    Children's Intrinsic Motivation to Provide Help Themselves After Accidentally Harming Others.
    (Child Dev, 2016-11-01) Hepach, Robert; Vaish, Amrisha; Tomasello, Michael
    Little is known about the flexibility of children's prosocial motivation. Here, 2- and 3-year-old children's (n = 128) internal arousal, as measured via changes in pupil dilation, was increased after they accidentally harmed a victim but were unable to repair the harm. If they were able to repair (or if they themselves did not cause the harm and the help was provided by someone else) their arousal subsided. This suggests that children are especially motivated to help those whom they have harmed, perhaps out of a sense of guilt and a desire to reconcile with them. Young children care not only about the well-being of others but also about the relationship they have with those who depend on their help.

    The fulfillment of others' needs elevates children's body posture.
    (Dev Psychol, 2017-01) Hepach, Robert; Vaish, Amrisha; Tomasello, Michael
    Much is known about young children's helping behavior, but little is known about the underlying motivations and emotions involved. In 2 studies we found that 2-year-old children showed positive emotions of similar magnitude-as measured by changes in their postural elevation using depth sensor imaging technology-after they achieved a goal for themselves and after they helped another person achieve her goal. Conversely, children's posture decreased in elevation when their actions did not result in a positive outcome. These results suggest that for young children, working for themselves and helping others are similarly rewarding. (PsycINFO Database Record

    The relation between young children's physiological arousal and their motivation to help others.
    (Neuropsychologia, 2017-10-10) Hepach, Robert; Vaish, Amrisha; Müller, Katharina; Tomasello, Michael
    Children are motivated to help others from an early age. However, little is known about the internal biological mechanisms underlying their motivation to help. Here, we compiled data from five separate studies in which children, ranging in age from 18 months to 5.5 years, witnessed an adult needing help. In all studies, we assessed both (1) children's internal physiological arousal via changes in their pupil dilation, and (2) the latency and likelihood of them providing help. The results showed that the greater the baseline-corrected change in children's internal arousal in response to witnessing the need situation, the faster and more likely children were to help the adult. This was not the case for the baseline measure of children's tonic arousal state. Together, these results suggest that children's propensity to help is systematically related to their physiological arousal after they witness others needing help. This sheds new light on the biological mechanisms underlying not only young children's social perception but also their prosocial motivation more generally.

    The specificity of reciprocity: Young children reciprocate more generously to those who intentionally benefit them
    (Journal of Experimental Child Psychology, 2018-03-01) Vaish, Amrisha; Hepach, Robert; Tomasello, Michael
    © 2017 Elsevier Inc. Young children engage in direct reciprocity, but the mechanisms underlying such reciprocity remain unclear. In particular, prior work leaves unclear whether children's reciprocity is simply a response to receiving benefits (regardless of whether the benefits were intended) or driven by a mechanism of rewarding or preferring all benefactors (regardless of whom they benefited). Alternatively, perhaps children engage in genuine reciprocity such that they are particularly prosocial toward benefactors who intentionally provided them with benefits. Our findings support this third, richer possibility; the 3-year-olds who received benefits through the good intentions of a benefactor were subsequently more generous toward the benefactor than children who either (a) received the same benefits from the benefactor unintentionally or (b) observed the benefactor bestow the same benefits on another individual. Thus, young children are especially motivated to benefit those who have demonstrated goodwill toward them, suggesting, as one possible mechanism, an early sense of gratitude.

    Toddlers Help a Peer.
    (Child Dev, 2016-12-07) Hepach, Robert; Kante, Nadine; Tomasello, Michael
    Toddlers are remarkably prosocial toward adults, yet little is known about their helping behavior toward peers. In the present study with 18- and 30-month-old toddlers (n = 192, 48 dyads per age group), one child needed help reaching an object to continue a task that was engaging for both children. The object was within reach of the second child who helped significantly more often compared to a no-need control condition. The helper also fulfilled the peer's need when the task was engaging only for the child needing help. These findings suggest that toddlers' skills and motivations of helping do not depend on having a competent and helpful recipient, such as an adult, but rather they are much more flexible and general.

    Young Children Want to See Others Get the Help They Need
    (Child Development, 2016-11-01) Hepach, Robert; Vaish, Amrisha; Grossmann, Tobias; Tomasello, Michael
    © 2016 The Authors. Child Development © 2016 Society for Research in Child Development, Inc.Children's instrumental helping has sometimes been interpreted as a desire to complete action sequences or to restore the physical order of things. Two-year-old children (n = 51) selectively retrieved for an adult the object he needed rather than one he did not (but which equally served to restore the previous order of things), and those with greater internal arousal (i.e., pupil dilation) were faster to help. In a second experiment (n = 64), children's arousal increased when they witnessed an adult respond inappropriately to another adult's need. This was not the case in a nonsocial control condition. These findings suggest that children's helping is not aimed at restoring the order of things but rather at seeing another person's need fulfilled.
