The overall purpose of the research done under the Air Force Grant was to test a model of bias in the judgment of spatial location. The model holds that the representation of locations is not itself biased, but that it is the process of estimation that leads to bias. The process we argue is one of combining category and fine grain information about location e.g., for any item in a circle, polar coordinates as specific locations and quadrant as category location. In the early years of the grant we made an initial test of the model in a set of four experiments that appeared in Psychological Review Huttenlocher, Hedges, and Duncan, 1991. Categories and particulars Prototype effects in estimating spatial location. Psychological Review, 98, 352-376. In the later years we have carried out a set of experiments to test the model much more extensively. The work has not been submitted for publication, but is in preparation.
