Abstract

The study presents the results of the examination of handedness in 2 groups of school children aged 9 to 10 years, living in Central Slovakia, and differing only as to the region of birth and growing up. One region is highly polluted by industrial pollutants (such as As, Mn, Pb,Cd, NOx, SOx and vinylchloride): Here lives the ''Affected group'' (AG, n=83). The ''Control Group'' (CG, n=80) comes from the other regionwhich is relatively non-contaminated. We measured lateral asymmetry of handedness with regard to the characteristics stability (tremor), speed (tapping), accuracy (dotting), and sensorimotor coordination (tracing). Tile size of the lateral difference was expressed as a Laterality Score (LS = right minus left) for every child and task. It was foundthat children from the polluted region show significantly greater lateral differences, especially for tremor and tracing (no. of deviations); on the other hand, bilateral asymmetry was lower for the number of correct hits in the dotting task.
