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

Higher And Lower Order Factor Analyses Of The Temperament In Middle Childhood Questionnaire., Yuliya Kotelnikova, Thomas M Olino, Daniel N Klein, Sarah V M Mackrell, Elizabeth P Hayden
Brain and Mind Institute Researchers' Publications
The Temperament in Middle Childhood Questionnaire (TMCQ) is a widely used parent-report measure of temperament. However, neither its lower nor higher order structures has been tested via a bottom-up, empirically based approach. We conducted higher and lower order exploratory factor analyses (EFAs) of the TMCQ in a large ( N = 654) sample of 9-year-olds. Item-level EFAs identified 92 items as suitable (i.e., with loadings ≥.40) for constructing lower order factors, only half of which resembled a TMCQ scale posited by the measure's authors. Higher order EFAs of the lower order factors showed that a three-factor structure (Impulsivity/Negative Affectivity, Negative …
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
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 …

Two thirds of patients were women and three quarters were white. The most common International Classification of …
Hair Cortisol As A Biomarker Of Stress In Mindfulness Training For Smokers., Simon B Goldberg, Alison R Manley, Stevens S Smith, Jeffrey M Greeson, Evan Russell, Stan Van Uum, Gideon Koren, James M Davis
Hair Cortisol As A Biomarker Of Stress In Mindfulness Training For Smokers., Simon B Goldberg, Alison R Manley, Stevens S Smith, Jeffrey M Greeson, Evan Russell, Stan Van Uum, Gideon Koren, James M Davis
Jeffrey M. Greeson
OBJECTIVES: Stress is a well-known predictor of smoking relapse, and cortisol is a primary biomarker of stress. The current pilot study examined changes in levels of cortisol in hair within the context of two time-intensity matched behavioral smoking cessation treatments: mindfulness training for smokers and a cognitive-behavioral comparison group. PARTICIPANTS: Eighteen participants were recruited from a larger randomized controlled trial of smoking cessation. OUTCOME MEASURES: Hair samples (3 cm) were obtained 1 month after quit attempt, allowing for a retrospective analysis of hair cortisol at preintervention and post-quit attempt time periods. Self-reported negative affect was also assessed before and after …
A Narrative Review Of Yoga And Mindfulness As Complementary Therapies For Addiction., Surbhi Khanna, Jeffrey M Greeson
A Narrative Review Of Yoga And Mindfulness As Complementary Therapies For Addiction., Surbhi Khanna, Jeffrey M Greeson
Jeffrey M. Greeson
This paper reviews the philosophical origins, current scientific evidence, and clinical promise of yoga and mindfulness as complementary therapies for addiction. Historically, there are eight elements of yoga that, together, comprise ethical principles and practices for living a meaningful, purposeful, moral and self-disciplined life. Traditional yoga practices, including postures and meditation, direct attention toward one's health, while acknowledging the spiritual aspects of one's nature. Mindfulness derives from ancient Buddhist philosophy, and mindfulness meditation practices, such as gentle Hatha yoga and mindful breathing, are increasingly integrated into secular health care settings. Current theoretical models suggest that the skills, insights, and self-awareness …
Changes In Spirituality Partly Explain Health-Related Quality Of Life Outcomes After Mindfulness-Based Stress Reduction., Jeffrey M Greeson, Daniel M Webber, Moria J Smoski, Jeffrey G Brantley, Andrew G Ekblad, Edward C Suarez, Ruth Quillian Wolever
Changes In Spirituality Partly Explain Health-Related Quality Of Life Outcomes After Mindfulness-Based Stress Reduction., Jeffrey M Greeson, Daniel M Webber, Moria J Smoski, Jeffrey G Brantley, Andrew G Ekblad, Edward C Suarez, Ruth Quillian Wolever
Jeffrey M. Greeson
Mindfulness-Based Stress Reduction is a secular behavioral medicine program that has roots in meditative spiritual practices. Thus, spirituality may partly explain Mindfulness-Based Stress Reduction outcomes. Participants (N = 279; M (SD) age = 45(12); 75% women) completed an online survey before and after an 8-week Mindfulness-Based Stress Reduction program. Structural equation modeling was used to test the hypothesis that, following Mindfulness-Based Stress Reduction, the relationship between enhanced mindfulness and improved health-related quality of life is mediated by increased daily spiritual experiences. Changes in both spirituality and mindfulness were significantly related to improvement in mental health. Although the initial mediation hypothesis …

