The Flinders Handedness survey (FLANDERS): a brief measure of skilled hand preference.

Knowing whether an individual prefers the left or right hand for skilled activities is important to researchers in experimental psychology and neuroscience. The current study reports on a new measure of skilled hand preference derived from the Provins and Cunliffe (1972) handedness inventory. Undergraduates (n = 3324) indicated their lateral preference for their hands, feet, eyes and ears. A measure of hand performance and familial handedness was also obtained. Factor analysis identified ten items that loaded on skilled hand preference and these were included in the new FLANDERS questionnaire. Cluster analysis of the new questionnaire revealed three distinct groups (left-, mixed- & right-handed). The new test showed a strong association with other measures of lateral preference and hand performance. Scores on the test were also related to the sex of the respondent and the hand preference of their parents. The FLANDERS provides a measure of skilled hand preference that is easy to administer and understand and should be useful for experimenters wanting to screen for hand preference.
