The microbiome‐gut‐brain and social behavior

AbstractThis paper argues for the sociological relevance of contemporary research from ‘relational’ or ‘systems’ biology on the microbiome‐gut‐brain (MGB) axis. I review research on the MGB from microbial neuroendocrinology, nutritional psychiatry and other fields with a specific focus on nutrition as a critical element of the social environment influencing gene‐environment interactions and a range of social behaviors. I discuss two plausible causal pathways from nutritional factors such as dietary inflammatory potential and hypocholesterolemia to social bonding, violence, and political extremism, and conclude with a discussion of the theoretical, methodological, and epistemological implications of these pathways, and of MGB research and relational biology generally, for social science.

Distinct evolutionary trajectories of V1R clades across mouse species

BackgroundMany animals rely heavily on olfaction to navigate their environment. Among rodents, olfaction is crucial for a wide range of social behaviors. The vomeronasal olfactory system in particular plays an important role in mediating social communication, including the detection of pheromones and recognition signals. In this study we examine patterns of vomeronasal type-1 receptor (V1R) evolution in the house mouse and related species within the genus Mus. We report the extent of gene repertoire turnover and conservation among species and clades, as well as the prevalence of positive selection on gene sequences across the V1R tree. By exploring the evolution of these receptors, we provide insight into the functional roles of receptor subtypes as well as the dynamics of gene family evolution.ResultsWe generated transcriptomes from the vomeronasal organs of 5 Mus species, and produced high quality V1R repertoires for each species. We find that V1R clades in the house mouse and relatives exhibit distinct evolutionary trajectories. We identify putative species-specific gene expansions, including a large clade D expansion in the house mouse. While gene gains are abundant, we detect very few gene losses. We describe a novel V1R clade and highlight candidate receptors for future study. We find evidence for distinct evolutionary processes across different clades, from largescale turnover to highly conserved repertoires. Patterns of positive selection are similarly variable, as some clades exhibit abundant positive selection while others display high gene sequence conservation. Based on clade-level evolutionary patterns, we identify receptor families that are strong candidates for detecting social signals and predator cues. Our results reveal clades with receptors detecting female reproductive status are among the most conserved across species, suggesting an important role in V1R chemosensation.ConclusionAnalysis of clade-level evolution is critical for understanding species’ chemosensory adaptations. This study provides clear evidence that V1R clades are characterized by distinct evolutionary trajectories. As receptor evolution is shaped by ligand identity, these results provide a framework for examining the functional roles of receptors.

Association of oxytocin receptor gene polymorphisms with autism spectrum disorder in Bengali of Bangladesh population

Autism spectrum disorder (ASD) is a group of sex-biased neurodevelopmental disorders characterized by core deficits in social interaction, communication and behaviors. Several lines of evidence indicate that oxytocin signaling through its receptor (OXTR), is vital in a wide range of social behaviors and role of OXTR polymorphism in ASD development has also been established in several populations. Therefore, an attempt was taken to determine whether genetic variations in the oxytocin signaling system contribute to ASD susceptibility in a part of Bangladeshi (BEB) population. We have investigated the role of OXTR polymorphisms (rs53576, rs2254298, rs2228485 and rs237911) in ASD development through PCR-RFLP method, based on case studies. A significant frequency (p = 0.027) for OXTR ‘rs53576AA’ risk genotype was found to be associated with ASD which is consistent with the previous study in Chinese but Caucasian and Japanese population. Besides, no significant association has been found for other OXTR variants (rs2254298, rs2228485 and rs237911) in this study. Understanding of these significant association with ASD development could be open a new clue aimed at clinical marker development for ASD diagnosis and treatment in future.

Resolving uncertainty in a social world.

