The general objective of ESR 3 is to assess the basic auditory perception of acoustic cues relevant for speech processing in young children from 2 to 6 years. Specifically, ESR 3 will be involved in assessing the processing of the acoustic dimensions of pitch, duration and intensity with psychoacoustic, hemodynamic and electrophysiological measures in children with low, medium and high productive/receptive vocabularies. These measures will be taken longitudinally between 2 and 3 years of age French toddlers, and tested cross-linguistically to identify language-general and language-specific effects (see ESR 2).
We aim to identify cues that bear the greatest prognostic power for language delay on a single subject basis in languages that differ substantially in acoustic cue weighting.
