Discover our productsFood-motivated operant conditioning test Progressive-ratio (PR) schedules permit studying food-motivated behavior. These schedules require an increasing number of operant responses to obtain successive rewards within a session. For example, a typical PR 5 schedule requires five responses to produce the first reinforcer, and the response requirement is incremented by five each time a reinforcer is earned. The breaking point, defined as the highest ratio completed is a classical measure reflecting the efficacy or motivational strength of food, and is increased in response to food-deprivation or reward high palatability. | Self-administration test Self administration is a classical model of human drug-taking behavior and consists in establishing in rodents an operant conditioning of an instrumental response (nose-poke, lever pressure) to obtain a reward, according to a fix or progressive ratio. Self administration is a standard paradigm for studying the acute rewarding properties of drugs, the development of habitual drug-seeking behaviors, and ultimately, addiction. Moreover, this method can be used to assess the abuse potential of drugs. | Geller Seifter test The Geller-Seifter paradigm is a conflict model in which prior food-deprived rodents have to “choose” between consuming food and avoiding the punishment associated with this consumption. Basically, periods of responding by lever pressing to get sweetened condensed milk on a variable interval schedule are interrupted by periods where, in the presence of a signal, reward can be obtained more frequently but are accompanied by mild footshocks. Levels of punished responding are inversely proportional to the level of anxiety. Then, in this context, the shock-induced reduction of reward seeking can be reversed by administration of anxiolytics. |
