Ruffman, Ted; Perner, Josef; Naito, Mika; Parkin, Lindsay; Clements, Wendy A.
Developmental Psychology, v34 n1 p161-74 Jan 1998
Four experiments and an analysis of pooled data from English and Japanese children show a linear increase in understanding false beliefs with number of older siblings; no such effect for children younger than 38 months; no helpful effect of younger siblings at any age; no effect of siblings' gender; and no helpful effect of siblings on a source task.
