Contiguity vs. Contingency
"Is the McD sign a good CS+ for caffeine?"

Joe has a daily ritual.  He wakes up, yawns and scratches, and puts on yesterday's clothes.  He gets into his car and drives to McDonalds and buys a cup of coffee to prepare himself for the dreaded Psychology class.

When he goes through the drive-through line, First, he sees the McD entrance sign; Second, the rear logo of the vehicle in front of him (must all cars be a Subaru in Boone?); Third, he sees the cup of coffee when it is handed to him; Fourth, there is the sweet taste of coffee in his mouth.

We will assume the caffeine in the coffee is a UCS and the UCR is an increase in heart rate.  The question is whether the McD sign is a good CS+.

1. Do a contiguity analysis.  According to contiguity analysis, what is the best CS+?

2. Do a contiguity analysis.  What would make the sign a stronger or weaker CS+ for caffeine?

3. Do a contingency analysis:

    a.  What is the essential characteristic of doing a contingency analysis of a potential CS?

    b.  What situation would produce a positive contingency between the McD sign and caffeine?  Do we call it a CS+ or CS-?

    c.  What situation would produce no contingency between the McD sign and caffeine?  Do we call it a CS+ or a CS-?

    d.  What situation would produce a negative contingency between the McD sign and caffeine?  Do we call it a CS+ or CS-?

4.  Why would you say that the McD sign could be a CS+?  I read on the internet that caffeine is not good for your health and could be addictive.
