Contributions Of Dynamic Systems Theory To Cognitive Development, John P. Spencer, Andrew Austin, Anne R. Schutte

Department of Psychology: Faculty Publications

This paper examines the contributions of dynamic systems theory to the field of cognitive development, focusing on modeling using dynamic neural fields. A brief overview highlights the contributions of dynamic systems theory and the central concepts of dynamic field theory (DFT). We then probe empirical predictions and findings generated by DFT around two examples—the DFT of infant perseverative reaching that explains the Piagetian A-not-B error, and the DFT of spatial memory that explain changes in spatial cognition in early development. A systematic review of the literature around these examples reveals that computational modeling is having an impact on empirical research …

Association Between The Serotonin Transporter Triallelic Genotype And Eating Problems Is Moderated By The Experience Of Childhood Trauma In Women, Scott F. Stoltenberg, Cynthia Anderson, Parthasarathi Nag, Cheryl Anagnopoulos

Department of Psychology: Faculty Publications

Objective—This study investigated a potential interaction between the triallelic polymorphism of the serotonin transporter gene (SLC6A4) promoter and the experience of childhood trauma on the number of problem eating behaviors.

Methods—The study sample was comprised of 439 (64.7% female) Caucasian college students (mean age = 22.49, SD = 6.12). Participants completed questionnaires that assessed eating problems and experience of trauma in childhood (ages 0-12) and donated cheek cells for 5- HTTLPR and rs25531 genotyping.

Results—Women carrying a lower expressing allele (i.e. LG or S) who were exposed to higher levels of childhood trauma reported significantly higher mean numbers of eating …

Neural Mechanisms Underlying Neurooptometric Rehabilitation Following Traumatic Brain Injury, Caitlin M. Hudac, Srinivas Kota, James L. Nedrow, Dennis L. Molfese

Department of Psychology: Faculty Publications

Mild to severe traumatic brain injuries have lasting effects on everyday functioning. Issues relating to sensory problems are often overlooked or not addressed until well after the onset of the injury. In particular, vision problems related to ambient vision and the magnocellular pathway often result in posttrauma vision syndrome or visual midline shift syndrome. Symptoms from these syndromes are not restricted to the visual domain. Patients commonly experience proprioceptive, kinesthetic, vestibular, cognitive, and language problems. Neurooptometric rehabilitation often entails the use of corrective lenses, prisms, and binasal occlusion to accommodate the unstable magnocellular system. However, little is known regarding the …

Mixed-Methods Research Methodologies, Steven R. Terrell

The Qualitative Report

Mixed-Method studies have emerged from the paradigm wars between qualitative and quantitative research approaches to become a widely used mode of inquiry. Depending on choices made across four dimensions, mixed-methods can provide an investigator with many design choices which involve a range of sequential and concurrent strategies. Defining features of these designs are reported along with quality control methods, and ethical concerns. Useful resources and exemplary study references are shared.

Synthesizing Parasitology With Archaeology In Paleopathology, Karl Reinhard, Adauto Araujo

Karl Reinhard Publications

Parasitology is the study of organisms that are symbiotic with other organisms. In this form of symbiosis, the parasite species by definition benefits from the interaction while the host is harmed to some degree. In actuality, some parasites benefit their hosts. The animals traditionally studied by parasitologists range from protozoa to arthropods, and include all types of internal and external worms. Ticks, fleas, lice, and a variety of insects that transmit parasites are also studied by parasitologists. Recently, a more holistic view of parasitism appeared, including bacteria and viruses. In essence, parasitology is the study of a certain kind of …

Clinical Phd Graduate Student Views Of Their Scientist-Practitioner Training, Joseph W. Vanderveen, L Felice Reddy, Jennifer C. Veilleux, Alicia M. January, David Dilillo

Department of Psychology: Faculty Publications

Objectives: The goal of the scientist-practitioner (S-P) training model is to produce clinical psycholo-gists equipped to integrate and utilize both science and practice in the clinical and research domains. However, much has been written regarding the possible shortcomings of S-P training and whether clinical psychology graduate students are actually gaining the knowledge and skills to integrate sci-ence and practice during graduate training and beyond (Chang, Lee, & Hargreaves, 2008; Gelso, 2006; Merlo, Collins, & Bernstein, 2008; Phillips, 1993). Methods: As such, the present study assessed ratings of satisfaction, perception of ability, and use of the S-P training model within 653 …

