‘Left-Cradling Bias’ Linked to Better Social Cognitive Abilities in Children
[Source: Science Daily]
The new findings, which also show deeply inbuilt facial recognition skills which enable children to interpret even simple approximations as human faces, suggest the children’s cradling preference could help to indicate some social developmental disorders.
The study builds on previous knowledge of a ‘left-cradling bias’ — the phenomenon that humans will typically cradle a baby on their left side, enabling both parent and child to keep the other in their left visual field — which is unrelated to dominance of the use of right or left hand. Information from the left visual field is processed by the right hemisphere of the brain, which is associated with emotion and the perception of facial expression.
