Communication And Common Interest, Peter Godfrey-Smith, Manolo Martínez Nov 2013

Communication And Common Interest, Peter Godfrey-Smith, Manolo Martínez

Publications and Research

Explaining the maintenance of communicative behavior in the face of incentives to deceive, conceal information, or exaggerate is an important problem in behavioral biology. When the interests of agents diverge, some form of signal cost is often seen as essential to maintaining honesty. Here, novel computational methods are used to investigate the role of common interest between the sender and receiver of messages in maintaining cost-free informative signaling in a signaling game. Two measures of common interest are defined. These quantify the divergence between sender and receiver in their preference orderings over acts the receiver might perform in each state …

Time-Dependence Of Risperidone And Asenapine Sensitization And Associated D2 Receptor Mechanism, Jun Gao, Ming Li Nov 2013

Time-Dependence Of Risperidone And Asenapine Sensitization And Associated D2 Receptor Mechanism, Jun Gao, Ming Li

Department of Psychology: Faculty Publications

When an antipsychotic drug is given repeatedly and intermittently, there is often a long-term increase in its behavioral efficacy, termed antipsychotic sensitization. With the passage of time, the magnitude of antipsychotic sensitization may increase or decrease depending on the principle of Time-Dependent Sensitization (TDS) or memory decay, respectively. In the present study, we examined the time-dependent feature and possible dopamine D2 receptor mechanism of sensitization induced by the antipsychotics risperidone and asenapine in the conditioned avoidance response test. Well-trained male adult Sprague-Dawley rats were first repeatedly treated with risperidone (1.0 mg/kg) or asenapine (0.2 mg/kg) and tested for avoidance …


Males Show Improved Perspective-Taking Performance When Females Images Occupy Locations In The Spatial Array: Preliminary Evidence Consistent With Sexual Selection Of Spatial Skills?, Bradley R. Sturz, Karen Z. Naufel Nov 2013

Males Show Improved Perspective-Taking Performance When Females Images Occupy Locations In The Spatial Array: Preliminary Evidence Consistent With Sexual Selection Of Spatial Skills?, Bradley R. Sturz, Karen Z. Naufel

Psychology: Faculty Presentations (2009-2022)

One tenet of sexual selection theory posits that females select males on the basis of physical attributes because these attributes serve as indicators of fitness. Relatively recently, evolutionary psychologists have suggested that females also select males on the basis of cognitive attributes because such attributes also serve as indicators of fitness. Spatial abilities are hypothesized to be one such cognitive attribute, but evidence supporting this hypothesis is lacking. We tested this hypothesis by having human male participants engage in a perspective-taking task (imagine standing at object A, facing object B, point to object C). We manipulated the content of the …

For decades, researchers have investigated how events in the prenatal period impact women and their infants. These studies, particularly by researchers in the medical, neuroscience, and behavioral science fields, led to discoveries of important information regarding the prenatal events that were strongly associated with mortality (or death) and morbidity (or incidences of injury, pathology and abnormalities/anomalies, and neurobehavioral sequelae) in the neonatal and infancy periods. Among the many common findings from early research studies, two are particularly noteworthy. First, maternal and fetal risk conditions arising in the prenatal period do not do so in isolation. Sameroff and Chandler characterized this …


Understanding Turnover Propensity Via Affective Beliefs, Adam Bradshaw Oct 2013

Understanding Turnover Propensity Via Affective Beliefs, Adam Bradshaw

Theses and Dissertations

Three latent variable models examined relationships among neuroticism, situation-specific affective beliefs, and turnover propensity and were evaluated with Structural Equation Modeling to determine model fit. Results provided additional insight into how affective belief systems relate to turnover propensity reinforcing and expanding upon previous research by Binning, Bradshaw, LeBreton, and Scheier (2010) as the Correlated Antecedents and the Mediated Antecedents Models fit the data as proposed. Neuroticism and situation-specific affective beliefs continue to play distinguishable roles in explaining turnover propensity. Research by Binning et al. (2010) and the present study make it increasingly clear that understanding how affective belief systems relate …

Counselor Education Faculty Publications and Presentations

Background

Depression is a common and mostly undertreated problem in patients with chronic diseases. However, population-based studies on the association between chronic obstructive pulmonary disease (COPD) and subsequent depression are limited in Asian populations. This study evaluated the incidence and risk factors of depression for patients with COPD in Taiwan.

