Jonathan Lyons – Lyons, Jonathan. “Brothers.” Palaver: UNCW’s Interdisciplinary Journal, (2015).

Jonathan Lyons, Assistant Professor, College Core Curriculum Three brothers—eldest, middle, youngest—the middle brother bookended by two siblings who are cases of failures of birth control: • The eldest arrives in 1967; • he is 13 months ahead of the middle brother; • he is four years and nine months ahead of the youngest. Three brothers whose first home is located on Bryant Street in Waterloo, Iowa, said home being formerly the childhood home of the brothers’ mother. The eldest will later, as an adult, calculate the timing of his conception and learn that his mother, who was sixteen at the […]

Chris Boyatzis, Professor of Psychology A growing body of literature indicates a modestly positive association between religiosity and spirituality as predictors of psychological health (anxiety and depression), suggesting they serve as personal resiliency factors. The purpose of this study was to expand our understanding of the relationships among these constructs. Using Lazarus’s Transactional Model of Stress as a theoretical framework, we examined: (a) the extent to which spirituality and religiosity mediated and/or moderated the association between perceived stress and psychological health and (b) whether there was a moderated (religiosity) mediation (spirituality) between stress and health. The Perceived Stress Scale, Daily […]

Thelathia Young, Assistant Professor of Women’s and Gender Studies

At times, the academy seems devoid of justice because it emphasizes the cultivation of knowledge often denied to marginalized individuals and communities. As black queer feminist scholars doing praxis-driven theorizing from separate fields on the subject of black queer families and communities, we employ research methods that resist the dynamics of power and privilege that exist within normative researcher-participant exchanges. In this essay, we explore and highlight the ethical, justice-oriented, and dialogical relationship between researcher-scholars and research participants. Through story and theory, we illustrate and argue that autoethnographies and narrative interviews can act as epistemological excavation tools for both researchers and participants, as they become sites of individual and collective consciousness. Our work resists capitalist models of research and instead promotes a justice-oriented and community-derived building of knowledge.

Jennifer Silva, Assistant Professor of Sociology & Anthropology

Participation in extracurricular activities is associated with positive youth outcomes such as higher education attainment and greater future earnings. We present new analyses of four national longitudinal surveys of American high school students that reveal a sharp increase in the class gap in extracurricular involvement. Since the 1970s, upper-middle-class students have become increasingly active in school clubs and sport teams, while participation among working-class students has veered in the opposite direction. These growing gaps have emerged in the wake of rising income inequality, the introduction of pay to play programs, and increasing time and money investments by upper-middle-class parents in children’s development. These trends need to be taken into account in any new initiative to monitor mobility. They also present a challenge to the American ideal of equal opportunity insofar as participation in organized activities shapes patterns of social mobility.

Andrea Halpern, Professor of Psychology

The study of spontaneous and everyday cognitions is an area of rapidly growing interest. One of the most ubiquitous forms of spontaneous cognition is involuntary musical imagery (INMI), the involuntarily retrieved and repetitive mental replay of music. The present study introduced a novel method for capturing temporal features of INMI within a naturalistic setting. This method allowed for the investigation of two questions of interest to INMI researchers in a more objective way than previously possible, concerning (1) the precision of memory representations within INMI and (2) the interactions between INMI and concurrent affective state. Over the course of 4 days, INMI tempo was measured by asking participants to tap to the beat of their INMI with a wrist-worn accelerometer. Participants documented additional details regarding their INMI in a diary. Overall, the tempo of music within INMI was recalled from long-term memory in a highly veridical form, although with a regression to the mean for recalled tempo that parallels previous findings on voluntary musical imagery. A significant positive relationship was found between INMI tempo and subjective arousal, suggesting that INMI interacts with concurrent mood in a similar manner to perceived music. The results suggest several parallels between INMI and voluntary imagery, music perceptual processes, and other types of involuntary memories.

