The Edinburgh Handedness Inventory is a measurement scale used to assess the dominance of a person's right or left hand in everyday activities, sometime referred to as laterality. The inventory can be used by an observer assessing the person, or by a person self-reporting hand use. The latter method tends to be less reliable due to a person over-attributing tasks to the dominant hand.
The Edinburgh Handedness Inventory was published in 1971 by R.C. Oldfield and has been used in various scientific studies as well as popular literature.
