ERIKSSON, E. S. Field effects and two-dimensional form perception. Scand.J. Psychol., 1967, 8, 218-242.-The perceived shape of circles and ellipses as influenced by surrounding figures has been studied under monocular conditions. The data show systematic field effects of a complex character. An effort was made to apply the potential theory in Newtonian physics to the perception. The conclusion drawn was that the force function which monotonically decreases with distance is a valid model for the description of simultaneous effects, but is too simple a model for an adequate description of the data concerning after-effects. A model based on a more complex function was tested, which gave a better fit. The existence of methodological artefacts concerning the identity matching method due to after-effects is indicated. 1.0061 0.977 0.9920 Single circle 0.9715Conditions. The conditions were the same as in the first experiment except that the circular aperture was increased to 13.64".Results. Table two shows the means of eight productions per condition. The difference between the shortest and the largest contour distance is significant, p < .027 (one-tailed), as tested by the Walsh test. Conclusion.The visual field is characterized by attraction. The change in size of the reference frame does not change the monotonically decreasing relationship between contour distance and form change. Thus we seem justified in interpreting the obtained effects as mainly determined by the inducing circles in relation to the standard. Experiment 3stimulus? E.g. will an inducing line yield the effect of attraction? Problem. Will the same outcome be obtained if we use another configuration as inducingConditions. The aperture was 13.64". The test circle was 0.93~-Above and below the test circle was placed a horizontal straight line 0.93' x 0.037'. The contour distance was varied in six steps. Otherwise the conditions were as in Experiment 2. Table 3 gives the means of eight productions per condition. The difference between the first and sixth conditions is significant, p < .023 (two-tailed). Results. Conclusion.The visual field is characterized by both attraction and repulsion. This outcome seems to be at variance with the earlier obtained results. A reasonably explanation Scand. J . Psychol., Val. 8,1967 ExpePiment 7Problem. Does the matched shape of a test circle change when the form of the reference frame is changed?Hypothesis. According to the above argument the matched shape of the test circle will increase (i.e. the vertical/horizontal axis ratio will increase) when the proximal form of the reference frame decreases. Conditions.The reference frame subtended a visual angle of 21.4~ and was presented either with a form of 0.90 or a form of 1.0. The test circle was 2.86".Results.

“…The concept of lateral inhibition plays an important role in some recent approaches which are devoted primarily to an analysis of Mach band (Ratliff, 1965) and the figural after-effects (Ganz, 1965(Ganz, , 1966a.

“…In the present study similar after-effects were obtained both with fixation and with free inspection conditions. There is at present very little evidence to show when-if ever-fixation is a necessary condition for FAEs (Malhotra, 1966). Gibson (1933) and Gibson et al (1937) found that the FAE produced by inspection of a curved line is stronger without than with fixation.…”

Apparent Properties of Inspection Figures as Determiners of Figural After‐effects

Figural after‐effects (FAE) were studied using the Hering, the Ehrenstein, and the Orbisson illusion, patterns in two ways. In one condition, the total pattern was used as inspection figure (IF), and that part of the pattern in which the illusion normally appears, as test figure (TF). The resulting FAE was in a direction opposite to that of the illusion. In the second condition, the illusion producing part of the total pattern served as IF, and the illusion suffering part as TF. This produced an after‐effect, the direction of which was the same as that of the illusion.
