Psychology 152 – Class Notes – 11/18/09 If you present the conditioned stimulus without pairing with the UCS (unconditioned stimuli) Events that function as conditioned stimuli (CS) are NOT permanent events can change its function both ways. The effects of a drug are not completely in a drug, but actually in the environment. KEY : Variables in the environment can modulate (change or alter) the effects of a drug. Example: Animals learned how to die - Pavlovian conditioning Psychofosomide – decreased immune function in the animals. The researchers accidentally trained the animsals immune system to stop functioning through Pavlovian conditioning. o This was a MAJOR find accidentally found Environment is not static AT ALL Now we know why some medications don’t work at certain times o Threshold – effective dose – can vary up and down (increase/decrease) Drugs don’t just do 1 thing The effects of a drug are Conditions for respondent conditioning Take a stimulus that the subject can discriminate in the environment o We are talking about only the visible range of light. o Sensory organs that detect changes in light o These are reflexive systems – these systems work without thinking about them. Unconditioned stimulus o Paired with potential Neutral stimulus – can be anything Produces an unconditioned response The neutral stimulus then becomes a conditioned stimulus over time and takes on the properties of the unconditioned stimulus

    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.