Consider the range of social behaviours we engage in every day. In each case, there are a multitude of unknowns, reflecting the many sources of uncertainty inherent to social inference. We describe how uncertainty manifests in social environments (the thoughts and intentions of others are largely hidden, making it difficult to predict a person's behaviour) and why people are motivated to reduce the aversive feelings generated by uncertainty. We propose a three-part model whereby social uncertainty is initially reduced through automatic modes of inference (such as impression formation) before more control-demanding modes of inference (such as perspective-taking) are deployed to narrow one's predictions even more. Finally, social uncertainty is attenuated further through learning processes that update these predictions based on new information. Our framework integrates research across fields to offer an account of the mechanisms motivating social cognition and action, laying the groundwork for future experiments that can illuminate the impact of uncertainty on social cognition.

Female psychopharmacology matters! Towards a sex-specific psychopharmacology.

There is increasing recognition that women have a higher prevalence of certain psychiatric illnesses, and a differential treatment response and course of illness compared to men. Additionally, clinicians deal with a number of disorders like premenstrual syndrome, premenstrual dysphoric disorder, and postpartum depression, which affect women specifically and for which treatment and biological pathways are still unclear. In this article we highlight recent research which suggests that different biological mechanisms may underlie sex differences in responsiveness to stress. Sex differences are evident at the receptor level; where the corticotropin-releasing factor receptor shows differential coupling to adaptor proteins in males and females. The neuropeptide oxytocin also shows sex-specific effects in a range of social behaviors. It may act as a biomarker in post-traumatic stress disorder where sex differences are evident. Studies in women using hormonal contraception show that some of these oxytocin-mediated effects are likely influenced by sex hormones. In female rats rapid changes in circulating progesterone levels are associated with exaggerated behavioral responses to mild stress and blunted responses to benzodiazepines that could be prevented by acute treatment with low-dose fluoxetine. Perceived barriers in research on women have hindered progress. The development of a sex-specific psychopharmacology as a basis for translating this type of research into clinical practice is vital to improve treatment outcomes for women.

Preschool Children and iPads: Observations of Social Interactions During Digital Play

ABSTRACTResearch Findings: Digital play is now commonplace in many young children’s lives, but not in preschool settings. This situation is likely due to the fact that the existent literature seldom highlights what digital play looks like, the various ways it can be situated, and what young children do when they play together with digital devices in the preschool setting. The present study addresses this limitation by providing a close examination of the social interactions of young children as they engage with different types of iPad apps and each other. Observational data of 20 dyads of children during digital play analyzed qualitatively revealed that children exhibited a range of social behaviors from competitive to collaborative as they engaged in 4 types of digital play: practice/task, exploratory, construction, and pretense. Forms of play and exhibited behaviors were shaped by interrelated factors of children’s individual characteristics and relationships, classroom culture and routines, adult views and actions, as well as aspects of the digital device itself. Practice or Policy: Selecting open-design apps, attending to digital play structures, and monitoring peer play more closely may lessen competition, enhance collaboration, and lead to more complex digital play.

The Impact of Emotions and Empathy-Related Traits on Punishment Behavior: Introduction and Validation of the Inequality Game.

In the prevention and resolution of conflicts in social contexts, an important step is to understand how different emotions and empathic traits are linked to punishment behaviors. Unfortunately, few paradigms exist to study these phenomena. Here, we developed the Inequality Game (IG) as an economic and verbal interaction paradigm in which participants are faced with an “unfair other” as opposed to a “fair other” and subsequently have the opportunity to engage in a range of social behaviors. These social behaviors include cooperative or competitive economic choices and nice or derogatory verbal behavior toward the unfair and fair other. Participants could thus engage in punishment or forgiveness behavior toward the unfair other as well as in cooperative or aggressive behavior toward the fair other. We validated the IG through multimodal measures comprising the assessment of personality traits, emotions (by means of facial expressions and self-reports), arousal (by means of skin conductance responses), physical effort (force exertion), and behavioral reactions. Second, we examined the influence of emotions and empathy-related traits on punishment behavior. With regard to emotions, we observed a positive relation between malicious joy and punishment behavior. This result highlights the role of reward-related mechanisms in favoring punishment behavior. In addition, different empathic traits had opposing effects on antisocial behavior. Whereas personal distress predicted aggressive verbal behavior, perspective taking and empathic concern predicted a reduction in punishment behavior. Empathic traits also modulated emotional experience and person evaluations, such that perspective taking was related to more positive affect (less frowning and more smiling) and a more favorable evaluation of the unfair other. The current data validate the IG, reveal that malicious joy is positively related to punishment behavior, and show that different types of empathic traits can have opposing effects on antisocial behavior as well as on related emotions and person evaluations.

