It is proposed that there is a low-level automatic component of visual scanning in which saccades are triggered probabilistically in time by nonfoveal stimulus features. By ignoring cognitive factors
Visual Fixation Durations and Saccade Amplitudes: Shifting Relationship in a Variety of Conditions
Is there any relationship between visual fixation durations and saccade amplitudes in free exploration of pictures and scenes? In four experiments with naturalistic stimuli, we compared eye movements
Distributions of fixation durations and visual acquisition rates.
In this paper, we investigated fixation durations and distributions of visual acquisition times in two experiments. In the first experiment, we reanalyzed fixation data obtained from previous
ICAT: a computational model for the adaptive control of fixation durations
A new model for the control of fixation durations in saccadic tasks is proposed and it is demonstrated by numerical simulations that the model qualitatively reproduces patterns of mean fixation d duration and fixation duration distributions observed in typical experiments.
Time course of information processing during scene perception: The relationship between saccade amplitude and fixation duration
The present study focuses on two aspects of the time course of visual information processing during the perception of natural scenes. The first aspect is the change of fixation duration and saccade
An Experimental Consideration of Fixation Properties
The experimental results indicate that “fluctuation during fixation (FDF)” which is larger movements than “miniature eye movements” occurred and FDF varies according to the peripherals of fixation points characterized by the size and complexity of the stimulus object.
Distractor effect and saccade amplitudes: Further evidence on different modes of processing in free exploration of visual images
It is shown that retinotopically identical visual events occurring 100 ms after the onset of a fixation have significantly less influence on fixation duration if the amplitude of the previous saccade exceeds the parafoveal range (set on 5° of arc).
Time Course and Hazard Function: A Distributional Analysis of Fixation Duration in Reading
Reading processes affect not only the mean of fixation duration but also its distribution function. This paper introduces a set of hypotheses that link the timing and strength of a reading process to


Is the Duration of an Eye Fixation a Sufficient Criterion Referring to Information Input?
The data suggest that duration of eye fixation alone is not a sufficient criterion for distinguishing among the three possible purposes of single eye fixations, and the distribution of durations must be represented at least by a bimodal vs trimodal curve.
Estimating frequency and size of effects due to experimental manipulations in eye movement research
The Frequency of Effects Analysis is described and its use with data from a study on characteristics of the perceptual span of adult readers is illustrated, indicating that, in one instance, a manipulation which produced a 21 msec increase in fixation duration was actually producing a 151 msec increase.
Effect of the size of a complex display upon visual search.

This investigation is one of a series of studies designed to determine natural search tendencies during visual search tasks and found that search behavior in displays subtending 9° and larger at the eye remained essentially the same.
Statistical Dependency in Visual Scanning
A method to identify statistical dependencies in the positions of eye fixations is developed and applied to eye movement data from subjects who viewed dynamic displays of air traffic and judged
Eye-movement responses to step and pulse-step stimuli.
The experiments demonstrate that the visual system is sometimes able to cancel an eye-movement response to a pulse, on the basis of information contained in the subsequent step, to which it responds instead.
