Deriving Cognitive Strategies from Fixations during Visual Search in Scenes
Monica S. Castelhano · 2023
Research has established that scene context improves performance in visual search affecting attentional guidance by providing predictions and expectations about where target objects are likely to be located. Here, the reliability of scene context is manipulated, by using an Exploitation/Exploration framework. The results showed that not only is context important, but that it depended on its reliability, showing a dynamic application over time. Eye movement patterns reflect this dynamic application of high-level information. This framework will allow us to define and detect different cognitive strategies as well as the switch between them, signaling a change in prioritization and a change in the influence of context.
