Extinction and reinforcement of alternative behavior

Examined the course of extinction of 1 behavior as a function of the presence and subsequent absence of reinforcement for alternative behavior. 4 experiments were conducted, using a total of 102 male hooded rats in 3 experiments and 30 adult White Carneaux pigeons in the 4th. Major findings are: (a) Topography and reinforcement schedule for alternative behavior had little differential effect. (b) High-frequency reinforcement of alternative behavior increased suppressive effects of extinction, and low-frequency reinforcement did not. (c) Reinforced alternative behavior maintained for a relatively long period decreased subsequent recovery of the original response programed for extinction, resulting in a substantial saving in total number of extinction responses. (d) Temporary reinforcement of alternative behavior produced more permanent suppression in the context of simple extinction than in the context of SD (change in stimulus) periods in discrimination learning.
