Main objective of ESR 2 is to answer if and how the neural correlates of perceiving acoustic cues relevant for speech recognition (such as duration, pitch, and intensity) in speech and non-speech sounds differ between groups of different vocabulary sizes (i.e., low, medium, and large productive/receptive vocabulary size). Psychoacoustic, hemodynamic and electrophysiological measures will be applied longitudinally with German children between 2 and 3 years of age. Cross-linguistic comparisons will identify language-general and language-specific effects (see ESR 3).

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.
