Father–Daughter Bonds: A Comparison Of Adolescent Daughters’ Relationships With Resident Biological Fathers And Stepfathers, Cynthia G. Campbell, Elizabeth J. Winn

Psychological Sciences Faculty Publications and Presentations

Objective: To investigate whether the interpersonal dynamics of closeness are different in stepfather–stepdaughter versus father–daughter relationships during adolescence.

Background: Establishing a general process model of the relational factors contributing to greater closeness between fathers and daughters is a preliminary step toward examining variations in such processes.

Method: The data were from the National Longitudinal Study of Adolescent to Adult Health (ADD Health), a nationally representative sample of adolescents. Respondents were female adolescents who were living with either a biological father (n = 1,881) or stepfather (n = 273) and reported on the availability and involvement of their (step)fathers, …

Promoting Critical Thinking Through Service Learning: A Home-Visiting Case Study, Cynthia G. Campbell, Brianna R. Oswald

Psychological Sciences Faculty Publications and Presentations

As stated in APA Learning Outcomes 2 and 3, two central goals of higher education instruction are promoting students’ critical thinking skills and connecting student learning to real-life applications. To meet these goals, a community-based service-learning experience was designed using task value, interpersonal accountability, cognitive dissonance, and guided reflection, and was implemented to motivate and promote students’ critical thinking skills in a human development psychology course. Students in this course served as home visitors or support-group facilitators to vulnerable families and reflected on their experiences in class assignments. Qualitative evidence from class discussions and journal entries, and quantitative data from …

Circadian Rhythms Of Body Temperature And Locomotor Activity In The Antelope Ground Squirrel, Ammospermophilus Leucurus, Roberto Refinetti, G. J. Kenagy

Psychological Sciences Faculty Publications and Presentations

We studied circadian rhythms of body temperature and locomotor activity in antelope ground squirrels (Ammospermophilus leucurus) under laboratory conditions of a 12L:12D light-dark cycle and in constant darkness. Antelope ground squirrels are diurnally active and, exceptionally among ground squirrels and other closely related members of the squirrel family in general, they do not hibernate. Daily oscillations in body temperature consisted of a rise in temperature during the daytime activity phase of the circadian cycle and a decrease in temperature during the nighttime rest phase. The body temperature rhythms were robust (71% of maximal strength) with a daily range …

Civility And Academic Freedom: Who Defines The Former (And How) May Imperil Rights To The Latter, Theodore W. Mcdonald, James D. Stockton, R. Eric Landrum

Psychological Sciences Faculty Publications and Presentations

An alarming occurrence in academia involves the discipline of faculty, under the guise of violating civility or collegiality codes, for engaging in what should be protected academic free speech. This often occurs when unprincipled and/or corporate-minded administrators seek to punish or dissuade faculty from challenging or questioning their decisions or policy initiatives, or for speaking up about policy violations or lack of due process. The ambiguity of terms such as civility and collegiality, when selectively defined by administrators, can be used to stifle, dissuade or punish academic free speech. Ways to identify and address these problems are presented.

Daily Rhythmicity Of Behavior Of Nine Species Of South American Feral Felids In Captivity, Sciabarrasi Bagilet Antonio, Raúl Delmar Cerutti, María Cristina Scaglione, Giuseppe Piccione, Roberto Refinetti

Psychological Sciences Faculty Publications and Presentations

The authors analyzed the daily activity rhythms of the domestic cat and of eight of the ten feral felid species that are indigenous to South America. All species showed daily rhythmicity of activity in captivity under a natural light-dark cycle. The robustness of the rhythmicity varied from species to species, but the grand mean of 34% was within the range of robustness previously described for mammalian species ranging in size from mice to cattle. There was not a sharp division between diurnal and nocturnal felids. Instead, what was found was a gradient of diurnality going from the predominantly nocturnal margay …

Parenting And Adolescents’ Psychological Adjustment: Longitudinal Moderation By Adolescents’ Genetic Sensitivity, April S. Masarik

Psychological Sciences Faculty Publications and Presentations

We examined whether adolescents’ genetic sensitivity, measured by a polygenic index score, moderated the longitudinal associations between parenting and adolescents’ psychological adjustment. The sample included 323 mothers, fathers, and adolescents (177 female, 146 male; Time 1 [T1] average age = 12.61 years, SD = 0.54 years; Time 2 [T2] average age = 13.59 years, SD = 0.59 years). Parents’ warmth and hostility were rated by trained, independent observers using videotapes of family discussions. Adolescents reported their symptoms of anxiety, depressed mood, and hostility at T1 and T2. The results from autoregressive linear regression models showed that adolescents’ genetic sensitivity moderated …

