Classical Conditioning Case Study

As I grew up there has always been a really good example of classical conditioning. In this case I went to Golden Corral when I was sick and before going I thought it was a smart idea to drink a big glass of milk since I love milk. Well we get to Golden Corral and while we are waiting in line my body decided to regift all that milk I drank earlier all over the floor and bottom of the wall. To this day I never go to Golden Corral because I get instantly sick to my stomach. My condition stimulus here would be the restaurant. My unconditioned stimulus is flu I had at the time. Then leaving the condition response being me getting sick at the restaurant. Unfortunately this has happen a total of 4 times, lucky for the workers the next three times I made it to the restroom. Now as soon as I step into the restaurant and automatically get sick to my stomach.
For operant conditioning the first thing that comes to mind that most kids have been through, and that is getting paid to do chores.
Simple case of kid does chore, kid gets paid. This would be an example of positive reinforcement. It gives the kid something positive such as money for doing his chores. This guarantees that his behavior towards chores should get better over time. It similar to adults going to work every day to get paycheck at the end of the month. With the kid he gets paid after doing his chores and eventually when they grow up they will do their chores without that reward, making it a fixed/variable consequence
schedule.
