How do you think about Long-term Memory?

1.      Types of knowledge stored in long term memory
            Long term memory (LTM) is a more permanent, apparently limitless store, containing all our knowledge of the world and memories of the past. Information can be difficult to retrieve from long term storage – retrieval cues need to closely match the way the memory was encoded into LTM.
The kind of memory involved in these situations is long-term memory, information that is acquired in the course of an experience and that persists so that it can be retrieved long after the experience is past. As we will see, some forms of long-term memory can be consciously retrieved, so that we can use our remembrance of things past to guide present thought and action. William James (1890) described this kind of memory as “the knowledge of a former state of mind after it has once dropped from consciousness.” By contrast, other forms of long-term memory influence our present thinking and behavior while operating outside awareness. In such instances, past experience unconsciously affects the present. Progress in understanding longterm memory has come from behavioral investigations of people with intact memories as well as of patients with memory deficits. Insights into the operation of memory also have come from lesion and recording studies in animals and neuroimaging studies in humans.
The characteristics of long-term memory are: 
1.     LTM stores all the information we process  but are not immediately using. Storage of information is believed to be permanent.
2.     Forgetting is the inability to retrieve or locate information, rather than the loss of  information.
3.     Information enters the LTM from the WM  and must be classified, organized, connected and stored with information  already in LTM if you want to retrieve it easily later. It takes time and effort to  move information into the LTM.
4.     Prior knowledge plays an important role in  learning. The more information you know before going in to lecture the easier it is to  take notes and understand.
5.     To keep knowledge fresh and accessible,  means you have to have a good processing system in place.
6.     You should be continually updating and revising your mental ‘filing closet’.
