STABILITY OF EXTREME SELECTIONS OF CHILDREN IN EXPRESSIONS OF ACTIVATION - SEARCHING FOR A DOMINANT SYSTEM OF AUTONOMOUS RESPONSES

This work presents the results of a study with two extreme groups of c hildren. Measurements were taken three times - eight and twelve months apart. While the group marked as EG manifests an increased activity o f the cardiovascular system prior and after a sensorymotor load, the P IG group has relatively low values but it consistently responds with h igh electrodermal activity. The extreme groups are formed on the basis of orientational GSR latency. It is interesting that almost all the c hildren from the PIG group live in an area polluted by industrial neur otoxins. This fact is also discussed.
