Word frequency and recency effects in spontaneous language processing: an intracranial EEG study

Word frequency and recency effects are important topics in linguistics. This applies especially to usage-based approaches, which proceed from the assumption that linguistic experience has an influence on language usage and processing. While there is a wide range of linguistic and psycholinguistic studies on frequency and recency effects, their neuronal basis has been relatively sparsely investigated.
My PhD project addresses this question. I am using a unique multimodal corpus which consists of naturally produced everyday language and simultaneously recorded neuronal signals to examine the neural correlates of frequency and recency of lexical items. Electrocorticographic (ECoG) data have an excellent spatiotemporal resolution and is therefore particularly well suited to investigate these phenomena in such dynamic processes as human verbal communication.
