1. Should there be any problems the staff at MED Associates Inc is available to answer any questions that may arise Please e mail us at support med associates com with a detailed description of the problem or desired goals so that concise and detailed information may be provided The Triadic Learned Helplessness procedures are designed to be as easy to use as possible MED Associates Inc understands that researchers do not have the time to devote to programming and hardware design and for that reason we have undertaken that burden for you We sincerely hope that you are satisfied with the products and services we provide and look forward to meeting your future experimental needs as your research program evolves MED ASSOCIATES INC TRIADIC LEARNED HELPLESSNESS Overview of the Procedures The Triadic Learned Helplessness programs are designed to run three animals at the same time Subjects in the Escape condition learn to turn the response wheel to terminate the aversive stimulus for themselves and a Yoked partner The Control subject is not stimulated Triadic mpc When the program loads the left position is set to Escape the center to Control and the Right to Yoke If the system has aversive stimulators on all three positions the code may be modified to randomly select which positions left center or right are the Escape Yoke and Control Figure 1 1 Triadic System Positions Escape Control Table 1 12.