The Effects of Acute Arginine Vasopressin Administration on Social Cognition in Healthy Males

The structurally similar neuropeptides and hormones oxytocin (OT) and arginine vasopressin (AVP) play significant and complex roles in modulating a range of social behaviours, including social recognition and bond formation. Although OT has well-known roles in facilitating prosocial behaviors and enhancing emotion recognition, AVP has received increasing interest for diverging effects on social cognition behaviour most notably in males. The current study aimed to determine whether AVP also modulates the ability to understand emotion. Using a randomised double blind procedure, 45 healthy young males received either an AVP or placebo nasal spray and completed the Reading the Mind in the Eyes Test (RMET). In contrast to previous findings, there were no significant differences observed in performance on the RMET between AVP and placebo groups, even after examining items separated by task difficulty, emotional valence, and gender. This study provides diverging evidence from previous findings and adds to the growing body of research exploring the influence of neuropeptide hormones in social behaviour. It demonstrates that in this sample of participants, AVP does not enhance the ability to understand higher order emotion from others. Implications and suggestions for future AVP administration studies are discussed.

AVPR1A Sequence Variation in Monogamous Owl Monkeys (Aotus azarai) and Its Implications for the Evolution of Platyrrhine Social Behavior

The arginine vasopressin V1a receptor gene (AVPR1A) has been implicated in increased partner preference and pair bonding behavior in mammalian lineages. This observation is of considerable importance for studies of social monogamy, which only appears in a small subset of primate taxa, including the Argentinean owl monkey (Aotus azarai). Thus, to investigate the possible influence of AVPR1A on the evolution of social behavior in owl monkeys, we sequenced this locus in a wild population from the Gran Chaco. We also assessed the interspecific variation of AVPR1A in platyrrhine species that represent a set of phylogenetically and behaviorally disparate taxa. The resulting data revealed A. azarai to have a unique genic structure for AVPR1A that varies in coding sequence and microsatellite repeat content relative to other primate and mammalian species. Specifically, one repetitive region that has been the focus in studies of human AVPR1A diversity, "RS3," is completely absent in A. azarai and all other platyrrhines examined. This finding suggests that, if AVPR1A modulates behavior in owl monkeys and other neotropical primates, it does so independent of this region. These observations have also provided clues about the process by which the range of social behavior in the Order Primates evolved through lineage-specific neurogenetic variation.

Characterization of pituitary–adrenocortical activity in the Malayan flying fox (Pteropus vampyrus)

Pituitary-adrenocortical and gonadal endocrine activity was investigated in a captive colony of Pteropus vampyrus, a highly social Old World fruit bat. Both cortisol and corticosterone were present in plasma, at a ratio of approximately 5:1, respectively. Glucocorticoid but not testosterone levels significantly increased prior to and concomitant with the evening active period. Restraint stress for 15-60 min resulted in a significant and rapid increase in plasma levels of adrenocorticotropic hormone (ACTH) and glucocorticoids. ACTH levels quickly returned to baseline following restraint whereas glucocorticoid levels remained elevated for at least 30 min after restraint ended. Plasma ACTH levels after stress were similar to levels reported after stress in other mammals. Stress-induced glucocorticoid levels were several-fold greater than those reported for most mammals. Restraint for 15 min significantly inhibited testosterone levels. Restraint stress did not affect hormone levels on the morning following restraint. Brief capture, handling, and release of the animals did not elicit increases in these hormones. The physiological responsiveness of the pituitary and adrenal glands, along with P. vampyrus's documented seasonality and range of social behaviors, makes these bats an excellent model for exploring the general physiology of the hypothalamic-pituitary-adrenal and hypothalamic-pituitary-gonadal axes, as well as social influences on these axes.

