Abstract
Rats were trained in a discriminated lever press avoidance situation in which three intensities of white noise were warning signals and a fourth intensity, the highest, was not followed by shock. After initial performance to this highest intensity stimulus decreased, the typical stimulus intensity dynamism (SID) gradient over the three warning signal intensities did not obtain. When the highest intensity stimulus was then made a warning signal, followed by shock, the usual SID gradient reappeared.
