A Theory of Attention and Decision-Making in Multi-Attribute and Multi-Object Perceptual Judgements

Grant number: DP110103406 | Funding period: 2011 - 2014

Abstract

The human brain is an efficient biological computation device for rapidly translating perception into action. This project will develop and test a mathematical model of the processes of visual selective attention and perceptual decision-making. These processes are at the heart of the brain's ability to carry out this translation in a fast and accurate way.
