Treatment vs. diagnosis.
Paul Sorum Albany Medical College, Albany, NY E-mail: email@example.com
I want to alert those who read our report last year or heard my presentation in Florida that, after the meeting, Tom Stewart and Claudia Gonzalez-Vallejo redid the analyses entirely. The new version just appeared: Sorum PC, Stewart TR, Mullet E, Gonzalez-Vallejo C, Shim J, Chasseigne G, Munoz Sastre MT, Grenier B. Does choosing a treatment depend on making a diagnosis?

Further Studies of Epistemic Artifacts

For the past year, most of my research effort has concentrated on further analysis of the "epistemic artifacts" used by Michael Faraday in his 1856 research on the optical properties of gold. Readers may recall that most of these are microscope slides prepared by Faraday and carefully cross-indexed to his very thorough lab notes covering the research.
Up to now, most of our efforts have centered on the difficult chemical manipulations needed to replicate these objects - we feel more like chemists sometimes than psychologists! This phase is now drawing to an end (partly as we recognize some realistic limits on what can be done) and our focus is turning to explicit cognitive analysis of the mountain of data we are facing. The "data" includes:
Faraday's own records (now digitized in several formats),
Our photographs of his specimens (about 1/5 have been photographed, but I now have the digital photography down to a routine; perhaps my next London trip will allow completion)
(3) Records from our own replications (narrative accounts, as well as photographs and physical specimens).
How do we analyze this material? We are presently construing this as an extended protocol which manifests a variety of frame-like entities within specific "arenas" that change quite frequently (and often run in parallel). We are using techniques for representing the material based heavily on protocol analysis procedures of a "Carnegie Mellon" sort. Beyond that, we have discussed various quantitative approaches that seem promising, perhaps including Markov models of topic transitions.
Finally, we see the project as inherently Brunswikian in the sense that the task we face is how to adequately model the epistemic environment Faraday constructed and used to formulate conclusions about the topic at hand. For Brunswik, science was something like "ultimate perception." Just so.
I have been ably assisted in part or all of the work by Ryan Mears, Christiane Spitzmueller, Yanlong Sun, Chris Ayala, Neil Berg, and Robert Gibby. Mike Doherty kibbutzes on occasion, and he and I have also collaborated on a few papers (about which, see his newsletter contribution).
Persuasion, Judgment and Learning
Elise Axelrad Weaver, Ph.D. Dept. of Social Science and Policy Studies Worcester Polytechnic Institute e-mail: email@example.com
In the last year, I moved to my new job as an assistant professor at Worcester Polytechnic Institute (www.wpi.edu). I am involved in four projects: First, I am revising an article based on my dissertation, which revisits an old debate regarding psychological reactance and impression management. The new twist is that what is monitored is an index of change in cue weights, rather than self-reported attitudes.
The second project, with Tom Stewart, is a study of the factor structure underlying judgment tasks from the Brunswikian literature, the heuristics and biases literature, and IQ and memory. We find four factors of judgment: IQ/Memory, Probability Manipulation, Learning Probabilistic Associations, and Verbal Reasoning. Three measures of accurate judgment differ from each other in their loadings across these factors, but none of these load on Verbal Reasoning. In contrast, all of the heuristics and biases tasks we measured do load on Verbal Reasoning.
