大鼠被用来检查在多大程度上消除了后天的条件性味觉厌恶阻碍了随后的重新获得。将糖精味溶液（sac）与LiCl配对，然后对该风味进行单独cs消光试验。在初始条件作用和消失过程中，对照组接受了不同口味的脱咖啡因咖啡（coffe）。在第二个条件作用阶段，所有大鼠都将Sac与LiCl配对。相对于控制组对囊的厌恶的获得，对囊的厌恶的重新获得被延迟。在一个类似的实验中，较少的消退试验，但仍然完全失去了最初的厌恶，并没有获得缓慢的重新获得。从消光和慢重捕获效应的干涉角度对结果进行了讨论。
Rats were used to examine the extent to which extinction of an acquired conditioned taste aversion retards subsequent reacquisition. A saccharin-flavored solution (sac) was paired with LiCl and then followed by CS-alone extinction trials with this flavor. A control group received a different flavor, decaffeinated-coffee (coff), during initial conditioning and extinction. Sac was then paired with LiCl for all rats during a second conditioning phase. Reacquisition of the aversion to sac was retarded relative to the acquisition of an aversion to sac by the control group. A similar experiment with fewer extinction trials, but still with complete loss of the initial aversion, did not obtain slow reacquisition. The results are discussed with respect to an interference view of extinction and the slow-reacquisition effect.
