Document Summary

According to pavlov, the cs does not elicit the conditioned response initially but comes to do so as a result of becoming associated with the us. By contrast, the us is effective in eliciting the target response from the outset (without training/conditioning). Therefore, identifying potential css and uss requires comparing the responses elicited by each stimulus. In studies of habituation, we can see that the behavioural impact of a stimulus depends on its novelty. Both phenomena serve to limit processing and attention to stimuli that are presented without a us and are therefore inconsequential. Us-preexposure effect: interference with conditioning produced by repeated exposures to the us before conditioning trials. More vigorous conditioned responding occurs when more intense conditioned and unconditioned stimuli are used. Stimulus intensity is one factor that contributes to what is generally called stimulus salience. stimulus salience: the significance or noticeability of a stimulus. Generally, conditioning proceeds more rapidly with more salient (i. e. noticeable) conditioned and unconditioned stimuli.
