A Functional Near-Infrared Spectroscopic Investigation Of Speech Production During Reading, Nick Wan, Allison S. Hancock, Todd K. Moon, Ronald B. Gillam

Psychology Faculty Publications

This study was designed to test the extent to which speaking processes related to articulation and voicing influence Functional Near Infrared Spectroscopy (fNIRS) measures of cortical hemodynamics and functional connectivity. Participants read passages in three conditions (oral reading, silent mouthing, and silent reading) while undergoing fNIRS imaging. Area under the curve (AUC) analyses of the oxygenated and deoxygenated hemodynamic response function concentration values were compared for each task across five regions of interest. There were significant region main effects for both oxy and deoxy AUC analyses, and a significant region x task interaction for deoxy AUC favoring the oral reading …

The Impact Of Premeeting Talk On Group Performance, Michael Yoerger, Joseph A. Allen, John Crowe

Psychology Faculty Publications

Interactions that occur prior to a meeting constitute premeeting talk (PMT). Of the different PMT types, research suggests that small talk PMT is especially meaningful. In this study, meeting participants’ interactions both prior to and during the meeting were video recorded, coded into sense units, and classified by coding schemes. This study investigated the influence of small talk PMT on both perceived and objective group performances, as well as the potential for positive socioemotional and problem-focused statements to serve as mediators. The results supported the mediating influence of both types of statements for only perceived performance. Our results suggest that …

Creative Self-Efficacy As Mediator Between Creative Mindsets And Creative Problem-Solving, Ryan Royston, Roni Reiter-Palmon

Psychology Faculty Publications

An emerging area of research is how one's mindset regarding the fixedness and malleability of creative ability relates to creative performance. Malleable creative mindsets tend to be positively related to creativity while fixed mindsets often show a negative association. Similarly, creative self-efficacy, or one's beliefs that they have the capacity to be creative, is also related to creative performance and creative mindsets. While previous studies tested the direct relationship between mindsets and creativity, this study tested creative self-efficacy in this relationship. A total of 152 students from a Midwestern university participated in the study. They were provided with measures of …

The Curvilinear Relationship Between Daily Time Pressure And Work Engagement: The Role Of Psychological Capital And Sleep, Xiaotian Sheng, Yuqing Wang, Wei Hong, Ze Zhu, Xichao Zhang

Psychology Faculty Publications

The present study focuses on the fluctuation in work engagement by examining the relationship between daily time pressure and daily work engagement. Based on the job demands-resources (JD-R) theory, this study also tests whether psychological capital and sleep moderate the influence of time pressure on work engagement. We conducted a diary study to gather 67 participants’ data over 10 consecutive work days (502 daily measurement points), including their daily time pressure, work engagement, and sleep quality. Our results indicate that there is a curvilinear relationship between daily time pressure and work engagement in the form of an inverted U-shape. If …

Measuring Heightened Attention To Alcohol In A Naturalistic Setting: A Validation Study, Ramey G. Monem, Mark T. Fillmore

Psychology Faculty Publications

Attentional bias to alcohol-related stimuli is believed to be an important contributor to the development and maintenance of drug abuse. There is a considerable body of research examining attentional bias, much of which has typically utilized image-display tasks as a means to assess the phenomenon. Little, however, is known about the nature of this bias in an individual’s natural environment. The current study sought to implement a novel approach to assessing attentional bias in vivo. Participants wore portable eye-tracking glasses that recorded video from their point of view and measured fixation time to objects they observed. They entered a room …

Physical Aggressiveness And Gray Matter Deficits In Ventromedial Prefrontal Cortex, David S. Chester, Donald R. Lynam, Richard Milich, C. Nathan Dewall

Psychology Faculty Publications

What causes individuals to hurt others? Since the famous case of Phineas Gage, lesions of the ventromedial prefrontal cortex (VMPFC) have been reliably linked to physically aggressive behavior. However, it is unclear whether naturally-occurring deficits in VMPFC, among normal individuals, might have widespread consequences for aggression. Using voxel based morphometry, we regressed gray matter density from the brains of 138 normal female and male adults onto their dispositional levels of physical aggression, verbal aggression, and sex, simultaneously. Physical, but not verbal, aggression was associated with reduced gray matter volume in the VMPFC and to a lesser extent, frontopolar cortex. Participants …

Effects Of Environmental Enrichment On Self-Administration Of The Short-Acting Opioid Remifentanil In Male Rats, Rebecca S. Hofford, Jonathan J. Chow, Joshua S. Beckmann, Michael T. Bardo

Psychology Faculty Publications

Background

Opioid abuse is a major problem around the world. Identifying environmental factors that contribute to opioid abuse and addiction is necessary for decreasing this epidemic. In rodents, environmental enrichment protects against the development of low dose stimulant self-administration, but studies examining the effect of enrichment and isolation (compared to standard housing) on the development of intravenous opioid self-administration have not been conducted. The present study investigated the role of environmental enrichment on self-administration of the short-acting μ-opioid remifentanil.

