I would be curious to see how long it took the various dogs to figure out the initial negative/positive bowl locations depending on if they fell into the "pessimistic" and "optimistic" category.
Haha, it's one of the first things I decided I wanted to measure. It's easy enough to teach your own dogs the same task they used in the study. I started teaching Kivi and Erik a variation of it to give me an idea of how long the training would take. It was super interesting before I got as far as even teaching them to discriminate between "good" and "bad". Even when Erik figured out the game and that one bowl would have milk and the other water, he still checked the water every time just in case it wasn't water this time. He even tasted it every time, just in case it smelt like water but wasn't. In contrast, Kivi wouldn't even bother checking the other bowl when he found the milk. Kivi is pretty keen on food.
Even more fascinating, my first attempt I tried on Erik because he's a persistent little beggar involved a bitter-tasting additive to the milk instead of just plain water. It was obviously too aversive even for Erik, because he decided he didn't want to play before he worked out how to avoid the bitter milk. When I tried again a week later with milk and water, he was outrageously jumpy about tasting either, but he did it anyway. I couldn't believe that he was acting like he expected it to not only taste horrific but leap out of the bowl and attack him, yet he still tasted it. Now that's optimism. I imagine if I'd tried Kivi with the bitter stuff he'd never participate in one my experiments ever again. He is generally not an optimist, but you should see the way he approaches strange dogs. He is pretty optimistic about making new friends. Interesting to think a dog might be inherently optimistic about some things, but pessimistic about others.
