Evolutionary Transitions in Individuality have been responsible for the major transitions in levels of selection and individuality in natural history, such as the origins of prokaryotic and eukaryotic cells, multicellular organisms, and eusocial insects. The integrated hierarchical organization of life thereby emerged as groups of individuals repeatedly evolved into new and more complex kinds of individuals. The Social Protocell Hypothesis proposes that the integrated hierarchical organization of human culture can also be understood as the outcome of an ETI—one that produced (...) a “cultural organism” from a substrate of socially learned traditions that were contained in growing and dividing social communities. The SPH predicts that a threshold degree of evolutionary individuality would have been achieved by 2.0–2.5 Mya, followed by an increasing degree of evolutionary individuality as the ETI unfolded. We here assess the SPH by applying a battery of criteria—developed to assess evolutionary individuality in biological units—to cultural units across the evolutionary history of Homo. We find an increasing agreement with these criteria, which buttresses the claim that an ETI occurred in the cultural realm. (shrink)

Philosophers and Cognitive Scientists have become accustomed to distinguishing the first person perspective from the third person perspective on reality or experience. This is sometimes meant to mark the distinction between the “objective” or “intersubjective” attitude towards things and the “subjective” or “personal” attitude. Sometimes, it is meant to mark the distinction between knowledge and mere opinion. Sometimes it is meant to mark the distinction between an essentially private and privileged access to an inner world and a merely inferential or (...) speculative access to that world. No doubt there are other uses as well. But I don't care about this dichotomy here, or indeed any of these putative distinctions it is alleged to mark. Instead, I want to call attention to the central role of the less often acknowledged grammatical and phenomenological category, that of the second person. This category is essential not only for understanding the development of self-understanding, but also for the development of the moral sense that allows us to participate in the societies that constitute us as persons. The task of moral education is the cultivation of care for second persons. But we do so by extending not self-regard (for that is inextensible—others are not oneself), but by extending the spontaneous caring response we have for those with whom we immediately interact—second persons. Our moral lives, I will argue, like our cognitive lives, cannot be understood without understanding the special nature of second person relationships. In short, I will argue that the second person perspective is in fact essential to the constitution of human subjectivity, and that it permeates all forms of interpersonal consciousness and even self-consciousness.

According to many scholars, prosociality, in particular altruism and empathic concern, is considered an important motivational factor both in adulthood and in the development of morality. So far, a large number of studies have addressed the development of children’s first-party prosociality and their third-party understanding of moral norms separately. In particular, there is much evidence that during the second year of life, young children develop empathic concern and sympathy for others in need in prosocial situations. Moreover, recent findings suggest that (...) 18-month-old infants already show some rudimentary forms of norm understanding in at least dyadic conventional situations. This rudimentary norm understanding is interpreted as second-personal normative expectations. Finally, 3-year-old children not only have descriptive expectations about morality, but also normative ones as suggested by their enforcement of moral norms as unaffected bystanders. However, the interrelation between prosociality and morality, in particular the prosocial motivational source of the early sense of morality remains unclear. This thesis aimed to investigate the developmental origins of morality in young children. In particular, it examines the relation between the two main aspects of uniquely human cooperation – prosociality and morality – from a developmental perspective. These two aspects are of particular importance, not only because they each play a key role in maintaining the unique human capacity for large-scale cooperation but also because of their close relation to each other. The present thesis therefore focused on three guiding questions that are essential for the ontogeny of morality and its relation to young children’s prosocial motivation to understand, adhere to, and enforce moral norms: What are the developmental origins of morality? What is the underlying prosocial motivation for children's normative appreciation of morality? What is the scope of morality? Study 1 investigated the developmental origins of morality in 18-month-old infants. A novel eye-tracking paradigm was used to examine whether infants differentiate between prototypical moral and conventional violations. In a between-subjects-design, children watched the same video clip whose audio stream differed according to condition. In the first two conditions, an instructor told an observer to destroy a picture with a particular tool chosen from two available tools. In the moral violation condition, the instructor forbade the observer to destroy the picture at all. In all three conditions, the observer then grasped tool B and destroyed the picture, which led to three different situations. Infants differentiated between two types of conventional norm situations in their anticipatory looking. Moreover, they showed a larger relative increase in pupil dilation in response to a moral violation than to a conventional violation. These findings suggest that 18-month-old infants have third-party descriptive expectations about the distinction between conventional and moral violation situations. Moreover, they provide the first evidence that empathic concern may be a decisive capacity for the distinction between these two violation situations. Study set 2 looked at the underlying prosocial motivation for the appreciation of morality as a normative notion in 3-year-old children. In three experiments, children were given a third-party fairness task and two different prosocial tasks. To investigate whether the children have a proper norm understanding of fairness by looking not only at norm adherence, but also at norm enforcement, a spontaneous protest paradigm was used. In Experiment 1, children protested and corrected unequal allocations, suggesting a normative understanding of third-party fairness. Experiment 2 assessed whether children’s normative expectations about fairness have a moral dimension. To do so, children observed a distributor who followed or violated an authority’s command to allocate resources unequally. Again, despite the authority’s dictate to act unequally, children protested more against unequal versus equal allocations. In Experiment 3, results show that children enforced fairness norms by altruistic punishment in the sense of restorative justice. While in Experiment 1 and 2 I found a positive relation of protest behavior and emotional sharing, in Experiment 3 children’s altruistic punishment was associated with their own costly sharing behavior. Finally, in Study 3, I explored the scope of morality in 5-to 6-year-old children in a typical intergroup context. Here, I investigated whether decategorization – a candidate mechanism to overcome in-group bias by emphasizing the individual person – would lead preschoolers to treat in-group and out-group members equally when sharing resources in a dictator game. I found that preschoolers shared more resources with an in-group than with an out-group recipient when social category membership was emphasized. When individuating information was emphasized, however, children shared the same with in-group and out-group individuals. Taken together, the empirical studies of this dissertation provide a novel overview of the prosocial roots of children's developing morality. In particular, the present findings suggest that the ability to feel sympathy may be critical for the development of the moral-conventional distinction and that 18-month-old infants, at minimum, have third-party descriptive expectations about that distinction. The ontogeny of fairness norms can be characterized as moral in that it is associated with 3-year-old children’s developing concern for the welfare of others in different contexts. The presentation of out-group members as individuals may be a powerful tool to reduce in-group bias and to foster equal treatment of in-group and out-group members in 5- to 6-year-old preschool children.
