Chunking is stepping between levels of specificity.
Changing your perception by going up or down a logical level.
Stepping up means going up to a level that includes what you are studying.
Stepping down entails going to a level below for a more specific example of what you are studying.
With other words; to chunk up means to move to the bigger picture, to chunk down would be getting to greater levels of specificity.
We can do this on the basis of member and class, or part and whole.
