Neuromagnetic fields preceding unilateral movements in dextrals and sinistrals.

As has often been observed, the great majority of sinistral individuals have two dextral parents and even persons with two sinistral parents have less than a 50 % chance of being sinistrals themselves.
Since then we've had other notable sinistrals such as Gerald Ford, Nelson Rockefeller, and George Bush.
It should be noted, as well, that studies in which sinistral individuals were included have found significantly better SIBT performances for dextrals than for sinistrals (McKeever, 1986; Rich & McKeever, 1990).
