The Negative After-Effect of the Perception of a Surface Slanted in the Third Dimension

The growth of the equidistance tendency over time

“…This effect was shown by both the SL and LS conditions. This finding is consistent with those of Gibson (1950) and Bergman and Gibson (1959) in which the perceived slant of textured surfaces were investigated, and with Gogel's (1965) interpretation of the results elf these studies. This finding (or any of the others) is not consistent with data supporting the (Clark, 1953).…”

“…His data suggest, if one assumes the equivalence of a texture and relative size gradient, that a critical duration exists beyond which further increases in duration would result in an increase rather than a decrease in the perceived relative depth of objects. The studies of Harker (1962), Gogel (1954), Bergman and Gibson (1959), and Gibson (1950) are compatible with the hypothesis that the relationship is monotonic.…”

“…Bergman and Gibson (1959) and Gibson (1950) reported that without altering the physical angle of tilt, the perceived slant of a surface gradually decreased over time. Gogel (1954) demonstrated that the perceived depth interval between two objects differing in relative size decreases over time.…”

“…Gogel (1954) demonstrated that the perceived depth interval between two objects differing in relative size decreases over time. Assuming that a texture gradient such as existed in the Bergman and Gibson (1959) and Gibson (1950) experiments constituted a relative size gradient, Gogel (1965) proposed that ET was the factor altering perceived slant in the texture gradient experiments.…”

Perceptual Artifacts and Phenomena: Gibson's Role in the 20th Century

“…Crooks, 1938), but finally roundly rejected (G ibson, 1951, 1971b) central aspects of Gestalt psychology. Gibson also tinkered with phenomena in other research areas, such as adaptation effects (Gibson, 1933(Gibson, , 1937Bergman &. Gibson, 1959), learning theory (Gibson &: Hudson, 1935), memory rCSC<lrch (Gibson &: Raffel, 1938), and even social psychology (G ibson, 195Oa;see also Gibson, 1967;Reed, 1988).…”
