Beyond Perceptual Expertise: Revisiting The Neural Substrates Of Expert Object Recognition, Assaf Harel, Dwight J. Kravitz, Chris I. Baker

Psychology Faculty Publications

Real-world expertise provides a valuable opportunity to understand how experience shapes human behavior and neural function. In the visual domain, the study of expert object recognition, such as in car enthusiasts or bird watchers, has produced a large, growing, and often-controversial literature. Here, we synthesize this literature, focusing primarily on results from functional brain imaging, and propose an interactive framework that incorporates the impact of high-level factors, such as attention and conceptual knowledge, in supporting expertise. This framework contrasts with the perceptual view of object expertise that has concentrated largely on stimulus-driven processing in visual cortex. One prominent version of …

Reduced Neural Activation During An Inhibition Task Is Associated With Impaired Fear Inhibition In A Traumatized Civilian Sample, Tanja Jovanovic, Tim Ely, Negar Fani, Ebony Glover, David Gutman, Erin Tone, Seth D. Norrholm, Bekh Bradley, Kerry J. Ressler

Psychology Faculty Publications

Introduction: Impaired inhibition of fear in the presence of safety cues and a deficiency in the extinction of fear cues are increasingly thought to be important biological markers of Posttraumatic Stress Disorder (PTSD). Other studies have suggested that there may be altered neural activation during behavioral inhibition tasks in subjects with PTSD. The current study aimed to see whether neural activation during inhibition was reduced in a highly traumatized civilian population, and whether atypical activation was associated with impaired fear inhibition.

Methods: The participants were 41 traumatized women (20 PTSD+, 21 PTSD-) recruited from Grady Memorial Hospital in …

A Theory-Driven, Longitudinal Evaluation Of The Impact Of Team Training On Safety Culture In 24 Hospitals, Katherine J. Jones, Anne M. Skinner, Robin High, Roni Reiter-Palmon

Psychology Faculty Publications

Effective teamwork facilitates collective learning, which is integral to safety culture. There are no rigorous evaluations of the impact of team training on the four components of safety culture—reporting, just, flexible and learning cultures. We evaluated the impact of a year-long team training programme on safety culture in 24 hospitals using two theoretical frameworks.

Fkbp5 Modulates Attention Bias For Threat: Associations With Hippocampal Function And Morphology, Negar Fani, David Gutman, Erin Tone, Lynn Almli, Kristina B. Mercer, Jennifer Davis, Ebony Glover, Tanja Jovanovic, Bekh Bradley, Ivo D. Dinov, Alen Zamanyan, Arthur W. Toga, Elisabeth B. Binder, Kerry J. Ressler

Psychology Faculty Publications

Context: The FKBP5 gene product regulates glucocorticoid receptor (GR) sensitivity and hypothalamicpituitary‐adrenal axis functioning, and has been associated with a number of stress‐related psychiatric disorders. The study of intermediate phenotypes, such as emotion‐processing biases and their neural substrates, provides a way to clarify the mechanisms by which FKBP5 dysregulation mediates psychopathology risk.

Objective: To examine whether allelic variations for a putatively functional SNP associated with FKBP5 gene regulation (rs1360780) would relate differentially to attentional bias for threat; this was measured through behavioral response on a dot probe task and hippocampal activation during task performance. Morphological substrates of differential hippocampal response …

Predictive Effects Of Good Self-Control And Poor Regulation On Alcohol-Related Outcomes: Do Protective Behavioral Strategies Mediate?, Matthew R. Pearson, Benjamin A. Kite, James M. Henson

Psychology Faculty Publications

In the present study, we examined whether use of protective behavioral strategies mediated the relationship between self-control constructs and alcohol-related outcomes. According to the two-mode model of self-control, good self-control (planfulness; measured with Future Time Perspective, Problem Solving, and Self-Reinforcement) and poor regulation (impulsivity; measured with Present Time Perspective, Poor Delay of Gratification, Distractibility) are theorized to be relatively independent constructs rather than opposite ends of a single continuum. The analytic sample consisted of 278 college student drinkers (68% women) who responded to a battery of surveys at a single time point. Using a structural equation model based on the …

Impulsivity Like Traits And Risky Driving Behaviors Among College Students, Matthew R. Pearson, Elaine M. Murphy, Ashley N. Doane

Psychology Faculty Publications

The present study examined the predictive effects of five impulsivity-like traits (Premeditation, Perseverance, Sensation Seeking, Negative Urgency, and Positive Urgency) on driving outcomes (driving errors, driving lapses, driving violations, cell phone driving, traffic citations, and traffic collisions). With a convenience sample of 266 college student drivers, we found that each of the impulsivity-like traits was related to multiple risky driving outcomes. Positive Urgency (tendency to act impulsively when experiencing negative affect) was the most robust predictor of risky driving outcomes. Positive Urgency is a relatively newly conceptualized impulsivity-like trait that was not examined in the driving literature previously, suggesting a …

Developmental Changes In Postural Stability During The Performance Of A Precision Manual Task, Jeffrey M. Haddad, Laura J. Claxton, Dawn Melzer, Joseph Hamill, Richard E. A. Van Emmerik

Psychology Faculty Publications

Posture becomes integrated with other goal-directed behaviors early in infancy and continues to develop into the second decade of life. However, the developmental time course over which posture is stabilized relative to the base of support during a dynamic manual precision task has not been examined. Postural-manual integration was assessed in 7-year-olds, 10-year-olds, and adults using a postural-manual task in which task precision (target fitting size) and postural difficulty (reaching distance to a target) were manipulated. The main dependent variable was postural time-to-contact (TtC). Results indicated systematic age effects in which TtC was shortest in the 7-year-olds, increased in the …

