Semantic network theory (DESCRIBE)
a description of the organisation of information in long-term memory in terms of overlapping networks (grids) of interconnected concepts (nodes) ; activating one node during retrieval increases the likelihood that associated nodes become activated
Nodes
Represent the concepts. Each node is linked with a number of other nodes. As we retrieve information, the activator of one node causes other related nodes to be activated.
Pathways/Links
connect the nodes; these show how the concepts are related to one another. The length of each one represents the degree of association between two concepts. Shorter they are suggests stronger associations and therefore quicker retrieval times.
Spreading activation...
is when people think of a word, their thoughts naturally go to related words. It is assumed that activation spreads out along the pathways of the semantic network surrounding the word.
Semantic Network theory (DEFINE)
(information in LTM is organised systematically in the form of overlapping networks of concepts and units of information that are interconnected and interrelated by meaningful links.)
