One of the most prominent theories of semantic processing is the spreading activation (SA) model (e.g., Anderson, 1983; Collins & Loftus, 1975; Collins & Quillian, 1969).

WebAnother type of memory storage, the semantic matrix, is used to explain the semantic effect associated with memory recall. Spreading activation is a theory proposed that relates storage of memories to the activation of a series of nodes. These nodes create an activation pattern of other related nodes and this is how singular events are remembered. WebIt was first incorporated into a model of memory by Quillian (1967); this model was elaborated and extended by Collins and Loftus (1975). Spreading activation models also were proposed by Anderson (Anderson, 1976, 1983a, 1993), and spreading activation mechanisms were discussed by Posner and Snyder (1975a).
