Randomized experiment (Dahl et al., 2017) cited by the review: infants were randomly assigned to encouragement-and-praise or no-encouragement conditions before seeing an adult drop an object. The review reports that "previous encouragement and praise made infants twice as likely to hand back the dropped object."
"In one experiment, infants were randomly assigned to receive either repeated encouragement and praise for helping or no encouragement and praise (Dahl et al., 2017)."
