| Research Abstract |
The phenomenon of illusory conjunctions of letters, or letter migration, has been investigated with alphabetic writing systems. In the present work the phenomenon was studied with a logographic system (Japanese Kanji). Two briefly exposed complex "source" characters, each made up by two components or "radicals", were followed by a probe character which in the critical conditions was a blend of two components, one from each of the two source characters. The task of the subject was to decide whether the probe was one of the two source characters. Subjects often erroneously report having seen the probe before, in some cases producing a "radical migration" response. This study investigates the effects on radical migration of figural factors (arrangement and position of the components in the two source characters) and of a "higher level" factor, namely the potential frequency of radical-joints and the phonological similarity between the probe and one of the two source characters. According to the results of the present study, radical migration in Kanji recognition can be taken to depend on the action of both figural and of lexical factors.
