Final answer:
The Little Albert experiment by Watson and Rayner demonstrated classical conditioning of fear in a baby, with the fate and identity of Little Albert remaining unknown.
Step-by-step explanation:
The Little Albert experiment was a famous psychology study on the conditioning of human emotion conducted by John B. Watson and Rosalie Rayner in 1920. The subject was a baby, Little Albert, who was exposed to various neutral stimuli such as a white rat, which he initially showed no fear towards. The experimenters then associated the white rat with a startling loud noise, causing Little Albert to eventually fear the rat without the noise.
This case demonstrated classical conditioning, where the Unconditioned Stimulus (UCS) was the loud noise, the Conditioned Stimulus (CS) became the white rat, the Unconditioned Response (UCR) was fear caused by the noise, and the Conditioned Response (CR) was fear elicited by the white rat. Little Albert later generalized this fear to other furry objects, including furry coats and a Santa Claus mask. Unfortunately, the ultimate fate and identity of Little Albert remains unknown, as the experiment ended prematurely when his mother moved away, and contemporary ethical standards would disallow such an experiment.
