“…Whereas we found no negative effects of losing and copulation experiences on subsequent mate acquisition, Yasuda, Matsuo, Hasaba, and Wada (2014) has shown that for P. middendorffii, males with losing experience decrease their aggressiveness in maleemale contests only when they encounter a familiar winner. Furthermore, males of P. nigrofascia with copulation experience are more competitive in maleemale contests than males without copulation experience (Yasuda, Matsuo, & Wada, in press).…”

“…Although social status is largely influenced by either familial rank or intrinsic attributes, theoretical and empirical evidence suggests that emergent social properties also influence the ontogeny of dominance. The 'social dynamics' hypothesis posits that dominance ranks emerge from self-organization dynamics such as winner-loser effects or highly localized social network properties, even in the absence of individual differences in specific attributes [35,36,37]. Winner-loser effects are well-documented forms of learning in which victorious individuals subsequently behave more aggressively, whereas losers behave more submissively [38,39,40].…”

Aggression is ubiquitous among animals, and contest outcomes in many gregarious species yield societies structured by dominance hierarchies. Recent results from a variety of disciplines have laid the groundwork for an integrative view of aggression and dominance, ranging from their physiological underpinnings to their evolutionary histories. Here we use Tinbergen's four levels of behavioral analysis to summarize our current understanding of aggressive behavior and dominance relationships. First, we discuss the role of epigenetic effects in the ontogenetic emergence of aggressive and rank-related phenotypes, and summarize how these phenotypes are mediated by endocrine and nervous system activity. We briefly review recent work on the functions of aggression and dominance hierarchies in animal societies, and then consider their phylogenetic history. Finally, we review methodological encumbrances to the study of dominance, and consider the unique evolution of aggression and dominance relationships in humans.

Errors in decision-making in animals can be partially explained by adaptive evolution, and error management theory explains that cognitive biases result from the asymmetric costs of false-positive and false-negative errors. Error rates that result from the cognitive bias may differ between sexes. In addition, females are expected to have higher feeding rates than males because of the high energy requirements of gamete production. Thus, females may suffer relatively larger costs from false-negative errors (i.e. non-feeding) than males, and female decisions would be biased to reduce these costs if the costs of false-positive errors are not as high.Females would consequently overestimate their capacity in relation to the probability of predation success. We tested this hypothesis using the Japanese pygmy squid Idiosepius paradoxus. Our results show that size differences between the squid and prey shrimp affected predatory attacks, and that predatory attacks succeeded more often when the predator was relatively larger than the prey. Nevertheless, compared to male predatory attacks, female squid frequently attacked even if their size was relatively small compared to the prey, suggesting that the females overestimated their probability of success. However, if the females failed in the first attack, they subsequently adjusted their attack threshold: squid did not attack again if the prey size was relatively larger. These results suggest a sex-specific cognitive bias, that is females skewed judgment in decisionmaking for the first predation attack, but they also show that squid can modify their threshold to determine whether they should attack in subsequent encounters.
