Real-world search D.J.Aks < in progress> |
| Visual search is a pervasive and critical skill to functioning in the real world. A number of examples are shown below. Studying search in real world settings offers many opportunties for determining effective search strategies, and gaining a better understanding of process(es) that drive effective search. Given the impressive pattern recognition and search skills inherent to human vision, formal study of human search behavior in realistic settings is likely to offer guidance to optimizing (human as well as automated) search strategies. |
Key goal to all of these studies is to learn about optimal
sampling processes. Approach: Examine individual differences in eye-tracking behavior to understand effective search patterns. Pattern of search in most capable 'searchers' may reveal important insights into optimal process for sampling the environment. |

Context & implicit
memory effects |
||||||
| Previous research shows that search is more efficient when the context (i.e., item arrangement or background information) is fixed over time. Understanding those conditions in which (implicit) memory, together with environmental information, facilitates search can offer a powerful tool for predicting the presence of targeted information in a variety of settings. | |||||||
