Document Summary
Ps261 chapter 4 notes classical conditioning: mechanisms. Looking at properties of the cs and us that influence learning to associate these two stimuli, or the cr. Pavlov said that an effective us was one that would elicit a response without any prior learning, whereas a cs would only elicit a response after being paired with a us. The fact that a comparison of responses is required means that identifying the cs and the us is relative, not absolute. The animals" initial response to the stimuli can determine how effective those stimuli will be as css and/or uss. Learning is much faster an easier if the cs and/or the us is novel. Learning is also much better if the us is novel. Intensity and salience of conditioned and unconditioned stimuli. You might see a greater cr when you use more intense and more salient cs"s and us"s. Stimulus salience = how noticeable a stimulus is.
