Describe watson&rayner procedures (10)

• Para 1

  Watson and Rayner conducted a study on a child known as Little Albert to investigate whether emotional responses could be classically conditioned. First, emotional tests were carried out to assess Albert’s baseline reactions. He was shown various stimuli, including a white rat, rabbit, dog, monkey, masks, cotton wool, and burning newspapers. These were all new to him. He showed no fear. Albert’s response to a loud noise was then tested by striking a steel bar behind his head, which caused distress.
• Para 2 - session 1 + 2

  In Session 1, when Albert was 11 months and 3 days old, the researchers paired the white rat with the loud noise. As he reached for the rat, the bar was struck behind him to induce fear. In Session 2, a week later, the conditioned response was tested. Albert was shown the rat without the noise to observe whether he had learned to fear it. Then, joint stimulation was repeated five more times (rat + noise together).
• Para 3 - session 3 and 4

  Session 3, at 11 months 15 days, tested whether the fear generalised to other objects. Albert was presented with the rat again, as well as blocks, a rabbit, a dog, cotton wool, Watson’s hair, and a fur coat. In Session 4, at 11 months 20 days, Albert’s fear was “refreshed” with further pairings and he was tested in a new environment—a large, well-lit room with people present—to assess the effect of context.
• Para 4 - session 5

  Finally, in Session 5, when Albert was 12 months 21 days, the researchers tested whether the conditioned response persisted over time. He was shown several items including the Santa Claus mask, fur coat, rat, rabbit, and dog. Throughout the study, a motion picture camera was used to record his reactions.
