“…Experiments 1, 3A, and 3B provided no evidence for a direct role of color in matching (contrary to Green, 1986aGreen, , 1986bGreen, , 1989. Color, however, does play an indirect role in matching figures across images because color can specify figure boundaries, and figures are matched across images.…”

“…Thus, matching does not take place on the basis of color under these stimulus conditions. Experiments (Green, 1986a(Green, , 1986b(Green, , 1989 in which color has been reported to play a role in correspondence matching may have resulted from attentional tracking or cognitive inference on the basis of color, rather than from automatic correspondence matching on the basis of color per se. Here, we controlled for attentional tracking or cognitive inference on the basis of color by embedding the stimuli of interest among stimuli where such strategies would not have been effective.…”

“…Using translational apparent motion as a probe to address questions of form analysis requires that biases introduced by the low-level motion processing system be eliminated before effects of form-based matching can be seen. That is, form-based matching occurs only in translational apparent motion when matching on the basis of the nearest neighbor principle has been controlled for (Green 1986a(Green , 1989Shechter et al, 1988) or when the the low-level motion system's response is attentuated by an interstimulus interval (ISI) of sufficient length (Shiffrar & Freyd, 1993;Ternus, 1926Ternus, /1938. In TAM, however, matching does not primarily take place on the basis of the nearest neighbor principle (Tse et al, 1998).…”

“…Indeed, low spatial frequencies appear to count for more than shape (Green, 1986b;Ramachandran, Ginsburg, & Anstis, 1983), and the most potent factor is found to be spatiotemporal proximity. Although there are examples in which shape or color do play a role in matching (e.g., Green, 1986aGreen, , 1989Shechter, Hochstein, & Hillman, 1988), the effect of these factors is revealed only when the much stronger factor of proximity is carefully controlled for. This tendency to match figures across successive displays on the basis of proximity irrespective of shape or color correspondence has been called the nearest neighbor principle (Ullman, 1978(Ullman, , 1979Wertheimer, 1912Wertheimer, /1961.…”

Transformational apparent motion (TAM) occurs when a figure changes discretely from one configuration to another overlapping configuration. Rather than an abrupt shape change, the initial shape is perceived to transform smoothly into the final shape as if animated by a series of intermediate shapes. We find that TAM follows an analysis of form that takes 80-140 msec. Form analysis can function both at and away from equiluminance and can occur over contours defined by uniform regions as well as outlines. Moreover, the forms analyzed can be 3-D, resulting in motion paths that appear to smoothly project out from or into the stimulus plane. The perceived transformation is generally the one that involves the least change in the shape or location of the initial figure in a 3-D sense. We conclude that perception of TAM follows an analysis of 3-D form that takes ≈100msec. This stage of form analysis may be common to both TAM and second-order motion

“…Stimuli of this type were used by Papathomas, Gorea, and Julesz (1991) to show that color-based motion dominated luminance-based motion under certain conditions, indicating that chromatic signals do playa role in apparent motion. These stimuli can also be adapted for circular motion , forming an extension of Green's stimuli (Green, 1989;Green & Odom, 1986) for multiattribute motion perception. The same type of stimuli was modified and extended for textural grouping studies (Gorea & Papathomas, 1991a, 1991bWerkhoven, Sperling, & Chubb, 1992).…”

This paper presents a unified approach for studying the perception of motion, stereopsis, and staticflow (Glass) patterns. The objective is to address the same issues across these "modalities." To this end, a new class of stimuli and procedures were developed, the key feature of which is the incorporation of a forced-choice competition paradigm into the random-dot stimuli paradigm that has traditionally been used in these modalities. The two competing percepts that are pitted against each other are opposite directions for motion, near/far depth planes for stereopsis, and orthogonal global patterns for Glass patterns. The differences in qualitative predictions for competing hypotheses are generally well pronounced, and the results provide clear evidence for deciding between alternative hypotheses. This approach has been used to confirm that covariance is the preferred metric for eliciting global correlations in all the modalities and to investigate the nature of front-end processes in each modality. It has the potential for neurophysiological studies for both single-cell and neuronal ensemble recording.