Chronotype, Class Times, And Academic Achievement Of University Students, Tristan Enright, Roberto Refinetti

Psychological Sciences Faculty Publications and Presentations

Numerous studies over the years have documented an effect of human chronotypes on physiological and psychological processes. Studies evaluating the impact of an individual’s chronotype on his/her academic achievement have indicated that morning chronotypes have an academic advantage over evening chronotypes. However, these studies did not account for the time of day in which the participants were being evaluated. The goal of the present study was to examine whether morning chronotypes do have an academic advantage over evening chronotypes when the time-of-day of classes and exams is taken into consideration. We obtained morningness-eveningness scores and course grades from 207 university …

Western Diet Affects The Murine Circadian System Possibly Through The Gastrointestinal Microbiota, Roberto Refinetti

Psychological Sciences Faculty Publications and Presentations

Consumption of a high-fat diet characteristic of human Western diet has been shown to affect the circadian system of laboratory rodents. The present study confirms an effect of Western diet on the circadian system of mice, specifically a shortening of the free-running circadian period of running-wheel activity, in addition to increased weight gain. Decimation of the gut microbiota by broad spectrum antibiotic treatment reversed the effect of Western-diet feeding on the free-running period, which suggests that the effect of Western-diet feeding on the circadian system is mediated by the gastrointestinal microbiota. This finding is particularly relevant in view of recent …

Stress And Child Development: A Review Of The Family Stress Model, April S. Masarik, Rand D. Conger

Psychological Sciences Faculty Publications and Presentations

In the present report, we provide an illustrative review of the Family Stress Model (FSM) framework¹ to understand how family stress influences children across development in physical, social-emotional, and cognitive domains. We note that the FSM as a theory has evolved through inspection of: (a) new explanatory pathways (mediators); (b) factors that moderate FSM pathways; and (c) joint tests of competing models. Also important, most researchers cited in this review used longitudinal designs to test the proposed causal ordering of FSM pathways, which replicated among a diverse set of families varied in structure, ethnic background, and geographic location. We …

Daily Rhythms Of Physiological Parameters In The Dromedary Camel Under Natural And Laboratory Conditions, Ahmed A. Al-Haidary, Khalid A. Abdoun, Emad M. Samara, Aly B. Okab, Mamane Sani, Roberto Refinetti

Psychological Sciences Faculty Publications and Presentations

Camels are well adapted to hot arid environments and can contribute significantly to the economy of developing countries in arid regions of the world. Full understanding of the physiology of camels requires understanding of the internal temporal order of the body, as reflected in daily or circadian rhythms. In the current study, we investigated the daily rhythmicity of 20 physiological variables in camels exposed to natural oscillations of ambient temperature in a desert environment and compared the daily temporal courses of the variables. We also studied the rhythm of core body temperature under experimental conditions with constant ambient temperature in …

Variability Of Behavioral Chronotypes Of 16 Mammalian Species Under Controlled Conditions, Roberto Refinetti

Psychological Sciences Faculty Publications and Presentations

Human chronotypes (differences in preference for early or late rising each day) have been extensively studied in recent years, but no attempt has been made to compare human chronotypes with the chronotypes of other animal species. We evaluated behavioral chronotypes in 16 mammalian species along a body size gradient of five orders of magnitude (from mice to cattle). Individuals of all species were studied under a 12L:12D photoperiod in a thermoneutral environment with food and water available at all times. Rhythms of locomotor activity were analyzed for onset time, acrophase, and robustness. Neither of these rhythmic parameters was significantly related …

Couple Resilience To Economic Pressure Over Time And Across Generations, April S. Masarik, Monica J. Martin, Emilio Ferrer, Frederick O. Lorenz, Katherine J. Conger, Rand D. Conger

Psychological Sciences Faculty Publications and Presentations

Research suggests that economic stress disrupts perceived romantic relationship quality; yet less is known regarding the direct influence of economic stress on negative behavioral exchanges between partners over time. Another intriguing question concerns the degree to which effective problem-solving might protect against this hypothesized association. To address these issues, the authors studied two generations of couples who were assessed approximately 13 years apart (Generation 1: N = 367, Generation 2: N = 311). On average and for both generations, economic pressure predicted relative increases in couples’ hostile, contemptuous, and angry behaviors; however, couples who were highly effective problem solvers experienced …

