The effects of ITI interpolated stimuli and CS intensity on classical conditioning of the nictitating membrane response of the rabbit

The effects of white noise bursts of 5 sec duration, interpolated 30 sec into a 1 min ITI, were compared on the conditioning rates of Ss trained under high and low CS intensities. The interpolated stimulus produced a significant decrement in conditioning at the high but not at the low intensity value. It is suggested that higher CS intensities may shorten the time available for ITI consolidation.
