Chances and challenges for an active visual search perspective

  • Sven Ohl (a1) and Martin Rolfs (a1)

Abstract

Using fixations as the fundamental unit of visual search is an appealing gear change in a paradigm that has long dominated attention research. To truly inform theories of search, however, additional challenges must be faced, including (1) an empirically motivated definition of fixation in the presence of fixational saccades and (2) the biases and limitations of transsaccadic perception and memory.
