06 seconds for participants in the Values condition and decreased by 10.79 seconds for those in the Control condition. Increases in self-reported pain and distress predicted decreases in immersion time for Control, but ...

Commentary: Are Groups More Or Less Than The Sum Of Their Members? The Moderating Role Of Individual Identification, Zhonglu Zhang, Christopher M. Warren, Yi Lei, Qiang Xing, Hong Li

Psychology Faculty Publications

Baumeister et al. (2016) proposed that people perform better in groups only “when members of the group are individually identified and responsible” (p. 2), and conversely, that people perform worse in groups when they “are not publicly identified or rewarded” (p. 2). In other words, they emphasized how individual responsibility contributes to group success. However, we argue that shared identity, whereby group members share a common responsibility, can also facilitate group success in many circumstances, and thus should not be discounted. Several authors have shared the same view in the open peer commentary published in Behavioral and Brain Sciences about ...

Psychology Faculty Publications

Children with autism spectrum disorder (ASD) present with complex medical problems that are often exacerbated by a range of other intellectual and psychiatric comorbidities. These children receive care for their physical and mental health from a range of providers within numerous child-serving systems, including their primary care clinic, school, and the home and community. Given the longitudinal nature in which care is provided for this chronic disorder, it is particularly necessary for services and providers to coordinate their care to ensure optimal efficiency and effectiveness. There are 2 primary venues that serve as a “home” for coordination of service provision ...
