Density dependent extinction : phase II
(1993)In two separate experiments, an 8 rat 8 station operant arena was used to study resistance to extinction to test learning and optimal foraging theories of behaviour. The learning theory, called the generalized decrement ... -
Effect of prenatal cadmium exposure on development and behavior of selectively bred genetic lines of rat
(1988)PELLETIER, M. R. (1988). Effect of prenatal cadmium exposure on development and behavior of selectively bred genetic lines of rat: The purpose of the study was to investigate the effects of cadmium exposure as related ... -
Ethanol-morphine interactions : a study of the effects of prenatal exposure on the development and behavior of the rat
(1989)Ethanol-Morphine interactions: a study of the effects of prenatal exposure on the development and behavior of the rat. The purpose of the study was to investigate the effects of ethanol, morphine and ethanol-morphine ... -
Pre- and postnatal effects of nicotine on the development and behavior of rats
(1987)The effects of nicotine administered during one of three gestational trimesters on development and behavior of rats were investigated. Pregnant female SHS (Satinder's Heterogeneous Stock) rats were injected subcutaneously with ... -
Risk sensitive foraging by rats in the operant arena
(1988)The operant arena was used as the framework in which to study the theory of risk-sensitivity, A small colony of hooded rats was exposed to increasing work demands while given the choice between simultaneous fixed ratio ... -
Risk-sensitivity in a rat population under interval schedules of reinforcement : open and closed economies
(1995)A group consisting of eight male Hooded rats was tested for risk-sensitive foraging preferences in an eight station operant arena, under conditions of open and closed economies. The group could choose to forage at either ... -
Social facilitation of extinction in rats
(1991)Theories of resistance to extinction such as the generalized decrement theory (GDT) have been largely based on research involving isolated individuals. In the natural environment however, extinction, like acquisition ... -
Variable interval schedule control of dispersion and density
(1984)The effects of Variable Interval (VI) schedules of reinforcement on the dispersion patterns and aggregate densities of a small population of rats was studied. Eight male rats were permanently housed in an arena in which ...
