Crowding degrades saccadic search performance

摘要: The identity of a target is more difficult to acquire when it surrounded by distracters. purpose the present experiments was investigate implications this crowding phenomenon for performance and eye movements in real-life task as search with movements. participants searched one dimensional strip. Above below strip additional elements were added. In three conditions, similarity these mask varied. spatial extent known increase target-mask [Nazir, T. A. (1992).

One condition did not contain masks. visibility experiment, we firstly validated manipulation. subsequently found that increasing times up 76% longer. Eye also affected. number fixations fixation increased saccade amplitude decreased crowding. We conclude order understand (everyday) tasks require active exploration visual scene, should be taken into account.