Iptakalim Preferentially Decreases Nicotine-Induced Hyperlocomotion In Phencyclidine-Sensitized Rats: A Potential Dual Action Against Nicotine Addiction And Psychosis, Nick Volf, Gang Hu, Ming Li

Department of Psychology: Faculty Publications

Objective: Iptakalim is a putative ATP-sensitive potassium (KATP) channel opener. It is also a novel nicotinic acetylcholine receptor (nAChR) blocker and can antagonize nicotine-induced increase in dopamine release in the nucleus accumbens. Our recent work also shows that iptakalim exhibits a clozapine-like atypical antipsychotic profile, indicating that iptakalim may possess a dual action against nicotine addiction and schizophrenia.

Methods: The present study examined the potential therapeutic effects of iptakalim on nicotine use in schizophrenia. We created an animal model of comorbidity of nicotine addiction and schizophrenia by injecting male Sprague-Dawley rats with nicotine (0.40 mg/kg, subcutaneously［sc］) or saline, in combination …

Conditioned Response Evoked By Nicotine Conditioned Stimulus Preferentially Induces C-Fos Expression In Medial Regions Of Caudate-Putamen, Sergios Charntikov, Matthew E. Tracy, Changjiu Zhao, Ming Li, Rick A. Bevins

Department of Psychology: Faculty Publications

Nicotine has both unconditioned and conditioned stimulus properties. Conditioned stimulus properties of nicotine may contribute to the tenacity of nicotine addiction. The purpose of this experiment was to use neurohistochemical analysis of rapidly developing c-Fos protein to elucidate neurobiological loci involved in the processing of nicotine as an interoceptive conditioned stimulus (CS). Rats were injected (SC) in an intermixed fashion with saline or nicotine (16 sessions of each) and placed in conditioning chambers where they were given one of the three conditions depending on group assignment: (a) nicotine paired 100% of the time with intermittent access to sucrose (nicotine-CS condition), …

Differential Effects Of Acute Amphetamine And Phencyclidine Treatment And Withdrawal From Repeated Amphetamine Or Phencyclidine Treatment On Social Interaction And Social Memory In Rats, Ming Li, Wei He, Rebecca Munro

Department of Psychology: Faculty Publications

Although animal models based on amphetamine (AMPH) or phencyclidine (PCP) treatment have been used extensively to study the neurobiological and behavioral characteristics of schizophrenia, there are conflicting reports regarding their validity in modeling the negative symptoms and cognitive deficits of schizophrenia. The present study examined how acute AMPH or PCP treatment (Experiment 1) and withdrawal from repeated AMPH treatment (Experiment 2) or PCP treatment (Experiment 3) affects social behavior and social recognition memory in male Sprague-Dawley rats. Each subject was tested on two consecutive days. On the first day, the rats were tested four times (5 min/each) at 10-min intervals …

Gender Differences In Head Impacts Sustained By Collegiate Ice Hockey Players, Lindley L. Brainard, Jonathan G. Beckwith, Jeffrey J. Chu, Joseph J. Crisco, Thomas W. Mcallister, Ann-Christine Duhaime,, Arthur C. Maerlender, Richard M. Greenwald

Department of Psychology: Faculty Publications

Purpose—This study aims to quantify the frequency, magnitude, and location of head impacts sustained by male and female collegiate ice hockey players over two seasons of play.

Methods—Over two seasons, 88 collegiate athletes (51 female, 37 male) on two female and male NCAA varsity ice hockey teams wore instrumented helmets. Each helmet was equipped with 6 single-axis accelerometers and a miniature data acquisition system to capture and record head impacts sustained during play. Data collected from the helmets were post-processed to compute linear and rotational acceleration of the head as well as impact location. The head impact exposure data (frequency, …

A Review Of Return To Play Issues And Sports-Related Concussion, Amy W. Doolan, Daniel D. Day, Arthur C. Maerlender, Michael Goforth, P. Gunnar Brolinson

