People learning to emit alpha waves through feedback from an electroencephalograph is an example of __________.

A) systematic desensitization
B) biofeedback training
C) counterconditioning
D) regularization

Biofeedback training involves using instruments to provide information about physiological processes, such as brainwaves, and then learning to control these processes through mental and physical techniques. Learning to emit alpha waves through feedback from an electroencephalograph is an example of biofeedback training. Systematic desensitization and counterconditioning are both forms of behavioral therapy, and regularization is not a relevant term in this context.
