Social organization and aggression within small groups of female siamese fighting fish,betta splendens

Small groups of female Siamese fighting fish were observed in an attempt to determine whether a dominance order exists in these fish. Each fish, in each group, was allocated a rank for each activity on each day of observation. The rankings for the number of bites of food from a restricted source, the number of displays, the order of attacks, and the number of attacks each showed a significant concordance from day to day. A significant concordance was also found between the rankings of the different parameters. These data show that a stable dominance order is formed when females are in small groups. The top-ranked fish engages in more mutual displays and single-fish displays with the second-ranked fish than with the bottom-ranked fish. Displays showed differences in duration dependent upon whether or not they resulted in an attack. These data are discussed in terms of the conflict hypothesis and are in agreement with Simpson [1968] concerning the use of that hypothesis.     

Rhesus plasma cortisol response at four dominance positions

Adrenocortical function and social behaviors were measured in 48 laboratory-born juvenile monkeys in stable (original) groupings at rest, in the same groupings in competition for drinking water, in newly formed groupings each composed of animals from the same original dominance position, and upon return to the original groupings, always in groups of four. In newly formed groupings, plasma cortisol measured higher with each step down in the new dominance hierarchy, the effect attenuating by day 8. Although the partial correlation between frequencies of hostility behavior and plasma cortisol level was low (r = 0.05) when holding fear constant, the partial correlation between cortisol and fear behaviors, holding hostility behavior constant, was 0.86. The data provide evidence that corticosteroid elevations during social stress are related to behavior suggestive of fear and not aggression and are dependent upon dominance rank, the level of dominance competition, and previous dominance history.     

Dominance,aggression, and the functional use of space in institutionalized female adolescents

This is a study of an institutionalized group of female adolescents observed for a nine-week period. These girls were observed to determine the characteristics of their dominance relations and how, in turn, this aspect of their social environment was related to use of their physical environment. Correlational analyses between observational and sociometric data suggested that dominance rank was based upon the frequency of being the recipient of a dominance act. Fewer dominance acts were initiated against higher ranking girls. Dominance ranking was not based upon frequency of initiating a dominance act towards others. Higher ranking girls were the ones most frequently observed alone in their own bedroom. Bedrooms were highly desiuable areas used for grooming (eg, setting hair, ironing clothes, putting on cosmetics, resting) as girls sought to gain popularity with the institution's male population. Comparison of results with findings in similar studies on male adolescents suggest some tentative generalizations as to sex difference in dominance and territoriality.     

The two faces of fearless dominance and their relations to vocational success

We tested Lykken’s (1995) theory that the personality trait of fearless dominance (FD) can result in positive or negative life outcomes depending on whether the socialization process was successful or not. We tested FD’s predictive and moderated relations with vocational success over a time interval of 4 years. We found that the relations between FD and change in income were moderated by level of education. When educational level was high (low), there was a positive (negative) relation between FD and change in income. Change in income mediated the relation between FA and vocational satisfaction. Finally, FD directly predicted vocational satisfaction after 4 years. Implications and limitations are discussed.     

Reactions to tokenism: The role of individual characteristics in shaping responses to token decisions

When only a handful of members from a disadvantaged group occupy positions of power, they are considered tokens. Previous research suggests that observers tend to consider tokenism as an egalitarian practice. Given its ambiguous nature, we hypothesized that reactions to tokenism would be shaped by individuals' sensitivity to inequality. In Study 1, we showed that women (vs. men) and individuals low (vs. high) on social dominance orientation differentiated more between a token and an egalitarian decision in the context of gender‐related practices. Similar findings were observed in Study 2, which involved gender and feminist identification as independent variables. Additional support, particularly for the role of social dominance orientation, was found in Study 3, which involved an ethnic token. Together, results demonstrate the role of individuals' chronic sensitivity to inequality in shaping their reactions to token practices. Theoretical and practical implications regarding the effect of tokenism on individuals' evaluations and responses to inequality are discussed. Copyright © 2016 John Wiley & Sons, Ltd.     

