judgment analysis results change in a repeat study of the same practitioners following the community- wide intervention this fall.
In the fourth project, Tom Stewart and I are collecting data related to the question of whether vicarious functioning is an example of implicit learning, and whether explicit reportable knowledge aids probability learning.

We continued to capitalize in our research a lot on the symmetry principles of the lens model. We have applied these principles to different research domains with great success. A chapter titled: "Brunswik-symmetry a key concept for successful psychological research just appeared as a book chapter (unfortunately in German only). The reference is: Wittmann,W.W.

In a related study, we have done a judgment analysis study of the factors leading to prescription of antibiotics in a group of 95 practitioners in Denver who are taking part in a controlled trial of an intervention to reduce antibiotic prescribing. Once again, there is great variation in the strategies and the practitioners appear to be poorly calibrated with regard to antibiotic prescription (in comparison with guidelines from the CDC). We will see if the

from international conferences in PowerPoint to get a flavor of the beauty of Brunswik symmetry and how to capitalize on it in terms of prediction and explanation.
