Putting the Social Into Social Learning: Explaining Both Selectivity and Fidelity in Children's Copying Behavior

Harriet Over; Malinda Carpenter

Many previous accounts of imitation have pointed out that childrens copying behavior is a means by which to learn from others, while virtually ignoring the social factors which influence imitation. These accounts have thus far been unable to explain flexibility in childrens copying behavior (e.g., why children sometimes copy exactly and sometimes copy selectively). We propose that the complexity of childrens imitation can only be fully understood by considering the social context in which it is produced. Three critical factors in determining what is copied are childrens own (learning and/or social) goals in the situation, childrens identification with the model and with the social group in general, and the social pressures which children experience within the imitative situation. The specific combination of these factors which is present during the imitative interaction can lead children to produce a more or less faithful reproduction of the models act. Beyond explaining flexibility in childrens copying behavior, this approach situates the developmental study of imitation within a broader social psychological framework, linking it conceptually with closely related topics such as mimicry, conformity, normativity, and the cultural transmission of group differences.

Eighteen-Month-Old Infants Show Increased Helping Following Priming with Affiliation

Harriet Over; Malinda Carpenter

We show that the mere hint of affiliation dramatically increases prosocial behavior in infants. Eighteen-month-old infants helped a person in need more often, and more spontaneously, when primed with photographs evoking affiliation than when primed with photographs evoking individuality. This study demonstrates that social primes can have an influence on infant behavior, and so opens up a wealth of possibilities for future research. In addition, these data have wide-ranging practical implications, suggesting that subtle changes to the social environment can promote prosocial behavior in children.

Young children care more about their reputation with ingroup members and potential reciprocators

Jan M. Engelmann; Harriet Over; Esther Herrmann; Michael Tomasello

Human cooperation depends on individuals caring about their reputation, and so they sometimes attempt to manage them strategically. Here we show that even 5-year-old children strategically manage their reputation. In an experimental setting, children shared significantly more resources with an anonymous recipient when (1) the child watching them could reciprocate later, and (2) the child watching them was an ingroup rather than an outgroup member (as established by minimal group markers). This study is not only the first to show that young children selectively invest in their reputation with specific individuals, but also the first to show that we care more about our reputation with ingroup than with outgroup members.

The origins of belonging : Social motivation in infants and young children

Harriet Over

Our reliance on our group members has exerted a profound influence over our motivation: successful group functioning requires that we are motivated to interact, and engage, with those around us. In other words, we need to belong. In this article, I explore the developmental origins of our need to belong. I discuss existing evidence that, from early in development, children seek to affiliate with others and to form long-lasting bonds with their group members. Furthermore, when children are deprived of a sense of belonging, it has negative consequences for their well-being. This focus on social motivation enables us to examine why and in what circumstances children engage in particular behaviours. It thus provides an important complement to research on social cognition. In doing so, it opens up important questions for future research and provides a much-needed bridge between developmental and social psychology.

Children Draw More Affiliative Pictures Following Priming With Third-Party Ostracism

Ruiting Song; Harriet Over; Malinda Carpenter

Humans have a strong need to belong. Thus, when signs of ostracism are detected, adults often feel motivated to affiliate with others in order to reestablish their social connections. This study investigated the importance of affiliation to young children following priming with ostracism. Four- and 5-year-old children were primed with either ostracism or control videos and their understanding of, and responses to, the videos were measured. Results showed that children were able to report that there was exclusion in the ostracism videos, and that they recognized that the ostracized individual felt sad. Most interestingly, when subsequently asked to draw a picture of themselves and their friend, children primed with ostracism depicted relationships that were significantly more affiliative. Children drew themselves and their friend standing significantly closer together and adults rated their drawings as more affiliative overall. These findings introduce drawing as a useful new method for measuring social motivations and processes following an experimental manipulation, and demonstrate that affiliation is particularly important to children following even a vicarious experience of social exclusion.

