在两个实验中，我们研究了条件刺激（CS）与不同的非条件刺激（USs）在连续实验阶段相关联的两种条件反射范式中，保留间隔对表现的影响。实验1旨在检验厌恶-食欲转移，其中CS与休克和食物相关；实验2旨在检验食欲-厌恶转移，其中CS与食物和休克相关。厌恶和食欲条件反应（分别是冻结反应和头跳反应）从录像带中进行评分。在这两个实验中，在第2阶段结束后的28天保留间隔导致第1阶段反应的恢复和第2阶段反应的再抑制。结果表明，在第二阶段，当CS与新的US相关联时，原有的关联并没有被破坏。他们还认为，回溯和主动干扰效应都可能是由于对性能输出的干扰，而不是在目标阶段学习或存储的内容的中断或损失。
In two experiments with rat subjects, we examined the effects of a retention interval on performance in two conditioning paradigms in which a conditioned stimulus (CS) was associated with different unconditioned stimuli (USs) in successive phases of the experiment. Experiment 1 was designed to examine aversive-appetitive transfer, in which the CS is associated with shock and then food; Experiment 2 was designed to examine appetitive-aversive transfer, in which the CS is associated with food and then shock. Aversive and appetitive conditioned responses (freezing and head-jerk responding, respectively) were scored from videotape. In both experiments, a 28-day retention interval following the end of Phase 2 caused a recovery of the Phase 1 response and a resuppression of the Phase 2 response. The results suggest that the original association is not destroyed when the CS is associated with a new US in Phase 2. They also suggest that both retroactive and proactive interference effects may result from interference with performance output rather than a disruption or loss of what is learned during or stored from the target phase.
