Learned Helplessness


  • Various dividers for two-compartment paradigms with/ without gate


This paradigm evaluates motivational and depressive states of mice and rats. Learned helplessness is induced by exposing the animal to unpredictable inescapable foot shocks during a pre-exposure session. Following such pre-exposure, animals show deficits in acquiring a subsequent avoidance task. This response deficit is called "helpless" behavior - the lack or reduction of responses presumably occurs due to a learned perception of uncontrollability, which may improve under antidepressant treatment.

The learned helplessness module of the Multi Conditioning System belongs to the family of “2-compartment paradigms”, operated with a universal software package granting maximal user-friendliness and offering unsurpassed flexibility.
