“…This interpretation is supported by comments made by the children as they selected additional objects (e.g., "I think I know, but let me ask just one more question, to be sure"). Although these results are surprising in light of previous research showing that children of this age tend to be overconfident (e.g., Finn & Metcalfe, 2014;Salles, Semelman, Sigman, & Calero, 2016), they are consistent with research on children's decision making, which finds that younger children tend to be more exhaustive in their search than older children (Davidson, 1991a(Davidson, , 1991b. Moreover, Legare and colleagues (2013) found that the preschoolers (4to 6-year-olds) who asked more confirmatory questions (i.e., redundant based on the information already gathered) performed better overall in a 20-questions game, suggesting that the confirmatory strategy, although inefficient, may be useful.…”
