People who haven't learnt to draw (and I'd include all the children in this except possibly Nick and Matt) tend to draw symbols instead of accurate representations. So, what's the symbol for a scientist? A lab coat. What's the symbol for a lab coat? A white coat shape, with buttons down the front. The children are about ten years old, right? So, despite their lack of skill in seeing, they have the dexterity to draw what they want to draw, and so you'd expect them to draw similar body sizes, in approximately the right proportion (except for the eyes which we tend to perceive as 1/3 of the way from the top, when in fact they are the midpoint.)
