The purpose of this study is to clarify the reference domains of demonstrative pronouns from reclining postures. In everyday conversation in Japan, we use the three different demonstrative pronouns, "KORE", "SORE", and "ARE". The differences between the usage of these three pronouns indicate that the space surrounding a person can be divided into three reference domains. The experiments were carried out in a large experimental room. Subjects were located lying on one's back on the bed. Subjects were indicated the electric bulb, then were asked to KORE/SORE/ARE. The results are summarized as below; 1)The reference domain of "ARE" encloses the domain of "SORE", which encloses the domain of "KORE". 2)The reference domain of "KORE" encloses from head to knee, and has relation to the motion area of the arm. 3)The reference domains of demonstrative pronouns from reclining postures are different from the reference domains of demonstrative pronouns from standing postures.