Daily Activity And Nest Occupation Patterns Of Fox Squirrels (Sciurus Niger) Throughout The Year, Thomas Wassmer, Roberto Refinetti

Psychological Sciences Faculty Publications and Presentations

The authors investigated the general activity and nest occupation patterns of fox squirrels in a natural setting using temperature-sensitive data loggers that measure activity as changes in the microenvironment of the animal. Data were obtained from 25 distinct preparations, upon 14 unique squirrels, totaling 1385 recording days. The animals were clearly diurnal, with a predominantly unimodal activity pattern, although individual squirrels occasionally exhibited bimodal patterns, particularly in the spring and summer. Even during the short days of winter (9 hours of light), the squirrels typically left the nest after dawn and returned before dusk, spending only about 7 hours out …

The Individual Day-To-Day Process Of Social Anxiety In Vulnerable College Students, Cynthia G. Campbell, Karen L. Bierman, Peter C. M. Molenaar

Psychological Sciences Faculty Publications and Presentations

Transitions requiring the creation of new social networks may be challenging for individuals vulnerable to social anxiety, which may hinder successful adjustment. Using person-specific methodology, this study examined social anxiety in vulnerable university freshman away from home during their first semester of college to understand how day-to-day processes of social anxiety influenced future social anxiety and social withdrawal. Participants completed daily measures of four components of social anxiety which were examined as a process during a single day, and as a process affecting social anxiety and social withdrawal the next day. For most individuals, same day fear of negative evaluation …

Anger And Hostility As Primary Externalizing Features Of Depression In College Men, Matthew Genuchi

Psychological Sciences Faculty Publications and Presentations

Some have suggested that Major Depressive Disorder diagnostic criteria in the Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (DSM-5) may not capture the full range of depressive symptoms of some men who adhere to hegemonic masculine gender role norms. The purpose of this study was to examine the ability of several proposed externalizing variables to predict masculine depression in a sample of men (n = 169). A stepwise multiple regression process was used, in which three models were analyzed. The analysis indicated that hostility and anger were the only variables predictive of masculine depressive symptoms. Additional implications for clinical …

Trust In Science And Scientists And The Acceptance Of Evolution, Louis S. Nadelson, Kimberly K. Hardy

Psychological Sciences Faculty Publications and Presentations

Background: Accepting the concept of evolution is important for the advancement of biological science and has many implications for daily life. However, a large portion of the general public does not currently accept biological evolution. Therefore, it is important to understand what factors are associated with a decline in the acceptance of evolution. Of particular interest for us is the relationship of individuals’ sense of trust in science in relationship to evolution acceptance.

Methods: Using the Trust in Science and Scientists and Inventory of Student Evolution Acceptance we surveyed 159 undergraduate students enrolled in an introductory psychology course. Additionally, we …

Daily Activity Patterns Of 2,316 Men And Women From Five Countries Differing In Socioeconomic Development, Mamane Sani, Roberto Refinetti

Psychological Sciences Faculty Publications and Presentations

Daily rhythmicity in the locomotor activity of laboratory animals has been studied in great detail for many decades, but the daily pattern of locomotor activity has not received as much attention in humans. We collected waist-worn accelerometer data from more than 2,000 individuals from five countries differing in socioeconomic development and conducted a detailed analysis of human locomotor activity. Body mass index was computed from height and weight. Individual activity records lasting 7 days were subjected to cosinor analysis to determine the parameters of the daily activity rhythm: mesor (mean level), amplitude (half the range of excursion), acrophase (time of …

Dosing-Time Dependent Effects Of Sodium Nitroprusside On Cerebral, Renal, And Hepatic Catalase Activity In Mice, Mamane Sani, Hichem Sebai, Roberto Refinetti, Mohan Mondal, Néziha Ghanem-Boughanmi, Naceur A. Boughattas, Mossadok Ben-Attia

Psychological Sciences Faculty Publications and Presentations

To investigate the time dependence of sodium nitroprusside- (NPS-) induced oxidative effects, the authors study the variation of the antioxidant enzyme CAT activity in various tissues after the administration of a single 2.5mg/kg dose of SNP or sodium chloride (NaCl 0.9%). For each of the two dosing times (1 and 13 hours after light onset, HALO, which correspond to the beginning of diurnal rest span and of nocturnal activity span of mice, resp.), brain, kidney, and liver tissues were excised from animals at 0, 1, 3, 6, 9, 12, 24, and 36 h following the drug administration and CAT activity …

Mending Broken Fences, Mary E. Pritchard

Psychological Sciences Faculty Publications and Presentations

Tears streamed freely down my face as I watched waves crash on the beach.

