ERP and cognation

Xavier Aparicio, Katherine J Midgley, Phillip J Holcomb, He Pu, Jean-Marc Lavaur, Jonathan Grainger
Event-related potentials were recorded during the visual presentation of words in the three languages of French-English-Spanish trilinguals. Participants monitored a mixed list of unrelated non-cognate words in the three languages while performing a semantic categorization task. Words in L1 generated earlier N400 peak amplitudes than both L2 and L3 words, which peaked together. On the other hand, L2 and L3 words did differ significantly in terms of N400 amplitude, with L3 words generating greater mean amplitudes compared with L2 words...

Self-monitoring in production is critical to correct performance, and recent accounts suggest that such monitoring may occur via the detection of response conflict. The error-related negativity (ERN) is a response-locked event-related potential (ERP) that is sensitive to response conflict. The present study examines whether response conflict is detected in production by exploring a situation where multiple outputs are activated: the bilingual naming of form-related equivalents (i.e. cognates). ERPs were recorded while German-Dutch bilinguals named pictures in their first and second languages...

This study examined the role of phonological and orthographic overlap in the recognition of cognate words by recording electrophysiological and behavioral data. One hundred and ninety-two words were selected: 96 cognate words listed according to their phonological and orthographic overlap vs. 96 noncognate words. Twenty-four proficient European Portuguese-English bilinguals performed a silent reading task with a masked priming paradigm. The results showed that phonology interacts with semantic activation at N400 modulations...

ERPs were used to explore the different patterns of processing of cognate and noncognate words in the first (L1) and second (L2) language of a population of second language learners. L1 English students of French were presented with blocked lists of L1 and L2 words, and ERPs to cognates and noncognates were compared within each language block. For both languages, cognates had smaller amplitudes in the N400 component when compared with noncognates. L1 items that were cognates showed early differences in amplitude in the N400 epoch when compared with noncognates...

The present study establishes an electrophysiological index of lexical access in speech production by exploring the locus of the frequency and cognate effects during overt naming. We conducted 2 event-related potential (ERP) studies with 16 Spanish-Catalan bilinguals performing a picture naming task in Spanish (L1) and 16 Catalan-Spanish bilinguals performing a picture naming task in Spanish (L2). Behavioral results showed a clear frequency effect and an interaction between frequency and cognate status. The ERP elicited during the production of high-frequency words diverged from the low-frequency ERP between 150 and 200 ms post-target presentation and kept diverging until voice onset...

Event-related potentials (ERPs) and masked translation priming served to examine the time-course of form and meaning activation during word recognition in second language learners. Targets were repetitions of, translations of, or were unrelated to the immediately preceding prime. In Experiment 1 all targets were in the participants' L2. In Experiment 2 all targets were in the participants' L1. In Exp 1 both within-language repetition and L1-L2 translation priming produced effects on the N250 component and the N400 component...

This study addressed how bilingual speakers switch between their first and second language when speaking. Event-related brain potentials (ERPs) and naming latencies were measured while unbalanced German (L1)-Dutch (L2) speakers performed a picture-naming task. Participants named pictures either in their L1 or in their L2 (blocked language conditions), or participants switched between their first and second language unpredictably (mixed language condition). Furthermore, form similarity between translation equivalents (cognate status) was manipulated...

Hypnotic perceptual alteration affects brain function. Those hypnotic instructions that reduce perception by creating an illusory obstruction to it reduce brain response to perception in the cognate sensory cortex, as measured by event-related potential (ERP) amplitude and regional blood flow (PET). Those hypnotic instructions that affect the subject's reaction to perception activate the anterior attentional system, especially the anterior cingulate cortex in PET studies. Hypnosis involves activation without arousal and may be particularly mediated via dopaminergic pathways...
