NCT04495660

Brief Summary

The principal aim of this study is to evaluate the cortical developement of perceptual skills and executive functions over time, in children with cochlear implants aged 10-24 months and 3-7 years compared with normally hearing subjects (NHS). To do this, the investigator will use functional Near InfraRed Spectroscopy (fNIRS) during 4 tasks that engage the childs perceptual and cognitive skills over a period of 18 months. The performance scores obtained by each participants as well as the cortical activity will be analysed and decrypted.

Interventions

Functional neuroimaging examination by fNIRS at each follow-up visit for all children of both cohorts: this non-invasive imaging technique involves the installation of a cap carrying electrodes to collect brain activity on the surface of the scalp , during stimulation. It is very insensitive to movement and therefore represents a method particularly suitable for its use in children. In addition, this technique is compatible with the cochlear implant. It will be used during 6 tasks adapted to each cohort

Passive perceptual stimulation: For this passive task the child is on his parents' lap in front of a screen. He will see images, hear everyday noises and watch small videos. Duration 8-10 minutes.

Task A not BBEHAVIORAL

Task A not B: the child will play with an adult who will hide an object under a cloth several times. The child will have to find the hidden object. Duration 10 minutes maximum

Perceptual Go-No-Go: This perceptual task consists in the discrimination of images (faces) and sounds (words) through 3 conditions (auditory, visual and visuo-auditory) presented independently of each other and lasts 15 to 20 minutes in total. It is presented by means of a computer

Verbal memory task :the child will be presented with 5 lists of 5 words which he will have to restore after a predefined delay of a few seconds. Its duration does not exceed 10 minutes.

The sensory room: the child will sit in the middle of a carpet and play with the adult. He will hear everyday noises and see light effects. Duration 8-10 minutes
