Babies 'learn to anticipate touch' while in the womb
BABIES learn how to anticipate touch while in the womb, according to new research led by North-East scientists.
Using advanced "4D"scans, psychologists found, for the first time, that fetuses were able to predict, rather than react to, their own hand movements towards their mouths as they entered the later stages of gestation compared to earlier in a pregnancy.
The Durham-led team of researchers said that the latest findings could improve understanding about babies, especially those born prematurely, their readiness to interact socially and their ability to calm themselves by sucking on their thumb or fingers.
They said the results could also be a potential indicator of how prepared babies are for feeding and if they are developing normally.
The researchers carried out a total of 60 scans of 15 healthy fetuses at monthly intervals between 24 weeks and 36 weeks gestation.
Fetuses in the earlier stage of gestation more frequently touched the upper part and sides of their heads.
As the fetuses matured they began to increasingly touch the lower, more sensitive, part of their faces including their mouths.
By 36 weeks a significantly higher proportion of fetuses were observed opening their mouths before touching them, suggesting that later in pregnancy they were able to anticipate that their hands were about to touch their mouths, rather than reacting to the touch of their hands, the researchers said.
Increased sensitivity around a fetus' mouth at this later stage of pregnancy could mean that they have more "awareness" of mouth movement, they added.
Previous theories have suggested that movement in sequence could form the basis for the development of intention in fetuses.
The research, by Durham and Lancaster universities, published in the journal Developmental Psychobiology, involved eight girls and seven boys/
