We can process information in 3 ways: Shallow Processing - This takes two forms 1. Structural processing (appearance) which is when we encode only the physical qualities of something.  E.g. the typeface of a word or how the letters look. 2. Phonemic processing – which is when we encode its sound. Shallow processing only involves maintenance rehearsal (repetition to help us hold something in the STM) and leads to fairly short-term retention of information.  This is the only type of rehearsal to take place within the multi-store model. Deep Processing - This involves 3. Semantic processing, which happens when we encode the meaning of a word and relate it to similar words with similar meaning. Deep processing involves elaboration rehearsal which involves a more meaningful analysis (e.g. images, thinking, associations etc.) of information and leads to better recall. For example, giving words a meaning or linking them with previous knowledge.

A University of California Los Angeles team found searching the web stimulated centres in the brain that controlled decision-making and complex reasoning

"Internet searching engages complicated brain activity, which may help exercise and improve brain function."

The researchers said that, compared to simple reading, the internet's wealth of choices required people to make decisions about what to click on in order to get the relevant informat
