Detailed explanation-1: -The rats in the pathological examination part were also shocked with 110 V of alternating current. The rats in the electrocution death group were shocked for 2 minutes. The rats in the electrical injury group were shocked for 30 s.
Detailed explanation-2: -Yoked rats can also make operant responses, but of course none of their responses effect shock avoidance. Weiss examined results from all his subjects and found that response rate effected ulceration. The more responses the animal made the greater was its ulceration.
Detailed explanation-3: -In an early version of the study, Brady placed monkeys in ‘restraining chairs’ and conditioned them to press a lever. They were given electric shocks every 20 seconds unless they pressed the lever during the same time period. This study came to an abrupt halt when many of the monkeys died from perforated ulcers.