A Randomized Controlled Trial Of Koru: A Mindfulness Program For College Students And Other Emerging Adults., Jeffrey M Greeson, Michael K Juberg, Margaret Maytan, Kiera James, Holly Rogers
Jeffrey M. Greeson
OBJECTIVE: To evaluate the effectiveness of Koru, a mindfulness training program for college students and other emerging adults. PARTICIPANTS: Ninety students (66% female, 62% white, 71% graduate students) participated between Fall 2012 and Spring 2013. METHODS: Randomized controlled trial. It was hypothesized that Koru, compared with a wait-list control group, would reduce perceived stress and sleep problems, and increase mindfulness, self-compassion, and gratitude. RESULTS: As hypothesized, results showed significant Group (Koru, Wait-List)×Time (Pre, Post) interactions for improvements in perceived stress (F[1, 76.40]=4.50, p=.037, d=.45), sleep problems (F [1, 79.49]=4.71, p=.033, d=.52), mindfulness (F [1, 79.09]=26.80, p CONCLUSIONS: Results support the …

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 …

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 …
Vocabulary Learning Benefits From Rem After Slow-Wave Sleep., Laura J Batterink, Carmen E Westerberg, Ken A Paller
Vocabulary Learning Benefits From Rem After Slow-Wave Sleep., Laura J Batterink, Carmen E Westerberg, Ken A Paller
Brain and Mind Institute Researchers' Publications
Memory reactivation during slow-wave sleep (SWS) influences the consolidation of recently acquired knowledge. This reactivation occurs spontaneously during sleep but can also be triggered by presenting learning-related cues, a technique known as targeted memory reactivation (TMR). Here we examined whether TMR can improve vocabulary learning. Participants learned the meanings of 60 novel words. Auditory cues for half the words were subsequently presented during SWS in an afternoon nap. Memory performance for cued versus uncued words did not differ at the group level but was systematically influenced by REM sleep duration. Participants who obtained relatively greater amounts of REM showed a …

Cross-Lagged Relations Between Motives And Substance Use: Can Use Strengthen Your Motivation Over Time?, Christine A. Lee, Karen J Derefinko, Heather A. Davis, Richard S. Milich, Donald R. Lynam
Psychology Faculty Publications
Motives for substance use have garnered considerable attention due to the strong predictive utility of this construct, both in terms of use and problems associated with use. The current study examined the cross-lagged relations between alcohol use and motives, and marijuana use and motives over three yearly assessment periods in a large sample (N = 526, 48% male) of college students. The relations between substance use and motives were assessed at each time point, allowing for the examination of these inter-relations over time. Results indicated different trends based on the type of substance. For alcohol use, cross-lagged trends were …

A Longitudinal Study Of The Reciprocal Relationship Between Ever Smoking And Urgency In Early Adolescence, Jessica L. Burris, Elizabeth N. Riley, Gabriella E. Puleo, Gregory T. Smith
Psychology Faculty Publications
Background—Among early adolescents in the United States (U.S.), the prevalence of cigarette smoking is at its lowest level in recent decades. Nonetheless, given the risks of smoking in early development, it remains critically important to study both risk factors for smoking and risks from smoking. This longitudinal study with U.S. early adolescents examines smoking initiation and tests a model of reciprocal prediction between ever smoking and the personality trait of urgency (i.e., mood-based impulsivity), a trait that increases risk for multiple forms of dysfunction.
Methods—Participants (n=1906; 90% 10–11 years old, 50% female, 39% racial minorities at …

