Food or Security? Harlow’s Study on Monkeys’ Attachment

This clip features classic footage of Harlow’s surrogate mother studies. Monkeys are placed in a cage with two dolls, one made of cloth, and one made of wire. They cling to the cloth doll and gain food from the wire doll. A narrator describes the study’s findings. What was Harlow trying to show with this study? Is it as true for human newborns as it is for monkeys?

In this student project, the way Disney movies often portray gender roles is explored. Through pictures, clips, and audio tracks, the video clearly paints a portrait of old-fashioned gender roles, where women are expected to be beautiful and subservient, and men are strong and powerful. Do you agree that this is how Disney movies portray gender roles or is this video offering a skewed perspective? How do these portrayals affect children’s burgeoning notions of gender identity?