Methods

Rats were raised in an enriched condition (Enr), standard condition (Std), or isolated condition (Iso) beginning at 21 days of …

Print Exposure Modulates The Effects Of Repetition Priming During Sentence Reading, Matthew W. Lowder, Peter C. Gordon

Psychology Faculty Publications

Individual readers vary greatly in the quality of their lexical representations and consequently in how quickly and efficiently they can access orthographic and lexical knowledge. This variability may be explained, at least in part, by individual differences in exposure to printed language, as practice at reading promotes the development of stronger reading skills. The current eye-tracking experiment tests the hypothesis that the efficiency of word recognition during reading improves with increases in print exposure by determining whether the magnitude of the repetition priming effect is modulated by individual differences in scores on the Author Recognition Test (ART). Lexical repetition of …

Collective Impact Strategies: Introduction To The Special Issue, Joseph A. Allen, Kelly Prange, Sheridan Trent

Psychology Faculty Publications

The societal and cultural issues facing humanity are far greater than any nonprofit, for-profit, university, or government agency to address adequately alone. Whether poverty, water shortages, socio-economic inequality, natural disasters with lasting effects, or any number of other challenges facing our communities, organizations must band together to secure the impact needed to truly create change. Increasingly, communities are turning to collective impact as an approach that brings together the collective resources of multiple institutions to address a community-identified problem or need. While a somewhat new approach, there is a growing body of evidence of supporting the effectiveness of using the …

Moving Toward A Collective Impact Effort: The Volunteer Program Assessment, Sheridan Trent, Kelly Prange, Joseph A. Allen

Psychology Faculty Publications

Volunteers are essential to the operation of many nonprofits, but some experience challenges in retaining their volunteer workforce. The Volunteer Program Assessment (VPA) seeks to address this issue by helping organizations to identify strengths, growth areas, and recommendations for improving volunteer experiences. To maximize the effectiveness of VPA’s mission, the organization is moving toward a collective impact (CI) approach. Although not developed as a CI effort, the program currently exemplifies many of its characteristics, which have been instrumental in expanding reach to more organizations. We examine VPA’s alignment with collective impact and outline how VPA will continue to improve efforts.

A Subconscious Interaction Between Fixation And Anticipatory Pursuit, Scott N. J. Watamaniuk, Japjot Bal, Stephen J. Heinen

Psychology Faculty Publications

Ocular smooth pursuit and fixation are typically viewed as separate systems, yet there is evidence that the brainstem fixation system inhibits pursuit. Here we present behavioral evidence that the fixation system modulates pursuit behavior outside of conscious awareness. Human observers (male and female) either pursued a small spot that translated across a screen, or fixated it as it remained stationary. As shown previously, pursuit trials potentiated the oculomotor system, producing anticipatory eye velocity on the next trial before the target moved that mimicked the stimulus-driven velocity. Randomly interleaving fixation trials reduced anticipatory pursuit, suggesting that a potentiated fixation system interacted …

Managing Diabetes In Festive Times, Jasmin Tahmaseb-Mcconatha

Psychology Faculty Publications

Are you worried about managing your Type 2 diabetes as the holidays approach? Are you anxious about going to social gatherings? Talking about your concerns and planning can help. The diabetes crisis continues to grow creating holiday stress for patients.

