In psychotherapy, the client constantly checks or tries to explicate his or her feelings, which produces different words for feelings. The process of explicating feelings may also result in changes in the feelings themselves. This "checking out" of feelings is called "referring to" the feelings. Referring to the feeling and explicating the feeling are essential for feelings to embark on the change process. In this article, we discuss the process of referring to feelings in psychotherapy. Using Carl Rogers's and Eugene Gendlin's theories, we propose a process of "referencing." The referencing process involves not only the client's referring to feelings but also the "happening together" of the client and therapist in explication. The exploration of the referencing process will, hopefully, contribute to the sophistication of how the feeling process occurs in interaction, which is a central issue in humanistic psychology.
