Effects of wedge degradation on the magnitude of the Ponzo illusion
Abstract This research represents an attempt to test empirically three different theoretical explanations for the classic Ponzo illusion: perspective theory, lateral inhibition theory, and assimilation-contrast theory. Under conditions of tachistoscopic presentation (250 msec), 24 male and 24 female...

Under conditions of tachistoscopic presentation (250 msec), 24 male and 24 female undergraduate students were shown the full-wedge Ponzo figure and two degradations, each with either apical or distal line position. Differences in magnitude and direction of illusion among the figures revealed equivocal findings. In accounting for the Ponzo illusion, the results question the adequacy of each theoretical formulation.

Effects of wedge degradation on the magnitude of the Ponzo illusion |
| abstract |
Abstract This research represents an attempt to test empirically three different theoretical explanations for the classic Ponzo illusion: perspective theory, lateral inhibition theory, and assimilation-contrast theory. Under conditions of tachistoscopic presentation (250 msec), 24 male and 24 female undergraduate students were shown the full-wedge Ponzo figure and two degradations, each with either apical or distal line position. Differences in magnitude and direction of illusion among the figures revealed equivocal findings. In accounting for the Ponzo illusion, the results question the adequacy of each theoretical formulation. The weight of the evidence, however, shows greater support for the assimilation-contrast notion. © The psychonomic soceity, inc 1980 |

Under conditions of tachistoscopic presentation (250 msec), 24 male and 24 female undergraduate students were shown the full-wedge Ponzo figure and two degradations, each with either apical or distal line position. Differences in magnitude and direction of illusion among the figures revealed equivocal findings. In accounting for the Ponzo illusion, the results question the adequacy of each theoretical formulation. The weight of the evidence, however, shows greater support for the assimilation-contrast notion.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Lateral Inhibition</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Perspective Theory</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Distal Position</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Apical Position</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Standard Line</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Pollack, Robert H.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Malatesta, Victor J.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Bulletin of the Psychonomic Society</subfield><subfield code="d">Springer-Verlag, 1973</subfield><subfield code="g">15(1980), 6 vom: Juni, Seite 371-374</subfield><subfield code="w">(DE-627)SPR037022717</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:15</subfield><subfield code="g">year:1980</subfield><subfield code="g">number:6</subfield><subfield code="g">month:06</subfield><subfield code="g">pages:371-374</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://dx.doi.org/10.3758/BF03334561</subfield><subfield code="z">lizenzpflichtig</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_SPRINGER</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">15</subfield><subfield code="j">1980</subfield><subfield code="e">6</subfield><subfield code="c">06</subfield><subfield code="h">371-374</subfield></datafield></record></collection>
