Information processing model or memory model

memory model is part of Cognitive Processes that are used in interface design.information process model consist of sensory,working and long term memory.these memories must be considered while designing interfaces.

2. What is your favorite food? What is the color of you’re your neighbor gate? What is the exact recent sentence of teacher in class? HIC-USA Let’s try your memory

3. Name these charters & place.. HIC-USA How much we remember about any thing?

4. It depends upon… What kind of movies you watch? If you like harry potter movie And when was the last time you have seen this movie HIC-USA

5. Information processing is the change (processing) of information in any manner detectable by an observer. As such, it is a process that describes everything that happens (changes) in the universe, from the falling of a rock (a change in position) to the printing of a text file from a digital computer system.

9. The main purpose of sensory memory is to screen incoming stimuli and process only those stimuli that are most relevant at the present time.  if HIC-USA Sensory Memory

11. This second stage is the first stop for incoming information. It holds only a certain amount of information for a brief amount of time, unless there is further processing into long-term memory. It is also referred to as one's working memory , as it serves any number of functions like remembering phone numbers, plans for the day, etc . Duration : 0-18 seconds • Capacity : 7 +/- 2 items HIC-USA Working or short-term memory

12. Executive control system The role of the executive control system is to select incoming information, determine how to best process that information, construct meaning through organization and inferences, and subsequently transfer the processed information to long-term memory or choose to delete that information from the memory system altogether (e.g., a telephone number that is no longer needed ).

13. Articulatory loop The role of the articulatory loop is to maintain and further process verbal information. V isual-spatial sketch pad The role of the visual-spatial sketch pad is analogous to the articulatory loop in that it maintains and further processes non-verbal and visual information. Information is lost quickly from working memory (i.e., 5 to 15 seconds) unless some type of mental rehearsal occurs. HIC-USA Working memory components

14. Barring rehearsal (e.g., repeating a telephone number), information is either forwarded to long-term memory or is deleted from the system . Chunking and rehearsals helps in retaining information in working memory HIC-USA Working memory components

15. The role of long-term memory is to provide a seemingly unlimited repository for all the facts and knowledge in memory. Most researchers believe that long-term memory is capable of holding millions of pieces of information for very long periods of time (Anderson, 2000).  A great deal of research has gone into identifying two key aspects of long-term memory: (a) what types of information are represented, and (b) how information is organized . there is universal agreement that qualitatively different types of information exist in long-term memory and that information must be organized, and therefore quickly accessible, to be of practical use to learners.
