“…In another experiment, Stromeyer (1972) found that the ME weakened or disappeared when a test grating was moved to a different retinal area from the induced area. Results of other experiments also indicate that the ME is retinotopic (Broerse & Grimbeek, 1994;Broerse & O'Shea, 1995;Humphrey, Herbert, Symons, & Kara, 1994;Humphrey, Skowbo, Symons, Herbert, & Grant, 1994; for review, see Humphrey, 1998;, but and Siegel, Allan, & Eissenberg (1992 have presented results suggesting that the ME is spatiotopic. It appears that much of the evidence favors a retinotopic account of the ME, but there is certainly room for more research to decide this issue definitely.…”

“…Although this line ofreasoning seems right-headed insofar as it supports concepts of recalibration and tuning that have been advanced by others (Dodwell & Humphrey, 1990;Held, 1980;Wolfe, 1990), its present formulation in terms ofobject constancy cannot be correct. A great deal of evidence from several laboratories supports the finding that forms that are locally orthogonal in orientation but globally completely unrelatable by the necessary kind of transformation do, nonetheless, produce (local) McCollough-like effects (e.g., Broerse & O'Shea, 1995;Dodwell & O'Shea, 1987;Dodwell & Humphrey, 1990;Emerson et aI., 1985;McCollough, 1994;Yasuda, 1978).…”

“…Given the volume ofevidence favoring an early (and retinotopically local) locus for the McCollough effect (e.g., Broerse & O'Shea, 1995;Humphrey, Goodale, & Gurnsey, 1991;Humphrey, Gurnsey, & Fekete, 1991;Humphrey, Herbert, Symons, & Kara, 1994;Humphrey, Skowbo, Symons, Herbert, & Grant, 1994), such a view seems unsatisfactory. Although a classical conditioning approach does not necessarily have to be identified with global stimulus representation, it does lend itself to the interpretation that the unit of association is the global stimulus.…”

Although there is controversy surrounding the possibility of nonretinotopic adaptation to certain other fairly simple forms (Broerse & Grimbeek, 1994;Humphrey, Herbert, Symons, & Kara, 1994;Siegel, Allan, & Eissenberg, 1992, 1994, most investigators support the view that the effects are primarily due to local form (e.g., local orientation and spatial frequency).…”

Visual aftereffect of texture density contingent on color of frame

An aftereffect of perceived texture density contingent on the color of a surrounding region is reported. In a series of experiments, participants were adapted, with fixation, to stimuli in which the relative density of two achromatic texture regions was perfectly correlated with the color presented in a surrounding region. Following adaptation, the perceived relative density of the two regions was contingent on the color of the surrounding region or of the texture elements themselves. For example, if high density on the left was correlated with a blue surround during adaptation (and high density on the right with a yellow surround), then in order for the left and right textures to appear equal in the assessment phase, denser texture was required on the left in the presence of a blue surround (and denser texture on the right in the context of a yellow surround). Contingent aftereffects were found (1) with black-and-white scatter-dot textures, (2) with luminance-balanced textures, and (3) when the texture elements, rather than the surrounds, were colored during assessment. Effect size was decreased when the elements themselves were colored, but also when spatial subportions of the surround were used for the presentation of color. The effect may be mediated by retinal color spreading (Peppel, 1986)and appears consistent with a local associative account of contingent aftereffects, such as Barlow's (1990) model of modifIable inhibition.After adaptation to a dense texture localized in a specific region of the visual field, a visual aftereffect develops such that textures presented in that region will appear much less dense than when presented in another, nonadapted region (Anstis, 1974;Durgin & Proffitt, 1991). In the present paper I show that this aftereffect of texture density (not to be confused with spatial frequency) can be made contingent on color information presented in a spatially distinct (and otherwise untextured) region of the display. Previously, aftereffects both of motion (Potts & Harris, 1975) and ofcolor (Siegel, Allan, & Eissenberg, 1992) have been made contingent on information presented in a surrounding region orframe (color and texture in the former case and lightness in the latter). However, no framecontingent aftereffects have been reported in which the apparent spatial distribution ofluminance contrast is altered. Thus, the present study represents a unique demonstration of an aftereffect of spatial pattern contingent on information in the surround.It is often possible to make the perceptual distortion of one visual dimension contingent on the presence of another quite different dimension.

“…McCollough (1965), for example, attributed CCAEs to color adaptation oforientation-specific edge detectors, but did not specify that these detectors were sensitive only to edges defined by luminance contrast. More recently, Broerse and O'Shea (1995;see also Broerse, Shaw, Dodwell, & Muir, 1994) have also argued for the importance of edges in the induction of CCAEs and concluded that CCAEs are present only at edges. Broerse and O'Shea did not mention, however, that the edges must be defined by luminance contrast to be effective, and that edges defined only by color contrast are ineffective.…”

In the typical induction of the orientation-contingent color aftereffect (CCAE), the stimuli are composed of elements that differ in both color and luminance. Three experiments are reported that show that chromatic contrast between stimulus elements is insufficient for the induction of the orientation-CCAE and that luminance contrast is necessary. These experiments expand on previous research concerned with the role of luminance contrast in the induction of orientation-CCAEsby eliminating alternative explanations.The orientation-contingent color aftereffect (CCAE) typically is induced by alternating two complementarily colored and orthogonally oriented grids every few seconds for several minutes (McCollough, 1965). For example, a grid constructed of black-and-green horizontal bars might be alternated with a grid constructed ofblackand-red vertical bars. Following such induction, complementary color aftereffects contingent on grid orientation are noted-black-and-white assessment grids appear colored. In this example, the white space between the black horizontal bars appears pink and the white space between the black vertical bars appears green.The grids used in the induction of the orientation-CCAE are usually composed of chromatic and achromatic (black) bars that differ in luminance. A few studies have examined the role of the luminance contrast' between the chromatic and achromatic bars in the induction ofthe orientation-CCAE. Ellis (1977) and Mikaelian (1980) systematically varied luminance contrast by increasing the luminance of the achromatic bars from black to various shades of gray. They reported that the size of the orientation-CCAE decreased with decreasing luminance contrast and concluded that isoluminant grids were ineffective in inducing an orientation-CCAE. Allan, Siegel, Toppan, and Lockhead (1991) also reported that induction with grids composed of gray and colored isoluminant bars did not result in an orientation-CCAE. These studies are in agreement with Stromeyer's (1978) often-cited conclusion, based on unpublished data, that luminance contrast is necessary for the induction of the orientation-CCAE. ' Although the existing data suggest that luminance contrast is necessary for the induction ofthe orientation-CCAE, an examination of the published experiments reveals that the absence of the orientation-CCAE after isoluminant induction might be attributable to variables other than the luminance contrast of the induction grids. The three experiments reported in the present paper explore this possibility. GENERAL METHOD SubjectsA total of 59 subjects participated in the three experiments. The subjects had no previous experience in contingent aftereffect tasks, and each subject participated in only one of the three experiments. All but 2 of the subjects were students enrolled in introductory psychology at McMastcr University who received course credit for their participation. The remaining 2 subjects (Experiment 2) were 5th year engineering students who volunteered.
