Why is it difficult to test the efficacy of biofeedback using experimental techniques?
A.
It is difficult to devise a control treatment that replicates biofeedback.
B.
Biofeedback cannot be subjected to testing because it is pseudoscience.
C.
The principles of biofeedback are not entirely understood.
D.
Biofeedback is not concerned with any scientific subject
I think that the best answer would be A. because biofeedback changes your brain waves which induce certain areas to create extra chemicals therefore stimulating you brain. where as medication is the chemicals so there fore there would be no constant to compare against.
