Dear Parent,

As you well know already, touch is a very important sense in a baby’s life and it is the first one to develop. Along with your voice, your touch is what you mostly depend on to interact with your child throughout infancy. When you want to play, reassure or soothe your baby you will most likely find yourself doing so through the sense of touch.

We know that touch has positive and long-term effects on mental and physical health, but what we lack is the understanding of how does it happen.

Here at the BabyLab we are interested in ‘social touch’ (slow gentle caressing). How early does the infant brain start perceiving this type of touch as different from other tactile stimulation and how does that affect the infant’s attention and arousal states? These are the questions we are trying to answer.

If you agree for your child to participate he/she will take part in a study in which he/she will be stroked with the hand on one arm (social touch) and with a toothbrush (non-social touch) on the other, while we record the brain activity. The procedure will take about 15 minutes. You or your child are free to stop the study and withdraw at any time.

THANKS FOR TAKING PART IN OUR STUDIES !