Methods

Using the claims data from the National Health Insurance of Taiwan, we identified 38,010 COPD patients newly diagnosed in 2000–2004 and 38,010 subjects without COPD frequency, matched by sex, age and index date. The incidence rate and hazard ratio for depression were estimated by the end of 2008.

Residual Fmri Sensitivity For Identity Changes In Acquired Prosopagnosia, Christopher J. Fox, Giuseppe Iaria, Bradley C. Duchaine, Jason J. S. Barton Oct 2013

Residual Fmri Sensitivity For Identity Changes In Acquired Prosopagnosia, Christopher J. Fox, Giuseppe Iaria, Bradley C. Duchaine, Jason J. S. Barton

Dartmouth Scholarship

While a network of cortical regions contribute to face processing, the lesions in acquired prosopagnosia are highly variable, and likely result in different combinations of spared and affected regions of this network. To assess the residual functional sensitivities of spared regions in prosopagnosia, we designed a rapid event-related functional magnetic resonance imaging (fMRI) experiment that included pairs of faces with same or different identities and same or different expressions. By measuring the release from adaptation to these facial changes we determined the residual sensitivity of face-selective regions-of-interest. We tested three patients with acquired prosopagnosia, and all three of these patients …


Social Compass Curriculum: Three Descriptive Case Studies Of Social Skills Outcomes For Students With Autism, Louanne E. Boyd, Deborah M. Ward Oct 2013

Social Compass Curriculum: Three Descriptive Case Studies Of Social Skills Outcomes For Students With Autism, Louanne E. Boyd, Deborah M. Ward

Engineering Faculty Articles and Research

The Social Compass Curriculum (SCC) was investigated for its effectiveness in improving core social skills in three descriptive case studies of students with autism. Treatment fidelity of the SCC was also measured in the school setting. The Social Responsiveness Scale and the Autism Social Skills Profile were completed by parents to measure pre- and postintervention social skills for three students aged 8 to 11 years who participated in the present multisite pilot study. Fidelity of implementation data were collected via a checklist during observations for three educators who implemented the intervention. Results indicate that the SCC improved core social deficits …

The Cognitive Processes Underlying Affective Decision-Making Predicting Adolescent Smoking Behaviors In A Longitudinal Study, C. Anderson Johnson, Lin Xiao, Gilly Koritzky, Antoine Bechara

CGU Faculty Publications and Research

This study investigates the relationship between three different cognitive processes underlying the Iowa Gambling Task (IGT) and adolescent smoking behaviors in a longitudinal study. We conducted a longitudinal study of 181 Chinese adolescents in Chengdu City, China. The participants were followed from 10th to 11th grade. When they were in the 10th grade (Time 1), we tested these adolescents’ decision-making using the IGT and working memory capacity using the Self-ordered Pointing Test (SOPT). Self-report questionnaires were used to assess school academic performance and smoking behaviors. The same questionnaires were completed again at the 1-year follow-up (Time 2). The Expectancy-Valence (EV) …

Randomized Clinical Trial Examining Duration Of Voucher-Based Reinforcement Therapy For Cocaine Abstinence., Kimberly C Kirby, Carolyn M Carpenedo, Karen L Dugosh, Beth J Rosenwasser, Lois A Benishek, Alicia Janik, Rachel Keashen, Elena Bresani, Kenneth Silverman

College of Science & Mathematics Departmental Research

BACKGROUND: This is the first study to systematically manipulate duration of voucher-based reinforcement therapy (VBRT) to see if extending the duration increases abstinence during and following VBRT.

