Maintaining responding during stimulus generalization testing in extinction.
Resistance to extinction and generalization gradients were studied following training with a long-adjusting-interval schedule. One large reinforcer occurred at the end of each daily training session. Sessions varied in length from 20 sec to 42.66 min, but were usually the latter. Repeated generalization tests were subsequently conducted for these subjects and subjects trained with a more conventional short-random-interval schedule. The long-adjusting-interval schedule produced generalization gradients that were not qualitatively different from those produced by the conventional procedure. However, the advantages of the long-adjusting-interval schedule are: (1) greater resistance to extinction both within and across generalization tests and (2) more stable gradient slopes within and across tests.
