jumping stand

a type of apparatus formerly used to study discriminations. Rats were placed on a stand and had to obtain food by jumping through doors on a platform some distance away. Usually two doors were present, each displaying a distinctive stimulus. Jumping through one door (designated as correct) led to food. Jumping toward the other door, which was locked, led to a fall into a net. The apparatus has been abandoned because too many variables were left uncontrolled.
