Un problema de la Psicofísica particularmente relevante para el estudio de procesos de condicionamiento es el de la re lación entre las propiedades de refuerzo y físicas de los es tímulos. Papi ni y Pellegrini (2006) observaron que el nivel de re

Three experiments explored the role of the opioid system in consummatory successive negative contrast. In Experiment 1, rats treated with the nonspecific opioid-receptor antagonist naloxone (2 mg/kg) exhibited increased suppression after a shift from

Rats given access to a 32% sucrose solution later reject a 4% solution significantly more than controls that have only received the 4% solution. In Experiment 1, this consummatory successive negative contrast (cSNC) effect was attenuated by previous

In two experiments, rats were placed in a conditioning cage for 5 min per day under two conditions, pre-shift (10 days), in which half of the rats were given access to a high-value reward (Experiment 1, 32% sucrose solution; Experiment 2, sweet solid

Differencing is a very popular stationary transformation for series with stochastic trends. Moreover, when the differenced series is heteroscedastic, authors commonly model it using an ARMA-GARCH model. The corresponding ARIMA-GARCH model is then use

Paradoxical extinction effects in the conditioned consummatory behavior of rodents have remained largely elusive. Here, appetitive flavor conditioning was studied to determine if a paradoxical magnitude of reinforcement extinction effect (MREE) can o

The reduced form of the local level model with conditionally heteroscedastic GARCH(1,1) noises is analyzed. We show that the IMA-GARCH model is a good alternative but its conditional heteroscedasticity is weaker than this of the unobserved disturbanc

Rats exposed to incentive downshift show behavioral deterioration. This phenomenon, called successive negative contrast (SNC), occurs in instrumental and consummatory responses (iSNC, cSNC).Whereas iSNC is related to the violation of reward expectanc