Intergroup threat,social dominance,and the malleability of ideology: The importance of conceptual replication

Consistent with the theory of malleable ideology, research has shown that, under intergroup threat, antiegalitarian individuals will exploit the malleable character of color blindness and strategically claim to be strong supporters of it. In three studies conducted in France, we found no support for this theory when measuring color blindness but strong support when using measures of laïcité, an ideology of secularism. Indeed, those who score low on social dominance orientation (SDO) were more likely to support laïcité than antiegalitarian individuals. However, a situational threat (Study 1), a symbolic threat experimentally induced (Study 2), and a perceived symbolic threat (Study 3) were all related to increased support for laïcité by people high in SDO, without affecting those low in SDO. Thus, laïcité is a malleable ideology that can be adopted by individuals having contrasting motivations, as color blindness in the United States. Implications for the role of exact and conceptual replications in the development of a psychological science are discussed.     

Too many Asians in universities? The effect of social dominance orientation on support for admissions limits

This paper tests the hypothesis that support for limits on the admission of Asian students into universities is motivated by people’s social motivation—namely, the desire to maintain the status hierarchy. Study 1 found that, among participants who evaluated a proposed limit to the number of Asian applicants admitted to universities, social dominance orientation (SDO) was positively related to policy support. Conversely, among participants who evaluated a proposed limit on White admits, SDO was negatively related to policy support. Study 2 found that the perceived threat of the group getting admitted at high rates explained differential support of policies that seek to limit group-specific admissions. In all, these findings suggest that attitudes toward changes in campus demographics may be rooted in a desire to maintain the status hierarchy.     

Social dominance and the disassociation between explicit and implicit representations of equality

This study tested whether social dominance orientation (SDO) predicted a conceptual disassociation between explicit (declarative or propositional) attitudes about equality and implicit (automatic or associative) views of how representative New Zealand Europeans and Maori are of the New Zealand nation (N = 48 Europeans). Explicitly stated attitudes framing equality in terms of procedural justice or meritocratic treatment were positively correlated with individual differences in the implicit tendency to view New Zealand Europeans as exclusively representative of New Zealand. This tendency to explicitly frame equality as based on individual merit and to implicitly favour the dominant (European) ethnic group as representative of the nation was observed only among people high in SDO. Our analysis provides novel support for the position that meritocratic ideology is malleable and may be employed by those high in SDO to frame concepts of equality and justice in ways that suit their desire for group‐based dominance.

Propension à discriminer à l’égard du genre et dominance sociale

This work aims to study the propensity to discriminate (PTD) (Dovidio & Helb, 2005 ; Tisserant, Wagner & Barth, 2010) against gender and other salient criteria in the working place, such as ethnic origin and religious background. More precisely, we investigated the link between PTD and the social dominance orientation (Sidanius & Pratto, 1999). 119 counsellors from French employment services answered a questionnaire dealing on concepts and attitudes towards social groups. Results show that social dominance, as a system of belief justifying social inequalities, generally predict the PTD of individuals, whatever the criterion of discrimination considered. The sex of counsellors can be considered as a moderating variable since females are less likely to accept inequalities than males do. We discuss the need for work and organizational psychologists to invest, alongside the managers, this field of research on equality, non-discrimination and diversity (ENDD).     

Perceived Conflict and Leader Dominance: Individual and Contextual Factors Behind Preferences for Dominant Leaders

Recent research finds that political candidates and leaders with dominant, masculine physical features are more preferred under conditions of conflict than of cooperation. Importantly, however, methodological limitations of past research have hindered the identification of whether this effect reflects that voters intuitively view (1) dominant leaders as more competent in solving problems of conflict, (2) nondominant leaders as more competent in solving problems of cooperation, or (3) both. In this article, we utilize recent advances in evolutionary psychology to form precise predictions on the nature of the underlying psychology and employ an unprecedented array of data types—including highly controlled experiments, natural experiments, and behavioral measures—to investigate the validity of these predictions. Using large approximately nationally representative surveys of 2,009 Poles and Ukrainians fielded during the Crimea crisis in 2014, we find that preferences for leader dominance are exclusively driven by the intuition that dominant leaders are better able to facilitate aggressive responses during social conflict and that these preferences are regulated by contextual conditions and individual predispositions related to such responses.
