Ka. Provins, THE SPECIFICITY OF MOTOR SKILL AND MANUAL ASYMMETRY - A REVIEW OF THEEVIDENCE AND ITS IMPLICATIONS, Journal of motor behavior, 29(2), 1997, pp. 183-192
Results of investigations on gaining control of limb movements are rev
iewed, and their contribution to understanding the development of manu
al asymmetries is discussed in relation to the discrimination and prog
ramming of appropriate neuromuscular resources. An examination of the
relevant evidence on number and types of manual asymmetries recorded p
rovides strong grounds for concluding that where asymmetries occur, th
ey simply represent a further example of the well-documented activity-
specific nature of motor skills and of the extremely lengthy periods o
f learning or experience needed for their acquisition and perfection.
This specificity of motor skill and manual asymmetry also readily acco
unts for most of the discrepancy usually reported between assessments
of hand preference and performance differences between hands, because
these alternative measures of handedness have rarely employed the same
range or variety of tasks.