Age Differences In The Desirability Of Narcissism, Kathy R. Berenson, William D. Ellison, Rachel L. Clasing

Psychology Faculty Publications

Young adult narcissism has been the focus of much discussion in the personality literature and popular press. Yet no previous studies have addressed whether there are age differences in the relative desirability of narcissistic and non-narcissistic self-descriptions, such as those presented as answer choices on the Narcissistic Personality Inventory (NPI; Raskin & Hall, 1979). In Study 1, younger age was associated with less negative evaluations of narcissistic (vs. non-narcissistic) statements in general, and more positive evaluations of narcissistic statements conveying leadership/authority. In Study 2, age was unrelated to perceiving a fictional target person as narcissistic, but younger age was associated …

Not So Bad: Avoidance And Aversive Discounting Modulate Threat Appraisal In Anterior Cingulate And Medial Prefrontal Cortex, Michael W. Schlund, Adam T. Brewer, David M. Richman, Sandy K. Magee, Simon Dymond

Psychology Faculty Publications

The dorsal anterior cingulate (adACC) and dorsal medial prefrontal cortex (dmPFC) play a central role in the discrimination and appraisal of threatening stimuli. Yet, little is known about what specific features of threatening situations recruit these regions and how avoidance may modulate appraisal and activation through prevention of aversive events. In this investigation, 30 healthy adults underwent functional neuroimaging while completing an avoidance task in which responses to an Avoidable CS+ threat prevented delivery of an aversive stimulus, but not to an Unavoidable CS+ threat. Extinction testing was also completed where CSs were presented without aversive stimulus delivery and an …

Psychological Inflexibility And Stigma: A Meta-Analytic Review, Jennifer Krafft, Jillian Ferrell, Michael E. Levin, Michael P. Twohig

Psychology Faculty Publications

Stigma is known to have major impacts on the physical and psychological health of many groups. Psychological inflexibility is a psychological process that may help explain the impact of stigma on both self and others. Accordingly, acceptance and commitment therapy (ACT), which targets psychological inflexibility, has been researched as a potential treatment for stigma. In order to provide a comprehensive overview of these issues, this paper offers a systematic review and meta-analysis of the association between psychological inflexibility and stigma, as well as a systematic review of ACT interventions for stigma. The results of the meta-analysis showed a positive, medium-to-large …

Interactive Effects Of Ovarian Steroid Hormones On Alcohol Use And Binge Drinking Across The Menstrual Cycle, Michelle M. Martel, Tory Eisenlohr-Moul, Bethan A. Roberts

Psychology Faculty Publications

Patterns and features of substance use and abuse vary across the menstrual cycle in humans. Yet, little work has systematically examined the within-person relationships between ovarian hormone changes and alcohol use across the menstrual cycle. Our study was the first to examine the roles of within-person levels of estradiol (E2) and progesterone (P4) in relation to daily alcohol use and binge drinking in young women. Participants were 22 naturally cycling women, ages 18-22, recruited through a university subject pool who reported any alcohol use and who completed a screening visit assessing study eligibility, followed by 35 subsequent days of data …

Perception Is Key? Does Perceptual Sensitivity And Parenting Behavior Predict Children's Reactivity To Others’ Emotions?, Joyce Weeland, Alithe Van Den Akker, Meike Slagt, Samuel Putnam

Psychology Faculty Publications

When interacting with other people, both children's biological predispositions and past experiences play a role in how they will process and respond to social–emotional cues. Children may partly differ in their reactions to such cues because they differ in the threshold for perceiving such cues in general. Theoretically, perceptual sensitivity (i.e., the amount of detection of slight, low-intensity stimuli from the external environment independent of visual and auditory ability) might, therefore, provide us with specific information on individual differences in susceptibility to the environment. However, the temperament trait of perceptual sensitivity is highly understudied. In an experiment, we tested whether …

Illusory Motion Reveals Velocity Matching, Not Foveation, Drives Smooth Pursuit Of Large Objects, Scott N. J. Watamaniuk, Zheng Ma, Stephen J. Heinen

Psychology Faculty Publications

When small objects move in a scene, we keep them foveated with smooth pursuit eye movements. Although large objects such as people and animals are common, it is nonetheless unknown how we pursue them since they cannot be foveated. It might be that the brain calculates an object’s centroid, and then centers the eyes on it during pursuit as a foveation mechanism might. Alternatively, the brain merely matches the velocity by motion integration. We test these alternatives with an illusory motion stimulus that translates at a speed different from its retinal motion. The stimulus was a Gabor array that translated …

A Pilot Study Of Loss Aversion For Drug And Non-Drug Commodities In Cocaine Users, Justin Charles Strickland, Joshua S. Beckmann, Craig R. Rush, William W. Stoops

Psychology Faculty Publications

Background—Numerous studies in behavioral economics have demonstrated that individuals are more sensitive to the prospect of a loss than a gain (i.e., loss aversion). Although loss aversion has been well described in “healthy” populations, little research exists in individuals with substance use disorders. This gap is notable considering the prominent role that choice and decision-making play in drug use. The purpose of this pilot study was to evaluate loss aversion in active cocaine users.

