Hence, although the writers who co-operated to produce this page exist, they can only be represented by the signs actually selected and presented here. The interpretation process in the receiver's mind may attribute meanings completely different from those intended by the senders. But, why might this happen? Neither the sender nor the receiver of a text has a perfect grasp of all language. Each individual's relatively small "stock" of knowledge is the product of personal experience and their attitude to learning. When the audience receives the message, there will always be an excess of connotational meanings available to be applied to the particular signs in their context (no matter how relatively complete or incomplete their knowledge, the cognitive process is the same).
