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 ...
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-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 ...
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 ...
