Activity 5.4


The dual memory model of information processing is the theory of how the human brain processes information.  Information (input) enters the brain through sensory registers (sight, hearing, taste, touch, and smell) through attention and perception the information may move to short-term memory (conscious thought).  Once in short-term memory it only remains for several seconds, and if connections are made it may move to long-term memory.  The information stays in the long-term memory (repository of knowledge) where it connects with other schemata (knowledge structures).  The process of retrieval happens when a cue or connection assists in bringing the information to the conscious.  According to Mayer (2012), the information processing model is critical to the instructional environment because it facilitates the cognitive learning process.

The Internet is changing the way we process information and how the brain functions. The mind quickly processes information while browsing, scrolling, and linking from page to page.  People use the Internet to socialize, shop, research, take classes, communicate, work, pay bills, and connect in every way possible.  This multitasking environment is viewed by many as an efficient way to achieve more in less time, and the availability of electronic devices makes it possible.  Rosen (2008) explains that media multitasking is resulting in a loss of productivity, loss of time, negative impact on learning, and diversion of attention.   

The electronic technology is creating a change in the way people interact and learn.  “Of all the sacrifices we make when we devote ourselves to the Internet as our universal medium, the greatest is likely to be the wealth of connections within our own minds” (Carr, 2011, p. 195).  The Internet may be a great supplement or complement to memory and learning, but it does not replace the complex biological process that happens in the brain when learning occurs.  Carr (2011) describes the Internet as the source for creating a habit of behavior in how information is processed that is detrimental to the full function and utilization of the brain.  Supporting the importance of the cognitive function of information processing James (1899/2001) states, “the more copious the associative systems, the completer the individual’s adaptations to the world” (p. 42).  In order to operate fully and efficiently in society one must keep in mind “…the art of remembering is the art of thinking…” (James, 1899/2001, p. 70).

The Internet is creating a culture of people who are outsourcing their memory to the computer.  The implications this may have for learning include an increased lack of attention, faulty memory, lack of interest, and the change of habits (that are not as productive).  In addition, the reliance on the computer is decreasing the ability to think deeply and make connections and associations that translate into meaning.  As Pinker (2002) noted, the human brain is critical in the individual’s ability to prosper in the world’s complex environment.  The computer has often been used as a metaphor for the brain, and now there are signs that the computer is becoming a substitute for many of the functions of the brain.
