ome people believe that we have unconscious memories from the moment we were conceived.

Sounds crazy?

A recent study has shed more light into a baby’s memory before birth.

The study on late stage, unborn babies has found that learning can occur from week 34 of the pregnancy.

If you’ve been listening to Gracie by Ben Folds on repeat during your baths, or telling your unborn baby just how much you love her each day, there’s a chance she might remember.

The research, which was published in the journal Infant Behaviour & Development, suggests that babies begin to form memories and acquire knowledge earlier than previously thought. Previous research concluded that learning was able to take place at 37 weeks, but this study has found proof of learning up to three weeks sooner.

How Can Researchers Tell If Babies Have Memories?

The researchers used the ‘cardiac orienting response’, a small change in heart rate, to determine when a fetus remembered. This response is believed to be a response to a stimulus, and many believe it can be used to determine whether learning has taken place.

During the study, mothers-to-be were asked to read out an unfamiliar nursery rhyme twice a day between weeks 28 and 34 of the pregnancy.

The participants were invited in for testing at 28, 32, 33, 34, 36 and 38 weeks of pregnancy. The testing was to determine whether the fetus recognised the nursery rhyme.

In order to be sure, a recording of an unfamiliar woman reading the nursery rhyme was played during testing. This was done to make sure the baby was not simply reacting to the familiar sound of the mother’s voice. If the heart rate slowed, this was taken as proof that the baby recognised the words being spoken.

At 34 weeks, participants were told not to repeat the nursery rhyme again. This was to identify how long the memory lasted. Testing found that by 34 weeks, the babies began to respond to the nursery rhyme. This response continued during testing until around 38 weeks, or four weeks after the mother-to-be stopped reading the nursery rhyme aloud each day.

A total of 32 women took part in the study. A control group was used to give a clearer understanding of fetal memory. In the control group testing, a recording of a woman reading a new nursery rhyme was played. The researchers found that the heart rates of these babies accelerated in response to the new rhyme.

What Does This Research Mean?

This research gives a greater understanding of early learning and memory. It is hoped that it will influence how preterm babies are cared for. The more research we have about the womb environment, the more we can aid preterm babies. This research might help us understand how the mother’s voice could be used to stimulate preterm infants.

  1. As a hypnotherapist I have had several clients regress to the wonb where issues of fear and anxiety began. Have also had some regressing to actual birth around fears and phobias. It is real

  2. My most profound and long lasting healing experience centred around the fact that my mother was under severe pressure to have me aborted. I spent most of my life “aborting” myself, until I re-experienced this threat on my life and was able to get in touch with and release the grief of all those self-abortive experiences throughout my life.

  3. I had a playlist of Mozart that I continued to play during my pregnancy. While I was pregnant and played it, I could tell a difference in his activity. After Tyler was born I played the same music and he recognized it! When he would cry I would turn on that music. It would soothe him instantly almost every time.
