“…Three eye-movement parameters-the duration, number, and location of eye fixations-care intrinsically involved in visual perception. Systematic correlations of these three eye-movement parameters with changes introduced into the shapes of patterns shown to human Ss have been previously established (Gould, 1967;Gould & Schaffer, 1967). These experiments concluded that the duration of an eye fixation on a pattern correlates with the length of time needed to process it; that whether or not a pattern is fixated foveally depends upon the "similarity" of that pattern to a standard pattern; and that refixation of a particular pattern indicates the need to obtain more information about it.…”

Fig. 1. Schematic of stimulus. Stimuli always contained a center standard pattern surrounded by eight other patterns of asterisks, some of which matched the standard (called targets) and some of which differed from the standard (called nontargets).Second, the effects on eye-movement parameters of the size of the matrix from which patterns were generated was assessed. Patterns were generated from 4 by 4, 6 by 6, 8 by 8, and 10 by 10 matrices. The larger the matrix size, the larger the average number of elements in a pattern. The results of this study showed clearly-perhaps surprisingly-that pattern discrimination was not affected by these variations in matrix size.Third, the effect on eye-movement parameters of the variations in the number of elements in a pattern of a particular matrix size was evaluated. The results of the study showed that variations in the number of elements in target patterns of a particular matrix size affected eye movement parameters differently than did variations in the number of elements in nontarget patterns of the same matrix size. A target pattern was nearly always fixated foveally, whereas the probability of looking directly at a nontarget pattern depended upon its "similarity" to the standard pattern. Duration of fixation on a pattern, however, was determined both by variations in target patterns and by variations in nontarget patterns.Fourth, an attempt was made to identify the features or variations in patterns, in addition to those specifically manipulated in this experiment, that most affect human pattern discrimination. There presently exists no universal psychophysics of pattern perception. That is, although the three physical variables of intensity, wavelength, and purity account well for the perception of homogeneous visual fields, the physical variables that account for the perception of patterned visual fields have not been satisfactorily identified. This is true even though 1~200

Eye movements were monitored during the performance of triple conjunction search tasks. Stimuli varied in color, shape, and orientation. Across trials, the target was either present or absent, and displays consisted of 6, 12, or 24 stimuli. Stimulus discriminability was manipulated for the shape dimension, with half of the participants seeing displays of Es and Fs (low-discriminability [LD] condition) and half seeing displays of Cs and Ts (high-discriminability [HD] condition). Participants in both conditions performed two search tasks. In the single-feature (SF) task, the target stimulus shared one feature with each of the distractors, whereas in the two-feature (TF) task, it shared two features with each distractor. An examination of saccadic endpoints revealed that participants were more likely to fixate on distractor stimuli sharing color (SF task) or color and shape (TF task) with the target. This was a robust finding, being observed across participants, saccades of different amplitudes and sequential position, and following short and long latencies to move. The extent to which participants made use of shape information increased with discriminability.