Methods—Current cocaine users (N = 38; 42% female) participated in this within-subjects laboratory pilot study. Subjects completed a battery of tasks designed to assess …

A Randomized Controlled Trial Of Multiple Versions Of An Acceptance And Commitment Therapy Matrix App For Well-Being, Jennifer Krafft, Sarah Potts, Benjamin Schoendorff, Michael E. Levin

Psychology Faculty Publications

Mobile apps may be useful in teaching psychological skills in a high-frequency, low-intensity intervention. The Acceptance and Commitment Therapy (ACT) matrix is a visual tool to help develop psychological flexibility by categorizing moment-to-moment experience and is well suited to a mobile app. This pilot study tested the effects of a simple and complex version of a novel app using the ACT matrix in two distinct samples: help-seeking individuals (n = 35) and students receiving SONA credit (n = 63). Findings indicated no differences between app conditions and a waitlist condition in the SONA credit sample. However, in the …

Mindfulness And Acceptance-Based Trainings For Fostering Self-Care And Reducing Stress In Mental Health Professionals: A Systematic Review, Myriam Rudaz, Michael P. Twohig, Clarissa W. Ong, Michael E. Levin

Psychology Faculty Publications

This review summarizes the effectiveness of Mindfulness-Based Stress Reduction (MBSR), Mindfulness-Based Cognitive Therapy (MBCT), Mindful Self-Compassion (MSC), and Acceptance and Commitment Therapy (ACT) to foster self-care and reduce stress in mental health professionals. Twenty-four quantitative articles from PsycInfo and PubMed were identified that focused on mindfulness, self-compassion, psychological flexibility, stress, burnout, or psychological well-being. All MBSR and MBCT studies lacked active control conditions, but some of the ACT studies and one MSC study included an active control. Most studies support evidence that all training programs tend to improve mindfulness and some also self-compassion. In addition, psychological flexibility was measured in …

Self-Stigma And Weight Loss: The Impact Of Fear Of Being Stigmatized, Jason Lillis, J. G. Thomas, Michael E. Levin, R. R. Wing

Psychology Faculty Publications

The current study sought to examine whether two facets of weight self-stigma (fear of enacted stigma and self-devaluation) were associated with weight change and treatment engagement for 188 individuals participating in a 3-month online weight loss program. Fear of enacted stigma predicted less weight loss 3-months later after controlling for demographics, eating problems, and psychological symptoms. Self-devaluation did not predict weight loss. Neither weight self-stigma variable predicted engagement in the online program. These results add to the literature indicating the negative effects of weight self-stigma while highlighting the central role of fear of being stigmatized by others in this process.

Impaired Latent Inhibition In Gdnf-Deficient Mice Exposed To Chronic Stress, Mona Buhusi, Colten K. Brown, Catalin V. Buhusi

Psychology Faculty Publications

Increased reactivity to stress is maladaptive and linked to abnormal behaviors and psychopathology. Chronic unpredictable stress (CUS) alters catecholaminergic neurotransmission and remodels neuronal circuits involved in learning, attention and decision making. Glial-derived neurotrophic factor (GDNF) is essential for the physiology and survival of dopaminergic neurons in substantia nigra and of noradrenergic neurons in the locus coeruleus. Up-regulation of GDNF expression during stress is linked to resilience; on the other hand, the inability to up-regulate GDNF in response to stress, as a result of either genetic or epigenetic modifications, induces behavioral alterations. For example, GDNF-deficient mice exposed to chronic stress exhibit …

Picture This: Using Photo-Research Exhibits As Science Outreach, Eden J.V. Hennessey, Mindi D. Foster, Shohini Ghose

Psychology Faculty Publications

Is a picture worth a thousand words? This paper discusses a unique science outreach initiative–provocative photo-research exhibits on sexism in science.

