Spreading activation models

WebSpreading Activation Model. model that accounts for response times by formulating assumptions about how activation spreads in a semantic network - color red is more closely related to other colors and less closely related to red objects making it account for typicality effect by having the links represent different degrees of semantic relatedness. WebThe Spread of Activation (SA) model in its pure form is quite simple. It is made up of a conceptually simple processing technique on a network data structure. The network data structure consists of nodes connected by links, as depicted in Fig. 1. Nodes model objects or features of objects of the real world to be represented.
