Stimulus Complexity And Chunk Tightness Interact To Impede Perceptual Restructuring During Problem Solving, Zhonglu Zhang, Christopher M. Warren, Yi Lei, Qiang Xing, Hong Li

Psychology Faculty Publications

The mutual influence of stimulus complexity and chunk tightness on perceptual restructuring was examined using a chunk decomposition task (CDT). Participants attempted to remove components of Chinese characters in order to produce new, valid characters. Participants had their electroencephalogram recorded while completing a CDT in conditions of low or high stimulus complexity, crossed with two levels of chunk tightness. Tight chunks overlapped spatially whereas loose chunks did not. Both increasing chunk tightness and increasing stimulus complexity impaired performance (lower accuracy, longer reaction times), and these factors interacted such that highly complex, tight chunks produced the worst performance. These factors also …

Promoting Healthy Decision-Making Via Natural Environment Exposure: Initial Evidence And Future Directions, Meredith S. Berry, Meredith A. Repke, Alexander L. Metcalf, Kerry Jordan

Psychology Faculty Publications

Research within psychology and other disciplines has shown that exposure to natural environments holds extensive physiological and psychological benefits. Adding to the health and cognitive benefits of natural environments, evidence suggests that exposure to nature also promotes healthy human decision-making. Unhealthy decision-making (e.g., smoking, non-medical prescription opioid misuse) and disorders associated with lack of impulse control [e.g., tobacco use, opioid use disorder (OUD)], contribute to millions of preventable deaths annually (i.e., 6 million people die each year of tobacco-related illness worldwide, deaths from opioids from 2002 to 2017 have more than quadrupled in the United States alone). Impulsive and unhealthy …

Natural Categorization: Electrophysiological Responses To Viewing Natural Versus Built Environments, Salif Mahamane, Nick Wan, Alexis Porter, Allison S. Hancock, Justin Campbell, M. S. Lyons, Kerry Jordan

Psychology Faculty Publications

Environments are unique in terms of structural composition and evoked human experience. Previous studies suggest that natural compared to built environments may increase positive emotions. Humans in natural environments also demonstrate greater performance on attention-based tasks. Few studies have investigated cortical mechanisms underlying these phenomena or probed these differences from a neural perspective. Using a temporally sensitive electrophysiological approach, we employ an event-related, implicit passive viewing task to demonstrate that in humans, a greater late positive potential (LPP) occurs with exposure to built than natural environments, resulting in a faster return of activation to pre-stimulus baseline levels when viewing natural …

A Religious Paradox: Can Priming Ideas Of God Reduce Rape Victim Blame?, Emma G. Heath, Kathryn Sperry

Psychology Faculty Publications

Rape victim blame contributes to unreported incidents of sexual assault and failure to support victims (Ahrens in American Journal of Community Psychology, 38(3-4), 263-274, 2006). The present study investigated the relationship between religiosity, religious priming, and rape victim blame. Using an online Qualtrics panel, 247 U.S. participants were randomly assigned to either a neutral prime or a religious prime. They then read a short vignette of an acquaintance rape scenario and answered questions regarding perceptions of victim blame, victim credibility, benevolent and hostile sexism, religiosity, religious fundamentalism, and Rape Myth Acceptance (RMA). Results revealed that the religious prime …

Comparing Effects Of Acceptance Training And Psychoeducation On Hoarding Symptoms, Clarissa W. Ong, Jennifer Krafft, Michael E. Levin, Michael P. Twohig

Psychology Faculty Publications

Hoarding symptoms include difficulty letting go of possessions, excessive acquisition, and clutter that precludes use of active living spaces. The current study compared the effects of acceptance training to psychoeducation on hoarding severity in a sample of college students with elevated hoarding symptoms. Participants (N = 47) completed self-report measures at baseline, posttest, and one-week follow-up and an in vivo discarding behavioral task at posttest. There were no differences in self-reported outcomes between conditions over time, suggesting acceptance training was not more effective than psychoeducation. Significant and large effect sizes for hoarding severity and maladaptive hoarding cognitions were found …

Lgbtq+ Emerging Adults Perceptions Of Discrimination And Exclusion Within The Lgbtq+ Community, Joshua Glenn Parmenter, Renee Vickerman Galliher, Adam D. A. Maughan

