Perfectionism: The Good, The Bad, And The Creative, Benjamin Wigert, Roni Reiter-Palmon, James C. Kaufman, Paul J. Silvia Dec 2012

Perfectionism: The Good, The Bad, And The Creative, Benjamin Wigert, Roni Reiter-Palmon, James C. Kaufman, Paul J. Silvia

Psychology Faculty Publications

The influence of adaptive and maladaptive perfectionism on creativity was examined. Initially, six measures of creativity were administered, including creative self-perceptions, behavior, and performance measures. Adaptive perfectionism was weakly positively related to creativity, whereas maladaptive perfectionism was unrelated to creativity across five of the six measures. A follow-up study assessed whether initial findings could be generalized to an everyday problem-solving task. Results indicated that adaptive perfectionism was related to higher quality but not originality of solutions. Further, a curvilinear relationship in the shape of an inverted “U” occurred between adaptive perfectionism and four of eight creativity measures. Overall, adaptive perfectionism ...


Identifying And Learning From Exemplary Volunteer Resource Managers: A Look At Best Practices In Managing Volunteer Resources, Amanda M. Backer, Joseph A. Allen, Daniel L. Bonilla Nov 2012

Identifying And Learning From Exemplary Volunteer Resource Managers: A Look At Best Practices In Managing Volunteer Resources, Amanda M. Backer, Joseph A. Allen, Daniel L. Bonilla

Psychology Faculty Publications

Nonprofit organizations thrive to the extent that their volunteer resource manager follows best practices for hiring, training, and managing volunteers. In an effort to identify some of the best practices in volunteer management, exemplary volunteer resources managers were identified from a consulting outreach program. These managers were then interviewed and the results from these interviews are presented here. Volunteer resource managers shared their best practices for improving volunteer organizational commitment, organizational recognition of volunteers, volunteer satisfaction with communication, volunteer perception of voice, volunteer competence & volunteer contribution, and volunteer burnouts & intentions to quit. In addition to presenting these practices, commentary includes ...


Antenatal Physical Activity Counseling Among Healthcare Providers, Jenn Leiferman, Margaret Gutilla, James Paulson, Jim Pivarnik Nov 2012

Antenatal Physical Activity Counseling Among Healthcare Providers, Jenn Leiferman, Margaret Gutilla, James Paulson, Jim Pivarnik

Psychology Faculty Publications

Objective: Pregnant women often report a lack of knowledge concerning the safety of exercising during pregnancy. Healthcare providers play an integral role in providing pregnant women with the necessary knowledge to promote antenatal physical activity. Thus, the objective of this study was to assess healthcare providers’ beliefs, attitudes, knowledge and practices related to antenatal physical activity counseling.

Study Design: 188 Providers (i.e. obstetricians, midwives, and family medicine physicians) completed a 39 closed-item survey. Characteristics among healthcare providers’ physical activity counseling practices as well as belief, attitudes and knowledge were explored.

Results: The majority of all providers agreed that physical ...


Cocaine-Induced Reinstatement Of A Conditioned Place Preference In Developing Rats: Involvement Of The D2 Receptor, Kimberly A. Badanich, Cheryl L. Kirstein Oct 2012

Cocaine-Induced Reinstatement Of A Conditioned Place Preference In Developing Rats: Involvement Of The D2 Receptor, Kimberly A. Badanich, Cheryl L. Kirstein

Psychology Faculty Publications

Reinstatement of conditioned place preferences have been used to investigate physiological mechanisms mediating drug-seeking behavior in adolescent and adult rodents; however, it is still unclear how psychostimulant exposure during adolescence affects neuron communication and whether these changes would elicit enhanced drug-seeking behavior later in adulthood. The present study determined whether the effects of intra-ventral tegmental area (VTA) or intra-nucleus accumbens septi (NAcc) dopamine (DA) D2 receptor antagonist infusions would block (or potentiate) cocaine-induced reinstatement of conditioned place preferences. Adolescent rats (postnatal day (PND 28–39)) were trained to express a cocaine place preference. The involvement of D2 receptors on cocaine-induced ...


