Abstract

Chimpanzees provide help to unrelated individuals in a broad range of situations. The pattern of helping within pairs suggests that contingent reciprocity may have been an important mechanism in the evolution of altruism in chimpanzees. However, correlational analyses of the cumulative pattern of interactions over time do not demonstrate that helping is contingent upon previous acts of altruism, as required by the theory of reciprocal altruism. Experimental studies provide a controlled approach to examine the importance of contingency in helping interactions. In this study, we evaluated whether chimpanzees would be more likely to provide food to a social partner from their home group if their partner had previously provided food for them. The chimpanzees manipulated a barpull apparatus in which actors could deliver rewards either to themselves and their partners or only to themselves. Our findings indicate that the chimpanzees' responses were not consistently influenced by the behavior of their partners in previous rounds. Only one of the 11 dyads that we tested demonstrated positive reciprocity. We conclude that contingent reciprocity does not spontaneously arise in experimental settings, despite the fact that patterns of behavior in the field indicate that individuals cooperate preferentially with reciprocating partners.

  • Psychological factors implicated in cultural evolutionary processes include attentional resources, social learning biases and predispositions towards learning from other conspecifics that appear at least somewhat unique to humans.

    “Psychological factors (and the genetic predispositions that may underpin them) that are implicated in cultural evolutionary processes include the attentional resources, social learning biases and predispositions towards learning from other conspecifics that appear to be at least somewhat unique to humans”

    From Cultural Evolution of Religion, Spirituality and Ritual: Impacts On Human Cooperation (2024) · cites this paper as Brosnan et al. 2009

    The Introduction discusses chimpanzees’ cognitive requirements for contingent reciprocity, and the Discussion addresses their behavior in an experimental task; neither addresses psychological factors in cultural evolution. Searches for attentional resources, social learning biases, and human-unique predispositions to learn from conspecifics found no passage supporting the attributed claim. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
