Maintainability is a very important issue (or at least its high
cost is).  Maintenance is done by people and so cognitive factors
are likely to be the dominant factors.

Exactly which cognitive factors are dominant and their impact on
maintenance costs is something of an unknown.  So you have plenty
to research.

You are just starting out on your research and I would recommend
that you base it on the results of experiments and measurements.
To much existing research is based on theoretical discussions
of 'interesting' ideas.  This is a complete waste of time.
