Group virtue: the importance of morality (vs. competence and sociability) in the positive evaluation of in-groups.

Although previous research has focused on competence and sociability as the characteristics most important to positive group evaluation, the authors suggest that morality is more important. Studies with preexisting and experimentally created in-groups showed that a set of positive traits constituted distinct factors of morality, competence, and sociability. When asked directly, Study 1 participants reported that their in-group's morality was more important than its competence or sociability. An unobtrusive factor analytic method also showed morality to be a more important explanation of positive in-group evaluation than competence or sociability. Experimental manipulations of morality and competence (Study 4) and morality and sociability (Study 5) showed that only in-group morality affected aspects of the group-level self-concept related to positive evaluation (i.e., pride in, or distancing from, the in-group). Consistent with this finding, identification with experimentally created (Study 2b) and preexisting (Studies 4 and 5) in-groups predicted the ascription of morality, but not competence or sociability, to the in-group

The relationship between metabolic rate and sociability is altered by food-deprivation

Individuals vary in the extent to which they associate with conspecifics, but little is known about the energetic underpinnings of this variation in sociability. Group-living allows individuals to find food more consistently, but within groups, there can be competition for food items. Individuals with an increased metabolic rate could display decreased sociability to reduce competition. Long-term food deprivation (FD) may alter any links between sociability and metabolic rate by affecting motivation to find food. We examined these issues in juvenile qingbo carp Spinibarbus sinensis, to understand how FD and metabolic rate affect sociability. Like many aquatic ectotherms, this species experiences seasonal bouts of FD. Individuals were either: (i) food-deprived for 21 days; or (ii) fed a maintenance ration (control). Fish from each treatment were measured for standard metabolic rate (SMR) and tested for sociability twice: once in the presence of a control stimulus shoal and once with a food-deprived stimulus shoal. Control individuals ventured further from stimulus shoals over a 30-min trial, while food-deprived fish did not change their distance from stimulus shoals as trials progressed. Control fish with a higher SMR were least sociable. Well-fed controls showed decreased sociability when exposed to food-deprived stimulus shoals, but there was evidence of consistency in relative sociability between exposures to different shoal types. Results contrast with previous findings that several days of fasting causes individuals to decrease associations with conspecifics. Prolonged FD may cause individuals to highly prioritize food acquisition, and the decreased vigilance that would accompany continuous foraging may heighten the need for the antipredator benefits of shoaling. Conversely, decreased sociability in well-fed fish with a high SMR probably minimizes intraspecific competition, allowing them to satisfy an increased energetic demand while foraging. Together, these results suggest that FD – a challenge common for many ectothermic species – can affect individual sociability as well as the attractiveness of groups towards conspecifics. In addition, the lack of a link between SMR and sociability in food-deprived fish suggests that, in situations where group membership is linked to fitness, the extent of correlated selection on metabolic traits may be context-dependent

Paraklooramfetamiini mõju psühhomotoorsele aktiivsusele ja serotoniini ja dopamiini tasemetele septumis ja prefrontaalkorteksis erineva püsisotsiaalsusega loomadel

Social behaviour plays important role in many psychopathologies. Sociability has been shown to be a stable trait in animals and individual differences in sociability are related to 5-HT transmission in septum and prefrontal cortex. The aim of the current study was to investigate whether animals with different levels of sociability are differently affected by p-chloroamphetamine treatment. 5-HT, 5-HIAA and DA levels were measured in septum and PFC and locomotor activity was recorded. Although there was no difference in monoamine levels or locomotor activity between LS- and HS-animals after PCA treatment, our findings confirm previous research on the different neurodegenerative effect of PCA in different brain regions. PCA had stronger neurodegenerative effect in PFC as 5-HT and 5-HIAA levels there were lower than in septum

Do Parents' Social Skills Influence Their Children's Sociability?

This paper examines the effect of parents' social skills on children's sociability, using the U.S. National Longitudinal Survey of Youth 1979 (NLSY79). This survey, like some other national surveys, lacks detailed information on parents; to remedy this deficiency, we construct a measure of parents' "sociability" skills based on their occupational characteristics from the Dictionary of Occupational Titles (DOT). The sociability relationship varies across parents and children by gender, but remains statistically significant (especially between fathers and sons), even after controlling for a variety of other background characteristics.Social skills, Intergenerational correlations, Occupational characteristics

Dorm Spaces and Sociability

Physical spaces may significantly shape social interaction. This study has explored how the residential provisions (Dormitories) for students at IIM-Ahmedabad impact their social life. This paper adopted interpretive methods in order to explore the impact of physical space on sociability of students. Data was collected with the help of interviews and observations in order to explore and uncover the collective meaning imparted by the participants of research in understanding the impact of built spaces on sociability for the old campus and new campus dormitory residents of IIMA. Three narratives emerged from the collected data. First narrative focused on life in the dorm, second narrative focused on artifacts and how they influence the interaction among the students, and third narrative was built around the events in the dorm. Interpretive methods helped in drawing out participants’ meanings related to spaces of the old and new campus dormitories and their impact on sociability. The study explored the lifeworld of dorm residents within these spaces. The study finds that built space and the organization of artifacts in that space do make a significant difference in social life of the dorm residents of IIMA.

