Claims that by nature men orient to objects and women orient to people are not new (see Maccoby & Jacklin, 1974, for a review of older claims and Browne, 2002, and Pinker, 2002, for recent statements), but Connellan et al.’s (2000) experiment seems to have given them compelling support. The experiment is unusual, however, in three respects. First, it stands alone. It is customary, in infant research, to replicate key findings and assemble multiple experiments in support of any claim. No replication of Connellan et al.’s experiment has been published, however, and no unpublished replications are mentioned in Baron-Cohen’s (2003, 2005a) discussions of their finding.
