Etude du conditionnement rétrograde dans une procédure de renforcement conditionné

Abstract : In human and non-human animals, environmental stimuli that reliably accompany the presentation of significant events are able after repeated exposures of eliciting anticipatory behaviors. Many authors underlined the adaptive value of anticipatory responses, and suggested a connection with Pavlovian conditioning. Linking anticipatory behaviors to Pavlovian conditioning is supported by the similarity in procedure (i.e. a pairing between a neutral stimulus with a significant event), but also on the common effects and phenomena, and the authors assume that Pavlovian conditioning is the process underlying the anticipation of events. This assumption is at the heart of the Information Hypothesis, and more generally of a functional and predictive perspective of Pavlovian conditioning. According to the Information Hypothesis, Pavlovian conditioning only occurs when an unexpected significant event is presented, and learning (i.e. the formation of association) would be about stimuli that allow the anticipation of the significant event. Using a backward conditioning procedure in a conditioned reinforcement preparation, we tested the assumptions made by the Information Hypothesis. The results found argue against the Information Hypothesis and, in contrast, support the assumption made by two others types of leaning models, illustrated by the Temporal Coding Hypothesis and the SOP model. The Temporal Coding Hypothesis and SOP are tested in a third experiment. Implications for Pavlovian conditioning models and anticipatory behaviors in general are discussed.
