Two studies examined how children between ages 4 and 6 use body shape (i.e., the waist-to-hip-ratio [WHR]) for sex categorization.

In Experiments 1 and 2, 6- and 10-year-old children learned to classify exemplars of a novel category and then used the same exemplars in an inferential prediction task. In a subsequent classification…
