The goal of this study is to investigate the preferential responses of speech neural systems in infants.
The main question it aims to answer is to determine whether the oscillatory synchronization capacity is associated with children's language level (i.e. vocabulary).
Participants will be presented with synthetically modulated stimuli at three frequency scales: 4 Hz, 5 Hz and 30 Hz.

| Magnetoencephalography (MEG) | Behavioral | Stimuli will be presented binaurally through headphones at 60 decibel sound pressure level (dB SPL). Conditions are presented in a pseudo-random order with an inter-stimulus interval of ~800 ms on average (range: 600 ms to 1000 ms). The duration of the stimuli is fixed: 2 seconds, in order to guarantee a minimum number of cycles. |
