Motivation To Participate

Dominant individuals differ from subordinates in their performances on cognitive tasks across a suite of taxa. Previous studies often only consider dyadic relationships, rather than the more ecologically relevant social hierarchies or networks, hence failing to account for how dyadic relationships may be adjusted within larger social groups. We used a novel statistical method: randomized Elo-ratings, to infer the social hierarchy of 18 male pheasants, Phasianus colchicus , while in a captive, mixed-sex group with a linear hierarchy. We assayed individual learning performance of these males on a binary spatial discrimination task to investigate whether inter-individual variation in performance is associated with group social rank. Task performance improved with increasing trial number and was positively related to social rank, with higher ranking males showing greater levels of success. Motivation to participate in the task was not related to social rank or task performance, thus indicating that these rank-related differences are not a consequence of differences in motivation to complete the task. Our results provide important information about how variation in cognitive performance relates to an individual's social rank within a group. Whether the social environment causes differences in learning performance or instead, inherent differences in learning ability predetermine rank remains to be tested.

Males And Females

Abstract Females and males often face different sources of selection, resulting in dimorphism in morphological, physiological, and even cognitive traits. Sex differences are often studied in respect to spatial cognition, yet the different ecological roles of males and females might shape cognition in multiple ways. For example, in dietary generalist bumblebees (Bombus), the ability to learn associations is critical to female workers, who face informationally rich foraging scenarios as they collect nectar and pollen from thousands of flowers over a period of weeks to months to feed the colony. While male bumblebees likely need to learn associations as well, they only forage for themselves while searching for potential mates. It is thus less clear whether foraging males would benefit from the same associative learning performance as foraging females. In this system, as in others, cognitive performance is typically studied in lab-reared animals under captive conditions, which may not be representative of patterns in the wild. In the first test of sex and species differences in cognition using wild bumblebees, we compared the performance of Bombus vancouverensis nearcticus (formerly bifarius) and Bombus vosnesenskii of both sexes on an associative learning task at Sierra Nevada (CA) field sites. Across both species, we found that males and females did not differ in their ability to learn, although males were slower to respond to the sucrose reward. These results offer the first evidence from natural populations that male bumblebees may be equally as able to learn associations as females, supporting findings from captive colonies of commercial bees. The observed interspecific variation in learning ability opens the door to using the Bombus system to test hypotheses about comparative cognition.

This chapter studies how social ranking in humans emerged as the result of an evolutionary process. It starts with the story of the discovery of pecking order among chickens by a Norwegian boy. Both animals and humans need a healthy balance between cooperation and competition to ensure evolutionarily efficient strategies. The biological machinery behind social ranking is discussed. There are two distinct mechanisms for navigating the social ladder: dominance and prestige. Dominance, an evolutionarily older strategy, is based on the ability to intimidate other members in the group by physical size and strength. The group members don’t accept dominance-based social rank freely, only by coercion. Members of a colony fight, and the winners of these fights will be accepted as “dominants” and the losers as “subordinates.” The naturally formed hierarchy serves as a way to prevent superfluous fighting and injuries within a colony. Prestige, as a strategy, is evolutionarily younger and is based on skills and knowledge as appraised by the community. Prestige hierarchies are maintained by the consent of the community, without pressure being applied by particular members. The mechanisms of forming and maintaining social hierarchies are described. Social structures, both hierarchies and network organizations, are reviewed. Discussion of these structures is carried over to social and political history and the tension between democracy and authoritarianism.

