So if you want to use picture scales with children, how are you going to show intensity of a flavour? Visually, you have at least a couple of choices. You can make things BIGGER or show MORE of them.
If you are trying to get information about overall flavour intensity (= total flavour impact), I tend to use the bigger approach.
How much taste does this product have? The child may not be able to read the word but with interviewer assistance and clear visual differences among categories, it gives useful data.
I use the MORE option when I want to get some idea of flavours within the product (not just overall impact) and there are many ways to do that – here are a couple I have used.
These scales give broad separation of products rather than fine distinctions but can be helpful in directing further refinements to a product.
