The Reliability of Single Subject Statistics for Biofeedback Studies.
Bremner, Frederick J.; And Others
To test the usefulness of single subject statistical designs for biofeedback, three experiments were conducted comparing biofeedback to meditation, and to a compound stimulus recognition task. In a statistical sense, this experimental design is best described as one experiment with two replications. The apparatus for each of the three experiments was the same: stimulus presentation and process control, data collection and storage, and data reduction and statistical analysis. The procedure for the three experiments was identical, except for counter balancing the order of treatments. Each of the three college subjects was given six weeks of meditation training, three weeks of biofeedback training, and one session of training with the compound stimulus (visual, auditory and tactile). Twenty seconds of electroencephalogram data were sampled from each of the three treatments. Analysis of variance confirms the hypothesis that biofeedback is significantly different from the other treatments and that the interaction between biofeedback and stimuli is also significant. The paper states that, in particular, the statistical difference between biofeedback and the other two treatments of this experiment is strong evidence to refute claims that biofeedback does not do anything. It is felt that the single subject approach described in this paper is very useful for biofeedback studies. Numerous tables and graphs are included. (PN)