Psychology Faculty Publications

Research on LGBTQ+ emerging adult populations has primarily focused on discrimination that is experienced within the heterodominant culture. Due to systems of oppression and the forces of power and privilege, some sexual and gender minorities experience isolation and discrimination not only within the heterodominant culture, but within the LGBTQ+ community as well. Fourteen lesbian, gay, bisexual, transgender, or queer/questioning (LGBTQ+) young adults (20-25 years) with a diverse array of intersecting identities (e.g., gender, racial, ethnic, religious, cultural) participated in semi-structured individual interviews and focus groups. Participants reported on experiences of biphobia, acephobia, transphobia, gatekeeping the community, LGBTQ+ people of colour’s …

A Randomized Trial Of Acceptance And Commitment Therapy And Traditional Cognitive-Behavioral Therapy Self-Help Books For Social Anxiety, Jennifer Krafft, Michael P. Twohig, Michael E. Levin

Psychology Faculty Publications

Background: Self-help resources such as books may help meet critical mental health needs in college students, but there is insufficient evidence on whether and how such books work. This randomized trial compared acceptance and commitment therapy (ACT) and traditional cognitive behavior therapy (tCBT) self-help books for social anxiety, a common concern with notable barriers to treatment seeking.

Methods: A sample of college students (n = 102) with social anxiety was randomly assigned to use one of the two self-help books over eight weeks.

Results: Improvements were observed in both conditions across all outcomes (social anxiety, general well-being, and social …

Experiential Avoidance And Negative Affect As Predictors Of Daily Drinking, Jason B. Luoma, Benjamin G. Pierce, Michael E. Levin

Psychology Faculty Publications

People who drink alcohol to cope with negative affect tend to drink more and experience more frequent negative alcohol-related consequences. Experiential avoidance, the tendency to avoid, suppress, or otherwise attempt to control unwanted inner experiences, is a largely pathological process that may help account for how negative affect is linked to increased alcohol consumption. However, research to-date has typically used global, trait-like measures, which limit our understanding of the conditions under which experiential avoidance is problematic. The current study tested both between-person (trait) and within-person (daily) variation in experiential avoidance and negative affect as predictors of solitary and social drinking …

A Randomized Dismantling Trial Of The Open And Engaged Components Of Acceptance And Commitment Therapy In An Online Intervention For Distressed College Students, Michael E. Levin, Jennifer Krafft, Elizabeth T. Hicks, Michael P. Twohig, Benjamin G. Pierce

Psychology Faculty Publications

This dismantling trial compared the effects of a full online Acceptance and Commitment Therapy (ACT) intervention to the isolated effects of the Open (i.e., acceptance, cognitive defusion) and Engaged (i.e., values, committed action) components of ACT. A sample of 181 distressed college students were randomized to one of four conditions: a 12-session full ACT website (Full), a version targeting the Open components (Open), a version targeting the Engaged components (Engaged), or waitlist.

Beyond Acceptance And Commitment Therapy: Process-Based Therapy, Clarissa W. Ong, Michael E. Levin, Michael P. Twohig

Psychology Faculty Publications

This article describes process-based therapy (PBT) as a natural evolution toward more effective and efficient mental healthcare. Using acceptance and commitment therapy as an example of an early prototype of PBT, this paper explicates the broader features of PBT and the shift in mindset researchers and clinicians will need to take to fully embrace PBT with respect to assessment, conceptualization, and intervention. In addition, the paper enumerates challenges to implementing the PBT model and proposes recommendations for circumventing these challenges in the areas of theory development, research methodology, and clinical practice. Finally, we make the argument shifting to PBT is …

Implementing A Web-Based Cognitive Defusion Program To Target Negative Self-Referential Thoughts In College Students: A Pilot Study, Clarie-Ann Henriques Wollach, Leeann Cardaciotto, Michael E. Levin, Sharon Lee Armstrong

Psychology Faculty Publications

Cognitive defusion may enhance healthy coping with negative self-referential thoughts amongst college students. However, research is needed to examine how to effectively introduce and teach defusion to this population. The current pilot study tested the usability of and satisfaction with the D-FUSE program, a single-session, web-based program for a mixed sample of undergraduates and its effectiveness in producing improvements in cognitive defusion and self-criticism. In an undergraduate sample (N = 141), the D-FUSE program was found to be usable and satisfactory. Program engagement rendered significant reductions in the believability of and emotional discomfort produced by negative self-referential thoughts. Further improvements …

