New Research: Handedness Determined by 10 Weeks in the Womb



BELFAST — New research from Irish scientists has revealed that a person's dominant hand is determined by 10 weeks gestation. Scientists previously thought the dominant hand was not determined until at least three years old.

The researchers noted that, by using ultrasound, the determination of a preferred hand was set at just 10 weeks, and correlates to the dominant hand later in life.

As reported by New Scientist magazine, of 60 babies who sucked their right thumbs in the womb, 100 percent were right handed when investigated at age 10 to 12, whereas of 15 who sucked their left thumbs in the womb, 10 remained left-handed, while five switched to right-handedness. Furthermore, the 60-to-15 proportion mirrors the proportions of right to left-handed people in the adult population.

Research finds that Infants Need Mother's Gaze for Neural Development

Science is starting to show what family advocates have pointed out for years, that mothers and fathers and especially day care workers, are not interchangeable in child development. Babette Francis, a pro-family lobbyist who has spent years tracking the UN's 'gender agenda,' has written extensively on the damage done to families – and the laws that protect them – by feminist notions of gender identity. Francis writes in an article in News Weekly, about scientific findings showing the physical necessity of the presence of a child's mother in his neural development.

Christine De Vollmer, president of the Latin-America Alliance for the Family gave a paper at the World Congress of Families in Mexico. She cited studies that demonstrate that the cerebral cortex of the human brain does not grow automatically but according to the stimulation received while it is in the main growth phase, i.e., during the first six years. De Vollmer said, “New, non-invasive studies of brain development show that the cortico-limbic lobes also develop in response to stimulation – and that stimulation is the love and caresses of the baby's mother from the moment of birth.”

In the talk, De Vollmer cited Dr Allan N. Schore's important study, 'Affect Regulation and the Origin of the Self: The Neurobiology of Emotional Development.' Schore said, “New discoveries establish the significance of those hours of mothers gazing at their babies. It seems a detectable energy flows from the mother's brain through her eyes into the baby's eyes and stimulates the baby's brain.”

Francis warns that the necessary connection to stimulate normal brain development cannot be achieved by part-time caregivers.
