Reading and the Science Behind It

Reading is both a hobby and an exercise. Though the reader might appear passive, his or her mind is continually working, and hence, reading can be considered an exercise of the mind. The style of reading varies across stages, and each stage involves different levels of information analysis. A reader might just skim through a text looking for a few words, or he or she might read it completely to gain a greater depth and breadth of knowledge.
When reading a novel or a short story with a particularly intriging plot, the reader does not hesitate to read an entire page. However, this is often not the case while reading a newspaper. People prefer simply scanning through the headlines. As a result, the level of concsiousness depends on the reading material. Most often, newspaper writing is simple and straightforward. This demands less attention. A work of fiction may involve a complex plot and sophisticated language, which provoke the reader to think.
