Neural changes underlying early stages of L2 vocabulary acquisition.
TL;DR: Electrophysiological changes underlying the earliest stages of second language vocabulary acquisition are examined by recording event-related potentials (ERPs) within the first week of learning, suggesting that the neural changes captured during adult second language acquisition are more rapid than previously shown.

Language Effects in Trilinguals: An ERP Study.

TL;DR: The effects of peak N400 latency is interpreted as reflecting the special status of the L1 relative to later acquired languages, rather than proficiency in that language per se, and the mean amplitude difference between L2 and L3 is thought to reflect different levels of fluency in these two languages.
Testing for Nonselective Bilingual Lexical Access Using L1 Attrited Bilinguals.
TL;DR: Spanish–English bilinguals demonstrated an N400 effect of L1 attrition during implicit L1 processing in a second language (L2) semantic judgment task, indicating the contribution of variable L1 lexical access during L2 processing, which is incompatible with Costa and colleagues’ selective model.

A Neural Field Model of Word Repetition Effects in Early Time-Course ERPs in Spoken Word Perception.
TL;DR: A neural field model is presented which successfully replicates the effect of immediate auditory repetition of monosyllabic words and fits it to a component of a well-studied mechanism for analyzing language processing, the event-related potential (ERP).

A PDP Model for Capturing N400 Effects in Early L2 Learners during Bilingual Word Reading Tasks
TL;DR: A PDP architecture for a PDP model of bilingual word processing, which can successfully capture several known N400 effects in early bilingual wordprocessing, including the “orthographic neighborhood size” effect in addition to other known effects such as the ”pseudoword effect”.
