Spreading activation models
WebI think you’re mostly correct. From what I remember about semantic network, it’s linked both to spreading activation as well as cognitive economy principle. I think the semantic network just describes the structure you mentioned and then it’s used to explain a variety of cognitive models (spreading activation, cognitive economy, etc.).

Web2 Oct 2024 · Spreading activation models generally assume that when information is encoded in memory it is also incorporated into a semantic network. In other words, information can be considered as being organized around semantic similarities. If this is the case, then the extent to which any one concept primes activation of another is a function … WebThe results presented in this thesis contribute to a greater comprehension of the behaviour of Dell's (1986) influential model, and further demonstrate that the model can be extended to account for new instrumental evidence, whilst clarifying the constraints on activation flow between phonemes and features which this new evidence imposes.
