Oftentimes, beginning writers overwrite, putting too much details, exposition and explanations in their projects. The other side of the spectrum is underwriting: not enough detail let the reader float in space. Overwriting is usually easy to spot. Underwriting is usually not so easy in that to put your finger on. Whatever, the obvious question is how to find the "right" balance, if there is such thing at all in the first place. Does anyone know about research done on this subject? I can find neurological articles on how the brain works, but haven't find any on how the mind works while reading a work of fiction. Maybe I use the wrong terminology. Any hints would be much appreciated.
