This includes putting the subject in different situations and adding or taking away reinforcers and/or aversive conditions What is social validity? Why do we care about it? The goals, procedures, and results of an intervention are socially acceptable to the client, the behavior analyst, and society. Because if it is not accepted by the client, analyst, or society, then it is a failure What is interobserver agreement? How do we obtain it? Why do we care about it?

    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.
