Answer:
Watson and rayner taught "little albert" to fear white rats by repeatedly pairing a loud noise with the presentation of a white rat.
Step-by-step explanation:
In this classical experiment, Watson and Rayner used the principle of neutral stimulus to understand and analyze the behavior. Associating the fear of a stimulus, the pair of scientists proved that the human mind works through the association with something that is traumatic and responds properly. In this case, a loud noise created the trauma when associated with a white rat. This experiment is part of the Behaviorism theory, which explains that human being expresses their emotions and social skills through a behavior pre-established for someone or something, based in a stimulus.
