We give an explicit demonstration, using the rigorous Feynman rules developed in , that the regularized trace Trγ5e −βD/ for the gravitational chiral anomaly expressed as an appropriate quantum mechanical path integral is β-independent up to two-loop level. Identities and diagrammatic notations are developed to facilitate rapid evaluation of graphs given by(More)
Previous work in object categorization has shown that people tend to optimize their allocation of attention to object features, and suggests that attentional optimization may best be explained in terms of cost-benefit tradeoffs. In support of this idea, we found that implementing a cost for accessing information about object features in a category learning(More)
