Rats were used to examine the effects of inescapable swim stress on latent inhibition using a conditioned taste aversion procedure. Subjects were subjected to inescapable swim after each of three saccharin taste preexposures and saccharin was later paired with LiCl. The ability of swim to influence latent inhibition was assessed on subsequent saccharin test trials. Swim stress significantly attenuated latent inhibition. The implications of these results regarding the effects of swim stress on conditioned taste aversion are discussed.
使用条件性味觉厌恶程序,用大鼠来检验不可逃避的游泳应激对潜伏抑制的影响。在三次糖精味觉预暴露的每次之后,让实验对象接受不可逃避的游泳,随后将糖精与氯化锂配对。在随后的糖精测试试验中评估游泳对潜伏抑制的影响能力。游泳应激显著减弱了潜伏抑制。讨论了这些结果对于游泳应激对条件性味觉厌恶影响的意义。