Predicting Effects of Personality Traits, Self-esteem, Language Class Risk-taking and Sociability on Chinese University EFL Learners' Performance in English

Although the interactive effects of different variables in language learning have increasingly become the focus of recent research, the interaction of such variables as personality traits, self-esteem, language class risk-taking and sociability has not been much investigated. Hence, the present study explored the predicting effects of these variables on Chinese EFL learners’ performance in English at the tertiary level. A 68-item survey involving 934 first-year undergraduate non-English majors revealed that: (1) the majority were moderately extroverted, moderately inclined to anxiety and fears, and moderately prone to be influenced by social desirability but tended to be dependent and gentle; the participants were moderately satisfied with themselves and believed they were good and worthy; and the majority were moderately risk-taking and sociable in English class, (2) personality traits, self-esteem, language class risk-taking and sociability were generally significantly correlated with one another and with the students’ performance in English, and (3) overall self-esteem, language class risk-taking, language class sociability, and two personality variables–P (psychoticism) and L (lie) proved to be powerful predictors for the students’ performance in English. As such, personality traits, self-esteem, language class risk-taking and sociability are important factors affecting language learning outcomes

Addressivity and Sociability in “Celtic Men”

This paper is part of a larger project which examines the sociable dimensions of computer-mediated communication in local newsgroups on the Internet. This paper, however, takes as its primary data a complete thread of eighty five messages posted to RumCom’s largest ISP specific newsgroup,\ud rumcom.local. The messages share the subject header “Celtic Men” and play off contributors ideas about regional aspects of masculinity and male sexuality. As a whole they provide a good example of both a specific culturally located example of developing communication and a more general example of newsgroup CMC. Using this case as our exemplar we shall hold up for examination three matters: how the technology and software supplied by RumCom influence the form of interaction within the newsgroup; how different types of addressivity are used by posters to manage their communication; and how the notion of sociability figures as a useful device to characterise the specific traits of newsgroup interaction

Overexpression of the type 1 adenylyl cyclase in the forebrain leads to deficits of behavioral inhibition

The type 1 adenylyl cyclase (AC1) is an activity-dependent, calcium-stimulated adenylyl cyclase expressed in the nervous system that is implicated in memory formation. We examined the locomotor activity, and impulsive and social behaviors of AC1+ mice, a transgenic mouse strain overexpressing AC1 in the forebrain. Here we report that AC1+ mice exhibit hyperactive behaviors and demonstrate increased impulsivity and reduced sociability. In contrast, AC1 and AC8 double knock-out mice are hypoactive, and exhibit increased sociability and reduced impulsivity. Interestingly, the hyperactivity of AC1+ mice can be corrected by valproate, a mood-stabilizing drug. These data indicate that increased expression of AC1 in the forebrain leads to deficits in behavioral inhibition

Emotions, Demographics and Sociability in Twitter Interactions

The social connections people form online affect the quality of information they receive and their online experience. Although a host of socioeconomic and cognitive factors were implicated in the formation of offline social ties, few of them have been empirically validated, particularly in an online setting. In this study, we analyze a large corpus of geo-referenced messages, or tweets, posted by social media users from a major US metropolitan area. We linked these tweets to US Census data through their locations. This allowed us to measure emotions expressed in the tweets posted from an area, the structure of social connections, and also use that area's socioeconomic characteristics in analysis. %We extracted the structure of online social interactions from the people mentioned in tweets from that area. We find that at an aggregate level, places where social media users engage more deeply with less diverse social contacts are those where they express more negative emotions, like sadness and anger. Demographics also has an impact: these places have residents with lower household income and education levels. Conversely, places where people engage less frequently but with diverse contacts have happier, more positive messages posted from them and also have better educated, younger, more affluent residents. Results suggest that cognitive factors and offline characteristics affect the quality of online interactions. Our work highlights the value of linking social media data to traditional data sources, such as US Census, to drive novel analysis of online behavior.Comment: International Conference on the Web and Social Media (ICWSM2016

Heterogeneous Stochastic Interactions for Multiple Agents in a Multi-armed Bandit Problem

We define and analyze a multi-agent multi-armed bandit problem in which decision-making agents can observe the choices and rewards of their neighbors. Neighbors are defined by a network graph with heterogeneous and stochastic interconnections. These interactions are determined by the sociability of each agent, which corresponds to the probability that the agent observes its neighbors. We design an algorithm for each agent to maximize its own expected cumulative reward and prove performance bounds that depend on the sociability of the agents and the network structure. We use the bounds to predict the rank ordering of agents according to their performance and verify the accuracy analytically and computationally
