“…In contrast, the findings of Dhooge at al. agree with WEAVER++'s assumption that the distractor-frequency effect arises during word planning, which is also supported by other EEG and MEG evidence on the time course of semantic and Stroop-like effects of distractor words in picture naming (e.g., Piai, Roelofs, and Van der Meij, 2012;Piai, Roelofs, Jensen, Schoffelen, and Bonnefond, 2014).…”

“…For example, the N400 amplitude to perceived words is smaller for high-frequency words (low demand) compared with low-frequency words (higher demand). Also, the N400 amplitude is smaller for pictures with high-frequency than with low-frequency names (Piai, Roelofs, & Van der Meij, 2012). Moreover, the N400 amplitude to pictures and words is smaller when they are preceded by semantically related compared with unrelated pictures and words (e.g., Barrett & Rugg, 1990;Jescheniak, Hahne, & Schriefers, 2003;Jescheniak, Schriefers, Garrett, & Friederici, 2002;Lau, Almeida, Hines, & Poeppel, 2009;McPherson & Holcomb, 1999).…”

Disagreement exists about how bilingual speakers select words, in particular, whether words in another language compete, or competition is restricted to a target language, or no competition occurs. Evidence that competition occurs but is restricted to a target language comes from response time (RT) effects obtained when speakers name pictures in one language while trying to ignore distractor words in another language. Compared to unrelated distractor words, RT is longer when the picture name and distractor are semantically related, but RT is shorter when the distractor is the translation of the name of the picture in the other language. These effects suggest that distractor words from another language do not compete themselves but activate their counterparts in the target language, thereby yielding the semantic interference and translation facilitation effects. Here, we report an event-related brain potential (ERP) study testing the prediction that priming underlies both of these effects.The RTs showed semantic interference and translation facilitation effects. Moreover, the picture-word stimuli yielded an N400 response, whose amplitude was smaller on semantic and translation trials than on unrelated trials, providing evidence that interference and facilitation priming underlie the RT effects. We present the results of computer simulations showing the utility of a within-language competition account of our findings.

“…By now, a number of studies has recorded EEG in overt speech production tasks (for examples and review, see Eulitz et al, 2000;Ganushchak et al, 2011;Piai et al, 2012;Strijkers et al, 2011). The N2pc and SSVEPs have the advantage of being distributed over electrode sites contralateral to the direction of attention, such that motor activity should cancel out after collapsing across left-to-right and right-to-left naming directions.…”

Lateralized electrical brain activity reveals covert attention allocation during speaking

A B S T R A C TSpeakers usually begin to speak while only part of the utterance has been planned. Earlier work has shown that speech planning processes are reflected in speakers' eye movements as they describe visually presented objects. However, to-be-named objects can be processed to some extent before they have been fixated upon, presumably because attention can be allocated to objects covertly, without moving the eyes. The present study investigated whether EEG could track speakers' covert attention allocation as they produced short utterances to describe pairs of objects (e.g., "dog and chair"). The processing difficulty of each object was varied by presenting it in upright orientation (easy) or in upside down orientation (difficult). Background squares flickered at different frequencies in order to elicit steady-state visual evoked potentials (SSVEPs). The N2pc component, associated with the focusing of attention on an item, was detectable not only prior to speech onset, but also during speaking. The time course of the N2pc showed that attention shifted to each object in the order of mention prior to speech onset. Furthermore, greater processing difficulty increased the time speakers spent attending to each object. This demonstrates that the N2pc can track covert attention allocation in a naming task. In addition, an effect of processing difficulty at around 200-350 ms after stimulus onset revealed early attention allocation to the second to-be-named object. The flickering backgrounds elicited SSVEPs, but SSVEP amplitude was not influenced by processing difficulty. These results help complete the picture of the coordination of visual information uptake and motor output during speaking.