METHODS: We randomized cocaine-dependent methadone-maintained adults to Standard (12 weeks; n=62) or Extended (36 weeks; n=68) VBRT and provided escalating voucher amounts contingent upon urinalysis verification of cocaine abstinence. Urinalysis was scheduled at least every 2 weeks during the 48-week study and more frequently during VBRT (3/week) and 12 weeks of Aftercare (2/week).

RESULTS: Extended VBRT produced longer durations of continuous cocaine abstinence during weeks 1-24 (5.7 vs 2.7 weeks; p=0.003) and proportionally …

Brain and Mind Institute Researchers' Publications

An increasingly popular method of assessing cognitive functions in rodents is the automated touchscreen platform, on which a number of different cognitive tests can be run in a manner very similar to touchscreen methods currently used to test human subjects. This methodology is low stress (using appetitive rather than aversive reinforcement), has high translational potential and lends itself to a high degree of standardization and throughput. Applications include the study of cognition in rodent models of psychiatric and neurodegenerative diseases (e.g., Alzheimer's disease, schizophrenia, Huntington's disease, frontotemporal dementia), as well as the characterization of the role of select brain regions, …

The Touchscreen Operant Platform For Testing Working Memory And Pattern Separation In Rats And Mice., Charlotte A Oomen, Martha Hvoslef-Eide, Christopher J Heath, Adam C Mar, Alexa E Horner, Timothy J Bussey, Lisa M Saksida

Brain and Mind Institute Researchers' Publications

The automated touchscreen operant chamber for rats and mice allows for the assessment of multiple cognitive domains within the same testing environment. This protocol presents the location discrimination (LD) task and the trial-unique delayed nonmatching-to-location (TUNL) task, which both assess memory for location. During these tasks, animals are trained to a predefined criterion during ∼20-40 daily sessions. In LD sessions, touching the same location on the screen is rewarded on consecutive trials, followed by a reversal of location-reward contingencies. TUNL, a working memory task, requires animals to 'nonmatch' to a sample location after a delay. In both the LD and …

Brain and Mind Institute Researchers' Publications

This protocol details a subset of assays developed within the touchscreen platform to measure various aspects of executive function in rodents. Three main procedures are included: extinction, measuring the rate and extent of curtailing a response that was previously, but is no longer, associated with reward; reversal learning, measuring the rate and extent of switching a response toward a visual stimulus that was previously not, but has become, associated with reward (and away from a visual stimulus that was previously, but is no longer, rewarded); and the 5-choice serial reaction time (5-CSRT) task, gauging the ability to selectively detect and …


Diabetes And Prostate Cancer Screening In Black And White Men, Maureen Sanderson, Jay H. Fowke, Loren Lipworth, Xijing Han, Flora Ukoli, Ann L. Coker, William J. Blot, Margaret K. Hargreaves Oct 2013

Diabetes And Prostate Cancer Screening In Black And White Men, Maureen Sanderson, Jay H. Fowke, Loren Lipworth, Xijing Han, Flora Ukoli, Ann L. Coker, William J. Blot, Margaret K. Hargreaves

CRVAW Faculty Journal Articles

PURPOSE: Prior studies conducted primarily among white men find a reduced risk of prostate cancer associated with time since developing diabetes. While biologic explanations are plausible, the association may in part arise from more frequent prostate cancer screening among those with a diabetes diagnosis. The purpose of the present study was to investigate the association between diabetes and prostate cancer screening.

METHODS: We examined differences in prostate cancer screening (prostate-specific antigen and/or digital rectal examination) testing practices after a diabetes diagnosis among lower-income persons living in the southeastern United States and enrolled in the Southern Community Cohort Study between 2002 …


Sexual Coercion And Sexual Violence At First Intercourse Associated With Sexually Transmitted Infections, Corrine M. Williams, Emily R. Clear, Ann L. Coker Oct 2013

Sexual Coercion And Sexual Violence At First Intercourse Associated With Sexually Transmitted Infections, Corrine M. Williams, Emily R. Clear, Ann L. Coker

CRVAW Faculty Journal Articles

BACKGROUND: Violence against women has been associated with subsequent risky sexual behaviors and sexually transmitted infections (STIs). We explored whether sexual coercion or violence at first intercourse was associated with self-reported STIs.

