Difference of parapsychology to scientific psychology?

Scientific pscyhology and parapsychology share many traits. Scientific psychology is the practice of inquiring into the nature of human emotions, reactions and perceptions in controlled laboratory studies. Parapsychology is the the practice of inquiring into specific exceptional experiences relating to mind-oriented communications and effects.

Both use qualitative and quantitative research methods. Both study effects which are often so subtle that they require statiscal analysis to assure the effects in fact exist. And the outcomes of the experiments seem to be sensitive to the beliefs or emotional states not only of subjects but also of the experimenters. This is known as "Experimenter Effect".

Both publish their results in peer-reviewed journals recognized as authoritative in their respective disciplines. Practitioners in both disciplines are members of scientific organizations recognized and accredited by the American Association for the Advancement of Science (AAAS).
