Instrumental Conditioning INSTRUMENTAL CONDITIONING: A specific behaviour leads to a specific consequence The learning of a contingency between behaviour and consequence PRIMARY REINFORCER - Biological - food, pleasure, sleep SECONDARY REINFORCER - Has no biological value - stickers, tokens, money, grades EDWARD L. THORNDIKE Began his experiment by putting cats in a puzzle box. The puzzle box could be opened if cat performed a specific behaviour such as pulling on a rope. Outside the box was food for motivation. Recorded escape time and the cats engaged in random behaviour. As the cats struggle, the cats would pull on the rope by accident. Dramatic step down for later trials. The frequency of the random behaviour gradually decreased over time. Suggested that animals follow a specific stimulus process with little credit for consciousness. There was never a “Aha moment” like humans. STAMPED IN Rope pulling lead to food STAMPED OUT Random behaviours like turning in circles LAW OF EFFECT Behaviour that produce positive consequences will be stamped in and performed more frequently. Behaviour with negative consequences are stamped out and performed less frequently. TYPES OF INSTRUMENTAL CONDITIONING

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    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.