Statistical Measures For Workload Capacity Analysis, Joseph W. Houpt, James T. Townsend Oct 2012

Statistical Measures For Workload Capacity Analysis, Joseph W. Houpt, James T. Townsend

Psychology Faculty Publications

A critical component of how we understand a mental process is given by measuring the effect of varying the workload. The capacity coefficient (Townsend and Nozawa, 1995 and Townsend and Wenger, 2004) is a measure on response times for quantifying changes in performance due to workload. Despite its precise mathematical foundation, until now rigorous statistical tests have been lacking. In this paper, we demonstrate statistical properties of the components of the capacity measure and propose a significance test for comparing the capacity coefficient to a baseline measure or two capacity coefficients to each other.


American Men’S And Women’S Beliefs About Gender Discrimination: For Men, It’S Not Quite A Zerosum Game, Jennifer K. Bosson, Joseph A. Vandello, Kenneth S. Michniewicz, Joshua G. Lenes Oct 2012

American Men’S And Women’S Beliefs About Gender Discrimination: For Men, It’S Not Quite A Zerosum Game, Jennifer K. Bosson, Joseph A. Vandello, Kenneth S. Michniewicz, Joshua G. Lenes

Psychology Faculty Publications

We surveyed Americans regarding their beliefs about gender discrimination over the past several decades. Men and women agreed that women faced much more discrimination than men in the past, and they agreed that the discrimination gap between men and women has narrowed in recent years. However, men perceived the gap as narrower than women did at all time periods, and reported that there is little difference today in the amount of gender discrimination women and men face. Political ideology moderated these beliefs such that conservative men were most likely to report that anti-Man bias now equals or exceeds anti-Woman bias ...


An Examination Of Exposure To Traumatic Events And Symptoms And Strengths For Children Served In A Behavioral Health System Of Care, Melissa L. Whitson, Christian M. Connell, Stanley N. Bernard, Joy S. Kaufman Sep 2012

An Examination Of Exposure To Traumatic Events And Symptoms And Strengths For Children Served In A Behavioral Health System Of Care, Melissa L. Whitson, Christian M. Connell, Stanley N. Bernard, Joy S. Kaufman

Psychology Faculty Publications

The present study examined how exposure to traumatic events impacts children with severe emotional disturbance who are being served in a school-based system of care. Multilevel growth curve models were used to examine the relationships between a child’s history of traumatic events (physical abuse, sexual abuse, or domestic violence) and behavioral and emotional strengths, internalizing problem behaviors, or externalizing problem behaviors over 18 months. Results indicate that children receiving services (N = 134) exhibited increased emotional and behavioral strengths and decreased internalizing and externalizing problem behaviors from enrollment to 18 months follow-up. Children with a history of traumatic events improved ...


The Control Of Posture In Newly Standing Infants Is Task-Dependent, Laura J. Claxton, Dawn Melzer, Jyoong Hyun Ryu, Jeffrey M. Haddad Sep 2012

The Control Of Posture In Newly Standing Infants Is Task-Dependent, Laura J. Claxton, Dawn Melzer, Jyoong Hyun Ryu, Jeffrey M. Haddad

Psychology Faculty Publications

The postural sway patterns of newly standing infants were compared under two conditions: standing while either holding or not holding a toy. Infants exhibited a lower magnitude of postural sway and more complex sway patterns when holding the toy. These changes suggest infants adapt postural sway in a manner that facilitates visually fixating on and stabilizing the toy in their hand. When simply standing, infants exhibited postural sway patterns that appeared to be more exploratory in nature. Exploratory sway patterns may allow infants to learn the affordances of their new standing posture. These results demonstrate newly standing infants are capable ...


Self-Awareness And The Evolution Of Leaders: The Need For A Better Measure Of Self-Awareness, Greg C. Ashley, Roni Reiter-Palmon Sep 2012

Self-Awareness And The Evolution Of Leaders: The Need For A Better Measure Of Self-Awareness, Greg C. Ashley, Roni Reiter-Palmon

Psychology Faculty Publications

A growing body of empirical research suggests that self-awareness is associated with successful leadership. Although self-awareness research has generated a number of scales to measure self-awareness, none have done so with the explicit focus of leadership. The present research is a summary of three studies designed to develop and begin validation for a scale to measure self-awareness in the context of leadership and leader development. The result of Study 1 and 2 was a 54-item self-awareness scale. A confirmatory factor analysis provided evidence for a marginal fit. Predictive validity was assessed in Study 3 by looking for associations between self-awareness ...

