RECENCY, REPEATABILITY, AND REINFORCER RETRENCHMENT: AN EXPERIMENTAL ANALYSIS OF RESURGENCE

Four experiments were conducted with pigeons to assess the experimental conditions necessary for the occurrence of resurgence. The general procedure consisted of the following conditions: Condition 1--reinforcement of key pecking; Condition 2--reinforcement of treadle pressing and concurrent extinction of key pecking; and Condition 3--the resurgence condition wherein resurgence was defined as the recovery of key pecking.
