Dr. J's sоn lоves bаsebаll. He plаys baseball as much as he can. We all try tо make his experience and fun and help him improve in the game he loves. HIs coach tries to make practices fun by using operant conditioning. When Eli strikes a player out in a practice game, the coach adds a twizzler to this pail of treats in the dugout. When a player gets a hit off Eli, he makes Eli run one lap around the entire baseball field as an immediate consequence. Eli's mother is different, she gets so excited when he gets a hit that she goes home that night and does Eli's chores so he can take a bath and go to bed to rest. When Elis mother takes away him having to do his chores so that he is motivated to give his best effort in baseball, what type of operant conditioning is being utilized?
