Why can certain fruits make my mouth water before even biting into them?

Read up on Pavlov ’ s dog. It’s mental programing. Psychological conditioning.

I found this article that says humans don’t work like Pavlov’s dog.
But I would have to disagree. I do not salivate for regular food, but I do with fruits. I always thought it may be because fruits can be a bit acidic and maybe I am reacting to the acid in them. Even if I haven’t bitten into them yet.

Haha…as I am eating a big bowl of mixed fresh watermelon, strawberries and mandarin oranges. I think it is an association thing especially if the fruit is tangy, apples probably don;t cause the effect but citrus and strawberries do for me.

The same reason women will leak milk when they hear their baby cry. The brain reacts to situation to prepare us for what is required.

Saliva helps break down sugars. Sugars actually start to be digested/absorbed in the mouth.

I also was going to cite Pavlov, I see that was done above. I absolutely think humans have characteristics that fit into the Pavlov model.

I agree with JLeslie, our brain simply reacts on colors in a certain fashion.

It’s a question of our subconscious mind, not a voluntary decision. Here is a great website that I love to share with people interested in that subject.
