What are the pros and cons of colouring-in (as opposed to freehand drawing) for pre-school and primary age children?
I'm asking in response to this question: At what age should I tell my child to colour within the lines? where it looked like there was an interesting discussion kind of 'waiting in the sidelines' but a bit off-topic for that specific question.
When I was a kid my parents avoided colouring-in - I remember the good old 'anti-colouring book' - but it's not something I've ever thought about in a lot of depth.
I know the standard criticism is that it inhibits creativity in drawing - but is that true? What's the research evidence, for and against? Maybe there are other pro and cons that I'm not aware of (e.g. perhaps it encourages fine motor skills).
