The impact of changing information on perceptual decision-making

When we make decisions, we are often faced with complex, changing information. Any reasonable decision-making process should be able to adjust to and integrate new information, yet little is known about how this is done. Most past decision research has been devoted to understanding stationary decisions where a choice is made on the basis of fixed, unchanging information. In this talk, I will discuss a series of experiments examining perceptual decision-making in tasks with non-stationary (changing) evidence. I will also discuss how piecewise sequential sampling models can be used to infer evidence accumulation properties before and after changed information in these tasks.
