Alcohol
Consumption in a Non-contingent, Appetitive Situation

Little work
has been done to
examine the effects of stress on voluntary alcohol consumption in rats.
The
present study utilized eight rats, which were trained to bar press on
an FR1
schedule of reinforcement. They were then put on a VI30 schedule of
reinforcement followed by a FT60 schedule of reinforcement. Alcohol
consumption
was measured over a 24 hour time period following each session of
reinforcement. The next phase was the extinction phase, during which
time no
reinforcement was given and alcohol consumption was measured. The
results show
that as a model of learned helplessness in an appetitive situation was
established, through non-contingent delivery of food followed by a
period of no
reinforcement alcohol consumption increased. |
