Abstract
Rats were studied in a situation employing a tone CS and shock US; rotation of a wheel before the onset of US terminated CS and avoided shock, whereas rotation during US terminated shock and tone simultaneously. The avoidance response was learned to a high level of the 1st 2 days, but declined to a very low frequency by the 7th day. An explanation in terms of general debility or response decrement is ruled out, since bar-pressing rates for food reward did not show such a decrease. From Psyc Abstracts 36:01:1EK90C.
