Document Summary
What makes effective conditioned and unconditioned stimuli. The novelty of conditioned and unconditioned stimuli. Cs and us effectiveness (as conditioning stimuli) depends on the person or animal"s prior experience with the stimulus. Interference with conditioning produced by repeated exposures to cs before conditioning trials. Interference with conditioning produced by repeated exposures to us before conditioning trials. High intensity stimuli of both types tend to enhance conditioning. The nature of the stimuli can influence the development of conditioning. Learned taste aversion demonstrates that tastes are readily associated with nausea, allowing conditioning to occur after a single exposure and with very long inter-stimulus intervals. Second order conditioning: cr transferred from one cs to another cs. Ex: metronome paired with food so that. Black square (2nd cs)--->salivation (cr)--- despite never being. Standard procedure for conditioned inhibition paired with food. Light (cs-) +bell (cs+) and no food (us) Type 1 and type 2 trials are randomly presented. Light (cs-) +bell (cs+) and no foo.
