	Author	Anderson, W.D.; Summers, C.H.
	Title	Neuroendocrine Mechanisms, Stress Coping Strategies, and Social Dominance: Comparative Lessons about Leadership Potential			Type	Journal Article
	Year	2007	Publication	The ANNALS of the American Academy of Political and Social Science	Abbreviated Journal	Ann Am Acad Polit Soc Sci
	Volume	614	Issue	1	Pages	102-130
	Keywords	social dominance – authoritarian – Five Factor Model – neurochemistry – neurotransmitters – leadership
	Abstract	The authors examine dominance and subordination in the social psychology, political science, and biology literatures. Using Summers and Winberg (2006) as a guide, the authors suggest that extreme dominance or subordination phenotypes--including social dominance orientation and right-wing authoritarianism--are determined by an organism's genetic predispositions, motivations, stress responses, and long-term hormone release and uptake states. The authors offer hypotheses about the likely neurochemical profiles for each of these extreme dominance and subordination phenotypes and suggest two designs that begin to test these hypotheses.

	Title	Collegial decision making based on social amplification leads to optimal group formation			Type	Journal Article
	Year	2006	Publication	Proceedings of the National Academy of Sciences of the United States of America	Abbreviated Journal	Proc. Natl. Acad. Sci. U.S.A.
	Volume	103	Issue	15	Pages	5835-5840
	Keywords	Animals; Blattellidae/physiology; Choice Behavior; Decision Making; Leadership; Social Behavior
	Abstract	Group-living animals are often faced with choosing between one or more alternative resource sites. A central question in such collective decision making includes determining which individuals induce the decision and when. This experimental and theoretical study of shelter selection by cockroach groups demonstrates that choices can emerge through nonlinear interaction dynamics between equal individuals without perfect knowledge or leadership. We identify a simple mechanism whereby a decision is taken on the move with limited information and signaling and without comparison of available opportunities. This mechanism leads to optimal mean benefit for group individuals. Our model points to a generic self-organized collective decision-making process independent of animal species.

	Title	A case of infanticide in a recently found gelada population in Arsi, Ethiopia			Type	Journal Article
	Year	1997	Publication	Primates	Abbreviated Journal	Primates
	Volume	38	Issue	1	Pages	79-88
	Keywords	heropithecus gelada – Infanticide – Male takeover – Leadership change
	Abstract	Abstract  There have been no reports of infanticide in wild gelada baboons and it has been argued that infanticide is not necessary in geladas, since the birth interval of female gelada can be shortened after takeover of a unit by a new leader male without infanticide. However, we observed an instance of infanticide in a newly-found wild gelada population in the Arsi Region of Ethiopia. After a leader male of the unit was severely wounded by a leopard attack, he was quite weakened. The second male of the unit, a young adult male, became the leader of the unit three weeks later, but the former leader continued to stay in the unit as a second male. After a week, two other adult males joined the unit which, therefore, came to include four adult males. The infanticide took place nine days later. The perpetrator was one of the immigrant males and he showed great interest in the mother of the unweaned victim infant. Although the perpetrator copulated with her after the infanticide, the usurper was found to own all three adult females after two weeks following the infanticide; i.e. the perpetrator could not own any female. The wounded former leader showed conspicuous protective behavior towards the victim's mother and the dead infant. One possible explanation for the occurrence of infanticide in this population of geladas is as follows. Gelada males in this area may be able to join units more easily to form multi-male units but then have shorter tenure in the units. Facing the unstable condition of units, they may sometimes engage in infanticide to increase their breeding opportunities, even before becoming a leader.

	Title	Leadership, consensus decision making and collective behaviour in humans			Type	Journal Article
	Year	2009	Publication	Philosophical Transactions of the Royal Society B: Biological Sciences	Abbreviated Journal	Phil. Trans. Biol. Sci.
	Volume	364	Issue	1518	Pages	781-789
	Keywords	* leadership * consensus decision making * collective behaviour * human group
	Abstract	This paper reviews the literature on leadership in vertebrate groups, including recent work on human groups, before presenting the results of three new experiments looking at leadership and decision making in small and large human groups. In experiment 1, we find that both group size and the presence of uninformed individuals can affect the speed with which small human groups (eight people) decide between two opposing directional preferences and the likelihood of the group splitting. In experiment 2, we show that the spatial positioning of informed individuals within small human groups (10 people) can affect the speed and accuracy of group motion. We find that having a mixture of leaders positioned in the centre and on the edge of a group increases the speed and accuracy with which the group reaches their target. In experiment 3, we use large human crowds (100 and 200 people) to demonstrate that the trends observed from earlier work using small human groups can be applied to larger crowds. We find that only a small minority of informed individuals is needed to guide a large uninformed group. These studies build upon important theoretical and empirical work on leadership and decision making in animal groups.

