“…There was evidence for summation in freezing during the first Stage II trial: freezing was significantly higher to the first presentation of the compound CS as compared to the average responding observed to the individual CSs at the end of Stage I, F(1, 34) ϭ 16.4, p Ͻ .05. This is a liberal criterion for assessing summation (e.g., Aydin & Pearce, 1997;Lattal & Nakajima, 1998;Rescorla, 1997), but a similar significant difference in freezing was observed when the first compound trial was compared to the final Stage I presentation of the visual, F(1, 34) ϭ 12.2, p Ͻ .05, or auditory CS, F(1, 34) ϭ 12.9, p Ͻ .05.…”

Six experiments studied the role of GABA A receptor activation in expression of overexpectation of Pavlovian fear conditioning. After separate pairings of CSA and CSB with shock in Stage I, rats received pairings of the compound AB with shock in Stage II, producing overexpectation of fear. The expression of overexpectation was attenuated, in a dose-dependent manner, by the benzodiazepine partial inverse agonist FG7142. FG7142 had no effect on responding to a CS paired with a low magnitude US or a CS subjected to associative blocking. These results suggest that the negative prediction error generated during overexpectation training may impose a mask on fear rather than erasing the original fear learning. They support claims that overexpectation shares features with extinction.

“…Nevertheless, overexpectation effects have been found in studies on Pavlovian fear conditioning in rats (Blaisdell, Denniston, & Miller, 2001;Kremer, 1978;Rescorla, 1970), appetitive conditioning in rats (Lattal & Nakajima, 1998;Rescorla, 1999) and autoshaping with pigeons (Khallad & Moore, 1996). Furthermore, overexpectation is predicted from the Rescorla-Wagner model, and counts as one of its most notable successes (Miller, Barnet & Grahame, 1995).…”

The purpose of this monograph is to examine the relationship between a particular artificial neural network, the perceptron, and the Rescorla-Wagner model of learning. It is shown that in spite of the fact that there is a formal equivalence between the two, they can make different predictions about the outcomes of a number of classical conditioning experiments. It is argued that this is due to algorithmic differences between the two, differences which are separate from their computational equivalence.A peer-reviewed monograph published by Comparative Cognition and Behavior Reviews on behalf of the Comparative Cognition Society.

Pavlov's first report on conditioning emphasized its role in allowing the animal to adjust to its environment. Contemporary theories have seen this adjustment in terms of developing accurate knowledge of the environment. Three aspects of that thinking are explored: how the animal acquires initial knowledge, how it changes its knowledge when conditions of the world change, and how it makes use of multiple knowledge representations. Keywords: error correction, overexpectation, superconditioning, extinction, modulation, Rescorla-Wagner model El primer informe de Pavlov sobre el condicionamiento subrayaba su función para la adaptación al ambiente. Las teorías contemporáneas han contemplado esta adaptación en términos del desarrollo de un conocimiento adecuado del medio ambiente. Se exploran tres aspectos de esa línea de pensamiento: cómo el animal adquiere el conocimiento inicial, cómo modifica su conocimiento cuando cambian las condiciones del medio y cómo hace uso de representaciones múltiples del conocimiento. Palabras clave: corrección de errores, sobreespectativa, supercondicionamiento, extinción, modulación, modelo de Rescorla-Wagner
