Spatial Regularities
We frequently search for objects during our everyday lives, and the context we find ourselves in helps predict where the object we are searching for will be located. We have investigated what information we extract and remember as we perform visual search tasks, particularly what we learn by performing a search over and over again in the same context (contextual cueing), and what we learn as we perform a particular search (rapid resumption). Our work has shown that our learning in both of these cases is restricted by computational feasibility, preventing us from using remembering and using all of the available information, yet still being sensitive to the regularities present in the displays.Papers
