What's a Psychological Model?

• A Psychological (or Cognitive) Model is a model of cognitive (or thought) processes.
• They're typically models of human thought, but sometimes of animal thought.
• There are box and arrow diagrams (like Broadbent) but these aren't computational models.
• There are loads of computational models for thought processes such as associative memory, language parsing, language comprehension, object recognition, visual attention and hundreds (maybe thousands) of other tasks.
• What would a computational Psychological Model look like?
• We have a cognitive model of Probability Matching in a Two-Choice Task Based on Stochastic Control of Learning in Neural Cell-Assemblies
• Roughly there are a series of inputs and outputs. Given a particular set of inputs, the model should generate the right outputs.
• This paper is particularly cool because it does it with neurons.
