Sniffy experiment is a laboratory that psychologists do research on operant conditioning. On a closed operant chamber, there is a food hopper and above food hopper there is a bar, which we need to press to train the sniffy to press it in order to get the food on the food hopper. It is a experiment that needs a lot patience on it since training animals or infants to to something that they never know about it, it takes time. It depends on how you conduct it and how the object you are you training. And if you conduct on the wrong way, it may take time to let target corret it. And if the object is easy that may cause less time to training, vice versa. It is a very interesting and aware experiment that told people how to conduct and training something.
