Right-handedness: a consequence of infant supine head-orientation preference?
نویسنده
چکیده
Most newborn infants (65 percent) preferred to lie with their heads turned to the right, whereas 15 percent showed a distinct preference for the left. Orientation preference is maintained for at least 2 months and predicts preferential hand use in reaching tasks at both 16 and 22 weeks. Right head-orientation preference in early infancy may contribute to the early development of right-handedness.

Head orientation and handedness trajectory in rhesus monkey infants (Macaca mulatta).
In human and chimpanzee infants, neonatal rightward supine head orientation bias predicts later right hand use preference. In an evolutionarily older primate species such as the rhesus monkey, a left hand preference has been reported, but there are no data on head orientation biases. Supine head orientation bias was measured experimentally in 16 rhesus monkey neonates and compared with prone he...
متن کاملHead Orientation position during birth and in infant neonatal period, and hand preference at nineteen weeks.
This study of lateral preferences of normal full-term infants found, as predicted, that infants who were delivered from a left occiput anterior or transverse birth position (head turned to the right) exhibited a neonatal right supine head orientation and a right-hand preference in visually guided reaching tasks at 19 weeks. Contrary to prediction, infants delivered from a right occiput anterior...
متن کاملExperience-dependent emergence of functional asymmetries.
Right head-turning preference is assumed to be a developmental default. This motor asymmetry seems to influence the development of other lateralised behaviours-such as handedness-as a consequence of orienting vision towards the right side of the body. To document the role of visual experience in promoting lateralised functions we assessed head-turning preference and handedness in a group of con...
متن کاملKissing right? On the consistency of the head-turning bias in kissing.
The present study investigated the consistency of the head-turning bias in kissing. In particular we addressed what happens if a person who prefers to kiss with the head turned to the right kisses a person who prefers to kiss with the head turned to the left. To this end, participants (N=57) were required to kiss a life-sized doll's head rotated in different orientations that were either compat...
متن کاملHead-turning asymmetries during kissing and their association with lateral preference.
A head-turning bias to the right side is one of the earliest functional asymmetries in human development and is already present during the final weeks of gestation. To test whether head-turning preference is related to other lateral preferences in adults, kissing behaviour of participants towards a symmetrical doll was observed to assess their spontaneous head-turning preference. Additionally, ...
