When is it appropriate to ask a question? The role of age, social context, and personality

How do children decide when it is appropriate to ask a question? In Study 1 (preregistered), 50 4- and 5-year-olds, 50 7- and 8-year-olds, and 100 adults watched vignettes featuring a child who had a question, and participants indicated whether they thought the child should ask the question “right now.” Both adults and children endorsed more question-asking to a well-known informant than to an acquaintance and to someone doing nothing than to someone busy working or busy socializing. However, younger children endorsed asking questions to someone who was busy more often than older children and adults. In addition, Big Five personality traits predicted endorsement of question-asking. In Study 2 (preregistered, N = 500), mothers’ self-reports showed that children's actual question-asking varied with age, informant activity, and informant familiarity in ways that paralleled the results of Study 1. In Study 3 (N = 100), we examined mothers’ responses to their children's question-asking and found that mothers’ responses to their children's question-asking varied based on the mother's activity. In addition, mothers high in authoritarianism were less likely to answer their children's questions when they were busy than mothers low in authoritarianism. In sum, across three studies, we found evidence that the age-related decline in children's question-asking to their parents reflects a change in children's reasoning about when it is appropriate to ask a question.
