We also conducted individual analyses for each language for which we had instances of separate kin and non-kin interactions, fitting models with recruitment frequency as the dependent variable; interacting among kin vs non-kin as a fixed effect; and location and group as nested random effects (intercepts).

We apply a sequence-organizational method from microsociology33 that allows us to examine rapid exchanges of interactional moves and counter-moves, and that provides a structural grid for coding and comparison across languages and cultures34,35. Requesting Responsibility: The Morality of Grammar in Polish and English Family Interaction. Google Scholar. Some responses could not be coded due to partial information in the recording, for example if the recruitee was off camera at the time of responding or if the speech was inaudible.

(3) Modeling responses to recruitment as predicted by language. Kendrick, K. H. Recruitment in English: a quantitative study. Another important line of work on human prosociality and cooperation has been guided by the theoretical approach of human behavioral ecology (HBE).