	Title	Dominance, leadership, and aggression: animal behavior studies during the Second World War			Type	Journal Article
	Year	1990	Publication	Journal of the History of the Behavioral Sciences	Abbreviated Journal	J Hist Behav Sci
	Volume	26	Issue	1	Pages	3-16
	Keywords	Aggression; Animals; Behavior, Animal; Dominance-Subordination; History, 20th Century; Leadership; Political Systems; Social Dominance; United States
	Abstract	During the decade surrounding the Second World War, an extensive literature on the biological and psychological basis of aggression surfaced in America, a literature that in general emphasized the significance of learning and environment in the origins of aggressive behavior. Focusing on the animal behavior research of Warder Clyde Allee and John Paul Scott, this paper examines the complex interplay among conceptual, institutional, and societal forces that created and shaped a discourse on the subjects of aggression, dominance, and leadership within the context of World War II. The distinctions made between sexual and social dominance during this period, distinctions accentuated by the threat of totalitarianism abroad, and the varying ways that interpretations of behavior could be negotiated attests to the multiplicity of interactions that influence the development of scientific research.

	Title	Reproduction in feral horses			Type	Journal Article
	Year	1975	Publication	Journal of Reproduction and Fertility. Supplement	Abbreviated Journal	J Reprod Fertil Suppl
	Volume		Issue	23	Pages	13-18
	Keywords	Age Factors; Animals; Female; Horses/physiology; Leadership; Male; Maternal Behavior; Population; Reproduction; Sexual Behavior, Animal; Social Dominance; Sucking Behavior
	Abstract	A behavioural study of feral horses was conducted on the Pryor Mountain Wild Horse Range in the western United States. All 270 horses on the Range were identified individually. The sex ratio was nearly balanced. Foal to adult female ratio was 43-2:100. Morality was concentrated among foals and old horses. Horses were organized as forty-four harem groups each with a dominant stallion, one to two immature stallions, one to three immature mares, one to three adult mares and their yearling and foal offspring, and 23 bachelor groups of one to eight stallions. Harem groups were quite stable year-round because of dominance and leadership by the stallions and group fidelity by mares and their offsring. Most changes occurred during the breeding season and involved immature females. Defeat of dominant stallions was infrequent. Immature males were tolerated because of their submissive behaviour. Bachelor stallion groups were inherently unstable. Mares came into heat after foaling in May/June, and were mated by harem stallions only.

	Title	Leader--Follower Effects in Resource Dilemmas: The Roles of Leadership Selection and Social Responsibility			Type	Journal Article
	Year	2008	Publication	Group Processes Intergroup Relations	Abbreviated Journal
	Volume	11	Issue	3	Pages	355-369
	Keywords	followers, leadership selection, resource allocations, resource dilemmas, social responsibility
	Abstract	Previous research on the allocation of scarce resources shows that when people are assigned labels of leader or follower in their group, leaders allocate more of the scarce resources to themselves than followers do. In three laboratory studies, we examine the idea that how people are selected for the leader role (i.e. election or appointment) determines whether leaders take more or equal shares (relative to followers) from a common resource. In a first experiment, we show that participants were more accepting of norm violating behavior by an appointed versus elected leader. In a second experiment, we show that when participants were assigned to a leader or follower role, allocations of appointed leaders differed significantly from those of elected leaders and followers, whereas there was no difference between the two latter conditions. Moreover, elected leaders were shown to feel more social responsibility than both appointed leaders and followers. In a final experiment, we show that when participants were primed with the concept of social responsibility (relative to a neutral condition) no difference in allocations between appointed and elected leaders emerged.
