Altered grooming responses to stress in rats exposed prenatally to ethanol

The effects of prenatal alcohol exposure on grooming, locomotion, and rearing in response to stress were examined in adult rats whose mothers consumed a liquid diet containing 35% ethanol-derived calories (EDC). Offspring of both pair-fed 0% EDC mothers and ad libitum chow-fed mothers were included as controls. In Experiment 1, females groomed more than males following placement into a novel test chamber, but no differences due to prenatal treatment were observed. Ethanol-exposed animals groomed more than controls following the stress of a forced 1-min swim (Experiment 2), but when rats tested in Experiment 1 were observed again after forced swim stress (Experiment 3), no differences due to prenatal treatment or sex were observed. Experiment 4 examined the effects of pretreatment with 1 mg/kg naloxone on novelty-induced grooming and as in Experiment 1 prenatal treatment did not affect grooming responses. Females again groomed significantly more than males and naloxone reduced grooming equally for all groups. The results suggest that novelty-induced grooming is a sex-influenced behavior, with females grooming more than males, and that animals exposed prenatally to alcohol and tested as adults may have altered responses to certain stressors (i.e., forced swim) under specific conditions. The altered grooming response of alcohol-exposed rats to swim stress can be eliminated by preexposing them to novelty stress.     

Children's relationships with nonparental adults: Sex-specific connections to early school success

This report asks, Do the social networks of six-year-old girls and boys differ? It then extends previously reported findings by asking, Do different groups of nonparental adults affect the early school success of boys vs girls? Data were collected from the mothers of 162 six-year-olds, using a standard procedure. The networks of boys and girls in one-parent and two-parent households are contrasted throughout the presentation of results. The composition of networks was quite similar for boys and girls, except that each group had more same-sex than opposite-sex peers. In analyses predicting early school success, the number of adult male relatives who took the child on outings away from home was positively related to the child's report card score. This effect, however, was restricted to the subgroup of one-parent (mother-only) boys. This had been predicted, based on knowledge that single-parent boys are the most at-risk subgroup in the sample, the effect of social network resources are known to be accentuated by environmental press, and male adults represent the most salient models for young boys.     

A component model for diagnosing and treating children who stutter

Nine components of stuttering and their distribution among 54 children who stutter are described. The components are arranged into a model that includes four neurologic components (attending disorder, auditory-processing disorder, sentence-formulation disorder, and oral-motor disorder) and five traditional components (high self-expectations, manipulative stuttering, disruptive communication environment, unrealistic parental expectations, and abnormal parental need for the child to stutter). Diagnostic and treatment usefulness of the model are discussed. Thirty-two of the children have been followed through component-based treatment and 12 mo post termination. Results indicate that treatment was successful with 27 (84%) of the 32 children. Only one child regressed during the 12 mo after treatment ended. These results suggest that treating the neurologic and traditional factors which disrupt fluency improves maintenance and carry-over.     

The use of (symmetry) group theory as a predictive tool for studying bimanual coordination

Symmetry groups-rules that connect different configurations of a given set of components-represent a compact means of coding for effects, a feature that is desirable in both model- and theory-building. The present study was designed to compare the effects of spatial orientation differences with the various other asymmetries (e.g., timing differences, handedness preferences, the direction of attention) that are accommodated by current models of bimanual coordination. The authors used symmetry groups to predict specific patterns of results. In 2 experiments, participants (N = 13, Experiment 1; N = 9, Experiment 2) coordinated the movements of differently oriented (1 downward and 1 upward) pendulum pairs at a low (0.62 Hz) or high (0.82 Hz) movement frequency to establish an in-phase or antiphase pattern. Consistent with previous results (P. G. Amazeen, E. L. Amazeen, & M. T. Turvey, 1998a), the downward-oriented pendulum tended to lead slightly. In contrast to the effects of other bimanual asymmetries, the downward-oriented pendulum lead was amplified at low frequencies. Although the results contradicted the predictions of existing models of bimanual coordination, they were consistent with predictions from symmetry group theory. In the discussion, the authors focus on the application of symmetry groups to both bimanual coordination and other phenomena with more complex symmetric structures.     

