The present study investigated the effects of selective food devaluation on performance in the temporal bisection procedure with rats. Differential outcomes (sucrose vs. grain pellets) were associated with correct responding for a short and a long duration in order to analyze the effects of a selective duration-specific food devaluation on the temporal bisection function. Selective prefeeding produced differential changes in proportion of responding, the p(long) function, and PSE. A more consistent impact was observed when the food associated with the long anchor duration was devalued than when the short anchor duration food was devalued. The results are discussed in relation to the bias as well as a choose-short effect.
本研究调查了选择性食物贬值对大鼠时间二分法实验表现的影响。不同的结果（蔗糖与谷物颗粒）与短时长和长时长的正确反应相关联，以便分析选择性时长特异性食物贬值对时间二分法功能的影响。选择性预喂在反应比例、p(long)函数和PSE方面产生了不同的变化。当与长锚定持续时间相关的食物贬值时，比与短锚定持续时间相关的食物贬值时观察到更一致的影响。研究结果结合偏差以及“选短效应”进行了讨论。
