Neurofeedback training effect is cumulative and tends to not disappear over time as is common with placebos. Placebo effect tends to reach maximum quickly and then fall off. Also, training effects tend to be consistent with localization of function within the brain. Many clinicians will see improvements in areas of function that the child or adult were not expecting. It is common to receive reports of improved performance from independent observers who are unaware of the person's treatment, such as teachers, friends and extended family members. In addition, the initial discoveries of Neurofeedback effectiveness in eliminating seizure activity were made in connection with animal research (Sterman 1976). It is highly unlikely that feline seizure activity was resolved due to the cat's strong belief in Dr. Sterman and his research methods.
