  2. Information in LTM is organized and associated with other info in LTM and it's organized in a hierarchal structure with overlapping networks of concepts connected by meaningful links. Each concept or NODE is linked with other nodes, so activating one node will activate another. When retrieving information from LTM, we begin by searching for a region of memory and tracing it back to other areas that are related. The shorter the links between nodes means the association is stronger, and stronger associations mean faster activation (retrieval) of information. The modified semantic network theory explains spread activation – activation of one node increases the likelihood of other nodes being activated. Again, the shorter the links, the stronger the associations and the faster the activation and retrieval. Longer links take longer to be retrieved.