Using Social Stories to Enhance Behaviour in Children with Autistic Spectrum Difficulties

This paper describes teachers, parents and educational psychologists working together to meet the needs of children and young people with autistic spectrum difficulties in mainstream and special schools. It examines the impact on children's social behaviour of a two-session workshop for groups of parents/carers, teachers and learning support assistants about 'Social Stories' (Gray, 1994). It highlights the contribution that Social Stories can make to the management of a wide range of social behaviours, including inappropriate sexual behaviour, unsafe behaviour and obsessional behaviour. Issues raised by the use of Social Stories and their benefits for children with autistic spectrum difficulties are considered. The paper concludes by describing the developing diversity in the use of Social Stories and invites those working in the field to contribute to the body of information about their strengths and limitations.

Neurocognitive and social functioning in schizophrenia.

This cross-sectional study examined the relationships between neurocognitive and social functioning in a sample of 80 outpatients with DSM-III-R schizophrenia. The neurocognitive battery included measures of verbal ability, verbal memory, visual memory, executive functioning, visual-spatial organization, vigilance, and early information processing. Positive and negative symptoms were assessed with the Positive and Negative Syndrome Scale. A range of social behaviors were assessed using the Social Functioning Scale (SFS), the Quality of Life Scale (QLS), and a video-based test, the Assessment of Interpersonal Problem-Solving Skills (AIPSS). Social functioning as assessed by the SFS was unrelated to neurocognitive functioning. Poor cognitive flexibility was associated with low scores on the QLS and the AIPSS. Verbal ability and verbal memory were also significantly associated with the AIPSS. Visual-spatial ability and vigilance were associated with the sending skills subscale of the AIPSS. In this study, which used a wide range of neurocognitive tests and measures of community functioning and social problem solving, results support earlier research that suggests an association between certain aspects of neurocognitive functioning and social functioning.

Understanding Violence in Contemporary and Earlier Gangs: An Exploratory Application of the Theory of Reasoned Action

Although the theory of reasoned action has been quite successful in predicting a wide range of social behaviors, it has not been used in understanding the behavior of gangs. The purpose of this article is to review the theory of reasoned action, to demonstrate how it can be applied to understanding gang violence, and to illustrate its potential applicability to a pilot sample of contemporary and earlier gangs living in a large metropolitan community.

Social Mobility and Social Participation

This article examines the charts and tables contained in chapter 11 of Social Indicators, 1976 covering a wide range of social behavior under the general topic "Social Mobility and Social Participation." The topics covered include educational and occupational mobility, voting in national elections, volunteer work, charitable giving, participation in community organizations, views on religion, and feelings of anomie. Most readers will agree that this is a potpourri of topics but that all have bearing on the well-being of citizens. There would be less agreement on the significance of most of the indicators for public policy. The factual conclusions that can be drawn from the tables and charts are discussed and additional information from recent research on some of the topics is presented—particu— larly on educational and occupational mobility, voting and political behavior, and participation in community organizations.

Sex-Typed Language: The Production of Grammatical Cases

Sex role influences a diverse range of social behaviors. Since language behavior is central to social interaction, sex role was expected to influence language behavior. Since members of the two sexes experience varying biosocial realities, and since language is a system of communication about realities, language behavior of men and women was expected to differ. Case refers to a system of deep structure constructs which define the relational meaning of a nominal unit to the verb and any other nominal units within a simplex sentence. Hypotheses about cases were deduced from corresponding features of sex role behaviors and case categories. Cases and gender were measured from texts made from videotapes of teachers in classrooms. Reconstruction, a method of inserting grammatically and contextually implicit information into the verbal exchange and classifying the resulting communication into simplex sentences and lexical units, was used to process the language data. Women produced a significantly greater proportion of explicit participative cases than men, thus demonstrating their greater concern with internal psychological states. The greater involvement of men with implementation of action by means of objects was shown by their greater use of instrumental and source cases. Women used significantly more instances of the purposive case. Men produced a significantly greater proportion of objective cases, thus verbally emphasizing things and particularly things acted upon. Agentive and locative cases failed to yield a difference for case realizations by men and women. Implications and conclusions were discussed.
