comment How is sample size determined in animal research?
Do you mean 'determine the sample size', not 'draw/estimate the sample size'? Is this question in the context of power analysis?

comment Analysis of parameter estimates from Ratcliff diffusion model
Do I understand correctly that you are planning to fit the diffusion model on a by-participant basis to two data points per participant?

You may also want to check out this paper and the models discussed therein. SWIFT and EZ-Reader are both models of oculomotor control in reading. ncbi.nlm.nih.gov/pmc/articles/PMC2906818

comment Is it possible to distinguish recall and calculation?
@Jeff What exactly do you mean when you say that there is "no computation"? If what we do is break problems down into smaller ones to retrieve their solutions from memory in order to combine them into a single answer, doesn't that constitute "computation" too?

comment Are there known cases where people can write upside down?
Could you elaborate a bit on what exactly happens when you try to write like most of us do? Also: Can you read only upside down?

comment How to analyze reaction times and accuracy together?
Yes, right. I guess one could come up with theoretical situations with non-monotonic SATFs, but a logistic regression of this kind should work fine for most practical purposes, I guess. Thanks.

comment How to analyze reaction times and accuracy together?
As for your suggestion of modeling the logistic regression on RT in each condition. Do you mean regressing response on RT (or some transformation thereof), condition and the interaction thereof? This should capture the differences in the speed-accuracy tradeoff functions, but it seems that such a model would miss differences in RT, if the SATF is the same in both conditions.

I didn't quite understand which of the mentioned approaches is the one proposed by Townsend & Ashby. The one you dubbed L.I.E? :)

Thanks Mike. Why would you prefer the LBA to Ratcliff's diffusion model?
