Reviewing all the newsletters online, I see that our group has only contributed to it 3 times, the last time in 1999, but we have never stopped conducting lens model studies over the last 20 years.
In terms of a lens model paradigm, we appear to be fixed at the place where Brunswik (1945) left off (see the 1956 book, pages 26-29, Experiment D), but this simple paradigm has been employed in contexts ranging from personnel hiring to judged intelligence and personality, burglars' and police assessments of potential burglary targets, and human physical attractiveness.
Our last three published Brunswikian articles have concentrated on how different groups of key players judge building aesthetics. Studies in Environment and Behavior (2001) and Journal of Architectural and Planning Research (2002) examine how architects and laypersons use different objective building cues (fenestration, cladding, height, shape, etc.) to arrive at different aesthetic conclusions. It has long been known that architects judge buildings differently from the rest of us, but these studies begin to elucidate exactly how and why that happens, beginning with objective cues, and including the observer's intermediate-level assessments such as the building's judged complexity, coherence, friendliness, etc. A similar

The architecture studies seemed to catch the media eye, and were summarized in the national Canadian university newspaper University Affairs, the UK popular science journal NewScientist, and a few other places.

Further work is continuing on the discovery of target preferences by a clustering methodology based on the lens model. This methodology has been demonstrated to outperform other clustering methods on synthetic data sets. At this point, it is being modified to take into account the distribution of features in the natural environment.
This work has been presented at various engineering conferences, such as PerMIS 2002 and IEEE SMC, 2002. The work presented at last
