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

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

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 resear...

Mapping Speech Sound to Mental Representation: Neurophonological Evidence from Event-Related Brain Potentials

Event-related brain potentials during the monitoring of speech errors

When we perceive speech, our goal is to extract the meaning of the verbal message which includes semantic processing. However, how deeply do we process speech in different situations? In two experiments, native Dutch participants heard spoken sentences describing simultaneously presented pictures. Sentences either correctly described the pictures or contained an anomalous final word (i.e. a sem...

Exploring the activation of semantic and phonological codes during speech planning with event-related brain potentials.

We present a new technique for studying the activation of semantic and phonological codes in speech planning using event-related brain potentials (ERPs) that extend a well-established behavioral procedure from speech production research. It combines a delayed picture-naming task with a priming procedure. While participants prepared the production of a depicted object's name, they heard an audit...

On-line Integration of Semantic Information from Speech and Gesture: Insights from Event-related Brain Potentials

During language comprehension, listeners use the global semantic representation from previous sentence or discourse context to immediately integrate the meaning of each upcoming word into the unfolding message-level representation. Here we investigate whether communicative gestures that often spontaneously co-occur with speech are processed in a similar fashion and integrated to previous senten...