Department of Psychology: Faculty Publications

Mild traumatic brain injury in sports has become a significant public health concern which has not only received the general public’s attention through multiple news media stories involving athletic concussions but has also resulted in local, state, and national legislative efforts to improve recogni-tion and management. The purpose of this article is to review the current literature for return to play (RTP) guidelines. State, regional, national, and professional legislation on sport-related concussion RTP management issues will be reviewed. This article will be helpful in developing a generalized systematic approach to concussion management and highlight specific RTP guidelines. The article will …

Rotational Head Kinematics In Football Impacts: An Injury Risk Function For Concussion, Steven Rowson, Stefan M. Duma, Jonathan G. Beckwith, Jeffrey J. Chu, Richard M. Greenwald, Joseph J. Crsico, P. Gunnar Brolinson, Ann-Christine Duhaime, Thomas W. Mcallister, Arthur C. Maerlender

Department of Psychology: Faculty Publications

Recent research has suggested a possible link between sports-related concussions and neurodegen-erative processes, highlighting the importance of developing methods to accurately quantify head impact tolerance. The use of kinematic parameters of the head to predict brain injury has been sug-gested because they are indicative of the inertial response of the brain. The objective of this study is to characterize the rotational kinematics of the head associated with concussive impacts using a large head acceleration dataset collected from human subjects. The helmets of 335 football players were instrumented with accelerometer arrays that measured head acceleration following head impacts sustained during play, …

Disentangling The Nature Of The Nicotine Stimulus, Rick A. Bevins, Scott T. Barrett, Robert J. Polewan, Steven T. Pittenger, Natashia Swalve, Sergios Charntikov

Department of Psychology: Faculty Publications

Learning involving interoceptive stimuli likely plays an important role in many diseases and psychopathologies. Within this area, there has been extensive research investigating the interoceptive stimulus effects of abused drugs. In this pursuit, behavioral pharmacologists have taken advantage of what is known about learning processes and adapted the techniques to investigate the behavioral and receptor mechanisms of drug stimuli. Of particular interest is the nicotine stimulus and the use of the two-lever operant drug discrimination task and the Pavlovian drug discriminated goal-tracking task. There is strong concordance between the two methods when using “standard” testing protocols that minimize learning on …

Exploring The Relationships Of Perceived Discrimination, Anger, And Aggression Among North American Indigenous Adolescents, Kelley J. Sittner Hartshorn, Les B. Whitbeck, Dan R. Hoyt

Department of Sociology: Faculty Publications

A growing body of research has documented associations between discrimination, anger, and delinquency, but the exact nature of these associations remains unclear. Specifically, do aggressive behaviors emerge over time as a consequence of perceived discrimination and anger? Or do adolescents who engage in aggressive behavior perceive that they are being discriminated against and become angry? We use autoregressive cross-lagged path analysis on a sample of 692 Indigenous adolescents (mean age = 12 years) from the Northern Midwest and Canada to answer these research questions. Results showed that the direction of effects went only one way; both perceived discrimination and anger …

A Cluster Analysis Of Service Utilization And Incarceration Among Homeless Youth, Lisa A. Kort-Butler, Kimberly A. Tyler

Department of Sociology: Faculty Publications

Our paper examines service usage (e.g., shelter) as well as a typology of individuals who are most likely to use groupings of services among 249 homeless youth. Our results revealed that the majority of homeless young people have used food programs (66%) and street outreach (65%) on at least one occasion within the past year. Cluster analysis of services revealed four distinct groups: (1) basic survival service use, characterized by above average shelter, food, and outreach service use, but below average on counseling, substance abuse/ mental health services, and incarceration; (2) multiple service use, which included above average use of …

Poor Parenting And Antisocial Behavior Among Homeless Young Adults : Links To Dating Violence Perpetration And Victimization, Kimberly A. Tyler, Lisa Melander

Department of Sociology: Faculty Publications

Though research has examined risk factors associated with street victimization among homeless young people, little is known about dating violence experiences among this group. Given homeless youths’ elevated rates of child maltreatment, it is likely that they are at high risk for dating violence. As such, the current study examined the association between child maltreatment and parental warmth with dating violence perpetration and victimization through substance use and delinquency among a sample of 172 homeless males and females. Results from path analysis revealed that physical abuse, sexual abuse, and neglect were all significant correlates of both substance use and delinquency, …

