1.1. Is Intermittent Updating of Probability Estimates Due to Motor Costs?
Date: Author: Britt Anderson
A decade ago an excellent article with an educational reminder of some forgotten history was published by Gallistel and colleagues. The main method was to observe the trial by trial reports of participants estimating the Bernoulli parameter while observing a sequence of "coin flips" with intermittent changes in the underlying, true, parameter. The main conclusion was that participants were not doing trial-by-trial updating, because their reports showed a step-and-hold pattern of updating. What Julia Schirmeister investigated was a possible motor confound, identified by Forsgren in their rebuttal.
1.2. Caroline Simpson and Pruning Cascade Correlation Networks
Date: Author: Britt Anderson
For some time now Hanbin and I have been interested in the cascade correlation (pdf) neural network architecture. The two of us played with it some using the code that its inventor, Scott Fahlman, made available on line in Lisp (and again, isn't it amazing to use a programming language that you can run out of the box forty years after it was written).
1.3. Cognitive Modeling of Complex Behavior - The Lorentz Center
Date: Author: Britt Anderson
How Best to Model a Complex Behavior? I recently had the chance to attend a workshop devoted to reflecting on exactly that problem. It was a wonderful experience. Not just because the topic was interesting, and my fellow attendees were smart and fun people to learn from, but also because the venue fostered an environment that allowed one to exit from the day to day pre-occupations and focus in a sustained way.
