INVENTORY-DERIVED TASK HANDEDNESS PREFERENCES OF 9 PROFESSIONS AND THEIR ASSOCIATIONS WITH SELF-REPORT GLOBAL HANDEDNESS PREFERENCES

The handedness preference (laterality) of 1,196 professionals grouped in nine professions previously reported using self-reported global han dedness and scores on a modified Edinburgh Handedness Inventory was fu rther defined by evaluating the association between profession and the 10 manual tasks of the inventory. The previously reported ranking of professions in order of increasing righthandedness of laterality score arose from the handedness of specific inventory tasks. A similar asso ciation was found for self-reported global handedness. The evidence co ntinues to support the hypothesis of an association between handedness preference and specific aptitudes or skills in this sample of profess ional persons.
