Some Aspects of Earedness—The Validity and Reliability of Self-Report Items

Abstract

In contrast to the extensive literature on hand, foot, and eye preferences there are only a few studies concerning ear preference. From a review of 27 studies 13 items (Stopwatch, Telephone receiver, Tablecloth, Head movement, Wall, Drawer, Wall phone, Heartbeat, Door, Earphone, Box, Pocket radio, Voice) were identified in the measurements of ear preference. In a series of investigations, these self-report items were validated with respect to individual behavioural measures and test-retest reliabilities were obtained over 1 mo. and 1 yr. for earedness. These data indicate that a questionnaire composed of these items could be a valid and reliable method for the assessment of various forms of ear preference, but there are several differences among the items in validity and reliability.
