Change Nature of Association Executing the Change Nature of Association command brings up the following dialogue box. Settings in this dialogue box determine whether Sniffy learns S–S or S–R associations during classical conditioning experiments. Chapter 7 contains a detailed discussion of the circumstances under which changes in these settings are appropriate.

By clicking on the S–S or S–R alternatives, you determine whether ■ Sniffy learns a stimulus–stimulus (S–S) or a stimulus–response (S–R) association to CSs that have been paired either with the shock US or with another CS used as a US. Click the Use Defaults command button to set the association model ■ to the program’s default values: Quick Guide to Menus and Commands xxiii S–S for CSs paired with the shock US. S–R for CSs paired with another CS used as a US.

Click the Cancel command button to dismiss the dialogue box with- ■ out making any changes in the association model. Click the OK command button to dismiss the dialogue box and put ■ the current settings into effect. Nature of Association settings cannot be changed after the program ■ has begun to run a classical conditioning experiment.

Design Operant Conditioning Experiment Selecting Design Operant Conditioning Experiment brings up the dia- logue box shown below, which is used to control operant conditioning experiments. The left-hand side of the dialogue box under Reinforcement Sched- ule determines the conditions of reinforcement. Selecting ■ Continuous causes each instance of the response selected under the Reinforcement Action pull-down menu to be reinforced.

To set up a schedule of reinforcement: ■ Select Fixed for fi xed-interval (FI) or fi xed-ratio (FR) schedules. Select Variable for variable-interval (VI) or variable-ratio (VR) schedules.

Select Responses for ratio (FR or VR) schedules. Select Seconds for interval (FI or VI) schedules. The number you type in the text box in this section determines the value of the schedule, in responses for ratio schedules or sec- onds for interval schedules. Xxiv Quick Guide to Menus and Commands Selecting ■ Extinction causes reinforcement to be turned off. None of Sniffy’s bar presses produce food pellets. Selecting Mute Pellet Dispenser eliminates the sound of the pel- let dispenser as a consequence of bar pressing. To produce standard extinction conditions, Mute Pellet Dispenser should be selected.

If Mute Pellet Dispenser is not selected, Sniffy will continue to hear the sound of the pellet dispenser whenever he presses the bar. Extinction with Mute Pellet Dispenser turned off is used to study the effect of secondary reinforcement. The selection made in the drop-down menu under ■ Reinforcement Action determines which operant response the program automati- cally reinforces.
