According to the social intelligence hypothesis, relative neocortex size should be directly related to the degree of social complexity. This hypothesis has found support in a number of comparative studies of group size. The relationship between neocortex and sociality is thought to exist either because relative neocortex size limits group size or because a larger group size selects for a larger neocortex. However, research on primate social evolution has indicated that male and female group sizes evolve in relation to different demands. While females mostly group according to conditions set by the environment, males instead simply go where the females are. Thus, any hypothesis relating to primate social evolution has to analyse its relationship with male and female group sizes separately. Since sex-specific neocortex sizes in primates are unavailable in sufficient quantity, I here instead present results from phylogenetic comparative analyses of unsexed relative neocortex sizes and female and male group sizes. These analyses show that while relative neocortex size is positively correlated with female group size, it is negatively, or not at all correlated with male group size. This indicates that the social intelligence hypothesis only applies to female sociality.

The present research was conducted to study the relationship between professional ethics and social intelligence of college teachers. In this regard, a sample of 200 college teachers was aimlessly selected. Two questionnaires were chosen to collect data. The collected data were analysed through SPSS software and proper statistical methods like mean, t-test and Pearson Correlation coefficient were used. The results demonstrated that there is no significant difference in the professional ethics mean scores of male and female college teachers, i.e. both the groups measure similar to professional ethics. The study also admits that there is a significant correlation between the professional ethics and social intelligence of college teachers, which means that higher the professional ethics, higher will be the social intelligence and vice versa.

This paper is about the evolution of hominin intelligence. I agree with defenders of the social intelligence hypothesis in thinking that externalist models of hominin intelligence are not plausible: such models cannot explain the unique cognition and cooperation explosion in our lineage, for changes in the external environment (e.g. increasing environmental unpredictability) affect many lineages. Both the social intelligence hypothesis and the social intelligence–ecological complexity hybrid I outline here are niche construction models. Hominin evolution is hominin response to selective environments that earlier hominins have made. In contrast to social intelligence models, I argue that hominins have both created and responded to a unique foraging mode; a mode that is both social in itself and which has further effects on hominin social environments. In contrast to some social intelligence models, on this view, hominin encounters with their ecological environments continue to have profound selective effects. However, though the ecological environment selects, it does not select on its own. Accidents and their consequences, differential success and failure, result from the combination of the ecological environment an agent faces and the social features that enhance some opportunities and suppress others and that exacerbate some dangers and lessen others. Individuals do not face the ecological filters on their environment alone, but with others, and with the technology, information and misinformation that their social world provides.

The high levels of intelligence seen in humans, other primates, certain cetaceans and birds remain a major puzzle for evolutionary biologists, anthropologists and psychologists. It has long been held that social interactions provide the selection pressures necessary for the evolution of advanced cognitive abilities (the ‘social intelligence hypothesis’), and in recent years decision-making in the context of cooperative social interactions has been conjectured to be of particular importance. Here we use an artificial neural network model to show that selection for efficient decision-making in cooperative dilemmas can give rise to selection pressures for greater cognitive abilities, and that intelligent strategies can themselves select for greater intelligence, leading to a Machiavellian arms race. Our results provide mechanistic support for the social intelligence hypothesis, highlight the potential importance of cooperative behaviour in the evolution of intelligence and may help us to explain the distribution of cooperation with intelligence across taxa.

The Psychological Skills Inventory for Sport (PSIS; Mahoney, 1988) identifies certain psychological skills or characteristics possessed by successful athletes. However, little has been done to connect the PSIS with other variables that may have an impact on the athletes’ psychological skills. Therefore the purpose of this study was twofold. First, the psychometric properties of the PSIS for all subjects and by gender were determined. Second, the relationship between the PSIS, experience, practice commitment, and gender of collegiate skiers was examined. A random sample of 131 male and female collegiate skiers responded to the 45-item PSIS. Overall, the six PSIS subscales (anxiety, concentration, confidence, mental preparation, motivation, and team emphasis) demonstrated acceptable internal reliability (coeff. alpha = .69−.84). Results of a 4 × 3 × 2 (Experience × Practice Commitment × Gender) MANOVA and follow-up univariate F tests revealed a significant gender effect on the team emphasis subscale. Female collegiate skiers were more team oriented than male collegiate skiers and placed more importance on the social and affiliative aspects of being on a team than did their male counterparts.

The study aimed to identify the relationship between the prevailing social control methods and the level of ambition among secondary students. The researcher used the descriptive descriptive approach. In order to achieve the objective of the study, the questionnaire was used to determine the validity and persistence of the social control methods, consisting of (47) items divided into two areas (the first area: the penalties and the second field: the rewards), prepared by the researcher (2005) The study sample consisted of (367) male and female students from the Fourth Directorate of Amman. The results of the study showed that the most common methods of social control used in the field of penalties are: to punish you for the offenses you have committed. In the area of ​​charges, "promote your good behavior in front of students in public." The results also showed that the level of ambition among students was high, ). The results also showed that there is no relationship between the methods of social control and the level of ambition among students. There are statistically significant differences in the methods of social control due to the gender variable. The differences were in favor of males in penalties and in favor of females in rewards. The level of ambition is attributed Variable sex; females in all dimensions of the study for the benefit.

This research aims to examine the relationship between social intelligence (SI) and organisational commitment (OC) among male and female managers of boys’ and girls’ schools in the two Iranian cities of Kashmar and Khalilabad. The statistical population of the study included all the managers of the aforementioned schools in two cities, with a total of 204 people based on the information received from the local education bureaus. The study is based on the correlation method. Pearson’s correlation coefficient, multiple regressions and independent t-test were carried out using the Statistical Package for the Social Sciences software for data analysis. The results revealed that there was a relationship between SI and OC; meanwhile, SI could somehow predict and explain the alterations in OC. Also, there was a meaningful association between the subscale of patience and OC where patience had an impact on OC and its dimensions.   Keywords: Organisational commitment, affective commitment, continuance commitment, normative commitment, social intelligence.

AbstractThe aim of this research is to examine the relationship between social intelligence and loneliness of academics in the workplace. This study involves 326 (149 female/177 male) academics employed in various universities in Turkey and North Cyprus. The age average of participants is 39.09 years. In this study, the Loneliness at Work Scale (LAWS) and Tromso Social Intelligence Scale (TSIS) have been utilized. The data were analyzed using multiple regression and Pearson product-moment correlation coefficient analysis techniques. The findings showed that social information processing, social skills, and social awareness, which are the sub-dimensions of social intelligence, positively explained 26% of social deprivation. Social skills and social awareness positively explained 13% of social companionship. The findings also showed that the social information processing sub-dimension did not meaningfully explain social companionship.
