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.