Young Children Show the Bystander Effect in Helping Situations

Maria Plötner; Harriet Over; Malinda Carpenter; Michael Tomasello

Much research in social psychology has shown that otherwise helpful people often fail to help when bystanders are present. Research in developmental psychology has shown that even very young children help and that the presence of others can actually increase helping in some cases. In the current study, in contrast, 5-year-old children helped an experimenter at very high levels when they were alone but helped significantly less often in the presence of bystanders who were potentially available to help. In another condition designed to elucidate the mechanism underlying the effect, children’s helping was not reduced when bystanders were present but confined behind a barrier and thus unable to help (a condition that has not been run in previous studies with adults). Young children thus show the bystander effect, and it is due not to social referencing or shyness to act in front of others but, rather, to a sense of a diffusion of responsibility.

Young Children Are More Likely to Spontaneously Attribute Mental States to Members of Their Own Group

Niamh McLoughlin; Harriet Over

We investigated whether young children were more likely to spontaneously attribute mental states to members of their own social group than to members of an out-group. We asked 5- and 6-year-old children to describe the actions of interacting geometric shapes and manipulated whether the children believed these shapes represented their own group or another group. Children of both ages spontaneously used mental-state words more often in their description of in-group members compared with out-group members. Furthermore, 6-year-olds produced a greater diversity of mental-state terms when talking about their own social group. These effects held across two different social categories (based on gender and geographic location). This research has important implications for understanding a broad range of social phenomena, including dehumanization, intergroup bias, and theory of mind.

I won't tell : Young children show loyalty to their group by keeping group secrets

Antonia Misch; Harriet Over; Malinda Carpenter

Group loyalty is highly valued. However, little is known about young childrens loyal behavior. This study tested whether 4- and 5-year-olds (N=96) remain loyal to their group even when betraying it would be materially advantageous. Children and four puppets were allocated to novel groups. Two of these puppets (either in-group or out-group members) then told children a group secret and urged them not to disclose the secret. Another puppet (not assigned to either group) then bribed children with stickers to tell the secret. Across ages, children were significantly less likely to reveal the secret in the in-group condition than in the out-group condition. Thus, even young children are willing to pay a cost to be loyal to their group.

Young children contrast their behavior to that of out-group members

Janine Maree Oostenbroek; Harriet Over

The tendency for children to overimitate and conform to unanimous majorities is pervasive. Here we tested whether social factors are powerful enough to lead children to overcome this tendency and contrast their behavior to that of others. In one condition, children were shown a video of three out-group members performing the same action on a novel toy. In this condition, 5-year-olds, but not 4-year-olds, were significantly more likely to produce the contrasting action than the action demonstrated by the group. On the other hand, children who saw the same actions performed by neutral individuals typically matched their actions to those of the group regardless of their age. By demonstrating that 5-year-olds actively contrast their behavior to that of out-group members, these results provide an important comparison with previous research on imitation and conformity and demonstrate the profound influence that social motivations exert over childrens copying behavior.

Young children help others to achieve their social goals

Jonathan S. Beier; Harriet Over; Malinda Carpenter

From early in development, humans have strong prosocial tendencies. Much research has documented young childrens propensity to help others achieve their unfulfilled goals toward physical objects. Yet many of our most common and important goals are social--directed toward other people. Here we demonstrate that children are also inclined, and able, to help others achieve their social goals. Three-year-old children observed an experimenter trying unsuccessfully to get the attention of another individual and then helped by directing the 2nd individuals attention back to the experimenter. A control condition ensured that childrens responses were not motivated by a general desire to inform the 2nd individual about interesting events. A 2nd experiment showed that children distinguish between fulfilled and frustrated versions of this social goal and help appropriately on the basis of this distinction. Young children are therefore willing to intervene in a 3rd-party interaction to help it along. This result expands the range of situations in which young children are known to spontaneously help others into the social domain, thereby underscoring the pervasiveness of their prosocial motivations and identifying a critical area for further research.
