Experimental, clinical, and personal observations give some support to the notions that: (1) intensive live training with anxious subjects is required in order to demonstrate that perspective relaxation has physiological effects; (2) physiological, cognitive, and behavioral symptoms of anxiety are separable and may respond differentially to various forms of treatment; (3) various relaxation techniques produce different subjective experiences; and (4) experiences of cognitive passivity are associated with higher levels of EEG alpha. Results of several case studies indicate that progressive relaxation and/or biofeedback are useful with physiological tension symptoms, and cognitively-oriented techniques, such as meditation, are appropriate treatment for cognitive anxiety symptoms.
