      Agreed. Would you also distinguish between ‘theory’ and ‘theoretical franework’? I tend to think in terms of this progression of specificity: theoretical framework —> theory —> model.

      Yea that seems a reasonable spectrum. I think they all still have in common that there is some predictive power, but with increasing precision & decreasing generality.

      Don't forget the different between (computational) models and implementations of models too! 😅

      It might be useful to specify the degree of precision we are seeking to attain and the scope of the predictions we intend to formulate. Then we can perhaps determine whether this is viable at the level of 'theory'

      I have no problem with others having different definitions of theory to me TBH. Variety in methods and variety in definitions is a good thing.

      This is a fundamental distinction that, unfortunately, is too often disregarded and one critical reason why, in my view, many psychologists misunderstand the complexities of building computational models

      I'm not sure I fully understand the difference. Is implementation here the actual coding langauge/software (which I guess would be similar to Marr's levels)? Is it still common for psychologists to use these kinds of models tied to specific code?

      Grace, I'm really sorry I have a migraine (been 3 weeks now), so I am going to link to something I wrote and get back to prepping a talk: http://dx.doi.org/10.1016/j.cogsys.2013.05.001 … When I feel better/have less on my plate I'll come back — also I am sure Esther and others can do a great job. Sorry!

          Also just to be clear the answer is in what I linked to but I obviously would rather talk it out over Twitter since I know it's useful in and of itself. 🌺 I promise to return when I get some headspace/spoons back!

          Olivia is the expert here but plainly put, the main difference is that the implementation (code) includes many instructions that are alien to the theory itself and that are required for the program to work.

          A Bayesian conception of the distinction might be model = structure, implementation = structure + params + data.

          If by parameters you mean their specific values , not the ontology, then I agree 😊

          Does that capture that an implementation might contain like graphs and stuff that are by no means important to the theory or model at all?
