The main features of this illusion can be quantitatively accounted for in terms of the optics of defocused images and the retinal disparities predicted from blur circles. A residual component of the illusion, however, which was perceived by a majority of subjects, cannot be readily explained by geometrical optics; it apparently reflects a more subtle aspect in the processing of visual images, corresponding to the Anstis\u2013Howard\u2013Rogers stereo-effect, in which local depth configurations can bias global stereopsis. Several novel aspects of that effect are described, based on use of this obstructed-pupil illusion as the evoking stimulus.<\/jats:p>","DOI":"10.1068\/p130547","type":"journal-article","created":{"date-parts":[[2007,1,23]],"date-time":"2007-01-23T10:26:22Z","timestamp":1169547982000},"page":"547-553","source":"Crossref","is-referenced-by-count":0,"title":["A New Random-Dot Stereo Illusion and its Application to the Anstis\u2013Howard\u2013Rogers Effect"],"prefix":"10.1177","volume":"13","author":[{"given":"James Thomas","family":"Enright","sequence":"first","affiliation":[{"name":"Scripps Institution of Oceanography, University of California, La Jolla, CA 92093, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1984,10,1]]},"reference":[{"key":"bibr1-p130547","doi-asserted-by":"publisher","DOI":"10.1016\/0042-6989(78)90189-X"},{"key":"bibr2-p130547","doi-asserted-by":"publisher","DOI":"10.1016\/0042-6989(77)90064-5"},{"key":"bibr3-p130547","doi-asserted-by":"publisher","DOI":"10.1126\/science.6612351"},{"key":"bibr4-p130547","doi-asserted-by":"publisher","DOI":"10.1038\/248363a0"},{"key":"bibr5-p130547","doi-asserted-by":"publisher","DOI":"10.1038\/scientificamerican0376-80"},{"key":"bibr6-p130547","doi-asserted-by":"publisher","DOI":"10.1098\/rspb.1933.0020"},{"key":"bibr7-p130547","doi-asserted-by":"publisher","DOI":"10.1038\/250781a0"}],"container-title":["Perception"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1068\/p130547","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1068\/p130547","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T22:02:21Z","timestamp":1777586541000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1068\/p130547"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1984,10]]},"references-count":7,"journal-issue":{"issue":"5","published-print":{"date-parts":[[1984,10]]}},"alternative-id":["10.1068\/p130547"],"URL":"https:\/\/doi.org\/10.1068\/p130547","relation":{},"ISSN":["0301-0066","1468-4233"],"issn-type":[{"value":"0301-0066","type":"print"},{"value":"1468-4233","type":"electronic"}],"subject":[],"published":{"date-parts":[[1984,10]]}}}
