[Some aspects of sensorial asymmetries].

The present review shows the variability assessing sensoric asymmetries. There are preference and performance tests. Sensoric asymmetries are strongest and most manifest for eyedness (eye preference and performance), descending through earedness and other less known asymmetries. A vast range of testing techniques have been used to assess eyedness. Sighting dominance and self-report are two of the most popular techniques. Other preference measures include observation of how people use tools and questionnaires. Performance test assess speed and accuracy in tasks stressing sensoric dexterity. Although questionnaires are generally thought to be reliable and valid instruments, there is a disagreement as to the nature, the number and weighting of the items to be included.
