Neural Correlates of Tactile Prediction

Summary

This project aims to measure repetition suppression and tactile prediction using high-resolution electroencephalography in preschoolers, in order to describe the responses as a function of age, gestational age of birth and the presence of a neurodevelopmental disorder. We will include 100 children aged 2 or 6 years: 25 2-year-olds born prematurely, 25 2-year-olds born at term, 25 6-year-olds with typical development and 25 6-year-olds with neurodevelopmental disorders. We will perform several behavioral evaluations to analyze the results in view of the quality of development.

Conditions

• Neurodevelopmental Disorders
• Premature Birth

Interventions

DEVICE

electroencephalography

128-channel electroencephalography

DEVICE

Tactile stimulation

Vibrotactile sequence on the forearm

BEHAVIORAL

Attention Network task (computerized)

Computer-based game challenging orienting and executive attention. The subject must chose which side an animal is going, using left and right buttons, depending on the validity of a cue and the congruency of flankers.

BEHAVIORAL

Head-toes-knees-schoulders

Following motor commands such as touch your head when they are congruent or incongruent.

BEHAVIORAL

Laby 5-12

Test of motor planning using labyrinths

BEHAVIORAL

M-ABC 2

Test of motor functions using various subtests of gross and fine motor function.

BEHAVIORAL

Stroop animals

Stroop test for preK children using animals instead of words
