Abstract
Two experiments examined infants’ expectations about how an experimenter should distribute
resources and rewards to others. In Experiment 1, 19-month-olds expected an experimenter to
divide two items equally, as opposed to unequally, between two individuals. Infants held no
particular expectation when the individuals were replaced with inert objects, or when the
experimenter simply removed covers in front of the individuals to reveal the items (instead of
distributing them). In Experiment 2, 21-month-olds expected an experimenter to give a reward to
each of two individuals when both had worked to complete an assigned chore, but not when one
of the individuals had done all the work while the other played. Infants held this expectation only
when the experimenter could determine through visual inspection who had worked and who had not. Together, these results provide converging evidence that infants in the second year of life
already possess context sensitive-expectations relevant to fairness.
