Information Processing Model

Information Processing Model 

1. Decision making within an information-processing framework to the representation of stage-based approach / ecological approach and cognitive ergonomics . 
2. Ecological approach tends to be more specifically applied to human interaction with physical systems and environments ; Cognitive engineering is relevant to the design of almost any system about which human operator can acquire knowledge , and computer systems .
3. A certain number of mental processes involved in selecting , interpreting ,retaining , or responding to information may be implemented , and it is understanding the vulnerabilities of these processes and capitalizing , provide an important key to effective human factors of system design . 
   
4. Stimuli or events are sensed and attended and that information received by our sensory system is perceived , that is , provided with some meaningful interpretation based on memory of past experience . that which is perceived may be responded to directly , through a process of action selection and execution . Alternatively , it may be stored temporarily in working memory , a system that may also be involved in thinking about or transforming information that was not sensed and perceived but was generated internally .Working memory is of limited capacity and heavily demanding of attention in its operation but closely related to our large-capacity long-term memory , a system that stores vast amounts of information about the world , including both facts and procedures ,and retains that information without attention but not always fully available for retrieval . actions generally produce feedback which is then sensed to complete the closed-loop cycle .

                                      

At last , we have a role-playing activities : a dog find a man ride bike and start to chase ( event or stimuli ), the man find the dog ( Senses ) , he think he can`t bit by the dog ( perception ) , so he decide to ride the bicycle faster ( response selection ) , he think if  I ride faster ,but the dog run faster , should I change my way ( working memory ) , he choose a road with few cars ( long-term memory ) , after the decision , he start to ride on that road ( response execution ) , at last , he got rid of the dog ( feedback ) .
