Two researchers from the University of Hong Kong suggest that toymakers and parents avoid gender-labelling toys, remove colour divides, and manufacture toys for both boys and girls in a wide range of colours. Sui Ping Yeung and Wang Ivy Wong’s study is published in Springer’s journal Sex Roles, and shows how easily preschoolers’ ideas about what is appropriate for their gender is manipulated. Their study is also the first to show that a boy’s preference for blue and a girl’s liking of pink is not just a Western construct, but is also a phenomenon in urban Asian societies.
