In the previous experiment upon the so-called "Divided distance illusion", an amount of illusion was measured as a magnitude of over-estimation of the distance between two outer lines under the experimental situation where the length of outer lines was held constant, and the length of inner lines was varied. The present experiment was conducted to investigate the interactive effect between the outer lines and the inner ones by varing the length of outer lines. The length of the outer lines (lo) and the length of the inner lines (li) were both 10mm, 20mm, and 40mm. And there were five experimental conditions by combining li's and lo's The li's and lo's combined in each condition were as follows: (Condition A) 10 and 10, (Condition B) 20 and 20, (Condition C) 40 and 40, (Condition D) 20 and 10, (ConditionE) 20 and 40. Experimental results in five conditions were grouped into three groups. These groups were as follows : (GroupI) A, B, and C ; (GroupII) A, B, and D ; (GroupIII) B, C, and E. And within each group, a ststistical analysis through the method of analysis of variance was done, and thereafter t-tests using error variance terms as denominators were applied to test significance of differences about the amounts of illusion between any pairs of conditions within a group. The results thus obtained were summarized as follows: (1) In Group I, Condition B was smaller than Condition A and Condition C with highly statistical significance where the distances between inner lines(d) were both 40 mm and 50 mm. (2) In Group II, the statistically significant differences were found between Condition D and Condition A where d was 40 mm; and between Condition D and Condition B where d was 50 mm. But amounts of illusion in Condition D varied in a similar way as Condition A and Condition B did. (3) In Group III, Condition E was smaller than Condition C with highly statistical significance where d's were both 40 mm and 50 mm, but there was no statistical significance between Condition E and Condition B. And Condition E was smaller than both Condition B and Condition C where d was 20 mm.