Effects of visual and auditory short-term memory tasks on the spatiotemporal dynamics and variability of postural sway

The authors measured postural sway while participants (N = 20 in each experiment) stood on a rigid or a compliant surface, with their eyes open or closed, and while they did or did not perform a short-term memory (STM) task. In Experiment 1, the STM stimuli were presented visually; in Experiment 2, the stimuli were presented auditorily. In both experiments, fine-scaled, mediolateral postural-sway variability decreased as the cognitive load imposed by the STM task increased. That effect was independent of support surface and vision manipulations. The spatiotemporal profile of postural sway was affected by both visual and auditory STM tasks, but to a greater degree by the auditory task. The authors discuss implications of the results for theories and models of postural control.     

Metaphors for God: Why and How Do Our Choices Matter for Humans? The Application of Contemporary Cognitive Linguistics Research to the Debate on God and Metaphor

This article explores and critiques conservative and liberal theological understandings of metaphor in light of the contemporary research in cognitive linguistics. This assessment is followed by a cognitive examination of the biblical metaphors for God, their unconscious entailments, an assessment of why certain metaphors are more effective than others, and a short discussion of the implications of this effectiveness.     

Anxiety and depression in adolescents in urban and rural China

The goal was to assess rates of anxiety and depression in adolescents in two areas of Zhejiang Province, China. A cross-sectional survey was carried-out using a self-report questionnaire developed for this study. Participants were middle school students (age range 13-16 years) in an urban and a rural setting. There were 1576 completed questionnaires. Symptoms of anxiety sufficient to interfere with enjoyment of life, relaxation, and sleep were common (48%, 40%, and 27%, respectively). School-related problems were the predominant sources of worry. One third reported a history of depression, 16% had at times felt life was not worth living, and 9% reported that they had attempted suicide. Girls were more likely to report symptoms of depression. Patterns of help-seeking showed reliance on friends and parents; only 1% had sought professional help. There were no significant differences in anxiety and depression between one-child and multisibling families.     

Practicing the Order of Widows: A New Call for an Old Vocation

This essay argues for a renewed institution of an ancient Christianpractice, the Order of Widows. Drawing on the Roman Catholictradition's recent writings on the elderly, particularly the1998 document from the Pontifical Council for the Laity entitled"The Dignity of Older People and their Mission in the Churchand in the World," I argue that we find within the Roman Catholictradition advocacy for a renewed understanding of the vocationof the elderly within the Church. Building on this, I then tracein the broadest of outlines some elements of what a renewalof the Order of Widows might look like. In doing so, it becomesclear how this new ecclesial practice addresses health issuesof older women (devaluation, marginalization, loss of voice,impoverishment, debilitation, loneliness, isolation, and euthanasia).More importantly, such a practice moves beyond principles todemonstrate a concrete alternative. As such it would providea powerful witness to the very culture the Church seeks to transform.     

The perceived vulnerability to disease scale: Cross-cultural measurement invariance and associations with fear of COVID-19 across 16 countries

Using cross-sectional data from N = 4274 young adults across 16 countries during the COVID-19 pandemic, we examined the cross-cultural measurement invariance of the perceived vulnerability to disease (PVD) scale and tested the hypothesis that the association between PVD and fear of COVID-19 is stronger under high disease threat [that is, absence of COVID-19 vaccination, living in a country with lower Human Development Index (HDI) or higher COVID-19 mortality]. Results supported a bi-factor Exploratory Structural Equation Modeling model where items loaded on a global PVD factor, and on the sub-factors of Perceived Infectability and Germ Aversion. However, cross-national invariance could only be obtained on the configural level with a reduced version of the PVD scale (PVD-r), suggesting that the concept of PVD may vary across nations. Moreover, higher PVD-r was consistently associated with greater fear of COVID-19 across all levels of disease threat, but this association was especially pronounced among individuals with a COVID-19 vaccine, and in contexts where COVID-19 mortality was high. The present research brought clarity into the dimensionality of the PVD measure, discussed its suitability and limitations for cross-cultural research, and highlighted the pandemic-related conditions under which higher PVD is most likely to go along with psychologically maladaptive outcomes, such as fear of COVID-19.
