Could the outcome of Neurofeedback training be due to a placebo effect?
No, and here are the reasons why: 1. The effects of EEG biofeedback training are highly specific to electrode placement and to training frequency band 2. Training protocols exist which can commonly elicit effects opposite to those desired. 3. The effects of training with one protocol can be reversed with another. 4. The effect of the training is cumulative, rather than fading with time, as is common with placebos. 5. If EEG biofeedback were to be explained in terms of placebo phenomena, it would be a first time that placebos are dose-dependent. 6. Training effects are in line with expectations from neuropsychology regarding localization of function. 7. Populations can be moved to levels of performance which exceed those of nave populations 8. The effects of the training often lie outside the range of expectations for spontaneous recovery or placebo effects, not only with respect to the magnitude of the changes elicited but also with respect to the consistency with which they are produc
