Abstract/OtherAbstract:
|
Visual orienting has typically been characterized using simple displays--for example, displays with a static target placed on a homogeneous background. In the present study, visual orienting was investigated using a dynamic broadband (1/f) noise display that should mimic a more naturalistic setting and that should allow saccadic orienting experiments to be performed with fewer constraints. In Experiment 1, it was shown that the noise movie contains gaze-attracting features that are almost as distinct as the ones measured for (static) real-word scenes. The movie can therefore serve as a strong distractor. In Experiment 2, observers carried out a luminance target search that showed that saccadic amplitude errors were substantially higher (18%) than the ones measured in simple displays. That error is certainly one of the primary factors making gaze-fixation prediction in complex scenes difficult.
