Abstract
Young and adult rats were given nonreinforced exposures to the flavor-CS prior to a taste aversion conditioning session. CS-preexposure prevented the conditioning of a taste aversion in young rats but only attenuated conditioning in adults. These results suggest that an enhanced CS-preexposure effect may account for the previously reported weaker conditioned taste aversion observed in young rats, as compared to adults, when there is a protracted interstimulus interval.
摘要
在进行味觉厌恶条件反射实验之前，对幼年和成年大鼠进行了无强化的味觉条件刺激（CS）暴露。CS预暴露可防止幼年大鼠形成味觉厌恶，但仅减弱成年大鼠的条件反射。这些结果表明，与成年大鼠相比，当存在较长的刺激间隔时，幼年大鼠先前报道的较弱的条件性味觉厌恶可能是由于增强的CS预暴露效应所致。
