Ok, here is the Rescorla-Wagner homework for you to try:

You have two groups, each with the same UCS (whose lambda is set to 100).  There are three CSs:  A Light (salience of .1),
a Tone (salience of .2), and a Flash (salience of .4).  On the first 5 trials, each group has the following CSs paired with the UCS:

                                               Group 1                                                  Group 2
Trial 1:                                     Light                                                       Flash
Trial 2:                                     Light                                                       Flash
Trial 3:                                     Light & Tone                                          Flash & Tone
Trial 4:                                     Light & Tone                                          Flash & Tone
Trial 5:                                     all three                                                   all three
 

On the SIXTH trial, all 3 CSs are again paired (in both groups) with the UCS, but the UCS's intensity has been dropped from 100 to 68.1

So, fill in the table for each group (answers below).
