Apparent size of circles in the Delboeuf configuration wasjudged under variation of their diameters and compared to that ofcircle singletons of equivalent diameter. The primary purpose of thestudy was to investigate the effect of judgment order on the perceivedsize, i.e. starting with either inner or outer circle. In addition, wecompared the measured strength of the illusion as obtained by twodifferent methods - category rating and magnitude estimation. We foundthat the circle judged first had an assimilative effect on the apparentsize of the subsequently judged circle, with the amount of the effectbeing contingent on diameter ratio and diameter difference of theconstituent circles. Moreover, assimilation of the inner circle wasmore pronounced than that of the outer circle. The judgment-ordereffect may be accounted for by attentional mechanisms: if the outercircle is judged first, spatial span of attention is large, so that theinner circle falls in the span. Conversely, if the inner circle isjudged initially, spatial span of attention is too small to take up theouter circle. The amount of illusion was greater when judged usingmagnitude estimation than category rating, conceivably due to a coarserinternal mapping at the latter procedure.

Size contrast was studied in the Ebbinghaus illusion with inducing circles (ICs) that were either larger or smaller than the central test circle (TC). Four ICs formed either squares or diamonds; or in a mixed-size condition four large ICs alternated with four small ICs. Figures were presented on printed cards and studied as a function of IC-TC distance, or displayed on a computer screen at various angles of orientation. A separate circle, presented left or right of an Ebbinghaus figure and varying in size, served for simultaneous comparision. A general overestimation was found for figures presented right from the comparison circle. Size contrast diminished with increasing IC-TC distance for small ICs, but increased for large ICs. Square arrays had stronger inducing effects than diamonds with small ICs, but weaker with large ICs: the mixed-size condition resulted in a small underestimation. Furthermore, size contrast depended systematically on the angle of IC-array orientation. The Ebbinghaus illusion thus obeys structural factors in a rather peculiar way, suggesting the necessity of a compound model of size contrast.

In order to clarify the differences between the visual and the auditory memories and the interference effect between them, a paired presentation method was developed. In this method, the subject under the experimental condition memorized two independent sequences of random digits, which were presented simultaneously digit by digit, the digits of the one sequence being presented visually and the digits of the other auditorily. After the presentation, subjects were asked to recall first either the visual or the auditory digit sequence, and then the other sequence. The subject under the control condition, on the other hand, memorized one sequence of random digits which were presented either visually or auditorily, and after recalling them memorized another sequence of random digits presented in the other modality. The results can be summarized as follows. (1) Under the experimental as well as under the control conditions, the recency effect appeared in the auditory memory task, but it did not in the visual memory task. (2) The performance for visual by presented digits under the experimental condition was lower than that under the control condition, whereas the performance for auditorily presented digits under the former was equal to that under the latter. The results presented might suggest that: (1) there are independent visual and auditory memories in the short-term memory; and (2) the memorizing of the auditory materials interferes with the memorizing of the visual one, but the latter does not interfere with the former.
