An apparatus int he form of a + that is elevated off the floor. Two arms are walled and two of the arms have no walls, it's placed in an illuminated room.
In general undrugged rats prefer to be in the walled space, rather than out in the open.
Anxiolytics alter rats' preference for the arms, leading to a substantial increase in the amount of time spent in the open arms.
Thus a drugs anxiolytic properties can be measured by the rats time in and out of the unwalled arms.
What is the Geller-Seifter Procedure?
A test for anxiolytic properties in drugs.
Rats are kept in a box with a schedule of reinforcement, The VI (Variable Interval) 2 minute schedule dictates that a reinforcer (food) becomes available every 2 minutes, and if the animal presses the lever after two minutes it gets a reward.
FR (Fixed Ratio) 1 with shock dictates that EVERY bar press results in food but also produces a shock...
Each schedule is signaled to the rat with a colored light, and the schedules are never both present at the same time. In this way rats learn quickly to bar press when VI 2 is in effect and not to bar press when FR1+shock is in effect.

Anxiolytics cause rats to bar press even when FR1+shock is in effect, this effect is exclusive to anxiolytics; pain killers and other drugs do not produce it, only those with anti anxiety effects.
