This experiment became one of the biggest solved mysteries by John B. Watson, and a graduate by the name of Rosalie Rayner. The subject name was Douglas Merritte, a nine-month-old toddler, and the son of a wet-nurse by the name of Arvilla Merritte. She let them experiment on the child, and for letting her son be in the experiment, she received a dollar. The child nicknamed “AlbertB” for the experiment, was first exposed to a couple of items a rat, a dog, a monkey, a mask, and cotton. The now 11-month-old child showed no emotion to these animals or the items, he showed no reaction, but with the small white rat, he seemed to like it. He has presented these items again but with a certain unlikable twist.
