Rôle du conditionnement dans l’effet placebo
Conditioning is a useful tool to analyse associative learning processes in many different species. This is especially obvious in psychopharmacology, where it is regularly observed that the affective effect (aversive/appetitive) of a drug can enter into association with the surrounding environmental stimuli. Such a conditioning processes (associative learning) allows us to better understand various phenomena like opites-induced tolerance or withdrawal syndromes. Moreover, conditioning seems to play a crucial role in the placebo effect, at least, as it is observed during analgesia. The purpose of the present analysis is to have a closer insight into modern theories of associative learning and their impact on the effects of opiates. Ultimately, we will discuss the placebo effect during analgesia in the framework of conditioning processes.
