WebThe theory of spreading activation proposes that the activation of a semantic memory node may spread along bidirectional associative links to other related nodes. Although this theory was originally proposed to explain semantic memory networks, a similar process may be said to exist with episodic or emotional memory networks. ... WebSpreading activation suggests that, when a concept is activated, the activation spreads to concepts that are semantically or associatively related to it. Thus, people often retrieve unpresented members of a category when tested on their memory for a series of presented concepts from that category.

WebActivation can spread from this node to other linked nodes in memory. When the activation of another node exceeds some threshold level, the information con- tained in that node is recalled. Thus, the strength of association between the activated node and all linked nodes determines the extent of this "spreading acti- http://pespmc1.vub.ac.be/SPREADACT.html

Web1 Nov 1992 · Spreading activation theories and compound cue theories have both been proposed as accounts of priming phenomena. According to spreading activation theories, the amount of activation that spreads between a prime and a target should be a function of the number of mediating links between the prime and target in a semantic network and … Web27 Apr 2016 · Taken together, these findings imply that activation of associations is an exploratory process by default, but is narrowed to exploiting the more immediate associations under conditions of high load. We propose a potential mechanism for processing associations in exploration and in exploitation modes, and suggest clinical …

WebSpreading activation and arousal of false memories. Explores the connections between activation processes within an interrelated network and the development of false memories. The authors first provide a brief review of the use of spreading activation metaphor in explaining phenomena beyond simple semantic priming effects. WebA Spreading Activation network (Crestani, 1997, 2000) is created for all the documents using indexing units (statistically derived) and entities (ontology-driven). The central nodes are the documents. Document nodes are connected to and from these auxiliary nodes consisting of both precise and non-precise items with appropriate weights.
