UNASSIGNED: Food sociality refers to the exploration of food production, exchange, distribution, and consumption and influences on cultural communication and social meaning. This study aimed to investigate food sociality in three provinces of South China to provide theoretical and practical evidence of food sociality in the region and to revise nutrition policies.
UNASSIGNED: We conducted a qualitative study comprising 25 experts in the fields of nutrition, sociology, food science, and agriculture from Hainan, Guangdong, and Guangxi Province by using a semi-structured in-depth interview, which included 28 pre-determined questions covering six topics. The interviews were conducted between November 2020 and March 2021. Verbatim transcripts were analyzed thematically using NVivo 11.0.
UNASSIGNED: Of the 25 experts, the mean age was 50.6 (SD = 8.4) years, 15 (60%) were male, and 22 (88%) held a master\'s degree or above. The analysis showed that food sociality in three provinces of South China mainly comprises social functions of food and dietary behavior. Regarding social functions of food, the experts expressed that food represents local culture (72%, 18 experts), presents social status and economic power (40%, 10 experts), and is central to special occasions, traditional customs, and etiquette activities (60%, 15 experts). In terms of social functions of dietary behaviors, the majority of experts indicated that food is a social communication tool (72% experts), has geographical characteristics (80% experts), and, to some extent, is used as a proxy for reward or punishment. Furthermore, festivals are one of the core elements of food sociality in the region, although food safety is a major concern. Some dietary behaviors, such as overindulgence in afternoon tea and encouraging drinking, may increase the risk of chronic diseases.
UNASSIGNED: Food sociality in three provinces of South China is mainly related to the social function of food and dietary behavior. It is a combination of local culture, social status and economic power, traditional customs, rewards and punishments, geographical food preference, and social communication tools. The authors recommend increasing food safety at festivals and promoting healthy eating behaviors in order to improve the overall health of the population in this region.

Proximity and synchronous behaviours from surface observations have been used to measure association patterns within and between dolphin dyads. To facilitate an investigation of relationship quality in dolphins, we applied a method used for primates and ravens that examined three main components to describe relationships: value, security, and compatibility. Using pilot data from long-term research of two study populations for this preliminary assessment, these three components were extracted from PCA of eight behavioural variables with more than 80 % variance accounted for in both study groups. Only pair swim position differed between groups. Although value, security, and compatibility are abstract terms, each is based on behaviours identified as important in dolphin social life, at least for these two populations. Examining relationship quality in dolphins with a method used to illustrate dyadic differences for primates and ravens allows for a quantitative, comparative assessment of sociality across disparate taxa. Although these species are diverse in their anatomies and in their social habitats (e.g., aquatic, terrestrial, aerial), they may well share the basic societal building blocks in the factors affecting how relationships are formed. We discuss how an examination of these behavioural variables facilitates understanding relationship quality in dolphins, as well as how dolphin relationships fit into the context of social animals\' society.

Comparative behavioural studies help reconstruct the phylogeny of closely related species. In that respect, the serows Capricornis spp. occupy an important position as they have been assumed to be the closest forms to the ancestors of Caprinae. In spite of that, information on the behavioural repertoire of the mainland serow Capricornis sumatraensis is exceedingly poor. In this paper, we report data on the activity rhythms and social behaviour of rutting mainland serows in captivity (Central Thailand, January 1986; January-February 1987). Activity was bimodal with peaks in mid-afternoon and late night. Resting and ruminating peaked at noon and twilight. Four patterns of marking behaviour were observed out of a total of 1900 events. Males and females were found to use different marking sites and frequencies. A total of 33 social behaviour patterns were observed: 18 patterns concerned agonistic behaviour, whereas 15 patterns were relevant to courtship behaviour. A comparison across Caprinae species with unritualised piercing weapons (i.e., Capricornis, Naemorhedus, Rupicapra, Budorcas, and Hemitragus) has shown that inter-sexual direct forms of aggressive behaviour are used significantly more often than indirect ones, but for chamois, confirming Rupicapra spp. as the most advanced genus among them in terms of an early ritualisation of weapons. Conversely, horns of the goral Nemorhaedus spp. and the serow lie on the same plane of the frontal bones, thus making possible the usage of a dominance display through frontal pushing.

