Chung, Moo-Joo. 1996. Perceptual Strategies for the Spatial Expressions Related to `Front/Back` and `Left/Right` Orientation. Studies in Modern Grammatical Theories, 8: 71-89. The main purpose of this paper is to examine the fact that spatial expressions linked with front/back and left/right have both deictic and non-deictic roles according as the specified reference point possesses any intrinsic orientational properties of direction. The results are as follow: First, native speakers of Korean tend to use a deictic strategy (regardless of any kind of dynamic feature) when the referent point does not possess any intrinsic front/back axis. It was observed, however, that a deictic strategy can still be used even when the specified reference point possesses orientational properties, if the uttenance context involves a kind of speaker-centering. Second, the shift between deictic and absolute strategies also occurs with spatial expressions involving `left` and `right`. Speakers of Korean tend to use a deictic strategy for the left/right orientation when the referent has the features of [-intrinsic front/back] and [-intrinsic left/right], whereas an absolute strategy is used for the reference point with intrinsic front/back and left/ right. The shift between these two strategies is confined to a deictic one when the referent object and the speaker are aligned in the same direction.