Correlates Of Service Utilization Among Homeless Youth, Kimberly A. Tyler, Sarah Akinyemi, Lisa Kort-Butler

Department of Sociology: Faculty Publications

Though few studies exist on service utilization among homeless youth in the U.S., services are important because without them, many of these young people may resort to delinquent strategies in order to meet their daily survival needs. The current study examines frequency and correlates of service utilization (i.e., shelters, food programs, street outreach, counseling, STI and HIV testing) among a sample of 249 homeless youth ages 14 to 21. Multivariate analysis revealed significant differences in service usage by sex, age, and sexual orientation. Experiencing family physical and/or sexual abuse, being kicked out of the family home, spending more nights per …

An Examination Of Within-Person Variation In Response Propensity Over The Data Collection Field Period, Kristen Olson, Robert M. Groves

Department of Sociology: Faculty Publications

Statistical examinations of deterministic and stochastic response propensity assert that a sample case’s propensity is determined by fixed respondent characteristics. The perspective of this article, that of dynamic response propensities, differs, viewing sample cases’ propensities as evolving over the course of the data collection. Each sample case begins the data collection period in a “base” response propensity. Each change in the data collection protocol which the survey organization subsequently makes might change that base propensity. This article examines four questions: (1) Is there any evidence that the average response propensities of sampled individuals vary over the data collection? (2) Is …

Does Giving People Their Preferred Survey Mode Actually Increase Survey Participation Rates? An Experimental Examination, Kristen Olson, Jolene D. Smyth, Heather M. Wood

Department of Sociology: Faculty Publications

Survey research has long grappled with the concept of survey mode preference: the idea that a respondent may prefer to participate in one survey mode over another. This article experimentally examines the effect of mode preference on response, contact, and cooperation rates; mode choice; and data collection efficiency. Respondents to a 2008 telephone survey (n = 1,811; AAPOR RR3 = 38 percent) were asked their mode preference for future survey participation. These respondents were subsequently followed up in 2009 with two independent survey requests. The first follow-up survey request was another telephone survey (n = 548; AAPOR RR2 = 55.5 …

Adolescent Violent Victimization And Precocious Union Formation, Danielle C. Kuhl, David F. Warner, Andrew Wilczak

Department of Sociology: Faculty Publications

This article bridges scholarship in criminology and family sociology by extending arguments about “precocious exits” from adolescence to consider early union formation as a salient outcome of violent victimization for youths. Research indicates that early union formation is associated with several negative outcomes; yet the absence of attention to union formation as a consequence of violent victimization is noteworthy. We address this gap by drawing on life course theory and data from the National Longitudinal Study of Adolescent Health (Add Health) to examine the effect of violent victimization (“street” violence) on the timing of first coresidential union formation—differentiating between marriage …

Macrostructure From Microstructure: Generating Whole Systems From Ego Networks, Jeffrey A. Smith

Department of Sociology: Faculty Publications

This paper presents a new simulation method to make global network inference from sampled data. The proposed simulation method takes sampled ego network data and uses Exponential Random Graph Models (ERGM) to reconstruct the features of the true, unknown network. After describing the method, the paper presents two validity checks of the approach: the first uses the 20 largest Add Health networks while the second uses the Sociology Coauthorship network in the 1990’s. For each test, I take random ego network samples from the known networks and use my method to make global network inference. I find that my method …

Discussion On The Paper By Neumann, Evett And Skerrett, Michael J. Saks, Ashley M. Votruba

Department of Psychology: Faculty Publications

Neumann, Evett, and Skerrett have made a major contribution to the art and science of fingerprint identification. This is an important—perhaps historic—step forward in the intellectual history of fingerprint identification and perhaps other fields of pattern matching forensic science. Their work deals ingeniously with the elusive problem of placing forensic identification on an empirically sound, quantitative foundation.