The ability to mentalize has been marked as an important cognitive mechanism enabling belief in supernatural agents. In five studies we cross-culturally investigated the relationship between mentalizing and belief in supernatural agents with large sample sizes (over 67,000 participants in total) and different operationalizations of mentalizing. The relative importance of mentalizing for endorsing supernatural beliefs was directly compared with credibility enhancing displays–the extent to which people observed credible religious acts during their upbringing. We also compared autistic with neurotypical adolescents. The empathy quotient and the autism-spectrum quotient were not predictive of belief in supernatural agents in all countries (i.e., The …

An Initial Application Of A Biopsychosocial Framework To Predict Posttraumatic Stress Following Pediatric Injury, Meghan L. Marsac, Nancy Kassam-Adams, Douglas L. Delahanty, Jeffrey Ciesla, Danielle Weiss, Keith F. Widaman, Lamia P. Barakat
Pediatrics Faculty Publications
Objectives—Each year millions of children suffer from unintentional injuries that result in poor emotional and physical health. This study examined selected biopsychosocial factors (i.e., child heart rate, peritrauma appraisals, early coping, trauma history) to elucidate their roles in promoting emotional recovery following injury. The study evaluated specific hypotheses that threat appraisals (global and trauma-specific) and coping would predict subsequent posttraumatic stress symptoms (PTSS), that coping would mediate the association between early and later PTSS, and that heart rate would predict PTSS and appraisals would mediate this association.
Method—Participants were 96 children hospitalized for injury and assessed at 3 …

Individual differences in dimensions of impulsivity personality including disinhibition and sensation seeking modulate approach responses to reinforcing stimuli, such as drugs and money. The current study examined the effects of monetary incentive on both behavioral performance and electrophysiological activity among individuals varying in disinhibition and sensation seeking. The monetary incentive delay (MID) task was completed under electroencephalogram (EEG) recording. Behavioral data showed that higher disinhibition and sensation-seeking were associated with lower performance accuracy. Event-related potential (ERP) data showed that high reinforcement cues elicited a larger late positive component (LPC) than other conditions among high disinhibition participants, indicating its strong emotional …

Ethnic identity is an important buffer against drug use among minority youth. However, limited work has examined pathways through which ethnic identity mitigates risk. School-aged youth (N = 34,708; 52 % female) of diverse backgrounds (i.e., African American (n = 5333), Asian (n = 392), Hispanic (n = 662), Multiracial (n = 2129), Native American (n = 474), and White (n = 25718) in grades 4–12 provided data on ethnic identity, drug attitudes, and drug use. After controlling for gender and grade, higher ethnic identity was associated with lower past month drug use …

Introduction—Nicotine dependence is a chronic disorder often characterized by multiple failed quit attempts (QAs). Yet, little is known about the sequence of methods used across multiple QAs or how this may impact future ability to abstain from smoking. This prospective cohort study examines the effectiveness of switching smoking-cessation medications (SCMs) across multiple QAs.
Methods—Adult smokers (aged ≥ 18 years) participating in International Tobacco Control surveys in the United Kingdom, U.S., Canada, and Australia (N=795) who: (1) completed two consecutive surveys between 2006 and 2011; (2) initiated a QA at least 1 month before each survey; and (3) provided …

