Shealy makes reference to several physicians and psychologists who have studied the effect of mood, attitude and belief systems upon illness.
Dr. Caroline Thomas (Johns Hopkins) began a long-term study of Johns Hopkins medical students in 1946 who were regularly followed throughout their lives. Shealy points out that within 20 years she was seeing that some people came in with psychological traits that would create diseases later on in their lives. In retrospect she could see who would tend to develop heart disease, cancer, and who might tend to commit suicide or die in old age of natural causes. Thomas eventually published several books from this study, showing the influence of personality and daily habits as factors in the prediction of heart disease, suicide, cancer, and longevity.

Dr. David Graham (University of Wisconsin), an early trailblazer of psychophysiology (a field of study which focuses on the mind-body interface, and which was the precursor for what we now call psychoneuroimmunology or PNI) was a pioneer in the development of psychosomatic medicine whose research demonstrated a relationship between particular diseases and associated attitudes toward life events.
Hans Eysenck, an influential psychologist in the field of theories of personality, referred to persons who regarded happiness as coming from an internal source, rather than the external circumstances as autonomous.
Abraham Maslow, the father of humanistic psychology, referred to this same concept in terms of self-actualization.Click here for more posts on this blog about Maslow and self-actualization.
