Drift-Diffusion Models

A cognitive model that describes decision making as a process of evidence accumulation.

How does the framework work
Often used to explain response times and accuracy in two-choice tasks.

Programming language: R
A model for investigating repsonse times and the speed-accuracy tradeoff (SAT) by taking mean response time, response time variance, and accuracy of repsonse and transforming them into information quality, response conservativeness, and nondecision time. Thus, it quantifies performance on an SAT task in a manner that scores can be compared between participants.
