Project:  Estimation of computational models of the impact of attention on simple choice using Julia
Disciplines:  Computer Science, Computation and Neural Systems
Mentor:  Antonio Rangel, Bing Prof. of Neuroscience & Economics, (HSS), arangel@caltech.edu
Background:  Cognitive neuroscientists have developed computational models of how visual fixations influence the computation and comparison of the values of options at the time of choice. These models can provide highly accurate predictions about the effect of attention on choices and reaction times, once a small number of free parameters is fit using out-of-sample data. Fitting these parameters is computationally very costly and takes too long with existing software, which has impeded research in this area.
Description:  This project involves building a tool box for estimating the free parameters of the attentional Drift Diffusion Model of simple choice using the Julia programming language. The project will also involve building a simple website to document how to use the toolbox.