Unplanned Drinking And Alcohol-Related Problems: A Preliminary Test Of The Model Of Unplanned Drinking Behavior, Matthew R. Pearson, James M. Henson

Psychology Faculty Publications

Much research links impulsivity with alcohol use and problems. In 2 studies, unplanned (or impulsive) drinking is assessed directly to determine whether it has direct effects on alcohol use and alcohol-related problems. In Study 1, we examined whether unplanned drinking serves as a proximal mediator of the effects of impulsivity-like traits on alcohol-related outcomes. With a sample of 211 college student drinkers, we found that the Unplanned Drinking Scale was significantly related to alcohol use, and perhaps more important, had a direct effect on alcohol-related problems even after controlling for frequency and quantity of alcohol use. Furthermore, unplanned drinking partially …

Everyday Confrontation Of Discrimination: The Well-Being Costs And Benefits To Women Over Time., Mindi D. Foster

Psychology Faculty Publications

Taking action against discrimination has positive consequences for well-being (e.g., Cocking & Drury, 2004) but most of this research has focused on collective actions and has used methodologies assessing one point in time. This study therefore used a diary methodology to examine how women’s everyday confrontations of discrimination would affect measures of subjective and psychological well-being, and how these relationships would change over time. In a 28-day online diary study, women indicated their daily experience of discrimination, described their response, and completed measures of well-being. Results showed that at the beginning of the study, using indirect confrontation predicted greater well-being …

How Do Interviewers And Children Discuss Individual Occurrences Of Alleged Repeated Abuse In Forensic Interviews?, Sonja P. Brubacher, Lindsay C. Malloy, Michael E. Lamb, Kim Roberts

Psychology Faculty Publications

Police interviews (n = 97) with 5- to 13-year-olds alleging multiple incidents of sexual abuse were examined to determine how interviewers elicited and children recounted specific instances of abuse. Coders assessed the labels for individual occurrences that arose in interviews, recording who generated them, how they were used, and other devices to aid particularisation such as the use of episodic and generic language. Interviewers used significantly more temporal labels than did children. With age, children were more likely to generate labels themselves, but most children generated at least one label. In 66% of the cases, interviewers ignored or replaced …

A Brief Motivational Intervention For Heavy Alcohol Use In Dental Practice Settings: Rationale And Development, James A. Neff, Scott T. Walters, Abby L. Braitman, Michelle L. Kelley, Michele L. Darby, Margaret F. Lemaster

Psychology Faculty Publications

Although brief alcohol interventions have proven effective in a variety of health care settings, the present article describes the development of the first brief intervention for heavy drinkers in dental practice. Elements of motivational interviewing and personalized normative feedback were incorporated in a 3- to 5-minute intervention delivered by dental hygienists. The intervention is guided by a one-page feedback report providing personalized normative feedback regarding the patient's current oral health practices, their drinking in comparison to others, and oral cancer risk associated with current smoking and drinking. Future publications will present data regarding intervention effectiveness from an ongoing randomized trial.

Alcohol Use And Trauma Exposure Among Male And Female Veterans Before, During, And After Military Service, Michelle L. Kelley, Jennifer Runnals, Matthew R. Pearson, Marinell Miller, John A. Fairbank, Va Mid-Atlantic Mirecc Women Veterans Workgroup

Psychology Faculty Publications

Background: The present study examined lifespan and combat-related trauma exposure as predictors of alcohol use among male and female veterans. Posttraumatic stress and depressive symptoms were examined as mediators of the effects of trauma exposure on alcohol use.

Methods: Data were examined from 1825 (1450 male, 375 female) veterans and active duty service members who took part in a multi-site research study conducted through the Department of Veterans Affairs Mid-Atlantic Mental Illness Research, Education and Clinical Center (VISN 6 MIRECC).

Results: For both men and women, depressive symptoms significantly mediated the effects of non-combat trauma exposure experienced before, during and …

The Assessment Of Protective Behavioral Strategies: Comparing The Absolute Frequency And Contingent Frequency Response Scales, Benjamin A. Kite, Matthew R. Pearson, James M. Henson

Psychology Faculty Publications

The purpose of the present studies was to examine the effects of response scale on the observed relationships between protective behavioral strategies (PBS) measures and alcohol-related outcomes. We reasoned that an "absolute frequency" scale (stem: "how many times..."; response scale: 0 times to 11 + times) conflates the frequency of using PBS with the frequency of consuming alcohol; thus, we hypothesized that the use of an absolute frequency response scale would result in positive relationships between types of PBS and alcohol-related outcomes. Alternatively, a "contingent frequency" scale (stem: "When drinking ... how often ..."; response scale: never to always …

Daily Use Of Protective Behavioral Strategies And Alcohol-Related Outcomes Among College Students, Matthew R. Pearson, Gabrielle M. D'Lima, Michelle L. Kelley

Psychology Faculty Publications

The purpose of the present study was to examine associations between use of protective behavioral strategies (PBS) and alcohol-related outcomes (alcohol consumption, negative alcohol consequences, and positive alcohol consequences) using a daily diary approach. This approach is less affected by retrospective memory biases than typical self-reports of alcohol-related variables and allows the examination of both between-subjects and within-person effects. Using hierarchical linear modeling of data from 40 subjects who completed daily dairies for up to 15 days, we found significant within-person variation in PBS use over time, and each type of PBS had unique relationships with alcohol-related outcomes. For example, …
