The relationship between value and temporal context is an empirical question: A reply to Fantino (2000)

E. Fantino (2000) argued that R. C. Grace and H. I. Savastano's (2000) expe riments fail to elucidate the relationship between stimulus value and tempo ral context. His reasoning is that predictions for R. C. Grace and H. I. Sa vastano's probe tests based on delay-reduction theory (DRT) and the context ual choice model (CCM) are indistinguishable. However, his method of applyi ng DRT to the probes ensures that temporal context will have no effect on w hich stimulus is preferred, contrary to the core principle of that theory. The only basis for differential responding in the probes is baseline traini ng, and R. C. Grace and H. I. Savastano's data clearly show that the termin al-link schedules, independent of temporal context, control choice in the p robes, as predicted by CCM.
