Modern versions of the test are less severe. Water deprivation is 18 hours or water is provided for 1 hour a day for four days before beginning the test. Electrical shock is only given for a 3-5 minute time period. [3] The VCT can be done with food deprivation too. Before beginning the test animals must be acclimated to the cage and food pellets.
