Pre-activation negativity (PrAN) in brain potentials to unfolding words

Pre-activation negativity (PrAN) in brain potentials to unfolding words

We describe an ERP effect termed the ‘pre-activation negativity’ (PrAN), which is proposed to index the degree of pre-activation of upcoming word-internal morphemes in speech processing. Using lexical competition measures based on word-initial speech fragments (WIFs), as well as statistical analyses...
