The principle of stereopsis, that crossed disparity causes a convex perception and uncrossed disparity a concave one, has for a long time been considered to depend on a very rigid neural mechanism not affected by experience. Experiments are reported here which show that this relationship between disparity and perceived depth can be reversed by experience. An observer wore a pair of left-right reversing spectacles continuously for nine days. The spectacles also reversed the relation between the direction of perceived depth and the direction of binocular depth cues, ie disparity and vergence. For a period starting two days before wearing the spectacles and continuing until seventy-nine days after their removal the observer was examined with a haploscope and an electrooculograph. All the stereoscopic experiments were carried out without spectacles in order to examine some aftereffects of wearing spectacles. For the stereograms with linear contours not only the adaptive reversal of the relation between disparity and perceived depth, but also some abnormal depth perceptions and long-lasting aftereffects were found. For Julesz's random-dot stereograms, however, in which contours can be seen only after binocular combination, no adaptive change or reversal occurred. These results suggest that the process of stereopsis consists of two concurrent subprocesses.

Recent study of [Sugita, Y. (1996) Global plasticity in adult visual cortex following reversal of visual input. Nature, 380, 523-526.] demonstrated that prism adaptation to reversed retinal input generates the transfer of neuronal activities in monkey V1 to the opposite visual cortex. This raises the question if perceptual learning on one side of the visual field can transfer to the other side. We tested this in using the Gabor lateral masking paradigm. Before adaptation, long-range interaction was induced vertically on one side (i.e., the right) of the visual field with training (perceptual l

Three experiments were performed to investigate the effect of prolonged exposure to leftright reversed vision on visually induced sensation of self-motion (vection). The vision reversal was attained by means of prism goggles. Human subjects wore such goggles continuously for about 8 days (Experiment 1), 5 hours (Experiment 2), or 14 days (Experiment 3). The subjective self-motion was produced with a laterally moving random pattern. The subjects wearing the goggles were asked to report the onset of perceived self-motion and its direction and to give magnitude estimates of the perceived speeds o The vision reversal was attained by means of prism goggles. Human subjects wore such goggles continuously for about 8 days (Experiment 1), 5 hours (Experiment 2), or 14 days (Experiment 3). The subjective self-motion was produced with a laterally moving random pattern. The subjects wearing the goggles were asked to report the onset of perceived self-motion and its direction and to give magnitude estimates of the perceived speeds of that motion and of the motion of the pattern. Such vection tests were also carried out under normal but restricted vision before and after the exposure period. The results showed that the exposure to the reversed vision does not change the direction of vection. This is inconsistent with the earlier findings of Oman, Bock, and Huang (1980). It was also found that reversed vection, i. e., the motion in direction the same as that of perceived stimulus motion can occur under normal vision even before wearing reversing goggles. 収録刊行物 Ｊａｐａｎｅｓｅ　Ｐｓｙｃｈｏｌｏｇｉｃａｌ　Ｒｅｓｅａｒｃｈ Ｊａｐａｎｅｓｅ　Ｐｓｙｃｈｏｌｏｇｉｃａｌ　Ｒｅｓｅａｒｃｈ 30 (1), 25-32, 1988 公益社団法人 日本心理学会 Tweet キーワード vection self-motion optokinetic stimulation visual-vestibular interaction reversed vision prism adaptation 詳細情報 詳細情報について CRID 1390001204594396544 NII論文ID 130001474914 DOI 10.4992/psycholres1954.30.25 ISSN 14685884 00215368 Web Site https://www.jstage.jst.go.jp/article/psycholres1954/30/1/30_1_25/_pdf データソース種別 JaLC Crossref CiNii Articles OpenAIRE 抄録ライセンスフラグ 使用不可 書き出し RefWorksに書き出し EndNoteに書き出し Mendeleyに書き出し RDFで書き出し Refer/BibIXで表示 RISで表示 BibTeXで表示 TSVで表示 CSVで表示 JSON-LDで表示 問題の指摘 論文情報の修正 その他 ページトップへ 現時点での人物検索の対象は、科研費報告書やresearchmapの記載に基づき研究者番号が推定された研究者等約30万人です。 ※詳しい説明はこちら
