Functional influences on visual search fixation duration JF - Journal of Eye Movement Research JA - JEMR VL - 10 IS - 1 SE - Articles DO - 10.16910/10.1.5 UR - https://bop.unibe.ch/JEMR/article/view/2956 SP - AB - <p class="jemr05Abstract">Real time simulation of visual search behavior can occur only if the control of fixation durations is sufficiently understood.  Visual search studies have typically confounded pre- and post-saccadic influences on fixation duration.  In the present study, pre- and post-saccadic influences on fixation durations were compared by considering saccade direction. Novel use of a gaze-contingent moving obstructer paradigm also addressed relative contributions of both influences to total fixation duration.   As a function of saccade direction, pre-saccadic fixation durations exhibited a different pattern from post-saccadic fixation durations.  Post-saccadic fixations were also more strongly influenced by peripheral obstruction than pre-saccadic fixation durations. This suggests that post-saccadic influences may contribute more to fixation durations than pre-saccadic influences. Together, the results demonstrate that it is insufficient to model the control of visual search fixation durations without consideration of pre- and post-saccadic influences.</p><p> </p> ER -