Jennie Stevenson, Assistant Professor of Psychology

Organismal performance directly depends on an individual’s ability to cope with a wide array of physiological challenges. For social animals, social isolation is a stressor that has been shown to increase oxidative stress. Another physiological challenge, routine locomotor activity, has been found to decrease oxidative stress levels. Because we currently do not have a good understanding of how diverse physiological systems like stress and locomotion interact to affect oxidative balance, we studied this interaction in the prairie vole (Microtus ochrogaster). Voles were either pair housed or isolated and within the isolation group, voles either had access to a moving wheel or a stationary wheel. We found that chronic periodic isolation caused increased levels of oxidative stress. However, within the vole group that was able to run voluntarily, longer durations of locomotor activity were associated with less oxidative stress. Our work suggests that individuals who demonstrate increased locomotor activity may be better able to cope with the social stressor of isolation.

Allen Tran – Tran, Allen L. “Rich Sentiments and the Cultural Politics of Emotion in Postreform Ho Chi Minh City, Vietnam.” American Anthropologist 117, no. 3 (2015) : 480-492.

Allen Tran, Assistant Professor of Sociology & Anthropology

Linking socioeconomic and personal transformations, recent scholarship on neoliberalism in East and Southeast Asia has examined the role of various emotional experiences in reconfiguring selfhood toward values of personal responsibility and self-care. However, studies rarely focus on how such experiences come to be understood as specifically emotional themselves. In this article, I examine the growing use of emotion (cam xuc)as a conceptual category to define the self and everyday life in a psychologistic idiom among middle-class residents of Ho Chi Minh City, Vietnam. While more established discourses of sentiment (tinh cam) define selfhood in relation to notions of obligation and care, the emerging model of emotion emphasizes individuated self-knowledge. However, instead of replacing sentiment, newer understandings of emotion have developed alongside and in relation to sentiment. In categorizing various feelings as explicitly “emotional” in nature, people participate in a self-fashioning project that cultivates an emotionally aware and expressive self that is informed by neoliberal sensibilities yet does not supplant socialist or Confucian models of selfhood. I argue that emotions are not only central to the subjective experience of the transition to a market-oriented economy but also that emotion as a category itself is a medium through which economic transformations reorganize selfhood more generally.

Peter G. Judge, Professor of Psychology & Animal Behavior

Previous research has suggested that several primate species may be capable of reasoning by exclusion based on the finding that they can locate a hidden object when given information about where the object is not. The present research replicated and extended the literature by testing 2 Old World monkey species, lion-tailed macaques (Macaca silenus) and a hamadryas baboon (Papio hamadryas), and 2 New World species, capuchin monkeys (Sapajus apella) and squirrel monkeys (Saimiri sciureus). The New World monkeys were tested on the traditional 2-way object choice task, and all 4 species were also tested on a more complex 3-way object choice task. In addition, the squirrel monkeys were tested on a 2-way object choice task with auditory information. The results showed that, whereas the Old World species were able to infer by exclusion on the 3-object task, some of the capuchin monkeys had difficulty on each of the 2- and 3-cup tasks. All but 1 of the squirrel monkeys failed to infer successfully, and their strategies appeared to differ between the visual and auditory versions of the task. Taken together, this research suggests that the ability to succeed on this inference task may be present throughout Old World monkey species, but is fragile in the New World species tested thus far.

Ruth Tincoff, Assistant Professor of Psychology

The lexicon of 6-month-olds is comprised of names and body part words. Unlike names, body part words do not often occur in isolation in the input. This presents a puzzle: How have infants been able to pull out these words from the continuous stream of speech at such a young age? We hypothesize that caregivers’ interactions directed at and on the infant’s body may be at the root of their early acquisition of body part words. An artificial language segmentation study shows that experimenter-provided synchronous tactile cues help 4-month-olds to find words in continuous speech. A follow-up study suggests that this facilitation cannot be reduced to the highly social situation in which the directed interaction occurs. Taken together, these studies suggest that direct caregiver-infant interaction, exemplified in this study by touch cues, may play a key role in infants’ ability to find word boundaries, and suggests that early vocabulary items may consist of words often linked with caregiver touches.

