Abstract
Procedures for producing rapid and reliable lever-press Sidman avoidance acquisition in 100% of an unselected group of rats are described. Groups of 12 rats were exposed to schedules with an R-S interval of 20 sec., at S-S (shock-shock) intervals of 1, 3, 5, 10, and 20 sec, with a constant power shocker. 1st session response levels were a monotonically decreasing function of S-S interval. The hypothesis that acquisition probability is due to reduction of shock frequency was supported, but acquisition levels of responses with spaced IRTs (interresponse times) were unrelated to S-S intervals.Keywords
