Lecture 3: Developmental Psychology Background: The Industrial Revolution During the industrial revolution, children were seen as mini adults (the sapling theory). Sigmund Freud developed a different way of thinking about development (stage theory), where children go through different age ranges, and at every age they are a different creature (the caterpillar theory; children look quite different from us, and have the ability to develop into adults). Jean Piaget examined children and found they were very different from adults. Prior to his research, children were employed at ages as young as six without a second thought. Most children didn’t receive education outside of home and the workplace; only the most privileged received external education. Alfred Baney suggested the concept of universal education, rather than only certain children being educated. Following this, other laws such as the child labour laws were put in place. Affective Development: Attachment Theory Harry Harlow: A behaviourist during the 1950s; used chimpanzees to further his research rather than the common observation animal in a lab (rats). - When breeding chimps for more research, they would separate the baby from the mother at birth because they had found that captive mothers didn’t make good mothers. When they were kept in their own cages, they would have cloth diapers left on the bottom of the cage for them to do their business on. Every time the lab asst.’s had to clean the cages, the babies would cling to the diapers for dear life and would cry for it until it was replaced. Harlow noted that the babies were falling in love with the diapers in place of their mothers (something to cuddle, warmer than the rest of the cage). Theories about mothers: 1. Freud; believed that babies were highly sexual beings in the area of the mouth. Because breast feeding is common, it was determined that the child felt strongly for their mothers for fulfilling this sexual need. 2. Behavioralist view; basic needs were met, and the baby would associate with the person who brought them the things they needed (usually the mother). Both theories have attachment as a secondary. A theory was developed concerning evolutionary emotion, questioning if we came into this world willing and ready to fall in love with something in our environment. This loving bond would highly increase the survival of the child, as they would have the bigger entity to defend, feed, and care for themselves. Harlow developed a concept about attachment being a primary rather than a secondary process to prove his theory about the chimp and the diaper.
