Forschungsinteressen

• Neurokognitive Grundlagen phonologischer Verarbeitung bei Säuglingen, Vorschulkindern und Schulkindern im Hinblick auf den Zusammenhang mit späteren Schwierigkeiten beim Schriftspracherwerb
• Entwicklung eines früh-einsetzendes Screeningverfahrens für die Erkennung eines Risikos für spätere Lese-Rechtschreibschwäche
• Einflussfaktoren auf die phonologische Entwicklung bei Säuglingen, Vorschulkindern und Schulkindern (z.B. Depressivität der Mütter nach der Geburt, endokrinologische Faktoren und genetische Faktoren)

 

Forschungsmethoden
