Japanese two-kanji compound words (Jukugo : e.g.,侵略"invasion") have two sets of neighbors : rear neighbors that share the same kanji in the front (e.g.,侵入"intrusion") ; and front neighbors that share the same kanji at the rear of the Jukugo (e.g.,侵略"strategy"). A neighbor of higher frequency is represented as a "+ neighbor", whereas a neighbor of a lower frequency is a "- neighbor". We investigated the neighborhood frequency effect of rear neighbors (R+/R-) and front neighbors (F+/F-) in Jukugo identification by using a progressive demasking task, where the pattern mask degraded the visibility of a presented Jukugo. The position of the pattern mask was either of four types : front, rear, whole, and no position. The results indicated that in the whole and the front mask conditions, Jukugo in the F-R+ condition yielded longer reaction times than those in the other conditions. In the rear mask condition however, a difference in reaction times for the F-R+ and F+R+ conditions was not observed. The results are discussed in terms of two activation processes : a local activation of a rear neighbor of higher frequency and a global activation of a front neighbor.