The Optimal Calibration Hypothesis: How Life History Modulates The Brain's Social Pain Network, David S. Chester, Richard S. Pond Jr., Stephanie B. Richman, C. Nathan Dewall Jul 2012

The Optimal Calibration Hypothesis: How Life History Modulates The Brain's Social Pain Network, David S. Chester, Richard S. Pond Jr., Stephanie B. Richman, C. Nathan Dewall

Psychology Faculty Publications

A growing body of work demonstrates that the brain responds similarly to physical and social injury. Both experiences are associated with activity in the dorsal anterior cingulate cortex (dACC) and anterior insula. This dual functionality of the dACC and anterior insula underscores the evolutionary importance of maintaining interpersonal bonds. Despite the weight that evolution has placed on social injury, the pain response to social rejection varies substantially across individuals. For example, work from our lab demonstrated that the brain's social pain response is moderated by attachment style: anxious-attachment was associated with greater intensity and avoidant-attachment was associated with less ...


Subtypes Of Attentional Bias Within Social Anxiety Disorder: Evaluating Changes Following Cognitive Behavioral Therapy, Martha R. Calamaras, Erin Tone, Page L. Anderson Jul 2012

Subtypes Of Attentional Bias Within Social Anxiety Disorder: Evaluating Changes Following Cognitive Behavioral Therapy, Martha R. Calamaras, Erin Tone, Page L. Anderson

Psychology Faculty Publications

Prominent theories of social anxiety disorder (SAD) describe the role of attentional bias in the disorder's etiology and maintenance; some models implicate bias toward social threats (e.g., Rapee

& Heimberg, 1997) and others implicate bias to avoid them (e.g., Clark & Wells, 1995). The present

investigation examined: 1) whether a clinical sample of individuals with SAD comprises two distinct groups based on attention bias for social threat (vigilant, avoidant), and 2) group-specific changes in attention bias following cognitive behavioral therapy (CBT) for SAD. Consistent with predictions, results yielded evidence of two pre-treatment groups (vigilant and avoidant). After eight weeks ...


The Political Personality Of 2012 Republican Presidential Candidate Mitt Romney, Aubrey Immelman Jul 2012

The Political Personality Of 2012 Republican Presidential Candidate Mitt Romney, Aubrey Immelman

Psychology Faculty Publications

This paper presents the results of an indirect assessment of the personality of Willard Mitt Romney, Republican presidential candidate in the 2008 U.S. presidential election and Republican presidential nominee in 2012.

The study was conducted in 2007–2008 and 2012, from the conceptual perspective of personologist Theodore Millon. Information concerning Romney was collected from biographical sources and media reports and synthesized into a personality profile using the Millon Inventory of Diagnostic Criteria (MIDC), which yields 34 normal and maladaptive personality classifications congruent with Axis II of DSM–IV.

The personality profile yielded by the MIDC was analyzed on the ...


Color In Context: Psychological Context Moderates The Influence Of Red On Approach- And Avoidance-Motivated Behavior, Brian P. Meier, Paul R. D'Agostino, Andrew J. Elliott, Markus A. Meier, Benjamin M. Wilkowski Jul 2012

Color In Context: Psychological Context Moderates The Influence Of Red On Approach- And Avoidance-Motivated Behavior, Brian P. Meier, Paul R. D'Agostino, Andrew J. Elliott, Markus A. Meier, Benjamin M. Wilkowski

Psychology Faculty Publications

A basic premise of the recently proffered color-in-context model is that the influence of color on psychological functioning varies as a function of the psychological context in which color is perceived. Some research has examined the appetitive and aversive implications of viewing the color red in romance- and achievement-relevant contexts, respectively, but in all existing empirical work approach and avoidance behavior has been studied in separate tasks and separate experiments. Research is needed to directly test whether red influences the same behavior differently depending entirely on psychological context.

The present experiment was designed to put this premise to direct test ...


