The Psychology of Neurofeedback : Clinical Intervention even if Applied Placebo

The 33 pages here are basically arguing that neurofeedback is all placebo. If your doctor or therapist recommend this, ask for their interpretation of research proving it works. Bet they have none in hand.

ABSTRACT

Advocates of neurofeedback make bold claims concerning brain regulation, treatment of disorders, and mental health.

Decades of research and thousands of peer-reviewed publications

support neurofeedback using electroencephalography (EEG-nf); yet, few experiments isolate the act of receiving feedback from a specific brain

signal as a necessary precursor to obtain the purported benefits.

Moreover, while psychosocial parameters including participant

motivation and expectation, rather than neurobiological substrates,

seem to fuel clinical improvement across a wide range of disorders,

for-profit clinics continue to sprout across North America and Europe.

Here we highlight the tenuous evidence supporting EEG-nf and sketch out the weaknesses of this approach. We challenge classic arguments often articulated by proponents of EEG-nf and underscore how psychologists and mental health professionals stand to benefit from studying the ubiquitous placebo influences that likely drive these treatment outcomes.
