title: Birth order and locus of control revisited: sex of siblings as a moderating factor.
abstract: Rotter's Locus of Control scale was administered to 64 first-born and 157 other undergraduate students, and data on the sex of participants' siblings were also obtained. The sex of participants' siblings was significantly correlated with locus of control among first-borns but not among other participants.
