Marr Psychology 3030/6016 11/16/06 SAMPLE TEST ITEMS 1. In the steady state, fixed-interval (FI t ) schedules engender highly variable numbers of responses per interval. For example, in one study (Zeiler, 1979) a pigeon pecking a key under an FI 120-min schedule for food emitted an average of 1800 responses per interval over many intervals; the number of responses from interval to interval ranged from 30 to 5500 (SD = 1280). Considering what you know about the dynamics operating in contingencies, why do you think responding is so variable under FI schedules (i.e., provide a reasonable account). How might you experimentally compare performance under the above FI 120-min schedule with: a) a variable-ratio schedule and b) a fixed- ratio schedule ? What are you likely to find? Why? Be specific. 2. Carefully distinguish between Baum’s designations of “O-Rules” (functional relations) and “E-Rules” (feedback functions) and give specific examples. Why can’t E- rules simply be derived from O-rules, or vice-versa? How might the concept of a

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
