This theory predicts that if the cues are not interpreted as evidence of interposition, no intervening surface need be postulated, hence no subjective contours would be seen. This prediction, however, is difficult to test because observers normally interpret the cues as interposition evidence and normally see the subjective contours. Tests are reported on a patient with visual agnosia who is unable to make the usual interposition interpretations and unable to see subjective contours, but has normal ability to interpret standard visual illusions, stereograms, and in particular, stereogram versions of the standard subjective contour figures, which elicit to him strong subjective edges in depth (corresponding to the subjective contours viewed in the monocular versions of the figures).<\/jats:p>","DOI":"10.1068\/p120491","type":"journal-article","created":{"date-parts":[[2007,1,23]],"date-time":"2007-01-23T10:25:26Z","timestamp":1169547926000},"page":"491-500","source":"Crossref","is-referenced-by-count":7,"title":["Evidence Relating Subjective Contours and Interpretations Involving Interposition"],"prefix":"10.1177","volume":"12","author":[{"given":"Kent A","family":"Stevens","sequence":"first","affiliation":[{"name":"The Artificial Intelligence Laboratory, Massachusetts Institute of Technology, 545 Technology Square, Cambridge, MA 02139, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1983,8,1]]},"reference":[{"key":"bibr1-p120491","doi-asserted-by":"publisher","DOI":"10.1038\/newbio245256a0"},{"key":"bibr2-p120491","doi-asserted-by":"publisher","DOI":"10.1038\/257582a0"},{"key":"bibr3-p120491","doi-asserted-by":"publisher","DOI":"10.2307\/1422047"},{"key":"bibr4-p120491","doi-asserted-by":"publisher","DOI":"10.2466\/pms.1974.38.3c.1047"},{"key":"bibr5-p120491","doi-asserted-by":"publisher","DOI":"10.2307\/1421648"},{"key":"bibr6-p120491","doi-asserted-by":"publisher","DOI":"10.1037\/h0027435"},{"key":"bibr7-p120491","doi-asserted-by":"publisher","DOI":"10.1037\/h0032940"},{"key":"bibr8-p120491","doi-asserted-by":"publisher","DOI":"10.3758\/BF03333155"},{"key":"bibr9-p120491","doi-asserted-by":"publisher","DOI":"10.2307\/1421323"},{"key":"bibr10-p120491","doi-asserted-by":"publisher","DOI":"10.1068\/p040349"},{"key":"bibr11-p120491","doi-asserted-by":"publisher","DOI":"10.1038\/257219a0"},{"key":"bibr12-p120491","doi-asserted-by":"publisher","DOI":"10.1038\/223578a0"},{"key":"bibr13-p120491","doi-asserted-by":"publisher","DOI":"10.1038\/238051a0"},{"key":"bibr14-p120491","doi-asserted-by":"publisher","DOI":"10.3758\/BF03199279"},{"key":"bibr15-p120491","volume-title":"Physiological Optics","volume":"3","author":"von Helmholtz H","year":"1909","edition":"3"},{"key":"bibr16-p120491","doi-asserted-by":"publisher","DOI":"10.1068\/p040145"},{"key":"bibr17-p120491","first-page":"93","volume":"1","author":"Kanizsa G","year":"1974","journal-title":"Italian Journal of Psychology"},{"key":"bibr18-p120491","doi-asserted-by":"publisher","DOI":"10.1038\/scientificamerican0476-48"},{"key":"bibr19-p120491","first-page":"107","volume":"2","author":"Kennedy J M","year":"1975","journal-title":"Italian Journal of Psychology"},{"key":"bibr20-p120491","volume-title":"Vision and Artifact","author":"Kennedy J M","year":"1976"},{"key":"bibr21-p120491","doi-asserted-by":"publisher","DOI":"10.1068\/p050387"},{"key":"bibr22-p120491","doi-asserted-by":"publisher","DOI":"10.1016\/0042-6989(67)90091-0"},{"key":"bibr23-p120491","doi-asserted-by":"publisher","DOI":"10.1098\/rstb.1976.0090"},{"key":"bibr24-p120491","doi-asserted-by":"publisher","DOI":"10.1068\/p080665"},{"key":"bibr25-p120491","doi-asserted-by":"publisher","DOI":"10.1126\/science.150.3694.348"},{"key":"bibr26-p120491","doi-asserted-by":"publisher","DOI":"10.1016\/S0010-9452(78)80062-8"}],"container-title":["Perception"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1068\/p120491","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1068\/p120491","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,30]],"date-time":"2026-04-30T22:01:49Z","timestamp":1777586509000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1068\/p120491"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1983,8]]},"references-count":26,"journal-issue":{"issue":"4","published-print":{"date-parts":[[1983,8]]}},"alternative-id":["10.1068\/p120491"],"URL":"https:\/\/doi.org\/10.1068\/p120491","relation":{},"ISSN":["0301-0066","1468-4233"],"issn-type":[{"value":"0301-0066","type":"print"},{"value":"1468-4233","type":"electronic"}],"subject":[],"published":{"date-parts":[[1983,8]]}}}
