Biofeedback training with a learning disabled child.

Biofeedback training was used to increase a learning disabled child's ability to control his breathing patterns. The procedure was most effective when the child was permitted to explore freely the correlations between his respiratory movements and feedback from the apparatus. Probe trials showed that increased external and self-directed control over the direction and volume of breathing was achieved. Results were discussed in terms of the relationship between biofeedback technology and learning and behavior problems.
