Information flow in the mental lexicon during speech planning: evidence from event-related brain potentials.

چکیده
A major issue in speech production research is the question of how speakers retrieve words from the so-called mental lexicon. Current models of lexical retrieval converge on the assumption that category associates of a target word are semantically activated during speech planning. However, the question of whether these competitors are also phonologically activated is less agreed on. Past research has addressed this issue by testing whether lexical retrieval of a picture name (e.g. sheep) affects, or is affected by, the processing of a word that is phonologically related to a semantic category associate to the picture name (e.g. goal, phonologically related to goat). Behavioral studies have failed to obtain such so-called mediated priming effects, but have been questioned on the grounds of possibly insufficient task sensitivity. As such priming effects have reliably been obtained with event-related brain potentials in word recognition, we used this approach for testing these effects in lexical retrieval during speech planning. Our results consistently demonstrate the absence of mediated priming effects, putting strong constraints on the activation flow in the mental lexicon during speech planning.

Neurobiological evidence for abstract phonological representations in the mental lexicon during speech recognition.
A central issue in speech recognition is how contrastive phonemic information is stored in the mental lexicon. The conventional view assumes that this information is closely related to acoustic properties of speech. Considering that no world is ever pronounced alike twice and that the brain has limited capacities to manage information, an opposing view proposes abstract underspecified represent...

متن کاملStem allomorphy in the Spanish mental lexicon: evidence from behavioral and ERP experiments.
This study presents results from a nonce-word elicited production task and a reading experiment using event-related brain potentials (ERPs) investigating finite forms of Spanish verbs which consist of marked stems and regular person and number agreement suffixes. The first experiment showed that unmarked stems are productively extended to nonce words, whereas marked stems generalize more restri...

Native-like Event-related Potentials in Processing the Second Language Syntax: Late Bilinguals
Background: The P600 brain wave reflects syntactic processes in response to different first language (L1) syntactic violations, syntactic repair, structural reanalysis, and specific semantic components. Unlike semantic processing, aspects of the second language (L2) syntactic processing differ from the L1, particularly at lower levels of proficiency. At higher L2 proficiency, syntactic violatio...