Is Maternal Smoking During Pregnancy A Causal Environmental Risk Factor For Adolescent Antisocial Behavior? Testing Etiological Theories And Assumptions, Brian M. D'Onofrio, Carol A. Van Hulle, Jackson A. Goodnight, Paul J. Rathouz, Benjamin B. Lahey Jul 2012

Is Maternal Smoking During Pregnancy A Causal Environmental Risk Factor For Adolescent Antisocial Behavior? Testing Etiological Theories And Assumptions, Brian M. D'Onofrio, Carol A. Van Hulle, Jackson A. Goodnight, Paul J. Rathouz, Benjamin B. Lahey

Psychology Faculty Publications

Background—Although many studies indicate that maternal smoking during pregnancy (SDP) is correlated with later offspring antisocial behavior (ASB), recent quasi-experimental studies suggest that background familial factors confound the association. The present study sought to test alternative etiological hypotheses using multiple indices of adolescent ASB, comparing differentially exposed siblings, and testing assumptions in the sibling-comparison design.


Bayesian Approaches To Assessing Architecture And Stopping Rule, Joseph W. Houpt, Andrew Heathcote, Ami Eidels, J. T. Townsend Jul 2012

Bayesian Approaches To Assessing Architecture And Stopping Rule, Joseph W. Houpt, Andrew Heathcote, Ami Eidels, J. T. Townsend

Psychology Faculty Publications

Much of scientific psychology and cognitive science can be viewed as a search to understand the mechanisms and dynamics of perception, thought and action. Two processing attributes of particular interest to psychologists are the architecture, or temporal relationships between sub-processes of the system, and the stopping rule, which dictates how many of the sub-processes must be completed for the system to finish. The Survivor Interaction Contrast (SIC) is a powerful tool for assessing the architecture and stopping rule of a mental process model. Thus far, statistical analysis of the SIC has been limited to null-hypothesis- significance tests. In this talk ...


Correlation Between Facebook Usage And Loneliness And Depression, Jasmine (Chi Man) Tang, Michael Livingston Jun 2012

Correlation Between Facebook Usage And Loneliness And Depression, Jasmine (Chi Man) Tang, Michael Livingston

Psychology Faculty Publications

Facebook has emerged into our society within the last couple years as a powerful social phenomenon. 11.5% of the world population are active users of Facebook while there is a serious lack of psychological theory relating to functions or effects of Facebook. Researchers began realizing the importance of investigating the usage of Facebook and how that might be related to different personality traits. However, not much research has been done on how Facebook use could be related to our social well-beings.

The current study aims to investigate how the use of Facebook influences loneliness and depression. The results showed ...


Cultural Differences In The Levels Of Rewards Between Adolescents From America, Australia, Tanzania, Denmark, Honduras, Korea, And Spain, Kendra J. Homan, Daniel Houlihan, Kari Ek, Joseph Wanzek Jun 2012

Cultural Differences In The Levels Of Rewards Between Adolescents From America, Australia, Tanzania, Denmark, Honduras, Korea, And Spain, Kendra J. Homan, Daniel Houlihan, Kari Ek, Joseph Wanzek

Psychology Faculty Publications

The intent of this study is to determine what items are reinforcing for high school students from different regions of the world including America, Australia, Tanzania, Denmark, Honduras, Korea, and Spain. Additionally, the researchers sought to determine if there is a difference in the levels of rewards between individuals from America and individuals from these other countries. Seven hundred and fifty high school students from seven countries participated in this study. The only requirement for inclusion in the study was current enrollment in high school in their native country. Subject ages ranged from 12 to 19 years, with a mean ...


Evaluation Of Self-Perceptions Of Creativity: Is It A Useful Criterion?, Roni Reiter-Palmon, Erika Morral, James C. Kaufman, Jonathan Bruce Santo Jun 2012

Evaluation Of Self-Perceptions Of Creativity: Is It A Useful Criterion?, Roni Reiter-Palmon, Erika Morral, James C. Kaufman, Jonathan Bruce Santo

Psychology Faculty Publications

Self-evaluations or self-perceptions of creativity have been used in the past both as predictors of creative performance and as a criterion. Four measures utilizing self-perceptions of creativity were assessed for their usefulness as criterion measures of creativity. Analyses provided evidence of domain specificity of self-perceptions. The scales correlated with self-report measures of creativity, but not with objective measures. Self-perceptions of creativity had strong to moderate relationships with personality and creative self-efficacy. These results suggest that while self-perceptions of creativity may provide some information about creativity, researchers should be cautious when using this measure as a criterion.


