[Finger spreading as an indicator of psychomotor activity and laterality].
In 23 healthy right- and left-handers and in 8 psychotic patients the angels between fingers were measured after maximal spreading. It can be demonstrated, that there are differences in spreading out between right- and lefthanders. The dominance of the right hand in right-handers is fluctuating. In depressiv psychotics and patients after schizophrenia we found decrease of spreading out. The laterality imbalance in psychoses we interprete as a sign of hemispherial dysfunktion.
