In the previous lecture: We applied the Wagner-Rescorla real- time linear-operator model to the  positive correlation procedure. In today’s lecture we will continue with  this application.

To review: We used 4 computational equations to  cover all possible cases of CSA and CSX  with the US and without the US. We numbered the equations 1 through 4 to  identify which equation was used in each  period.

Unformatted text preview: 2. CS X and US: V X = X US ( US - ) 3. CS A and NO US: V A = A US ( EXT - ) 4. CS X and NO US: V X = X US ( EXT - ) To review: We established the value of all constants to be used in all calculations for all groups. Once a constant is set, it cannot be changed. Their value is arbitrary and will not influence the ordinal relationships between groups. Using the following constants: V A = 0.5 V X = 0.6 US = 0.7 US = 1.0 EXT = 0.0 Next Lecture Wagner-Rescorla Real-Time Linear-Operator Model Applying the Model CS-US Zero Correlation...