Shouldering A Silent Burden: The Toll Of Dirty Tasks, Benjamin E. Baran, Steven G. Rogelberg, Erika Carello Lopina, Joseph A. Allen, Christiane Spitzmüller, Mindy Bergman May 2012

Shouldering A Silent Burden: The Toll Of Dirty Tasks, Benjamin E. Baran, Steven G. Rogelberg, Erika Carello Lopina, Joseph A. Allen, Christiane Spitzmüller, Mindy Bergman

Psychology Faculty Publications

Dirty work involves tasks that are stigmatized owing to characteristics that the public finds disgusting, degrading, or objectionable. Conservation of resources theory suggests such experiences should induce strain and decreased work satisfaction; social identity theory suggests such work should lead to strong psychological investment in the work, among other outcomes. Integrating these two perspectives, this study hypothesizes and presents quantitative evidence from 499 animal-shelter workers, demonstrating how dirty-work engagement relates to higher levels of strain, job involvement, and reluctance to discuss work while negatively influencing work satisfaction. Additionally, this study takes a unique perspective on dirty work by focusing on ...


Mediating And Moderating Effects On The Association Between Vision Loss And Depression Among An Older Population, Terry L. Stone, Jonathan Bruce Santo, Walter Wittich May 2012

Mediating And Moderating Effects On The Association Between Vision Loss And Depression Among An Older Population, Terry L. Stone, Jonathan Bruce Santo, Walter Wittich

Psychology Faculty Publications

The purpose of this study was to gain a more holistic view of the association between depression and visual functioning by examining possible mediating and moderating factors. Previous research has established a linkage between low life satisfaction and coping skills and depressive symptoms. Results of this study contribute to this literature by indicating that life satisfaction partially mediates the relationship between visual functioning and depression. Furthermore, a significant coping by visual functioning interaction was discovered, revealing that among this sample, visual impairment is associated with higher levels of depression among individuals with low coping skills; however, little effect was found ...


Binge Eating Disorder Mediates Links Between Symptoms Of Depression And Anxiety And Caloric Intake In Obese Women, Roseann E. Peterson, Shawn J. Latendresse, Lindsay T. Bartholome, Cortney S. Warren, Nancy C. Raymond Apr 2012

Binge Eating Disorder Mediates Links Between Symptoms Of Depression And Anxiety And Caloric Intake In Obese Women, Roseann E. Peterson, Shawn J. Latendresse, Lindsay T. Bartholome, Cortney S. Warren, Nancy C. Raymond

Psychology Faculty Publications

Despite considerable comorbidity between mood disorders, binge eating disorder (BED), and obesity, the underlying mechanisms remain unresolved. Therefore, the purpose of this study was to examine models by which internalizing behaviors of depression and anxiety influence food intake in overweight/obese women. Thirty-two women (15 BED, 17 controls) participated in a laboratory eating-episode and completed questionnaires assessing symptoms of anxiety and depression. Path analysis was used to test mediation and moderation models to determine the mechanisms by which internalizing symptoms influenced kilocalorie (kcal) intake. The BED group endorsed significantly more symptoms of depression (10.1 versus 4.8, P=0 ...


The Impact Of Deliberative Strategy Dissociates Erp Components Related To Conflict Processing Vs. Reinforcement Learning, Christopher M. Warren, Clay B. Holroyd Apr 2012

The Impact Of Deliberative Strategy Dissociates Erp Components Related To Conflict Processing Vs. Reinforcement Learning, Christopher M. Warren, Clay B. Holroyd

Psychology Faculty Publications

We applied the event-related brain potential (ERP) technique to investigate the involvement of two neuromodulatory systems in learning and decision making: The locus coeruleus–norepinephrine system (NE system) and the mesencephalic dopamine system (DA system). We have previously presented evidence that the N2, a negative deflection in the ERP elicited by task-relevant events that begins approximately 200 ms after onset of the eliciting stimulus and that is sensitive to low-probability events, is a manifestation of cortex-wide noradrenergic modulation recruited to facilitate the processing of unexpected stimuli. Further, we hold that the impact of DA reinforcement learning signals on the anterior ...


