Predictions about the effect of interstimulus intervals (ISIs) in desensitization were made from the habituation model and tested with a series of Ss, each serving as his own control. Strong items desensitized faster with long ISIs, though weak items were not affected. No effects on long-term response decrements were found. A second experiment examined an interpretation of the stimulus-length effect in desensitization in terms of an extension of the recovery period between stimulus onsets. The results permitted rejection of the hypothesis.

Starting Point

The effects of information sequencing and variations in interstimulus interval were investigated in a metered-memory-search paradigm where S responded with a rule-defined letter belonging to a memory set. If information concerning the starting point of the search was presented before the defining rule, the over-all latency was shorter than if the reverse was the case, supporting the notion that isolation of the starting position is an integral component of the metered-memory-search task. Increasing the interstimulus interval between information about the starting position and rule-defining transformation resulted over-all in a longer latency but had no effect on rate of search.
