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.

大鼠选择性食物贬值后时间平分的非对称效应

本研究调查了选择性食物贬值对大鼠时间二等分手术性能的影响。差异结果（蔗糖与谷物颗粒）与短期和长期的正确反应相关，以分析选择性持续时间特定的食物贬值对时间平分函数的影响。选择性预喂产生不同的响应比例、 p(long) 函数和 PSE 的变化。当锚定时间长的食物贬值时，观察到的影响比锚定时间短的食物贬值时更一致。讨论了与偏差和选择短期效应相关的结果。
