International audience. 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.