METHODS: Using nationally representative data from the 2006 to 2010 National Survey of Family Growth, we analyzed female respondents aged 18 to 44 (n = 9466) who answered questions on coercion at first intercourse (wantedness, voluntariness, and types of force used) and STIs using logistic regression analyses. We explored degrees of coercion, which we label as neither, sexual coercion (unwanted or nonphysical force), or sexual violence (involuntary or …


Association Of Dietary Intake Patterns With Emotion Regulation, Megan Holt Oct 2013

Association Of Dietary Intake Patterns With Emotion Regulation, Megan Holt

Loma Linda University Electronic Theses, Dissertations & Projects

Background: Western dietary patterns, characterized by high intakes of trans fatty acids (TFA’s), are associated with numerous preventable chronic diseases. Conversely, a Mediterranean dietary pattern is known to be favorably associated with health. Recent findings suggest a correlation between Mediterranean dietary patterns and positive affect, and an inverse correlation with negative affect. Trans fatty acid intake is also associated with negative affect. Further, affect disturbances are associated with emotion dysregulation. We have yet to understand the association of diet with emotion regulation after taking affect disturbances into consideration. The purpose of this study was to examine effects of Mediterranean diet …

Modified Impact Of Emotion On Temporal Discrimination In A Transgenic Rat Model Of Huntington Disease, Alexis Faure, Mouna Es-Sesddiqi, Bruce L. Brown, Hoa P. Nguyen, Olaf Riess, Stephan Von Hörsten, Pascale Le Blanc, Nathalie Desvignes, Bruno Bozon, Nicole El Massioui, Valérie Doyère

Publications and Research

Huntington's disease (HD) is characterized by triad of motor, cognitive, and emotional symptoms along with neuropathology in fronto-striatal circuit and limbic system including amygdala. Emotional alterations, which have a negative impact on patient well-being, represent some of the earliest symptoms of HD and might be related to the onset of the neurodegenerative process. In the transgenic rat model (tgHD rats), evidence suggest emotional alterations at the symptomatic stage along with neuropathology of the central nucleus of amygdala (CE). Studies in humans and animals demonstrate that emotion can modulate time perception. The impact of emotion on time perception has never been …

The cardiac surgical operating room (OR) is a complex environment in which highly trained subspecialists interact with each other using sophisticated equipment to care for patients with severe cardiac disease and significant comorbidities. Thousands of patient lives have been saved or significantly improved with the advent of modern cardiac surgery. Indeed, both mortality and morbidity for coronary artery bypass surgery have decreased during the past decade. Nonetheless, the highly skilled and dedicated personnel in cardiac ORs are human and will make errors. Refined techniques, advanced technologies, and enhanced coordination of care have led to significant improvements in cardiac surgery outcomes.


Effects Of Anger Awareness And Expression Training Versus Relaxation Training On Headaches: A Randomized Trial, Olga Slavin-Spenny, Mark A. Lumley, Elyse R. Thakur, Dana C. Nevedal, Alaa M Hijazi Sep 2013

Effects Of Anger Awareness And Expression Training Versus Relaxation Training On Headaches: A Randomized Trial, Olga Slavin-Spenny, Mark A. Lumley, Elyse R. Thakur, Dana C. Nevedal, Alaa M Hijazi

Psychology Faculty Research Publications

Background and purpose: Stress contributes to headaches, and effective interventions for headaches routinely include relaxation training (RT) to directly reduce negative emotions and arousal. Yet, suppressing negative emotions, particularly anger, appears to augment pain, and experimental studies suggest that expressing anger may reduce pain. Therefore, we developed and tested anger awareness and expression training (AAET) on people with headaches.

