When I put a boundary around something I make it more obvious where in the scene that I want you to look.
When I add a layer to something that you are familiar with you know to look at it because it doesn’t belong there (Laminated visual sentence that sticks to a normal book using velcro on both the sentence and the book, so that when you touch your hands on the book you know something is there that is not normally there).
If I make a certain facial expression it ‘suggests’ a certain emotional tone. Yet I can still see that it IS a tiger despite the fact that the rest of its body is hidden.
If I position myself at a certain angle this can allow me to see the entire size of something. Which also allows me to compare its size to other things.
Regardless of whether its 2D or 3D, whether its a sticker, whether its lego or whether its a plastic toy. It still is a pig. So when I am playing with a pig, despite whatever my hand control is, it is very clear to me that I am still playing with a pig.
The way some toys are presented visually can make it challenging to tell what something is. So you need to use the objects around it or really look at its shape definitions very clearly to see exactly what it is. Only then might you be able to tell that this is a cat, and that this is a cow.
