Human milk cortisol concentration predicts experimentally induced infant fear reactivity: moderation by infant sex

Little consideration has been given to the possibility of human infant development being shaped via lactocrine programming, and by breast milk cortisol levels specifically. Despite animal models indicating that glucocorticoid (GC) exposure via lactation might modify brain development and behavior, only one study has reported that milk cortisol levels were positively associated with infant negative affectivity, especially fearfulness and sadness—early emerging risk factors for internalizing difficulties such as anxiety. The aim of the current study was to investigate whether human milk cortisol is associated with mother‐reported fearfulness and experimentally induced infant fear reactivity. Mother‐infant dyads (n = 65) enrolled in the FinnBrain Cohort Study participated. Breast milk samples were obtained 2.5 months postpartum, and milk cortisol concentrations were ascertained using validated luminescence immunoassay methodology. Infant fear reactivity was assessed using maternal reports 6 months postpartum and in a laboratory 8 months postpartum. There was a significant interaction between infant sex and milk cortisol such that higher milk cortisol was related to higher infant fear reactivity in a laboratory setting in girls (β = 0.36, p = .04) but not in boys (β = ?0.15, p = .40). Milk cortisol was not associated with mother‐reported infant fearfulness. Results suggest that higher human milk cortisol concentrations are associated with elevated experimentally induced fear in infancy. Findings support lactocrine programming, and suggest that mothers may “communicate” vital information about stressful environments via cortisol contained in breast milk, shaping girls' early emotional reactivity.     

Aspects of Morality and Law Enforcement in Today’s Science in Post-Soviet Countries

Many reports independently confirm that even more than a quarter of a century after the collapse of the Soviet Union, the results of research and development in those countries that were under its influence are insufficient in comparison to the rest of the world. Given that human intelligence is not distributed unevenly and that science is a powerful driving force for the future of an economy, there is a hidden problem, which, if it can be resolved, may release great economic potential. The first generation of researchers from Armenia, Czech Republic, Georgia, Slovakia and Ukraine, who successfully completed their education after the political revolution, were surveyed. The survey revealed many similarities with regards to ethics, but that there is mounting evidence that the main cause of the current situation is the state of the local legal systems. The conclusion was drawn that a conceptual change in staffing within the relevant legal systems is required to release potential and stimulate wealth creation.     

Are there gender differences in cognitive reflection? Invariance and differences related to mathematics

ABSTRACT

Cognitive reflection is recognized as an important skill, which is necessary for making advantageous decisions. Even though gender differences in the Cognitive Reflection test (CRT) appear to be robust across multiple studies, little research has examined the source of the gender gap in performance. In Study 1, we tested the invariance of the scale across genders. In Study 2, we investigated the role of math anxiety, mathematical reasoning, and gender in CRT performance. The results attested the measurement equivalence of the Cognitive Reflection Test – Long (CRT- L), when administered to male and female students. Additionally, the results of the mediation analysis showed an indirect effect of gender on CRT-L performance through mathematical reasoning and math anxiety. The direct effect of gender was no longer statistically significant after accounting for the other variables. The current findings suggest that cognitive reflection is affected by numerical skills and related feelings.     

The use of religion in coping with grief among bereaved Malay Muslim parents

The purpose of this study is to explore the influence of religion on bereaved parents after the death of a child. Literature had attempted to understand how religiosity may influence parental grief both in positive and negative ways. However, this area is scarcely explored in the Malaysian context. This qualitative study involved 11 bereaved parents who lost their children due to accidents (n?=?9) and homicide (n?=?2). Open-ended questions that focused on the importance, activities, and role of religion in the grieving process among Malay parents were asked. According to the thematic analysis, some of the main themes found were that the bereaved parents described religion as a beneficial mechanism in helping them to adapt with their losses through various responses that indicated the perception that religion as a guidance. However, other than the positive impact, religiosity can also lead the bereaved parents to experience negative effects of using religion as a coping strategy. The influence of culture is prevalent in the current study as the theme of mystical belief and paranormal experiences were also reported. This study provides some professional implication from the possible use of religion in intervention.     

Interspecies transmission of emotional information via chemosignals: from humans to dogs (<Emphasis Type="Italic">Canis lupus familiaris</Emphasis>)

We report a study examining interspecies emotion transfer via body odors (chemosignals). Do human body odors (chemosignals) produced under emotional conditions of happiness and fear provide information that is detectable by pet dogs (Labrador and Golden retrievers)? The odor samples were collected from the axilla of male donors not involved in the main experiment. The experimental setup involved the co-presence of the dog’s owner, a stranger and the odor dispenser in a space where the dogs could move freely. There were three odor conditions [fear, happiness, and control (no sweat)] to which the dogs were assigned randomly. The dependent variables were the relevant behaviors of the dogs (e.g., approaching, interacting and gazing) directed to the three targets (owner, stranger, sweat dispenser) aside from the dogs’ stress and heart rate indicators. The results indicated with high accuracy that the dogs manifested the predicted behaviors in the three conditions. There were fewer and shorter owner directed behaviors and more stranger directed behaviors when they were in the “happy odor condition” compared to the fear odor and control conditions. In the fear odor condition, they displayed more stressful behaviors. The heart rate data in the control and happy conditions were significantly lower than in the fear condition. Our findings suggest that interspecies emotional communication is facilitated by chemosignals.     

