The ABC in #BayesInPsych: Approximating likelihoods in simulation models

(This post was co-authored with Brandon Turner). Sharon Bertsch McGrayne’s 2012 book, The Theory That Would Not Die: How Bayes’ Rule Cracked the Enigma Code, Hunted Down Russian Submarines, and Emerged Triumphant from Two Centuries of Controversy, traces the difficulties that statisticians and empirical researchers alike have had in embracing Bayesian methods.

Stitching time onto a tree: joining models of accuracy with response times to understand cognition

“Time is what we want most, but what, alas! we use worst.” —William Penn There are many dimensions of human behavior. Consider a typical recognition memory task in which a participant is given a list of words to remember. A little while later, suppose this participant is shown the word “bear” and asked whether it […]
