It was found that the fixation position was displaced from that expected on the basis of target geometry when the illusion was seen, and that the amount of displacement was proportional to the strength of the illusion (defined as the amount by which the length of one part of the composite figure must be altered so that both ‘arrows’ appear to be of equal length). The effect did not occur when the illusion was destroyed by presenting the parts of the Muller-Lyer figure separately. The selection of the desired position on the retina for the image of a fixated target is thus not solely a function of the geometry of the target. Perceived or phenomenological aspects of the target also exert an effect in the selection of image position.","PeriodicalId":78927,"journal":{"name":"Optica acta","volume":"14 2","pages":"119-26"},"PeriodicalIF":0.0,"publicationDate":"1967-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/713818026","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17114780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The special case of the straight line horopter is re-examined and the theoretical general formula obtained. The implications of these theoretical results are discussed and the relevant findings of an extensive investigation of the horopter in asymmetric convergence are presented. The variation of the empirical H (the Hering-Hillebrand deviation) with the angle of asymmetric convergence is compared to the variation of H with observation distance. Whilst evidence is insufficient to refute the “stability of corresponding points” hypothesis, these results suggest a tendency of the visual apparatus to maintain a constant individual shape of the horopter.","PeriodicalId":78927,"journal":{"name":"Optica acta","volume":"12 3","pages":"305-15"},"PeriodicalIF":0.0,"publicationDate":"1965-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/713817940","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"16908179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
