Human visual search follows a suboptimal Bayesian strategy revealed by a spatiotemporal computational model and experiment

Abstract

Yunhui Zhou and Yuguo Yu propose a continuous-time eye movement model capable of predicting both eye fixation location and duration. Their model accounts for saccadic inaccuracy/bias and memory constraints and, applied to real data, shows that humans may use an eye movement strategy that balances task performance and costs when searching for a target.
