Children's social preferences are influenced by the relative status of other individuals, but also by their social identity and the degree to which those individuals are like them. Previous studies have investigated these aspects separately and showed that in some circumstances children prefer high-status individuals and own-gender individuals. Gender is a particularly interesting case to study because it is a strong dimension of social identity, but also one of the most prevalent forms of social hierarchy, with males conceptualised as superior to females, by adults and children alike.

In adults, seeing individual faces is sufficient to trigger dominance evaluations, even when conflict is absent. From early on, infants represent dyadic dominance relations and they can infer conflict outcomes based on a variety of cues. To date, it is unclear if toddlers also make automatic dominance trait evaluations of individual faces.

Article Synopsis
  • This study explored how social hierarchies are structured, hypothesizing that they would take on a pyramidal shape to better manage conflicts over resources.
  • Analysis showed that this pyramidal structure is common across 114 species, suggesting it's a widespread phenomenon not significantly affected by group size or evolutionary background.
  • Experiments revealed that both adults and infants make consistent inferences about social dominance based on this pyramidal structure, while they struggle to do the same with other shapes like trees, indicating an innate ability to understand hierarchies from an early age.

Visual illusions have always fascinated people but they have often been confined to the field of entertainment. Although philosophers, psychologists and neuroscientists have used them to explore the bases of human perception and to teach about vision, these attractive tools have still remained largely underexploited. The goal of the present paper is to argue that visual illusions can also serve as a powerful medium to question our relation to the world and to others, as they demonstrate that we do not fully perceive reality and that each interpretation of the world may be equally sound.

Social discounting predicts that one's concern for others decreases with increasing social distance. Cultural dimensions may influence this social behavior. Here, we used a dictator game, in which the participants and real members of their social entourage profited from the partition of the endowments determined by the participant, to compare how Chinese and French university students shared endowments with people at different social distances.

  • The study aimed to assess how nonviolent communication (NVC) training affects medical students' empathy, using various implicit and explicit measurement methods.
  • 312 French medical students were divided into an intervention group (123 students who received NVC training) and a control group (189 students) to compare empathy skills before and after training.
  • Results showed a significant improvement in empathy scores for the intervention group, indicating that NVC training can enhance empathic abilities among medical students, suggesting its potential value in medical education.

Previous research on Montessori preschool education is inconsistent and prone to analytic flexibility. In this preregistered study, disadvantaged preschoolers in a French public school were randomly assigned to either conventional or Montessori classrooms, with the latter being adapted to French public education. Adaptations included fewer materials, shorter work periods, and relatively limited Montessori teacher training.

Gender studies have largely described social practices that lead to an imbalance of power between girls and boys during childhood. However, little is known about how children represent asymmetries in mixed-gender relationships. Do they expect that males are more likely to exert power on females than vice versa? And if so, does this awareness change depending on children's age, gender, or the country in which they grow up? We present herein an empirical study, recently published in Sex Roles, that addresses these issues.

Upon learning of the story of Cinderella, most people spontaneously adopt the emotional perspective of this helpless young woman rather than of her older sisters who oppress her. The present research examines whether this pattern reveals a general human tendency to empathise more with the emotions of individuals with low (versus high) power. Six experiments ( = 878) examined how power influences the focus of people's emotional attributions.

This study examines the influence of social hierarchy on the neural electrophysiological responses to faces. In contrast with earlier EEG studies that typically manipulate social rank through competitive situations, we implemented hierarchy through occupational status and thus contrasted faces associated with high- vs. low-status (e.

Hierarchy is a recurrent feature of social life. From an early age, children are confronted with power relationships wherein a dominant individual imposes his/her will to a subordinate individual. Recent research has shown that young children develop sophisticated abilities in understanding power.

In the course of evolution, social dominance has been a strong force shaping the organization of social systems in many species. Individuals with a better ability to represent social dominance relationships and to adapt their behavior accordingly usually achieve better access to resources, hence providing benefits in terms of reproduction, health, and wellbeing. Understanding how and to what extent our brains are affected by social dominance requires interdisciplinary efforts.

Scalar implicatures, the phenomena where a sentence like "The pianist played Mozart sonatas" is interpreted, as "The pianist did play Mozart sonatas" have been given two different analyses. Neo-Griceans (NG) claim that this interpretation is based on lexical scales (e.g.

Two experiments with preschoolers (36 to 78 months) and 8-year-old children (Experiment 1, N = 173; Experiment 2, N = 132) investigated the development of children's resource distribution in dominance contexts. On the basis of the distributive justice literature, 2 opposite predictions were tested. Children could match resource allocation with the unequal social setting they observe and thus favor a dominant individual over a subordinate 1.

Two important parenting strategies are to impose one's power and to use reasoning. The effect of these strategies on children's evaluation of testimony has received very little attention. Using the epistemic vigilance framework, we predict that when the reasoning cue is strong enough it should overcome the power cue.

Recent research has shown that young children rely on social cues to evaluate testimony. For instance, they prefer to endorse testimony provided by a consensual group than by a single dissenter. Given that dominance is pervasive in children's social environment, it can be hypothesized that children also use dominance relations in their selection of testimony.

There is now general agreement about the optionality of scalar implicatures: the pragmatic interpretation will be accessed depending on the context relative to which the utterance is interpreted. The question, then, is what makes a context upper- (vs. lower-) bounding.

Recent research in moral psychology have suggested that children make judgments about distributive justice early on in development, and in particular they appear to be able to use merit when distributing the benefits of a collective action. This prediction has recently been validated in various western cultures but it is unknown whether it also applies to more collectivistic cultures, in which the group might be favoured over the individual, and need over merit. Here, we investigate merit-based distributions among 81 children belonging to two Asian societies, China and Japan (mean age = 5.

Neuroimaging studies have contributed to a major advance in understanding the neural and cognitive mechanisms underpinning deductive reasoning. However, the dynamics of cognitive events associated with inference making have been largely neglected. Using electroencephalography, the present study aims at describing the rapid sequence of processes involved in performing transitive inference (A B; B C therefore "A C"; with AB meaning "A is to the left of B").

Recognition of social hierarchy is a key feature that helps us navigate through our complex social environment. Neuroimaging studies have identified brain structures involved in the processing of hierarchical stimuli but the precise temporal dynamics of brain activity associated with such processing remains largely unknown. Here, we used electroencephalography to examine the effect of social hierarchy on neural responses elicited by faces.

Although the Modus Ponens inference is one of the most basic logical rules, decades of conditional reasoning research show that it is often rejected when people consider stored background knowledge about potential disabling conditions. In the present study we used EEG to identify neural markers of this process. We presented participants with many and few disabler conditionals for which retrieval of disabling conditions was likely or unlikely.

The combined knowledge of word meanings and grammatical rules does not allow a listener to grasp the intended meaning of a speaker's utterance. Pragmatic inferences on the part of the listener are also required. The present work focuses on the processing of ironic utterances (imagine a slow day being described as "really productive") because these clearly require the listener to go beyond the linguistic code.