Methods: Young adults with headaches (N = 147) were randomized to AAET, RT, or a wait-list control. We assessed affect during sessions, and process and outcome variables at baseline and 4 weeks after treatment.

Results: On process measures, …


Parent Attributional Style And Early Termination From Child And Parent Therapy, Ryan James Mattek Sep 2013

Parent Attributional Style And Early Termination From Child And Parent Therapy, Ryan James Mattek

Dissertations (1934 -)

ABSTRACT

PARENT ATTRIBUTIONAL STYLE AND EARLY TERMINATION

FROM CHILD AND PARENT THERAPY

Ryan J. Mattek, M.A.

Marquette University, 2013

Behavior problems are prevalent in young children and represent a threat to a child's typical development. These early behavior problems are even more common in children from low-income, urban settings. If left untreated, such challenging behaviors may become ingrained and lead to later more severe behaviors including aggression, violence, and anti-social behaviors. Research has demonstrated that participation in child and parent therapy (CPT) programs significantly reduces problematic child behaviors while increasing positive behaviors in both the child and the parent. However, …


Sensory-Specific Appetition: Postingestive Detection Of Glucose Rapidly Promotes Continued Consumption Of A Recently Encountered Flavor, Kevin P. Myers, Marisa S. Taddeo, Emily K. Richards Sep 2013

Sensory-Specific Appetition: Postingestive Detection Of Glucose Rapidly Promotes Continued Consumption Of A Recently Encountered Flavor, Kevin P. Myers, Marisa S. Taddeo, Emily K. Richards

Faculty Journal Articles

It is generally thought that macronutrients stimulate intake when sensed in the mouth (e.g., sweet taste) but as food enters the GI tract its effects become inhibitory, triggering satiation processes leading to meal termination. Here we report experiments extending recent work (see [1]) showing that under some circumstances nutrients sensed in the gut produce a positive feedback effect, immediately promoting continued intake. In one experiment, rats with intragastric (IG) catheters were accustomed to consuming novel flavors in saccharin daily while receiving water infused IG (5 ml/15 min). The very first time glucose (16% w/w) was infused IG instead of water, …


Supervisees' Experiences Of Ruptures In Multicultural Supervision: A Qualitative Study, Laura Lubbers Sep 2013

Supervisees' Experiences Of Ruptures In Multicultural Supervision: A Qualitative Study, Laura Lubbers

Dissertations (1934 -)

As the paradigmatic shift of multiculturalism emerges in counseling, the constructs of culture and context warrant examination in the supervision process. With an understanding that conflict is inevitable in supervision relationships particularly when cultural topics are being discussed, investigation into the process of ruptures and rupture repair as they take place within multicultural supervision is warranted. Despite the attention paid to addressing culture in supervision, surprisingly little empirical attention has focused on supervisee experiences of ruptures in multicultural supervision. This study sought to provide a deeper understanding of supervisees' experiences of ruptures in multicultural supervision. Twelve participants were interviewed regarding …

Predicting Health Trajectories, Singapore Management University

Perspectives@SMU

With data going back to pre-World War II, the HRS paints a picture of how we will age . As people age, men are less likely to have physical disabilities than women, but die earlier. Those with higher socio-economic status and education levels have less physical disabilities as they grow old. Less educated single women are often the least financially prepared for retirement.

Those are the main findings of the U.S. Health and Retirement Study (HRS), described as "the mother ship" of statistics on aging by Michael Hurd, Principal Senior Researcher and Director at the RAND Center for the …


A Multivariate Method To Determine The Dimensionality Of Neural Representation From Population Activity., Jörn Diedrichsen, Tobias Wiestler, Naveed Ejaz Aug 2013

A Multivariate Method To Determine The Dimensionality Of Neural Representation From Population Activity., Jörn Diedrichsen, Tobias Wiestler, Naveed Ejaz

Brain and Mind Institute Researchers' Publications

How do populations of neurons represent a variable of interest? The notion of feature spaces is a useful concept to approach this question: According to this model, the activation patterns across a neuronal population are composed of different pattern components. The strength of each of these components varies with one latent feature, which together are the dimensions along which the population represents the variable. Here we propose a new method to determine the number of feature dimensions that best describes the activation patterns. The method is based on Gaussian linear classifiers that use only the first d most important pattern …