Drinking To Distraction: Does Alcohol Increase Attentional Bias In Adults With Adhd?, Walter Roberts, Mark T. Fillmore, Richard Milich Apr 2012

Drinking To Distraction: Does Alcohol Increase Attentional Bias In Adults With Adhd?, Walter Roberts, Mark T. Fillmore, Richard Milich

Psychology Faculty Publications

Previous research has shown that social drinkers continue to show attentional bias toward alcohol-related stimuli even after consuming a moderate dose of alcohol. In contrast, little is known about how alcohol acutely affects attentional bias in groups at risk to develop alcohol-related problems, such as adults with attentiondeficit/ hyperactivity disorder (ADHD). Such individuals may show increased attentional bias following alcohol relative to nonclinical controls. The present study tested this hypothesis by examining acute alcohol effects on attentional bias in 20 social drinkers with ADHD and 20 social drinkers with no history of ADHD. Participants performed a visual-probe task after receiving ...


Impressions Of Psychotherapists’ Offices: Do Therapists And Clients Agree?, Ann Sloan Devlin, Jack L. Nasar Apr 2012

Impressions Of Psychotherapists’ Offices: Do Therapists And Clients Agree?, Ann Sloan Devlin, Jack L. Nasar

Psychology Faculty Publications

Do therapists and potential clients similarly evaluate offices of practicing clinicians?Furnishings in a therapist's office can create a welcoming environment, yet little research examines perceptions of such furnishings, leading to the focus of this research. In a previous study with 30 color photographs of psychotherapists' offices, students favored clinical settings that were soft, personalized, and orderly (Nasar & Devlin, 2011). Using the same 30 photographs, the present studies had 32 licensed psychotherapists evaluate the quality of care, comfort in the setting, and therapist qualities they expected clients to experience in each office. The judgments that therapists thought clients would make had high correlations withthe earlier judgments of students; each group's composite evaluation improved significantly as the office became softer and more orderly. This brief report concludes by recommending the features likely to create a welcoming therapeutic office. (PsycINFO Database Record (c) 2012 APA, all rights reserved)

A national survey of 216 school psychologists' perceptions of multicultural competence indicated that multicultural competence significantly increases as a function of hours of training and frequency of experience working with individuals from cultures different from their own. Results are discussed in the context of measurement limitations for multicultural competence and implications for trainers of school psychologists.


On Discriminating Between Geometric Strategies Of Surface-Based Orientation, Bradley R. Sturz, Kent D. Bodily Apr 2012

On Discriminating Between Geometric Strategies Of Surface-Based Orientation, Bradley R. Sturz, Kent D. Bodily

Psychology Faculty Publications

Recently, a debate has manifested in the spatial learning literature regarding the shape parameters by which mobile organisms orient with respect to the environment. On one hand are principal-axis-based strategies which suggest that organisms extract the major and minor principal axes of space which pass through the centroid and approximate length and width of the entire space, respectively. On the other hand are medial-axis-based strategies which suggest that organisms extract a trunk-and-branch system similar to the skeleton of a shape. With competing explanations comes the necessity to devise experiments capable of producing divergent predictions. Here, we suggest that a recent ...

Stress Alters The Discriminative Stimulus And Response Rate Effects Of Cocaine Differentially In Lewis And Fischer Inbred Rats, Therese A. Kosten, Mindy Miserendino Mar 2012

Stress Alters The Discriminative Stimulus And Response Rate Effects Of Cocaine Differentially In Lewis And Fischer Inbred Rats, Therese A. Kosten, Mindy Miserendino

Psychology Faculty Publications

Stress enhances the behavioral effects of cocaine, perhaps via hypothalamic-pituitary-adrenal (HPA) axis activity. Yet, compared to Fischer 344 (F344) rats, Lewis rats have hyporesponsive HPA axis function and more readily acquire cocaine self-administration. We hypothesized that stress would differentially affect cocaine behaviors in these strains. The effects of three stressors on the discriminative stimulus and response rate effects of cocaine were investigated. Rats of both strains were trained to discriminate cocaine (10 mg/kg) from saline using a two-lever, food-reinforced (FR10) procedure. Immediately prior to cumulative dose (1, 3, 10 mg/kg cocaine) test sessions, rats were restrained for 15-min ...
