Finding the repeating part of a signal
How do people "synchronize" to a periodic signal? In other words, given an oscillating auditory signal, how do people decide where the beat is? Assuming a "beat" divides a signal into equal repeating …

Role of declarative memory in learning skill
In Neil Taatgen's paper on primitive information processing elements (PRIMs) he notes that as a result of saving the used PRIMs in declarative memory (which is fast) as opposed to procedural memory (which … This seems to be making two assumptions:
Procedural memory is slower than declarative memory
Declarative memory is important to building skills
Are either of these assumptions true based on empirical …

Difference between content-addressable memory and associative memory?
Often when I'm reading theoretical neuroscience publications, such as "Towards an integration of deep learning and neuroscience", as well as "Memory and the Computational Brain", theorists often mention … Is the Associative Memory often used in SPA-based models, such as the model used in "Biologically Plausible, Human-Scale Knowledge Representation", the same thing as a content-addressable memories? …

Cognitive Models of learning Working Memory usage
However, these aren't really analogous to how a cognitive systems learns how to use it's working memory. … Are there models of how working memory modules (where a saved value decays over time) can be learned to be optimally leveraged? Either via reinforcement learning or supervised learning? …