My husband put his arms around me. "For what it's worth," he said, "I'm sorry this is happening to us."

So was I. We'd been through so much in our twenty-one years together: the loss of both of our fathers and two dogs, six surgeries for my endometriosis, four failed rounds of fertility treatments, the loss of his job thirteen years prior that had placed all our financial burdens squarely on my shoulders. Despite—or maybe because of—all of these things, I knew my marriage was over.

Relationships1 Among Applications Of Tacit Knowledge And Transformational/Transactional Leader Styles: An Exploratory Comparison Of The Mlq And Tkml, Teresa Z. Taylor, Joseph Psotka, Peter Legree

Psychological Sciences Faculty Publications and Presentations

Purpose: The purpose of this research is to examine intercorrelational relations among the self-report behavioral construct Multifactor Leadership Questionnaire (MLQ) 5X transformational and transactional subscales and the Tacit Knowledge for Military Leaders Inventory (TKML) leader-level specific situational judgment test scenarios.

Design/methodology/approach: Two leadership measures, the behavioral construct Multifactor Leadership Questionnaire (MLQ) and the cognitive construct Tacit Knowledge for Military Leaders Inventory (TKML) assess different aspects of how a leader functions and were administered to 125 active US Army officers representing three leader levels: platoon, company, and battalion. We examine the intercorrelational relationship between these two measures.

Findings: Results show a …

Media Influence On Drive For Thinness And Drive For Muscularity, Mary Pritchard, Brooke Cramblitt

Psychological Sciences Faculty Publications and Presentations

The present study investigated relationships between media influence (exposure, self-comparison to media ideals and internalization of media messages, societal pressure to have the perfect body, using media as a source of information about how to achieve a certain body ideal) and drive for thinness and drive for muscularity in 311 male and female undergraduates at a university in the Rocky Mountain region of the United States. We hypothesized that drive for thinness and drive for muscularity in both women and men would relate to body comparison/internalization, societal pressure, use of media for information, magazine consumption and television viewing. We also …

Do Body Image Investment And Evaluation Relate To Bulimic Symptoms In U.S. Collegiate Men And Women In The Same Way?, Mary E. Pritchard

Psychological Sciences Faculty Publications and Presentations

Although research suggests that body image investment (i.e., drive for muscularity, orientation toward appearance, preoccupation with weight or weight gain) and body image evaluation factors (e.g., negative evaluations of appearance, overestimation of current weight) correlate with bulimic symptoms, the magnitude of these relationships may differ between men and women. The relationship between bulimic symptoms and the drive for muscularity, one form of body image investment theorized to be particularly relevant to men, is understudied in college students. This study examined bulimic symptoms, body image investment, and body image evaluation in American undergraduate students (84 men, 198 women). Bulimic symptoms were …

Measuring Fragmentation In Dissociative Identity Disorder: The Integration Measure And Relationship To Switching And Time In Therapy, M. Rose Barlow, James A. Chu

Psychological Sciences Faculty Publications and Presentations

Background: Some people with dissociative identity disorder (DID) have very little communication or awareness among the parts of their identity, while others experience a great deal of cooperation among alternate identities. Previous research on this topic has been sparse. Currently, there is no empirical measure of integration versus fragmentation in a person with DID. In this study, we report the development of such a measure.

Objective: The goal of this study was to pilot the integration measure (IM) and to address its psychometric properties and relationships to other measures. The IM is the first standardized measure of integration in DID. …

What Predicts Drive For Muscularity In Collegiate Athletes V. Non-Athletes?, Mary Pritchard, Alli Nielsen

Psychological Sciences Faculty Publications and Presentations

In the past decade, research has begun to focus not only on dieting and exercise to lose weight, but dieting and exercise to gain muscle mass (drive for muscularity; DFM). While research has established that men tend to exhibit greater levels of DFM than women, little research has examined the influence of athletic status on drive for muscularity in male and female college students. This present study surveyed 290 student participants (30 female athletes, 38 male athletes, 139 female non-athletes, 82 male nonathletes and asked them about their DFM, as well as factors known to relate to DFM. As expected, …

