My main research interest is the development of the relationship between phonology and lexicon in child language acquisition in terms of perception and production. My aim is to investigate the relationship between phonological perception skills and lexical representations using two different methods: EEG and Eye-tracking. EEG measures brain responses in event-related potentials (ERPs).I will explore one such brain response: the N400-effect, a specific reaction in brain activation 400 ms after stimulus onset. The N400-effect seems to be relevant in the process of early word acquisition and to be connected to semantic integration. Eye-tracking measures the gaze behavior and allows us to draw conclusions about the phonological representations of early words. I would like to relate the perceptual responses to the productive abilities of the individual child. The combination of two linguistic domains –phonology and the lexicon – and the link between perception and production is expected to play an essential role in early language acquisition.

In the first part of the talk, I will give a general background about the theories as well as methodology and present previous studies on the acquisition of the lexicon and phonology. In the second part I will present results from a pilot study with 17-month-old children and tentative findings of my current study with 24-month-old children.