Social Rejection Magnifies Impulsive Behavior Among Individuals With Greater Negative Urgency: An Experimental Test Of Urgency Theory, David S. Chester, Donald R. Lynam, Richard S. Milich, C. Nathan Dewall
Psychology Faculty Publications
Impulsivity is a multifaceted trait with substantial implications for human well-being. One facet of impulsivity is negative urgency, the tendency to act impulsively in response to negative affect. Correlational evidence suggests that negative affect magnifies impulsive behavior among individuals with greater negative urgency, yet causal evidence for this core pillar of urgency theory is lacking. To fill this gap in the literature, participants (N = 363) were randomly assigned to experience social rejection (a situation shown to induce negative affect) or acceptance. Participants then reported their subjective negative affect, completed a behavioral measure of impulsivity, and reported their negative …
Rapid Statistical Learning Supporting Word Extraction From Continuous Speech., Laura J Batterink
Rapid Statistical Learning Supporting Word Extraction From Continuous Speech., Laura J Batterink
Brain and Mind Institute Researchers' Publications
The identification of words in continuous speech, known as speech segmentation, is a critical early step in language acquisition. This process is partially supported by statistical learning, the ability to extract patterns from the environment. Given that speech segmentation represents a potential bottleneck for language acquisition, patterns in speech may be extracted very rapidly, without extensive exposure. This hypothesis was examined by exposing participants to continuous speech streams composed of novel repeating nonsense words. Learning was measured on-line using a reaction time task. After merely one exposure to an embedded novel word, learners demonstrated significant learning effects, as revealed by …

Unique Prediction Of Cannabis Use Severity And Behaviors By Delay Discounting And Behavioral Economic Demand, Justin C. Strickland, Joshua A. Lile, William W. Stoops
Psychology Faculty Publications
Few studies have simultaneously evaluated delay discounting and behavioral economic demand to determine their unique contribution to drug use. A recent study in cannabis users found that monetary delay discounting uniquely predicted cannabis dependence symptoms, whereas cannabis demand uniquely predicted use frequency. This study sought to replicate and extend this research by evaluating delay discounting and behavioral economic demand measures for multiple commodities and including a use quantity measure. Amazon.com’s Mechanical Turk was used to sample individuals reporting recent cannabis use (n = 64) and controls (n = 72). Participants completed measures of monetary delay discounting as well as alcohol …
Laboratory Analysis Of Risky Driving At 0.05% And 0.08% Blood Alcohol Concentration, Nicholas A. Van Dyke, Mark T. Fillmore
Laboratory Analysis Of Risky Driving At 0.05% And 0.08% Blood Alcohol Concentration, Nicholas A. Van Dyke, Mark T. Fillmore
Psychology Faculty Publications
Background—The public health costs associated with alcohol-related traffic crashes are a continuing problem for society. One harm reduction strategy has been to employ per se limits for blood alcohol concentrations (BACs) at which drivers can legally operate motor vehicles. This limit is currently 0.08% in all 50 US states. Recently, the National Transportation Safety Board proposed lowering the legal limit to 0.05 % (NTSB, 2013). While research has well-validated the ability of alcohol to impair driving performance and heighten crash-risk at these BACs, relatively little is known about the degree to which alcohol might increase drivers’ risk-taking.
Methods—Risk-taking …

Neurophysiological Capacity In A Working Memory Task Differentiates Dependent From Nondependent Heavy Drinkers And Controls, Michael J. Wesley, Joshua A. Lile, Mark T. Fillmore, Linda J. Porrino
Behavioral Science Faculty Publications
Background—Determining the brain-behavior profiles that differentiate heavy drinkers who are and are not alcohol dependent will inform treatment efforts. Working memory is linked to substance use disorders and can serve as a representation of the demand placed on the neurophysiology associated with cognitive control.
Methods—Behavior and brain activity (via fMRI) were recorded during an N-Back working memory task in controls (CTRL), nondependent heavy drinkers (A-ND) and dependent heavy drinkers (A-D). Typical and novel step-wise analyses examined profiles of working memory load and increasing task demand, respectively.
Results—Performance was significantly decreased in A-D during high working memory load …

Young women who regularly attend nightclubs are at risk for numerous health and social consequences, including mental distress, sexual and physical victimization and substance dependence. This paper uses a biopsychosocial framework to examine co-occurring mental health problems, victimization, substance dependence, sexual risk and physical pain among a sample of young women who use drugs (N = 222) in Miami’s club scene. The majority of women were under 24 years old, Hispanic, and identified as heterosexual. Almost all the women reported past 90-day use of alcohol, ecstasy/MDMA, marijuana, cocaine and prescription opioids and benzodiazepines; 32% of women reported being in a …

