Semantic graphs and associative memories

Physical Review E, 2004
Graphs have been increasingly utilized in the characterization of complex networks from diverse origins, including different kinds of semantic networks. Human memories are associative and are known to support complex semantic nets; these nets are represented by graphs. However, it is not known how the brain can sustain these semantic graphs. The vision

Neural mechanisms of semantic memory

Current Neurology and Neuroscience Reports, 2004
Using previously published functional magnetic resonance imaging work studying object recall as a framework, we describe the spatial and temporal properties of brain activation as one plausible model of visually triggered access to semantic memory. We suggest that interactions between the dorsomedial thalamus and Brodmann area 6 facilitate the setting ...

Activation of Semantic Memory

The American Journal of Psychology, 1973
that the retrieval process consisted of at least two major steps: (a) entering the appropriate category and (b) finding the appropriate member of that category. Suppose now that we ask a subject to name a member of a category, and some time later ask him to name a different member of that category.

Quantification and semantic memory

Cognitive Psychology, 1975
Two models are considered for how people verify explicitly quantified sentences, such as All fathers are parents and Some fathers are parents. The models share the same second stage, but have different first-stage mechanisms. In the Predicate Intersection Model, suggested by Meyer (1970), the first stage involves a serial, self-terminating search among

Imaging studies of semantic memory

Current Opinion in Neurology, 2008
The neural basis of semantic memory has not only theoretical interest, but also implications for several neurodegenerative disorders such as Alzheimer's disease and semantic dementia.The main focus of functional imaging studies is to disentangle the contribution of several interacting factors to the landscape of cerebral activation observed in normal ...

From Semantic Memory to Semantic Content

2019
Barsalou (1992), Lobner (2014, 2015) hypothesise that frames form the natural way in which the brain represents concepts and more complicated semantic content built from concepts. An interesting aspect of the hypothesis is that it becomes easy to define stochastic properties of concepts.

Semantic Processing, Semantic Memory, and Recall

1985
Publisher Summary The objective in the current research program is to select a semantic strategy that would (1) facilitate recall in a variety of different tasks, (2) be relatively easy to teach, and (3) be relatively easy to learn and use. The first experiment is designed to compare different semantic processing strategies that might be effective ...

A Semantically Associative Memory

1962
Whereas associative memories have usually been based on the syntax of the contents of cells in the memory (such as on specific bit configurations), a model is proposed in which the associations between entries in the cells are characterized independently of their contents.
