The Johnson O'Connor Research Foundation is a nonprofit scientific research and educational organization with two primary commitments: to study human abilities and to provide people with a knowledge of their aptitudes that will help them in making decisions about school and work. Since 1922, hundreds of thousands of people have used our aptitude testing service to learn more about themselves and to derive more satisfaction from their lives.


Aptitudes are natural talents, special abilities for doing, or learning to do, certain kinds of things. Manual dexterity, musical ability, spatial visualization, and memory for numbers are examples of such aptitudes. In a comprehensive battery of tests available only through the Foundation, these and many other aptitudes are measured. These measured traits are highly stable over long-term periods.

The Foundation is working with Dr. Rex Jung of the University of New Mexico to recruit twins for a major study of heritability, aptitude, and brain imaging. If you are a twin, or if you know twins (or other multiple births) who might be interested in participating, we'd love to hear from you. It is essential that both twins (or at least two of any other multiple) participate. Full details can be obtained from Dr. Jung and his associates at or 505-272-7036.
