[Certain aspects of laterality research].
One-side dominance, known as morphological and functional asymmetry, in the limbs a human characteristic that is of genetic or of both genetic and environmental origin. There are several aspects investigating laterality in men. Altogether it is possible to distinguish morphological and functional asymmetries. A vast range of testing techniques have been used to assess handedness. Asymmetry in hand use takes two forms: differential hand preference and differential dexterity between the hands. Writing hand and self-report are two of the most popular techniques. Other preference measures include observation of how people use tools and questionnaires. Performance tests assess speed and accuracy in tasks stressing manipulative dexterity. Morphologic asymmetries are not so useful for the investigation of the handedness. This method should only be used in past mortem examinations. The literature on laterality is large, but there are only a few studies in the last years concerning the morphologic asymmetries compared to the studies on functional asymmetries.