Learning Experiment

Cognitive abilities allow animals to navigate through complex, fluctuating environments. In the present study, we tested the performance of a captive group of eight crows, Corvus corone and 10 domestic chickens, Gallus gallus domesticus , in the cylinder task, as a test of motor inhibitory control and reversal learning as a measure of learning ability and behavioural flexibility. Four crows and nine chickens completed the cylinder task, eight crows and six chickens completed the reversal learning experiment. Crows performed better in the cylinder task compared with chickens. In the reversal learning experiment, species did not significantly differ in the number of trials until the learning criterion was reached. The performance in the reversal learning experiment did not correlate with performance in the cylinder task in chickens. Our results suggest crows to possess better motor inhibitory control compared with chickens. By contrast, learning performance in a reversal learning task did not differ between the species, indicating similar levels of behavioural flexibility. Interestingly, we describe notable individual differences in performance. We stress the importance not only to compare cognitive performance between species but also between individuals of the same species when investigating the evolution of cognitive skills.

Abstract Informal social hierarchies within small human groups are argued to be based on prestige, dominance, or a combination of the two (Henrich & Gil-White, 2001). Prestige-based hierarchies entail the ordering of individuals by the admiration and respect they receive from others due to their competence within valued domains. This type of hierarchy provides benefits for subordinates such as social learning opportunities and both private and public goods. In contrast, dominance-based hierarchies entail the ordering of individuals by their capacity to win fights, and coerce or intimidate others. This type of hierarchy produces costs in subordinates due to its aggressive and intimidating nature. Given the benefits and costs associated with these types of social hierarchies for subordinates, we hypothesised that prestige and dominance cues are better recalled and transmitted than social rank cues that do not elicit high prestige or dominance associations (i.e. medium social rank cues). Assuming that for the majority of the population who are not already at the top of the social hierarchy it is more important to avoid the costs of dominance-based hierarchies than to obtain the benefits of prestige-based hierarchies, we further hypothesised that dominance cues are better transmitted than prestige cues. We conducted a recall-based transmission chain experiment with 30 chains of four generations each (N = 120). Participants read and recalled descriptions of prestigious, dominant, and medium social rank footballers, and their recall was passed to the next participant within their chain. As predicted, we found that both prestige cues and dominance cues were better transmitted than medium social rank cues. However, we did not find support for our prediction of the better transmission of dominance cues than prestige cues. We discuss whether the results might be explained by a specific social-rank content transmission bias or by a more general emotional content transmission bias.

Informal social hierarchies within small human groups are argued to be based on prestige, dominance, or a combination of these two (Henrich & Gil-White, 2001). Prestige-based hierarchies entail the ordering of individuals by the level of admiration and respect they receive from others due to their competence within valued domains. This type of hierarchy provides benefits for subordinates such as high-quality social learning opportunities and both private and public goods. In contrast, dominance-based hierarchies entail the ordering of individuals by their capacity to win fights, coerce and intimidate others. This type of hierarchy produces costs in subordinates due to its aggressive and intimidating nature. Given the benefits and costs associated with these types of social hierarchies for subordinates, we hypothesized that prestige and dominance cues are better recalled and transmitted than social rank cues that do not elicit high prestige or dominance associations (here medium social rank cues). Assuming that for the majority of the population who are not already at the top of the social hierarchy it is more important to avoid the costs of dominance-based hierarchies than to obtain the benefits of prestige-based hierarchies, we hypothesized that dominance cues are better transmitted than prestige cues. We conducted a recall-based transmission chain experiment with 30 chains of four generations each (N=120). Participants read and recalled three descriptions of prestigious, dominant and medium social rank footballers, and their recall was then passed to the next participant within their chain. As predicted, we found that both prestige cues and dominance cues were better transmitted than medium social rank cues. However, we did not find support for our prediction of the better transmission of dominance cues over prestige cues. We discuss whether the results might be explain by a specific social-rank content transmission bias or by a more general emotional content transmission bias.

