Description
SANS Automated Shuttle Avoidance Box is a flexible system for active avoidance, passive avoidance and learned helplessness experiments. It comes with two independent chamber with grid floors that allow for flexible
adverse stimuli. Automatic door is integrated in the chamber for auto opening and closing to reduce the influence of human interaction during the experiment.
A top-loading door allows easy access inside the box. The chamber contains a sound generator and a visual stimulus (light) that functions separately for each compartment. Software be used through PC connection.
Shuttle Avoidance Test
When an aversive stimulus is applied, the subject learns to avoid the aversive stimulus by moving to the other side of the two-compartment chamber after the presentation of the stimulus.
Passive avoidance Test
After the motivation or training, the subject is forced to move to the preferred side of the two-compartment chamber. Then it confined to the dark portion of the chamber, and experiences inescapable aversive stimulus.
Learned Helplessness Test
Learned helplessness is the behavior exhibited by a subject after enduring repeated aversive stimuli beyond their control. When a subject is place in an inescapable aversive stimulus environment (i.e. electric shock), it will develop a kind of despair behavior, which is manifested as no longer avoiding the stimulus and interfering with subsequent adaptive responses.
