This is an interactive version of the Open Hemispheric Brain Dominance Scale, a measure of left and right brain cognitive style.

Introduction: The human brain is split down the middle, dividing it into two halves with a small connection at the base. In the late 1970s that idea individuals would have a preference for one hemisphere like they do for handedness became popular. This idea was promoted a lot as an educational tool, that the different hemispheres learned in different ways and so teaching should be tailored towards a persons preference. The theory is completely bogus, however. There is no evidence for individual preference in hemisphere and the usefulness of dividing people on the basis of the traits ascribed to the hemispheres is not clear.

The Open Hemispheric Brain Dominance Scale was developed by selecting items that correlated with five other published left-brain right-brain tests.

Procedure: The inventory consists of 24 items that must be rated on how much you agree with them on a five point scale where 1=Disagree, 3=Neutral and 5=Agree. It should take most people 3 to 5 minutes to complete.

Participation: You use of this assessment should be for educational or entertainment purposes only. This is not psychological advice of any kind. Additionally, your responses to this questionnaire will be anonymously saved and possibly used for research or otherwise distributed.
