The document discusses reading as a cognitive process. It describes the two steps involved in reading comprehension as the extraneous process which creates visual stimuli in the brain, and the fusion and interpretation of meaning from those stimuli by the mind. It also outlines the complex mental activities involved, such as word recognition, attention, association, synthesis. Finally, it discusses the four levels of comprehension - literal, interpretative, applied, and evaluative - and defines the SQ3R method of reading.
