There are “effective strategies for dealing with information overload based on over 100 years of research on learning, memory and, more recently, information processing”. (Rollins & Zahm,2006) Environment information is received, processed and then stored by a series of processing systems. Researchers goal 's is to determine the processes and structures that allows cognitive performance and how to improve it. These processing systems interpret information in systematic ways based on previous memory information. Atkinson and Shiffrin proposed a three-stage model of memory systems explaining how information processing happens. (as cited in Rollins & Zahm, 2006, p. 87) Today a widespread number of psychologists still use a modern version of the original model. The model is divided in sensory memory stores, short-term memory stores in working memory, and long-term (permanent) memory stores. Sensory memory (first stage) activation begins through the five senses sight, hearing, smell, taste and touch. This process is automatic, meaning it does not require any conscious attention. This stage is characterized for storing big amounts of information for a tiny amount of time. This tiny amount of time is usually enough for the individual to decide if a stimuli required more attention or if it should be forgotten. Forgetting can be seen as a positive quality, a selection of important information, leaving space for new environment stimuli. Short-term memory stores in working memory (the second stage) activation begins when sensory information receives more attention. This process is not automatic, meaning it requires conscious attention. Short-term memory is characterized for storing small amounts of information for small amount of time. It “can only hold between five and nine chunks of information for a short period of time, perhaps up to 30 seconds (Baddeley, 1992; Miller, 1956 as cited in Rollins & Zahm, 2006, p. 89) ”
