“…Whereas Thelin (1927) andvan Waters (1934) found results consistent with Duncker's suggestion, Carr and Hardy (1920) and Wagenaar et al (1984) found inconclusive results, and Mack et al (1975) found the reverse effect. Brosgole (1966Brosgole ( , 1968 challenged both Duncker's (1929Duncker's ( / 1938) frame-of-reference theory and the subsumed separationof-systems concept.…”

“…They can also be inferred from experiments demonstrating separable motion in depth and expansion and contraction aftereffects from the same stimulation (Beverley & Regan, 1979). Wagenaar et al (1984) suggested that induced movement, at least at near-threshold motion of the inducing stimulus, can be entirely explained in terms of low-level sensory processing. Although it is worthwhile to seek the lowest level of explanation, it must be in accordance with empirical findings.…”

“…Form of the inducing stimulus. This can vary in size from a spot often the size of the induced stimulus, itself also a spot (e.g., Carr & Hardy, 1920;Duncker, 1929Duncker, /1938Mack, Fisher, & Fendrich, 1975;Thelin, 1927;Wagenaar et al, 1984), to a pattern filling virtually all the subject's visual field (e.g., Post, 1986;Post & Heckman, 1986). Variations of the frame stimulus involve filling the frame with pattern (e.g., Bacon, Gordon, & Schulman, 1982;Wallach & Becklen, 1983).…”

“…Brosgole's (1966Brosgole's ( , 1968 theory does not require that the induced stimulus be surrounded by the inducing stimulus. Enclosure is not always necessary for induced movement when the inducing stimulus undergoes overall displacement (Oppenheimer, 1935;Wagenaar et al, 1984;Possible Distinction Between Induced Movement With and Without Overall Displacement of the Inducing Stimulus section).…”

Induced movement, illusory movement in a stationary stimulus resulting from adjoining movement, has received steady experimental investigation over the last 70 years or so. It is observed under different viewing conditions in a wide variety of displays that differ considerably in overall size and in form of inducing and induced stimuli. Explanations have been diverse, some being based on relations within the display and others invoking mediation by other aspects of the observer's perception. Probably, no one explanation can account for all forms of induced movement. Current knowledge about induced movement may have important implications for visual perception of object morion. Among possibly important factors is size of display, which can vary from two small spots (e.g., Carr & Hardy, 1920) to displays occupying most of the observer's visual field (e.g., Post, 1986).A second major purpose of this overview is to examine explanations for induced movement (Explanations section). Duncker's (1929Duncker's ( /1938 findings have had an important influence here, although many of his suggestions have subsequently been shown to require at least some modification. For example, his theory I thank J. Morss for reading an earlier version of this article, J. Ravey for translation, and two anonymous referees for helpful suggestions.
