Proactive interference of open field on consummatory successive negative contrast

摘要: Reactivity to a reward is affected by prior experience with the different reinforcer values of that reward, phenomenon known as incentive relativity, which can be studied using consummatory succesive negative contrast (cSNC) paradigm, in performance animals receive 4 % sucrose solution after trials on they were exposed 32 compared subjects always solution. The exploration novel open field enhance or block acquisition associative and nonassociative memories. effect cSNC has not yet been explored. main result present study was open-field exposure significantly modified expression cSNC. Exposure an 1 h but immediately before downshift interfered These drank more downshifted than did controls apparatus, this behavior persisted for up three recovery trials. This observed even when given protracted preshift phase discrepancy between shift increased. An also occurred 6 downshift, repeated apparatus deteriorate effect. adds growing body literature indicates interfere memory formation.
