“…This sort of inconsistency between the behavioral and the electrophysiological findings is actually consistent with previous ERP research on the N400 effect (Ruz, Madrid, Lupiánez, & Tudela, 2003;Brown & Hagoort, 1993;Holcomb, 1993). For example, Brown and Hagoort (1993) found that incongruent masked primes produced slower RTs to targets than congruent masked primes, but this effect was not carried over in the electrophysiological data-there was no corresponding N400 effect for masked incongruent items.…”

Abstract■ Previous research has demonstrated a link between language and action in the brain. The present study investigates the strength of this neural relationship by focusing on a potential interface between the two systems: cospeech iconic gesture. Participants performed a Stroop-like task in which they watched videos of a man and a woman speaking and gesturing about common actions. The videos differed as to whether the gender of the speaker and gesturer was the same or different and whether the content of the speech and gesture was congruent or incongruent. The task was to identify whether a man or a woman produced the spoken portion of the videos while accuracy rates, RTs, and ERPs were recorded to the words. Although not relevant to the task, participants paid attention to the semantic relationship between the speech and the gesture, producing a larger N400 to words accompanied by incongruent versus congruent gestures. In addition, RTs were slower to incongruent versus congruent gesture-speech stimuli, but this effect was greater when the gender of the gesturer and speaker was the same versus different. These results suggest that the integration of gesture and speech during language comprehension is automatic but also under some degree of neurocognitive control. ■

“…Some variables associated to early modulations are lexical features (Sereno, Rayner, & Posner, 1998;Dehaene, 1995), word frequency (Sereno, Brewer, & O'Donnell, 2003;, or even semantic factors (Pulvermuller, Assadollahi, & Elbert, 2001). Along the same lines, repetition, phonological, and semantic priming effects have been reported during similar time windows (Holcomb & Grainger, 2006;Proverbio et al, 2004;Ruz, Madrid, Lupiáñez, & Tudela, 2003;Abdullaev & Posner, 1998). These effects of stimulus attributes suggest that the language system in the brain is tuned to extract some word-related characteristics at a very fast pace.…”

Abstract& Selective attention has the potential to enhance the initial processing of objects, their spatial locations, or their constituent features. The present study shows that this capacity to modulate initial stages of processing also applies to linguistic attributes. A cueing paradigm focused attention at different levels of word representations on a trial-by-trial basis to study the time course of attentional modulation on visual word processing by means of a high-density electrophysiology recording system. Attention to different linguistic attributes modulated components related to semantic, phonological, and orthographic stages of word processing. Crucially, the N200, associated with initial stages of orthographic decoding, was enhanced by attention to the letter pattern of words. These results suggest that top-down attention has the capacity to enhance initial perceptual stages of visual word processing and support the flexibility of attention in modulating different levels of information processing depending on task goals. &

“…Two components are known to be related to semantic priming: a negative component peaking 400 ms after stimulus onset, the "N400" (Kutas & Hillyard, 1980, 1982, 1989Kutas & Van Petten, 1988;Van Petten, 1995), and a positive component appearing later called "Late Positive Complex" (LPC) (Besson & Kutas, 1993;Cameli & Phillips, 2000;Curran, Tucker, Kutas, & Posner, 1993;Juottonen, Revonsuo, & Lang, 1996;Kostova, Passerieux, Laurent, Saint-Georges, & Hardy-Bayle, 2003;Misra & Holcomb, 2003;Miyamoto, Katayama, & Koyama, 1998;Nigam, Hoffman, & Simons, 1992;Radeau, Besson, Fonteneau, & Castro, 1998;Salmon & Pratt, 2002;Sitnikova, Kuperberg, & Holcomb, 2003). The semantic priming indexed by the N400 seems to be generated by implicit (e.g., Anderson & Holcomb, 1995;Connolly, Phillips, Stewart, & Brake, 1992;Deacon, Uhm, Ritter, Hewitt, & Dynowska, 1999;Deacon, Hewitt, Yang, & Nagata, 2000;Holcomb, 1988Holcomb, , 1993Kiefer, 2002;Kiefer & Spitzer, 2000;Misra & Holcomb, 2003;Schnyer, Allen, & Forster, 1997;Stenberg, Lindgren, Johansson, Olsson, & Rosen, 2000) and explicit (e.g., Brown & Hagoort, 1993;Ruz, Madrid, Lupanez, & Tudela, 2003) processes. Unlike the N400 effect (i.e., ERP to incongruent minus ERP to congruent targets), the LPC effect would relate only to explicit processing with the activation of a postlexical integrative mechanism (Juottonen et al, 1996).…”

Sex Differences in Two Event-Related Potentials Components Related to Semantic Priming

Although sex differences in language processing are well documented in behavioral studies, only a few electrophysiological studies have explored this topic. We analyzed sex differences in two language-related components of event-related potentials (ERPs): the N400 and the Late Positive Complex (LPC). Ten men and 10 women, matched by age and handedness, participated in the study. Two semantic priming paradigms were presented: word pairs (60 congruent and 60 incongruent) and sentences (50 with congruent and 50 with incongruent ending words). In addition, the effect of context was investigated by a comparison between ERP effects obtained in single word priming and sentential priming. The N400 effect was earlier and larger in women, and the LPC effect was larger in men. Furthermore, the LPC effect in men, but not in women, was much larger with sentence priming than with word priming, suggesting that the LPC effect may be more dependent on context in men than in women. The opposite sex difference on the two ERP components indicates different underlying mechanisms. While the LPC effect is thought to be generated by purely explicit mechanisms, such as postlexical integrative processes, the N400 effect may be also governed by prelexical implicit and explicit mechanisms. Our results were consistent with the notion of more automated processing of language in women than in men.