Recent evolutionary psychological theory proposes that loneliness is an adaptive mechanism, designed to trigger maintenance and repair of social ties. No population representative analyses have probed loneliness effects on sociality. The present study addressed this gap.
Data were from the 2006, 2010, 2014, and 2018 waves of the Health and Retirement Study, nationally representative of U.S. adults over age 50. Recently developed cross-lagged models with fixed effects were used to test prospective within-person associations of loneliness with specific dimensions of sociality, taking into account reverse causality as well as all time-invariant confounders with stable effects. Both gender-combined and -specific analyses were conducted.
Loneliness did not consistently predict overall sociality: sparse linkages were found only among women. The same null pattern held with family ties. Non-family ties, in contrast, were associated with prior loneliness, but in a gender-specific way. Loneliness positively predicted women\'s social interactions with friends, but seemed linked to withdrawal from these relationships among men. There were indications that lonely men instead used religious attendance as a social outlet.
Loneliness seems to induce domain- and gender-specific sociality responses. Findings suggest implications for evolutionary models of sociality as well as for psychosocial and physical health. Pending replication in independent samples, inferences remain tentative.

The relationship between the spatiotemporal distribution of resources and patterns of sociality is widely discussed. While the resource dispersion hypothesis (RDH) was formulated to explain why animals sometimes live in groups from which they derive no obvious benefits, it has also been successfully applied to species that benefit from group living. Some empirical tests have supported the RDH, but others have not, so conclusions remain equivocal and further research is required to determine the extent to which RDH predictions hold in natural systems. Here, we test four predictions of the RDH in an African lion population in the context of their fission-fusion society. We analyzed data on group composition of GPS-collared lions and patterns of prey availability. Our results supported the first and second predictions of the RDH: Home range size (a) was independent of group size and (b) increased with distance between encounters with prey herds. Nonetheless, the third and fourth RDH predictions were not supported: (c) The measure of resource heterogeneity and (d) resource patch richness measured through prey herd size and body size had no significant effect on lion group size. However, regarding the fourth prediction, we added an adaptation to account for dynamics of fission-fusion society and found that the frequency of pride fission increased as group size increased. Our data set restricted us from going on to explore the effect of fission-fusion dynamics on the relationship between group size and patch richness. However, this should be investigated in future studies as including fission-fusion dynamics provides a more nuanced, realistic appreciation of lion society. Our study emphasizes the importance of understanding the complexity of a species\' behavioral ecology within the framework of resource dispersion. Whatever larger theoretical framework may emerge to explain lion society, incorporating fission-fusion dynamics should allow the RDH to be refined and improved.

Children from multicultural families face physical, social, mental, and intellectual hurdles; however, relative interventions are lacking in South Korea (hereafter Korea) in this regard. The purpose of this study was to investigate the effects of regular Taekwondo (TKD) training on physical fitness, mood, sociability, and cognitive functions in these children.
This study included 30 children from multicultural families in Korea who were randomly assigned to a TKD group (n = 15) and control group (n = 15). The children in TKD group underwent 16 weeks of TKD training once a week for 60 min. Each participant underwent a basic fitness test and sociability questionnaire before and after the intervention. Furthermore, we examined the changes in the mood and cognitive function by determining the profile of mood states (POMS), and Stroop color and word test, respectively.
Results of the Stork test of balance were significantly higher in the TKD group after intervention (p < 0.05). In terms of sub-variables, POMS, tension, and depression scores were significantly lower (p < 0.05) after the intervention, while the vigor score was significantly higher in the intervention group than those in the control group (p < 0.05). Furthermore, sociability and \'being left out\' score, a sub-variable of sociability, was significantly lower (p < 0.05) after the intervention, while sociability score was significantly higher (p < 0.05).
Our findings suggest that participation in regular TKD training can be effective for balanced improvements in variables of basic fitness and that it exerts a positive effect on the mood and development of sociability.

