As relaxation progresses, convergent cognitive structures emerge that support the value of focusing, passivity, and openness. In addition, divergent cognitive structures that interfere with relaxation are slowly dissipated. Positive relaxation experiences provide support for convergent structures. As practice continues, the ability to control arousal provides more positive feedback. In addition, the individual becomes more aware of differences between relaxation and tension, both sensorily and cognitively.
Cognitive structures emerge, allowing one to label and articulate changes that accompany relaxation.
Simultaneously, the person abandons irrational or incorrect cognitive structures that interfere with relaxation. The result is a changed set of beliefs about self and the value of activity versus passivity. Although Smith believes that a family resemblance exists between the various relaxation techniques, he also asserts that the techniques differ greatly in demands on the cognitive system. Progressive muscle relaxation is concrete and undemanding, whereas meditative techniques are more demanding. Still, people who begin with a concrete method will most likely progress to more complex cognitive structures.