Gender imbalance in science, technology, engineering, and math (STEM) is not only a concern from a social justice perspective, but also has negative consequences for scientific innovation and the economy, given that lack of workplace gender diversity is associated with lower revenue and returns. Science outreach (i.e., public outreach by scientists) could be particularly impactful in Waterloo, Ontario – a region known as ‘Canada’s Silicon Valley’ that contributes over $30-billion annually to the global economy. Portraying complex social issues …

Psychosocial Functioning And The Cortisol Awakening Response: Meta-Analysis, P-Curve Analysis, And Evaluation Of The Evidential Value In Existing Studies, Ian Andres Boggero, Camelia E. Hostinar, Eric A. Haak, Michael L. M. Murphy, Suzanne C. Segerstrom

Psychology Faculty Publications

Cortisol levels rise immediately after awakening and peak approximately 30-45 minutes thereafter. Psychosocial functioning influences this cortisol awakening response (CAR), but there is considerable heterogeneity in the literature. The current study used p-curve and metaanalysis on 709 findings from 212 studies to test the evidential value and estimate effect sizes of four sets of findings: those associating worse psychosocial functioning with higher or lower cortisol increase relative to the waking period (CARi) and to the output of the waking period (AUCw). All four sets of findings demonstrated evidential value. Psychosocial predictors explained 1%-3.6% of variance in CARi and AUCw …

High Trait Shame Undermines The Protective Effects Of Prevalence Knowledge On State Shame Following Hpv/Cin Diagnosis In Women, Sarah Mcqueary Flynn, Tory A. Eisenlohr-Moul, Suzanne C. Segerstrom, Christen T. Logue, Jamie L. Studts

Psychology Faculty Publications

Human papillomavirus (HPV), and the related, cervical intraepithelial neoplasia (CIN), are common yet poorly understood physical conditions. The diagnosis of HPV often elicits shame and guilt, which in turn may undermine psychological and physical health. The current study compared shame and guilt responses to diagnosis among two groups: women diagnosed with HPV/CIN and women diagnosed with Epstein–Barr Virus (EBV/IM). Eighty women recently diagnosed with HPV/CIN or EBV/IM completed measures of shame- and guilt-proneness, shame and guilt following diagnosis, and disease knowledge including prevalence estimates (HPV and EBV, respectively). HPV/CIN (vs. EBV/IM) predicted more diagnosis-related shame and guilt. Estimates of high …

Psycho-Ecological Systems Model: A Systems Approach To Planning And Gauging The Community Impact Of Community-Engaged Scholarship, Roger N. Reeb, Nyssa L. Snow-Hill, Susan F. Folger, Anne L. Steel, Laura Stayton, Charles Hunt, Bernadette O’Koon, Zachary Glendening

Psychology Faculty Publications

This article presents the Psycho-Ecological Systems Model (PESM) – an integrative conceptual model rooted in General Systems Theory (GST). PESM was developed to inform and guide the development, implementation, and evaluation of transdisciplinary (and multilevel) community-engaged scholarship (e.g., a participatory community action research project undertaken by faculty that involves graduate and/or undergraduate students as service-learning research assistants). To set the stage, the first section critiques past conceptual models. Following a description of GST, the second section provides a comprehensive description of PESM, which represents an integration of three conceptual developments: the ecological systems model (Bronfenbrenner, 1979), the biopsychosocial model (Kiesler, …

Self-Compassion, Self-Injury, And Pain, Wesley Ellen Gregory, Jillian V. Glazer, Kathy R. Berenson

Psychology Faculty Publications

We conducted an experiment to examine self-compassion and responses to pain among undergraduate women with and without histories of self-injury. After a writing task that has been shown to increase self-compassion in a values-affirming condition relative to a neutral control condition, participants completed a self-report measure of state self-compassion and the cold pressor task. As predicted, participants with a history of self-injury reported lower trait self-compassion than those without such a history, and participants in the values-affirming condition reported significantly higher state self-compassion than those in the control condition. Moreover, participants with a history of self-injury demonstrated significantly less insensitivity …

Positive Facial Affect Looks Healthy, Alex L. Jones, Carlota Batres, Aurélie Porcheron, Jennifer R. Sweda, Frédérique Morizot, Richard Russell

Psychology Faculty Publications

A healthy appearance is linked to important behavioural outcomes. Here we investigated whether positive facial affect is a cue for perceived health. In study one, two groups of participants rated the perceived health or perceived happiness of a large set of faces with neutral expressions. Perceived happiness predicted perceived health, as did anthropometric measures of expression. In a second experimental study, we collected ratings of perceived health for a wide age range of target faces with either neutral or smiling expressions. Smiling faces were rated as being much healthier looking than neutral faces, confirming that facial expression plays a role …