Parenting And Attachment Among Low-Income African-American And Caucasian Preschoolers, Casey A. Dexter, Kristyn Wong, Ann M. Stacks, Marjorie Beeghly, Douglas Barnett Aug 2013

Parenting And Attachment Among Low-Income African-American And Caucasian Preschoolers, Casey A. Dexter, Kristyn Wong, Ann M. Stacks, Marjorie Beeghly, Douglas Barnett

Psychology Faculty Research Publications

Despite a plethora of research on parenting and infant attachment, much less is known about the contributions of parenting to preschool attachment, particularly within different racial groups. This study seeks to build on the extant literature by evaluating whether similar associations between parenting and attachment can be observed in African American and Caucasian families, and whether race moderates them. Seventy-four primary caregivers and their preschool children (51% African American, 49% Caucasian, 46% male) from similar urban, low income backgrounds participated in two visits four weeks apart when children were between four and five years of age. Attachment was scored from …


Unpacking The Temperament Weight Relationship: The Mediating Role Of Food Preferences, Sarah A. Berry Aug 2013

Unpacking The Temperament Weight Relationship: The Mediating Role Of Food Preferences, Sarah A. Berry

Electronic Theses and Dissertations

The current study examined the mediating role of possible food preferences on the temperamentweight relationship among 18-month-old toddlers. Parents of 37 typically developing toddlers completed the Early Childhood Behavior Questionnaire (ECBQ). During a lab visit toddlers’ weight and recumbent length were measured and recorded. Toddlers also completed a sequential touching task to examine their ability to categorize a healthy group of foods and an unhealthy group of foods. The only temperament measure found to associate with both child weight status and food categorization was inhibitory control. Toddlers’ food categorization was not found to mediate the relationship between inhibitory control and …


An Empirical Examination Of The Associations Among Crystal Methamphetamine Use History, Posttraumatic Stress Symptom Severity, And Perceived Social Support, Courtney Elaine Dutton Aug 2013

An Empirical Examination Of The Associations Among Crystal Methamphetamine Use History, Posttraumatic Stress Symptom Severity, And Perceived Social Support, Courtney Elaine Dutton

Graduate Theses and Dissertations

Social support functions as a protective factor against the development of posttraumatic stress disorder (PTSD). Crystal methamphetamine use, however, is associated with a decrease in Social functioning. This is noteworthy as people with PTSD endorse elevated rates of crystal methamphetamine use. The current study proposed to look at perceived Social support as it relates to crystal methamphetamine use among individuals endorsing a wide range of posttraumatic stress symptoms. Questionnaires measuring perceived Social support and posttraumatic stress symptom severity were administered to 98 traumatic event-exposed adults (Mage = 48.5, SD =7.74) recruited from the San Francisco bay area who …


Examination Of The Pediatric Diabetes Routines Questionnaire In Adolescents: Development Of An Adolescent Self-Report Version And Confirmatory Factor Analysis, Jessica Sima Pierce Aug 2013

Examination Of The Pediatric Diabetes Routines Questionnaire In Adolescents: Development Of An Adolescent Self-Report Version And Confirmatory Factor Analysis, Jessica Sima Pierce

Dissertations

Previous literature suggests a positive relationship between general child routines and diabetes treatment adherence. However, research examining routines specific to the diabetes regimen is lacking. Recently, the Pediatric Diabetes Routines Questionnaire (PDRQ) was developed as a parent-report measure of diabetes-specific routines for children and adolescents with type 1 diabetes. Though the PDRQ has provided a means to measure routines specific to the diabetes regimen, limitations exist in regard to its use with adolescents. Thus, the goals of this study were to develop and evaluate a parallel adolescent self-report version (PDRQ: Adolescent; PDRQ:A) of the PDRQ and to examine the psychometric …
