Watson & Rayner (1920) - "Little Albert"

John B. Watson and Rosalie Rayner are going to introduce classical conditioning to the Americans with a famous study involving a 11-month old baby who will be called "Little Albert."  The study of that article is worthwhile for several reasons.  One reason is that it will give you the opportunity to apply your knowledge of the basic procedures to an applied situation.  Below are a series of questions.  If the answers come easily then you know that you understand the basics.

1.  What is the Unconditioned Reflex?  Why does it get that label?  What is the UCS?  What is the UCR?  Why do they get that label?

2.  What is the effect we are looking for to indicate this is a case of classical conditioning?

3.  What is the Conditioned Reflex?  Why does it get that label?  What is the CS and CR?  Why do they get that label?

4.  What type of conditioning procedure is being used?  How do you know?

5.  Is the conditioning effect tied to only the original CS or does it spread to other stimuli?  How effective is the spread?  What does that mean? (Pay attention to the blocks.  What is going on there?)

6.  Once the conditioned reflex is produced, then is it a constant effect or does it change in strength?  What does that mean?

7.  Watson and Rayner change location to be able to film Little Albert.  What happened?  What does that tell us about the classical conditioning effect?

8.  Watson and Rayner tested Albert about 1 month later.  What happened?  What does that tell us about the conditioning effect?

9.  If we tested Albert when he was 10 years old then what would be your prediction about the effect?  Why?
