Question No. 2                                                                                                                                            10 Marks      

Consider that a man is watching a picture of a Black Horse. He receives an external stimulus from input channel. Man gains some information about the picture from external environment and stores it in the memory. Once the initial information is gained, it is compared with the memory and then stores it. Finally upon perceiving and storing the information in memory Man says that the picture contains Black horse.

Based on the information-processing model, cognition is conceptualized as a series of processing stages where perceptual, cognitive, motor processors are organized in relation to one another.

You are required to identify and elaborate that which cognitive processes i.e. Perceptual system, Cognitive system, and motor system are involved when man interacts with the picture and also that which input channel is responsible in taking information to the brain.