Brain and Mind Institute Researchers' Publications
Individuals born without one hand (congenital one-handers) provide a unique model for understanding the relationship between focal reorganization in the sensorimotor cortex and everyday behavior. We previously reported that the missing hand's territory of one-handers becomes utilized by its cortical neighbor (residual arm representation), depending on residual arm usage in daily life to substitute for the missing hand's function [1, 2]. However, the repertoire of compensatory behaviors may involve utilization of other body parts that do not cortically neighbor the hand territory. Accordingly, the pattern of brain reorganization may be more extensive [3]. Here we studied unconstrained compensatory strategies under …

Odd Symptom Network During Preschool, Tess E. Smith, Christine A. Lee, Michelle M. Martel, Marni E. Axelrad
Psychology Faculty Publications
Several different conceptualizations of Oppositional Defiant Disorder (ODD) symptoms have been proposed, including one undivided set of symptoms (DSM-IV-TR; APA 2000); two domains of symptoms subdivided into affective and behavioral; and three domains of symptoms subdivided as angry/irritable, argumentative/defiant, and spiteful. The current study utilizes a novel approach to examining the division of ODD symptoms through use of network analysis. Participants were 109 preschoolers (64 male) between the ages of three and six (M = 4.34 years, SD = 1.08) and their parents and teachers/caregivers, who provided ratings of ODD symptoms. Results are consistent with one-, two-, and three- …

Sensory Processing In Autism Spectrum Disorders And Fragile X Syndrome-From The Clinic To Animal Models., D Sinclair, B Oranje, K A Razak, S J Siegel, S Schmid
Brain and Mind Institute Researchers' Publications
Brains are constantly flooded with sensory information that needs to be filtered at the pre-attentional level and integrated into endogenous activity in order to allow for detection of salient information and an appropriate behavioral response. People with Autism Spectrum Disorder (ASD) or Fragile X Syndrome (FXS) are often over- or under-reactive to stimulation, leading to a wide range of behavioral symptoms. This altered sensitivity may be caused by disrupted sensory processing, signal integration and/or gating, and is often being neglected. Here, we review translational experimental approaches that are used to investigate sensory processing in humans with ASD and FXS, and …

Online Neural Monitoring Of Statistical Learning., Laura J Batterink, Ken A Paller
Brain and Mind Institute Researchers' Publications
The extraction of patterns in the environment plays a critical role in many types of human learning, from motor skills to language acquisition. This process is known as statistical learning. Here we propose that statistical learning has two dissociable components: (1) perceptual binding of individual stimulus units into integrated composites and (2) storing those integrated representations for later use. Statistical learning is typically assessed using post-learning tasks, such that the two components are conflated. Our goal was to characterize the online perceptual component of statistical learning. Participants were exposed to a structured stream of repeating trisyllabic nonsense words and a …
Sleep-Based Memory Processing Facilitates Grammatical Generalization: Evidence From Targeted Memory Reactivation., Laura J Batterink, Ken A Paller
Sleep-Based Memory Processing Facilitates Grammatical Generalization: Evidence From Targeted Memory Reactivation., Laura J Batterink, Ken A Paller
Brain and Mind Institute Researchers' Publications
Generalization-the ability to abstract regularities from specific examples and apply them to novel instances-is an essential component of language acquisition. Generalization not only depends on exposure to input during wake, but may also improve offline during sleep. Here we examined whether targeted memory reactivation during sleep can influence grammatical generalization. Participants gradually acquired the grammatical rules of an artificial language through an interactive learning procedure. Then, phrases from the language (experimental group) or stimuli from an unrelated task (control group) were covertly presented during an afternoon nap. Compared to control participants, participants re-exposed to the language during sleep showed larger …
