At a Johns Hopkins campus hospital in 1920, behavioral psychologists conducted an experiment with a nine-month-old boy known as Little Albert, who was given a white rat to play with. The scientists then made loud noises behind Albert’s head while he played, conditioning in him a fear of other furry animals and objects, previously sources of joy. Albert’s mother, a wet nurse at a nearby hospital, was paid one dollar for her son’s participation.