Recreational running is increasingly widespread and could therefore be seen as the obvious target for those hoping to encourage greater public health through exercise. Existing qualitative research on this topic has, however, tended to focus on groups of highly committed runners. It is accordingly unclear whether their findings can be extrapolated to the much larger population of comparatively casual runners. This existing work has also tended to emphasise the social nature of the activity in particular ways. Whilst much recreational running happens alone, most commonly these studies have centred on the establishment of shared identities and group subcultures. Drawing on a study involving accompanied runs and interviews with recreational runners who do not belong to running clubs in London, this paper presents an alternative account. These respondents were relatively uninterested in the idea of proper running technique, ambivalent about the presence of others when running, and reticent about being pulled into a more committed collective practice. In view of how these more casual runners may be of particular interest to public health promoters, this finding suggests future campaigns might do well not to focus too greatly on the potential enjoyments of running community membership and start instead with a different set of social dynamics.

Efficient brain-computer interfaces (BCIs) are in need of knowledge about the human brain and how it interacts, plays games, and socializes with other brains. A breakthrough can be achieved by revealing the microfoundations of sociality, an additional component of the utility function reflecting the value of contributing to group success derived from social identity. Building upon our previous behavioral work, we conduct a series of functional magnetic resonance imaging (fMRI) experiments (N = 10 in the Pilot Study and N = 15 in the Main Study) to measure whether and how sociality alters the functional activation of and connectivity between specific systems in the brain. The overarching hypothesis of this study is that sociality, even in a minimal form, serves as a natural mechanism of sustainable cooperation by fostering interaction between brain regions associated with social cognition and those related to value calculation. We use group-based manipulations to induce varying levels of sociality and compare behavior in two social dilemmas: Prisoner\'s Dilemma and variations of Ultimatum Game. We find that activation of the right inferior frontal gyrus, a region previously associated with cognitive control and modulation of the valuation system, is correlated with activity in the medial prefrontal cortex (mPFC) to a greater degree when participants make economic decisions in a game with an acquaintance, high sociality condition, compared to a game with a random individual, low sociality condition. These initial results suggest a specific biological mechanism through which sociality facilitates cooperation, fairness and provision of public goods at the cost of individual gain. Future research should examine neural dynamics in the brain during the computation of utility in the context of strategic games that involve social interaction for a larger sample of subjects.

To help patients with autism spectrum disorder (ASD) improve their social skills, effective interventions and new treatment modalities are necessary. We hypothesized that a prosocial online game would improve social cognition in ASD adolescents, as assessed using metrics of social communication, facial recognition, and emotional words. Ten ASD adolescents underwent cognitive behavior therapy (CBT) using a prosocial online game (game-CBT), and ten ASD adolescents participated in an offline-CBT. At baseline and 6 weeks later, social communication quality, correct identification of emotional words and facial emoticons, and brain activity were assessed in both groups. Social communication quality and correct response rate of emotional words and facial emoticons improved in both groups over the course of the intervention, and there were no significant differences between groups. In response to the emotional words, the brain activity within the temporal and parietal cortices increased in the game-CBT group, while the brain activity within cingulate and parietal cortices increased in the offline-CBT group. In addition, ASD adolescents in the game-CBT group showed increased brain activity within the right cingulate gyrus, left medial frontal gyrus, left cerebellum, left fusiform gyrus, left insular cortex, and sublobar area in response to facial emoticons. A prosocial online game designed for CBT was as effective as offline-CBT in ASD adolescents. Participation in the game especially increased social arousal and aided ASD adolescents in recognizing emotion. The therapy also helped participants more accurately consider associated environments in response to facial emotional stimulation. However, the online CBT was less effective than the offline-CBT at evoking emotions in response to emotional words.