The Relationship

Background. The social rank theory of psychopathology suggests that with the evolution of social hierarchies various psychobiological mechanisms became attuned to the success or failure in conflict situations. Specifically, subordinates and those who have lost status are at greater risk of pathology than winners and those of higher status. In this theory concepts of defeat and entrapment are seen to be of special relevance to the study of depression. We outline the role of defeat and entrapment within the social rank theory of depression.Methods. New self-report measures of entrapment and defeat were developed and used to test predictions of the social rank theory of depression. Both a sample of students and depressed patients were assessed with these new scales and other social rank measures (e.g. social comparison and submissive behaviour).Results. The entrapment and defeat measures were found to have good psychometric properties and significantly correlated with depression. They were also strongly associated with other rank variables. Defeat maintained a strong association with depression even after controlling for hopelessness (r=0·62), whereas the relationship between hopelessness and depression was substantially reduced when controlling for defeat. Entrapment and defeat added substantially to the explained variance of depression after controlling for the other social rank variables.Conclusions. Defeat and entrapment appear to be promising variables for the study of depression. These variables may also help to develop linkages between human and animal models of psychopathology.

Dominance and prestige represent evolved strategies used to navigate social hierarchies. Dominance is a strategy through which people gain and maintain social rank by using coercion, intimidation, and power. Prestige is a strategy through which people gain and maintain social rank by displaying valued knowledge and skills and earning respect. The current article synthesizes recent lines of research documenting differences between dominance- versus prestige-oriented individuals, including personality traits and emotions, strategic behaviors deployed in social interactions, leadership strategies, and physiological correlates of both behaviors. The article also reviews effects that dominance versus prestige have on the functioning and well-being of social groups. The article also presents opportunities for future research and discusses links between dominance and prestige and the social psychological literature on power and status.

The One

In the European society of the Ancien Régime lifestyle was an effective pointer to the social class to which a family and its members belonged. Social hierarchies were reflected in patterns of consumption: the upper classes had a definite need for ostentation, since lavish spending made their position at the top of the social scale manifest. Clothing had a decisive function in this connection: clothes were undoubtedly the most visible marks of high living, embodying a whole series of status signals – the quality of the cloth, the richness of the accessories, the colours – clearly identifying the social rank of the wearer. Yet a number of recent studies on pre-industrial consumerism have shown that in England – chiefly, but not alone among European societies – a taste and feeling for consumer goods caught on among other social classes besides the upper. It follows that the correspondence between clothing – or more broadly, a consumer pattern – on the one hand, and rank, on the other, is not something one can apply mechanically. The web of connections between dress and social hierarchy in early modern Europe was highly complex and varied, as the ensuing remarks briefly suggest.

Popular Speech

In recent years historians of Europe and North America have discovered the importance of the spoken word in past times and have explored the ways in which language reflects particular social contexts. Retrieving fragments of popular speech from police reports, court records, and other sources, these scholars have sketched colorful vignettes which reenact such mundane activities of daily life as a game of cards or an argument over a stray calf. Their work has shown that seemingly trivial face-to-face encounters offer valuable clues for understanding social hierarchies and community values of a given time and place. Abstract relationships of class, gender, and social rank take concrete form in the routine conversations of men and women in streets, taverns, and markets, as “ordinary” people tell us about the societies in which they lived—sometimes explicitly, sometimes implicitly, but always in their own words. The historian of popular speech moreover recognizes that the social order, far from being static, remains subject to continuous modification not only by the powerful but also by those in subordinate positions, whose words and gestures may either reinforce or undermine accepted standards of behavior and social precedence.

Language is acquired in part through statistical learning abilities that encode environmental regularities. Language development is also heavily influenced by social environmental factors such as socioeconomic status. However, it is unknown to what extent statistical learning interacts with SES to affect language outcomes. We measured event-related potentials in 26 children aged 8–12 while they performed a visual statistical learning task. Regression analyses indicated that children’s learning performance moderated the relationship between socioeconomic status and both syntactic and vocabulary language comprehension scores. For children demonstrating high learning, socioeconomic status had a weaker effect on language compared to children showing low learning. These results suggest that high statistical learning ability can provide a buffer against the disadvantages associated with being raised in a lower socioeconomic status household.