Correlates Of Homeless Episodes Among Indigenous People, Les B. Whitbeck, Devan M. Crawford, Kelley J. Sittner Hartshorn

Department of Sociology: Faculty Publications

This study reports the correlates of homeless episodes among 873 Indigenous adults who are part of an ongoing longitudinal study on four reservations in the Northern Midwest and four Canadian First Nation reserves. Descriptive analyses depict differences between those who have and have not experienced an episode of homelessness in their lifetimes. Multivariate analyses assess factors associated with a history of homeless episodes at the time of their first interview. Results show that individuals with a history of homeless episodes had significantly more individual and family health, mental health, and substance abuse problems. Periods of homelessness also were associated with …

Factors Associated With Growth In Daily Smoking Among Indigenous Adolescents, Les B. Whitbeck, Kelley J. Sittner Hartshorn, Julia Mcquillan, Devan M. Crawford

Department of Sociology: Faculty Publications

North American Indigenous adolescents smoke earlier, smoke more, and are more likely to become regular smokers as adults than youth from any other ethnic group yet we know very little about their early smoking trajectories. We use multilevel growth modeling across five waves of data from Indigenous adolescents (aged 10 to 13 years at Wave 1) to investigate factors associated with becoming a daily smoker. Several factors, including number of peers who smoked at Wave 1 and meeting diagnostic criteria for major depressive episode and conduct disorder were associated with early daily smoking. Only age and increases in the number …

Implicit And Explicit Alcohol-Related Motivations Among College Binge Drinkers, Laura C. Herschl, Dennis E. Mcchargue, James Mackillop, Scott F. Stoltenberg, Krista B. Highland

Department of Psychology: Faculty Publications

Rationale: Positive alcohol outcome expectancies and behavioral economic indices of alcohol consumption are related to binge drinking among college students and may reflect explicit and implicit motivations that are differentially associated with this behavior. Objectives: The present study hypothesized that implicit (alcohol purchase task) and explicit (positive expectancy for alcohol’s effects) motivations for drinking would not be correlated. It was also hypothesized that greater implicit and explicit motivations would predict alcohol-related risk. Methods: Participants were 297 college student binge drinkers (54% female; 88% European-American; Alcohol Use Disorders Identification Test: M = 9.53, SD = 5.04). Three indices from the …

Manufacturing Change, Una Ruddock

The Qualitative Report

This is a highly accessible presentation of organisational research, which demonstrates how ethnography can elicit a holistic understanding of across section of employees and thereby reveal a workplace culture. It suggests that change efforts fail if culture is ignored and offers a detailed account of how critical incidents translate into tools for change. The data analysis reveals the weakness in working relationships and how blame functions to prevent change. The Ideal Plant project emerges, which validates transformation tools to create cooperative workplace interactions and collaborative problem solving. The past and future, metaphorically represented as two different places, are connected by …

The ‘Friendship Dynamics Of Religion,’ Or The ‘Religious Dynamics Of Friendship’? A Social Network Analysis Of Adolescents Who Attend Small Schools, Jacob Cheadle, Philip Schwadel

Department of Sociology: Faculty Publications

Longitudinal social network data on adolescents in seven schools are analyzed to reach a new understanding about how the personal and interpersonal social dimensions of adolescent religion intertwine together in small school settings. We primarily address two issues relevant to the sociology of religion and sociology in general: (1) social selection as a source of religious homophily and (2) friend socialization of religion. Analysis results are consistent with Collins’ interaction ritual chain theory, which stresses the social dimensions of religion, since network–religion autocorrelations are relatively substantial in magnitude and both selection and socialization mechanisms play key roles in generating them. …

Book Review: Making Chastity Sexy: The Rhetoric Of Evangelical Abstinence Campaigns, By Christine J. Gardner, Kelsy Burke

Department of Sociology: Faculty Publications

Evangelical messages about adolescent sexuality appear straight-forward: unless they are married (and heterosexual), teens should not have sex. However, as communications scholar Christine J. Gardner shows in her book, Making Chastity Sexy: The Rhetoric of Evangelical Abstinence Campaigns, how evangelicals go about promoting abstinence is both complicated and unexpected. Gardner focuses on how social meanings about religion and sexuality are constructed in evangelical abstinence campaign by examining the rhetoric of three U.S. campaigns (the primary focus of the book) and one African campaign. One of her most surprising findings—and the one for which the book’s title is based—is that U.S. …
