Abstract: The importance of careful systematic research in the development of therapeutic models is evident. The present study is an exploration of an increasingly popular sensory-based therapeutic model, known as Neurolinguistic Programming (NLP). The study provided a research foundation for NLP and reviewed the current terminology and therapeutic interventions from 14 NLP publications (e.g., Dilts, Grinder, Bandler, and DeLozier, 1980). Five theoretical assumptions were proposed for NLP. These were : (1) NLP is a single- domain theory; (2) Experiences may be internally represented via at least five sensory channels; (3) Sensory representational channels may be directed either internally or externally; (4) There are consistent relationships between a person's external, observable behavior and his internal sensory processing; and, (5) Communication between individuals is enhanced if they emphasize the same sensory channel. The present study examined the relationship between one behavioral measure (sensory predicate usage) and internal imaging. Data was obtained from forty-five female college students during ten imaging tasks (visual, auditory, kinesthetic, combined, -- pleasant and unpleasant -- , earliest memory, accomplishment). The ten experimental tasks primarily involved subject- generated images based upon the Personal Imagery Questionnaire (Baer and McSweeny, 1976). The obtained results suggest a systematic relationship between sensory predicate usage and internal imaging. In addition to collecting descriptive data regarding sensory predicates, the present study tested whether sensory predicate usage might be considered as a situational variable. Past research and publications of NLP have almost exclusively considered sensory predicates as a trait characteristic reflecting an individual's cognitive typology or primary representational system (i.e., visualizer, audile, kinesthete). It was found that most individuals predominantly use kinesthetic sensory predicates, which was consistent with past research on NLP (e.g., Gumm, Walker, and Day, 1982). Concurrently, it was found that individuals are easily able to shift their use of predicates according to the context or task demands. Implications for future research and theoretical development of Neurolinguistic Programming are discussed.
