Asymmetrical control of fixation durations in scene viewing
In two experiments we investigated the control of fixation durations in naturalistic scene viewing. Empirical evidence from the scene onset delay paradigm and numerical simulations of such data with the CRISP model [Psychological Review 117 (2010) 382-405] have suggested that processing related difficulties may lead to prolonged fixation durations. Here, we ask whether processing related facili...
متن کاملCRISP: a computational model of fixation durations in scene viewing.
Eye-movement control during scene viewing can be represented as a series of individual decisions about where and when to move the eyes. While substantial behavioral and computational research has been devoted to investigating the placement of fixations in scenes, relatively little is known about the mechanisms that control fixation durations. Here, we propose a computational model (CRISP) that ...
متن کاملEye movement control during scene viewing: immediate effects of scene luminance on fixation durations.
Recent research on eye movements during scene viewing has primarily focused on where the eyes fixate. But eye fixations also differ in their durations. Here we investigated whether fixation durations in scene viewing are under the direct and immediate control of the current visual input. Subjects freely viewed photographs of scenes in preparation for a later memory test while their eye movement...
متن کاملProgramming of saccades to double-step targets in scene viewing: A test of assumptions present in the CRISP model
Several computational models explaining fixation durations in scene viewing (Nuthmann, Smith, Engbert, & Henderson, 2010) and in reading (Engbert, Nuthmann, Richter, & Kliegl, 2005; Reichle, Pollatsek, Fisher, & Rayner, 1998) assume that saccade programming is completed in two stages: an initial, labile stage that is subject to cancellation and an subsequent, non-labile stage in which the progr...
متن کاملThe Influence of Content Meaningfulness on Eye Movements across Tasks: Evidence from Scene Viewing and Reading
The present study investigated the influence of content meaningfulness on eye-movement control in reading and scene viewing. Texts and scenes were manipulated to make them uninterpretable, and then eye-movements in reading and scene-viewing were compared to those in pseudo-reading and pseudo-scene viewing. Fixation durations and saccade amplitudes were greater for pseudo-stimuli. The effect of ...