Peter G. Judge, Professor of Psychology & Animal Behavior

Motor planning is a relatively complex cognitive skill in which an actor modifies a behavior to anticipate the future consequences of the action. Studying motor planning in nonhuman primates may provide a better understanding of the roots of human planning abilities. In this study we presented capuchin monkeys (Sapajus apella) with a horizontal dowel baited on either the left or right end. A radial grasp on the dowel with the thumb facing toward the baited end would be the most efficient grip selection when bringing the dowel to one’s mouth and indicate motor planning. Ten of the 12 monkeys tested spontaneously used a radial grasp significantly more often than expected by chance. Results demonstrate a more ubiquitous expression of motor planning abilities than previously seen in capuchin monkeys. Adaptation of this method of testing may be useful in evaluating motor planning capacity in other primates.

Four studies were implemented in order to ascertain how men and women flirt with potential partners and which flirtatious actions are considered most effective. Study 1 (n = 40) and Study 2 (n = 60) sought to discover the actions that men and women, respectively, engage in to indicate romantic interest to a partner. Study 3 (n = 110) sought to determine which flirtatious acts from women are perceived as most effective by men. Women’s flirtations that suggest sexual access were expected to be rated as most effective. Study 4 (n = 222) sought to determine which flirtatious acts from men are perceived as most effective by women. Men’s flirtations that suggest emotional commitment and exclusivity were expected to be rated as most effective by women. The results were consistent with the hypotheses and are discussed in terms of prior research.

Peter G. Judge, Professor of Psychology & Animal Behavior

Reduced space can lead to crowding in social animals. Crowding increases the risk of agonistic interactions that, in turn, may require additional physiological defensive coping mechanisms affecting health. To determine the stress induced from increased social density in a group of nineteen baboons living in an indoor/outdoor enclosure, saliva cortisol levels and rates of anxiety-related behavior were analyzed across two unique crowding episodes. Initially, mean salivary cortisol levels when animals were restricted to their indoor quarters were compared to those when they also had access to their larger outdoor enclosure. Then, mean cortisol levels were compared before, during, and after two distinct crowding periods of long and short duration. Crowding resulted in significantly elevated cortisol during crowding periods compared to non-crowded periods. Cortisol levels returned to baseline following two crowding episodes contrasting in their length and ambient climate conditions. These cortisol elevations indicate greater metabolic costs of maintaining homeostasis under social stress resulting from reduced space. Self-directed behavior, conversely, was not reliably elevated during crowding. Results suggest that the potential for negative social interactions, and/or the uncertainty associated with social threat can cause physiological stress responses detected by salivary cortisol. Self-directed behavioral measures of stress may constitute inadequate indicators of social stress in colony-housed monkeys or represent subjective emotional arousal unrelated to hypothalamic-pituitary adrenal axis activation.

T. Joel Wade, Professor of Psychology

Mating intelligence is a fairly new construct with only limited empirical examination. Yet, previous research has found important implications for the construct’s role in mating behavior. The present study sought to expand the existing body of research on mating intelligence by investigating its relationship with self-esteem, self-perceived attractiveness, and mate selection. A sample of 195 participants (83 males and 112 females) completed a survey that incorporated measures of mating intelligence, self-esteem, and self-perceived attractiveness. Additionally, participants were asked to choose between an attractive and unattractive mate to take out on a date. Significant positive relationships between mating intelligence, self-esteem, and self-perceived attractiveness were found for both sexes. For males, mating intelligence predicted self-esteem over and above selfperceived attractiveness. Both males and females with higher mating intelligence were more likely to select the attractive mate to date. Self-perceived attractiveness predicted self-esteem for both sexes, but the relationship was stronger for males.

Jean Lamont, Visiting Assistant Professor of Psychology

Trait body shame impacts psychological health, but its influence on physical health heretofore has not been examined. While body shame may be expected to impact physical health through many mechanisms, this investigation tested whether trait body shame predicts physical health outcomes by promoting negative attitudes toward bodily processes, thereby diminishing health evaluation and ultimately impacting physical health. Correlational (Study 1, N=177) and longitudinal (Study 2, N=141) studies tested hypotheses that trait body shame would predict infections, self-rated health, and symptoms, and that body responsiveness and health evaluation would mediate these relationships. In Study 1, trait body shame predicted all three poor health outcomes, and body responsiveness and health evaluation mediated these relationships. Study 2 partially replicated these results while controlling for depression, smoking, and BMI, and longitudinal analyses supported the temporal precedence of trait body shame in the proposed model. Limitations and alternative pathways are discussed.

