Current models of communication fear and avoidance are analyzed (i.e., genetic, social and interactional). A new model is proposed, linking language, imagery, emotion, and behavior to complex neurological systems in the brain. Evidence for the model is taken from several related fields of study, especially neurolinguistics, neuropsychology, neurophysiology, and neuropharmacology. Implications for the understanding, measurement, and efficacy of treatment interventions designed to reduce communication fear are advanced. (Contains 77 references and a figure.) (Author/RS)