Investigating How Test-Takers Change Their Strategies to Handle Difficulty in Taking a Reading Comprehension Test: Implications for Score Validation

This article investigates how test-takers change their strategies to handle increased test difficulty. An adult sample reported their test-taking strategies immediately after completing the tasks in a reading test. Data were analyzed using structural equation modeling specifying a measurement-invariant, ability-moderated, latent transition analysis in Mplus (Muthén & Asparouhov, 2011). It was found that almost half of the test-takers (47%) changed their strategies when encountering increased task-difficulty. The changes were characterized by augmenting comprehending-meaning strategies with score-maximizing and test-wiseness strategies. Moreover, test-takers' ability was the driving influence that facilitated and/or buffered the changes. The test outcomes, when reviewed in light of adjusted test-taking strategies, demonstrated a form of process-based validity evidence.     

Genetic Counseling in the Era of Genomics: What’s all the Fuss about?

As genomic sequencing becomes more widely available in clinical settings for diagnostic purposes, a number of genetic counseling issues are gaining precedence. The ability to manage these issues will be paramount as genetic and non-genetic healthcare professionals navigate the complexities of using genomic technologies to facilitate diagnosis and inform patient management. Counseling issues arising when counseling for diagnostic genomic sequencing were identified by four genetic counselors with 10 years of collective experience providing genetic counseling in this setting. These issues were discussed and refined at a meeting of genetic counselors working in clinical genomics settings in Melbourne, Australia. Emerging counseling issues, or variations of established counseling issues, were identified from the issues raised. Illustrative cases were selected where pre- and post-test genetic counseling was provided in clinical settings to individuals who received singleton or trio WES with targeted analysis. Counseling issues discussed in this paper include a reappraisal of how genetic counselors manage hope in the genomic era, informed consent for secondary use of genomic data, clinical reanalysis of genomic data, unexpected or unsolicited secondary findings, and trio sequencing. The authors seek to contribute to the evolving understanding of genetic counseling for diagnostic genomic sequencing through considering the applicability of existing genetic counseling competencies to managing emerging counseling issues and discussing genetic counseling practice implications.     

Adjustment Profiles of Low-Income Caregivers from the United States and South Africa: Contrasts and Commonalities

Although low-income parents living in under-resourced communities in the United States and around the world face challenges, many do well while others struggle in one or more areas of functioning. The present study examined patterns of adjustment among maternal caregivers living in the United States (US) (N?=?320) and South Africa (SA) (N?=?324). Cluster analyses across four domains of functioning representing both positive and negative adjustment and conducted within country revealed similar patterns of adjustment, with a majority of caregivers (37.8% in the US; 47.5% in SA) landing in a “holding steady” pattern, exhibiting good but not exceptional adjustment. Other patterns of adjustment (three additional in the US sample; two additional in the SA sample) showed elevated impairment in somatic complaints, problems with alcohol, or life satisfaction. In both the US and SA, support from family, friends, and neighbors differentiated the adjustment profiles. Further, both current stressors within and outside of the family and previous stressors including direct and indirect exposure to violence discriminated caregivers who were “holding steady” from those who were struggling in one or more domains. Additionally, across both countries, caregivers who were “holding steady” evidenced less avoidant coping. Implications of this work for fostering resilience among caregivers and their children are discussed.     

Agents of Prosociality: Agency Affirmation Promotes Mutual Prosocial Tendencies and Behavior Among Conflicting Groups

Members of conflicting groups are motivated to restore their ingroup's agency, leading to antisocial tendencies against the outgroup. The present research tested the hypothesis that affirming conflicting groups' agency would increase their members' mutual prosociality. The effectiveness of agency affirmation was demonstrated in three contexts of conflict between groups: Switzerland and the EU following the 2014 referendum (Study 1), Israelis and Palestinians (Study 2), and Israeli rightists and leftists (Study 3). Study 1 found that in a nonconflictual context Swiss participants prioritized their moral (prosocial) over agentic goals, yet in the context of conflict with the EU, they prioritized their agentic over moral goals. This “primacy‐of‐agency” effect, however, was eliminated once their ingroup's agency was affirmed. Studies 2 and 3 demonstrated the positive effect of agency affirmation on prosociality among Israelis referring to Palestinians and Israeli rightists and leftists referring to the adversarial political camp. This effect was mediated by group members' readiness to relinquish some power for the sake of morality. Pointing to the importance of the affirmation's specific content, Studies 2 and 3 demonstrated that morality affirmation failed to increase prosociality. As such, the present research puts forward a promising strategy to reduce hostility and promote prosociality between conflicting groups.