T. Joel Wade, Professor of Psychology

The present research examined how being described as a dancer affects Black and White men and women’s assessed mate value in two studies. Study 1 examined evaluations of men by women and study 2 examined evaluations of women by men. Based on prior research examining how dancers are perceived and how body movements affect social perceiver’s evaluations of others, men and women described as dancers were expected to receive better ratings. Additionally, race of the individual being assessed was not expected to have any impact on mate value ratings. The results were consistent with the hypotheses. Men and women described as dancers received higher ratings than men and women described as non-dancers. Static manipulations of dancing ability also lead to evolutionary theory based evaluations of men and women.

Aaron D. Mitchel, Assistant Professor of Psychology

Speech is inextricably multisensory: both auditory and visual components provide critical information for all aspects of speech processing, including speech segmentation, the visual components of which have been the target of a growing number of studies. In particular, a recent study (Mitchel and Weiss, 2014) established that adults can utilize facial cues (i.e., visual prosody) to identify word boundaries in fluent speech. The current study expanded upon these results, using an eye tracker to identify highly attended facial features of the audiovisual display used in Mitchel and Weiss (2014). Subjects spent the most time watching the eyes and mouth. A significant trend in gaze durations was found with the longest gaze duration on the mouth, followed by the eyes and then the nose. In addition, eye gaze patterns changed across familiarization as subjects learned the word boundaries, showing decreased attention to the mouth in later blocks while attention on other facial features remained consistent. These findings highlight the importance of the visual component of speech processing and suggest that the mouth may play a critical role in visual speech segmentation.

John David Penniman, Assistant Professor of Religious Studies

Cyprian’s Epistle 63 represents the earliest extant account of the proper meaning and administration of the eucharistic cup. Against a group of Christians who were taking only water, Cyprian argues that wine is necessary for the ritual to be effective. While there has been much discussion surrounding the biblical references marshaled by Cyprian to prove his point, this article explores the extent to which those references are inflected through lexical and conceptual categories relating to the medical usage of wine. Wine figured prominently in literature on illness, health, and healing that proliferated during the Roman Empire. This article locates Cyprian within that broader dynamic, and argues that his emphasis on the health-giving effects of the eucharistic cup in Ep. 63 reflects similar descriptions of the medicinal power of wine found in manuals of Roman medicine and other folklore traditions.

Aaron D. Mitchel, Assistant Professor of Psychology

The social-cognitive deficits associated with several neurodevelopmental and neuropsychiatric disorders have been linked to structural and functional brain anomalies. Given the recent appreciation for quantitative approaches to behavior, in this study we examined the brain-behavior links in social cognition in healthy young adults from a quantitative approach. Twenty-two participants were administered quantitative measures of social cognition, including the social responsiveness scale (SRS), the empathizing questionnaire (EQ) and the systemizing questionnaire (SQ). Participants underwent a structural, 3-T magnetic resonance imaging (MRI) procedure that yielded both volumetric (voxel count) and asymmetry indices. Model fitting with backward elimination revealed that a combination of cortical, limbic and striatal regions accounted for significant variance in social behavior and cognitive styles that are typically associated with neurodevelopmental and neuropsychiatric disorders. Specifically, as caudate and amygdala volumes deviate from the typical R > L asymmetry, and cortical gray matter becomes more R > L asymmetrical, overall SRS and Emotion Recognition scores increase. Social Avoidance was explained by a combination of cortical gray matter, pallidum (rightward asymmetry) and caudate (deviation from rightward asymmetry). Rightward asymmetry of the pallidum was the sole predictor of Interpersonal Relationships and Repetitive Mannerisms. Increased D-scores on the EQ-SQ, an indication of greater systemizing relative to empathizing, was also explained by deviation from the typical R > L asymmetry of the caudate.
