Perceptual organization and the judgment of brightness.
The perceived brightness of a gray patch depends on the surrounding context. For example, a medium-gray patch appears darker when placed on a bright background and brighter when placed on a dark background. Models to explain these effects are usually based on simple low-level mechanisms. A new set of brightness illusions cannot be explained by such models. In these illusions, the brightness per...
متن کاملIndividual Opinions-Based Judgment Aggregation Procedures
Judgment aggregation is a recent formal discipline that studies how to aggregate individual judgments on logically connected propositions to form collective decisions on the same propositions. Despite the apparent simplicity of the problem, the aggregation of individual judgments can result in an inconsistent outcome. This seriously troubles this research field. Expert panels, legal courts, boa...
متن کاملIndividual moral judgment and cultural ideologies.
Moral judgment cannot be reduced to cultural ideology, or vice versa. But when each construct is measured separately, then combined, the product predicts powerfully to moral thinking. In Study 1, 2 churches (N = 96) were selected for their differences on religious ideology, political identity, and moral judgment. By combining these 3 variables, a multiple correlation of .79 predicted to members...
متن کاملReconstruction of Convex Bodies from Brightness Functions
Algorithms are given for reconstructing an approximation to an unknown convex body from finitely many values of its brightness function, the function giving the volumes of its projections onto hyperplanes. One of these algorithms constructs a convex polytope with less than a prescribed number of facets, while the others do not restrict the number of facets. Convergence of the polytopes to the b...
متن کاملCausal judgment from contingency information: relation between subjective reports and individual tendencies in judgment.
In two experiments, participants made causal judgments from contingency information for problems with different objective contingencies. After the judgment task, the participants reported how their judgments had changed following each type of contingency information. Some reported idiosyncratic tendencies--in other words, tendencies contrary to those expected under associative-learning and norm...
