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, he sees the McD entrance sign, the rear of the vehicle in front of him, and the cup of coffee when it is handed to him.

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.  What would make the sign a stronger or weaker CS+ for caffeine?

2. 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?

    c.  What situation would produce no contingency between the McD sign and caffeine?

    d.  What situation would produce a negative contingency between the McD sign and caffeine?

3.  Why do you keep saying that caffeine is a CS+?  I read on the internet that it is not good for your health.
