Document Summary

How we arrange the stimuli in time do we present the neutral stimulus first or second before or after the unconditioned stimulus: delayed conditioning: present neutral stimulus first, then the unconditioned stimulus. However there is a bit of an overlap. The onset of the neutral stimulus comes before the onset of the unconditioned stimulus, and they overlap for a period of time known as the short interstimulus interval. Ex, tickling dogs lip then (before finishing) saying don"t drool : trace conditioning: onset and offset of ns precedes onset of us, and the two stimuli do not overlap. Trace interval (time between offset of ns and onset of us. Almost as effective as delayed (with short trace intervals). Duck and hit you right away, you cant predict moving as its too quick. Something that happens consistently right before hitting might get conditioned, ex, raising arm or coming closer: backward conditioning: least effective.
