AP PSYCHOLOGY

Detailed explanation-1: -Rosalie Alberta Rayner (September 25, 1898 – June 18, 1935) was a research psychologist, and the assistant and later wife of Johns Hopkins University psychology professor John B. Watson, with whom she carried out the famous Little Albert experiment.

Detailed explanation-2: -One might consider the experiment Watson and his assistant Rosalie Rayner carried out in 1920 to be one of the most controversial in psychology. It has become immortalized in introductory psychology textbooks as the Little Albert experiment.

Detailed explanation-3: -The Little Albert Experiment demonstrated that classical conditioning-the association of a particular stimulus or behavior with an unrelated stimulus or behavior-works in human beings. In this experiment, a previously unafraid baby was conditioned to become afraid of a rat.

Detailed explanation-4: -Watson then presented the rat with a loud bang that startled Little Albert and made him cry. After the continuous association of the white rat and loud noise, Little Albert was classically conditioned to experience fear at the sight of the rat.

Detailed explanation-5: -In his most famous and controversial experiment, known today as the “Little Albert” experiment, John Watson and a graduate assistant named Rosalie Rayner conditioned a small child to fear a white rat. They accomplished this by repeatedly pairing the white rat with a loud, frightening clanging noise.