The Empirical Status Of Acceptance And Commitment Therapy: A Review Of Meta-Analyses, Andrew T. Gloster, Noemi Walder, Michael E. Levin, Michael P. Twohig, Maria Karekla

Psychology Faculty Publications

The efficacy of Acceptance and Commitment Therapy (ACT) has been evaluated in many randomized controlled trials investigating a broad range of target conditions. This paper reviews the meta-analytic evidence on ACT. The 20 included meta-analyses reported 100 controlled effect sizes across n = 12,477 participants. Controlled effect sizes were grouped by target conditions and comparison group. Results showed that ACT is efficacious for all conditions examined, including anxiety, depression, substance use, pain, and transdiagnostic groups. Results also showed that ACT was generally superior to inactive controls (e.g. waitlist, placebo), treatment as usual, and most active intervention conditions (excluding CBT). Weaknesses …

Pilot Evaluation Of The Stop, Breathe & Think Mindfulness App For Student Clients On A College Counseling Center Waitlist, Michael E. Levin, Elizabeth T. Hicks, Jennifer Krafft

A Psychometric Comparison Of Psychological Inflexibility Measures: Discriminant Validity And Item Performance, Clarissa W. Ong, Benjamin G. Pierce, Julie M. Petersen, Jennifer L. Barney, Jeremiah E. Fruge, Michael E. Levin, Michael P. Twohig

Psychology Faculty Publications

Psychological inflexibility is a rigid behavioral pattern that interferes with engagement in personally meaningful activities; it is the hypothesized root of suffering in acceptance and commitment therapy (ACT). Thus, the quality of its measurement affects the research, theory, and practice of ACT. The current study aimed to evaluate the discriminant validity and item performance of four measures of psychological inflexibility: the Acceptance and Action Questionnaire—II (AAQ-II), a revised version of the AAC-II (AAQ-3), the Brief Experiential Avoidance Questionnaire (BEAQ), and the Comprehensive assessment of Acceptance and Commitment Therapy processes (CompACT). We analyzed data from community (n = 253), student …

An Examination Of The Relationship Between Perfectionism And Neurological Functioning, Julie M. Petersen, Clarissa W. Ong, Allison S. Hancock, Ronald B. Gillam, Michael E. Levin, Michael P. Twohig

Psychology Faculty Publications

Clinical perfectionism is the rigid pursuit of high standards, interfering with functioning. Little research has explored neural patterns in clinical perfectionism. The present study explores neural correlates of clinical perfectionism, before and after receiving ten 50-minute, weekly sessions of acceptance and commitment therapy (ACT), as compared to low-perfectionist controls, in specific cortical structures: the dorsolateral prefrontal cortex (DLPFC), medial prefrontal cortex (MPFC), right inferior parietal lobule (IPL). Participants in the perfectionist condition (n = 43) were from a randomized controlled trial evaluating ACT for clinical perfectionism and low-perfectionist controls were undergraduate students (n = 12). Participants completed three tasks (editing …

A Preliminary Investigation Of The Effect Of Acceptance And Commitment Therapy On Neural Activation In Clinical Perfectionism, Clarissa W. Ong, Allison S. Hancock, Tyson S. Barrett, Eric B. Lee, Nicholas Wan, Ronald B. Gillam, Michael E. Levin, Michael P. Twohig

Psychology Faculty Publications

Clinical perfectionism is associated with various cognitive processes including performance monitoring and emotion regulation. This exploratory study analyzed neurological data from a randomized controlled trial for clinical perfectionism that compared acceptance and commitment therapy (ACT) to a waitlist control. The objective was to assess the effect of ACT on neural activation. Twenty-nine participants underwent a functional near-infrared spectroscopy assessment during which they completed behavioral tasks designed to elicit error detection and error generation at pre- and posttreatment. The hemodynamic response function (HRF) in the dorsolateral prefrontal cortex, dorsomedial prefrontal cortex, and right inferior parietal lobe was analyzed using mixed effects …