Media's Influence On The Drive For Muscularity In Undergraduates, Brooke Cramblitt, Mary Pritchard

Psychological Sciences Faculty Publications and Presentations

Although research has found that body ideals presented by the media influence women's body dissatisfaction, less is known about media's influence on men's body satisfaction. An online survey examining media use, the drive for muscularity, and internalization of appearance and body shape ideals was given to a sample of 311 participants comprised of both men and women. Results indicated (a) the more time men and women reported watching television, the higher their reported drive for muscularity (b) total hours of viewing sports-related, image-focused, and entertainment television related to increased drive for muscularity in women (c) drive for muscularity in men …

The Concomitant Relationship Shared By Sleep Disturbances And Type 2 Diabetes: Developing Telemedicine As A Viable Treatment Option, Pennie S. Seibert, Jennifer Valerio, Codieann Dehaas

Psychological Sciences Faculty Publications and Presentations

Individually, sleep disturbances and type 2 diabetes pose pervasive challenges to health. In addition, the negative symptomology associated with each condition is exacerbated further when presenting concomitantly. This relationship formulates a destructive loop wherein those with diabetes experience decreased sleep quality, which, in turn, worsens a wide range of health threats experienced by those with diabetes, including obesity and glucose intolerance. Because major lifestyle changes and daily care are needed to effectively manage both diabetes and sleep disturbances, an efficient and timely modality of treatment is essential. Advanced technology incorporating telemedicine and telehealth has the potential to enhance treatment by …

Factors And Convergent Validity Of The Pet Attachment And Life Impact Scale (Pals), Lisa Demarni Cromer, M. Rose Barlow

Psychological Sciences Faculty Publications and Presentations

Human-animal interaction (HAI) provides benefits for humans. Emotional attachment to pets is a possible mechanism for benefits but there is no standard operationalization for “attachment to pets.” The study presented here (N = 651) uses a pet attachment measure based on qualitative research about benefits of pets. This measure, the Pet Attachment and Life Impact Scale (PALS), has four factors that measure Love, Regulation, Personal Growth, and Negative Impacts. We present exploratory factor analysis and confirmatory factor analysis of the instrument. We then examine convergent validity with four a priori derived measures of pet attachment (Anthropomorphism Scale, CENSHARE PAS, …

Classroom Level Effects Of Children’S Prior Participation In Child Care, K. Alison Clarke-Stewart, Rachel Lucas-Thompson, Jennifer M. Weaver, Andrea Karsh

Psychological Sciences Faculty Publications and Presentations

Previous research indicates that children who spend many hours in early child care exhibit more externalizing behavior problems than children who spend less time in child care. Concern has been expressed regarding the cumulative effect of these problem behaviors on elementary school classes. We collected information about children’s child-care histories from parents of first through fourth graders (N = 429) and about classroom functioning from their teachers (N = 31). We analyzed associations between the proportion of children in the class who had spent many hours in care prior to school entry and teachers’ reports of the time …

A Police Officer’S Tacit Knowledge Inventory (Potki): Establishing Construct Validity And Exploring Applications, T. Z. Taylor, P. Elison-Bowers, E. Werth, E. Bell, J. Carbajal, K. B. Lamm, Efren A. Velazquez

Psychological Sciences Faculty Publications and Presentations

Research summarizes the construction of a Police Officer’s Tacit Knowledge Inventory (Inventory), a situational judgment test comprised of knowledge gained on-the-job by experienced police officers, and examines if it can play a role in the development of expertise. Correlation and regression analysis was done to establish the Inventory’s ability to predict post-Academy graduation performance. Results show that Inventory response patterns correlate with Supervisor ratings; and the Inventory responses correctly predict significant differences between novice patrol officers and experienced police officers.

Analysis Of Gender Differences In Self-Statements And Mood Disorders, Robert Devore, Mary E. Pritchard

Psychological Sciences Faculty Publications and Presentations

Over 25% of adult Americans suffer from a mental disorder each year, with depression and anxiety being some of the most commonly reported issues. Researchers estimate that between 10% and 50% of adult Americans will suffer from a depressive episode at some point in their life, and cognitive theorists argue that mental states, including disorders, are generated and maintained by personal, subjective beliefs, and that events can only be appropriately labeled by the individual experiencing them. Thus, cognitive theorists suggest a strong link between self-talk (ST) and behavior and note that the automatic use of ST is associated with disordered …
