About this questionnaire
The Edinburgh Handedness Inventory (Oldfield, 1971) is the standard way to measure handedness in research, from brain imaging to motor studies. This is the four-item short form by Jaimie Veale (2014), which keeps the items that best separate left- and right-handers.
For each action or object, choose the hand you prefer to use.
Scoring: each answer counts from −100 (always left) to +100 (always right), and your laterality quotient (LQ) is their average. −61 or lower is left-handed, +61 or higher is right-handed, and anything in between is mixed-handed (Veale, 2014).
Before you start
For reflection, not diagnosis. This is a self-report questionnaire. It cannot diagnose any condition, and it is not a basis for hiring, admission or any other decision about a person.
Private by default. Everything runs in your browser. Your answers are not saved or sent anywhere unless you choose, before starting, to share them anonymously for site statistics.
Provided as is. A personal project, free and with no warranty. Not connected to any institution I work with.
