Young children are often prone to an ‘empirical’ bias when asked to reason from premises that do not conform to their everyday knowledge. Experiment 1 identified three cues that help 4- and 5-year-olds to suppress this bias: when the premises are presented with a make-believe intonation; when they are presented in the context of a remote setting, such as another planet; and when they are accompanied by visual imagery. The facilitatory effect of all three cues suggests that children will accept premises that violate their empirical knowledge as a basis for reasoning so long as they are presented in a make-believe mode rather than a literal mode. Experiment 2 showed that this facilitatory effect on logical reasoning occurs for 4- and 6-year-old children alike. The pattern of results is linked to other developments in young children's imaginative abilities.
