“…First of all, consistent with prior findings (Groner et al, 2008;Loschky et al, 2005;Mannan et al, 1995), we found that across all three experiments, fixation durations were lengthened when scenes were band-pass filtered for spatial frequencies. More important, because the filtered scene information was presented during the saccade prior to the critical fixation and could not be predicted in advance, we can infer that the duration of the critical fixation was influenced by processing of the filtered scene information that occurred during the critical fixation.…”

“…Moreover, the difference between the high-pass and low-pass conditions in the present paradigm demonstrates that individual fixation durations were indeed determined by a direct-control mechanism that is sensitive to the scene spatial frequency content in the scene. These findings replicate the results of Loschky et al (2005), where fixation durations were lengthened when information in the periphery was occasionally blurred, and also complement earlier demonstrations of direct control of fixation durations during scene viewing, such as direct influences on fixation durations as a result of scene masking (Henderson & Pierce, 2008;Henderson & Smith, 2009;Luke et al, 2013) and also due to the task relevance of scene information .…”

“…For example, it has been shown that restricting or degrading the availability of stimulus information has an effect on fixation durations (Groner, Groner & von Mühlenen, 2008;Loftus, 1985;Loschky, McConkie, Yang & Miller, 2005;Mannan, Ruddock & Wooding, 1995;Parkhurst, Culurciello & Niebur, 2000). More specifically, when spatial frequency information is filtered from scenes (e.g., using a band-pass filter), fixation durations tend to increase.…”

“…The work by Loschky et al (2005) suggests that it is indeed the case that individual fixations are lengthened when scenes are spatial frequency filtered. Loschky et al introduced a paradigm where, for occasional fixations during scene viewing, the area in the visual periphery was low-pass spatial frequency filtered.…”

The present study employed a saccade-contingent change paradigm to investigate the effect of spatial frequency filtering on fixation durations during scene viewing. Subjects viewed grayscale scenes while encoding them for a later memory test. During randomly chosen saccades, the scene was replaced with an alternate version that remained throughout the critical fixation that followed. In Experiment 1, during the critical fixation, the scene could be changed to high-pass and low-pass spatial frequency filtered versions. Under both conditions, fixation durations increased, and the low-pass condition produced a greater effect than the high-pass condition. In subsequent experiments, we manipulated the familiarity of scene information during the critical fixation by flipping the filtered scenes upside down or horizontally. Under these conditions, we observed lengthening of fixation durations but no difference between the high-pass and low-pass conditions, suggesting that the filtering effect is related to the mismatch between information extracted within the critical fixation and the ongoing scene representation in memory. We also conducted control experiments that tested the effect of changes to scene orientation (Experiment 2a) and the addition of color to a grayscale scene (Experiment 2b). Fixation distribution analysis suggested two effects on the distribution fixation durations: a fast-acting effect that was sensitive to all transsaccadic changes tested and a later effect in the tail of the distribution that was likely tied to the processing of scene information. These findings are discussed in the context of theories of oculomotor control during scene viewing.
