“…Further evidence that the RH is capable of message-level processing was obtained in an ERP study (Coulson, Federmeier, Van Petten, & Kutas, 2005) that varied sentence congruity and lexical association independently, equating cloze probability across associated versus nonassociated conditions in sentence contexts similar to those used in Faust, Bar-lev, & Chiarello (2003). The responses for both VFs showed robust priming for lexical associates out of context.…”

“…Prior ERP studies have shown that both hemispheres are broadly sensitive to basic manipulations of plausibility/expectancy (Federmeier & Kutas, 1999a;Coulson, Federmeier, Van Petten, & Kutas, 2005;Federmeier, Mai, & Kutas, 2005), manifested as larger N400 amplitudes to implausible or unexpected endings as compared with N400s to expected endings. However, such studies have also indicated that the two hemispheres use context information differently, as facilitation for unexpected endings related to a predicted completion is observed on N400 responses only with RVF/lh presentation (Federmeier & Kutas, 1999a), and as effects of expectancy on the amplitude of the P2, a component linked to higher-order visual processing, are also evident only for RVF/lh items (Federmeier & Kutas, 2002;Federmeier, Mai, & Kutas, 2005).…”

“…Federmeier & Kutas, 1999a) demonstrating that ERP responses to highly expected stimuli and responses to wholly unexpected stimuli are often strikingly similar across the two VFs. Such similarity in the N400 "range" across the two hemispheres mitigates some of the concerns raised about behavioral work (where standing differences in response time and accuracy across the two VFs can make it difficult to interpret and compare effect sizes), and provides evidence that both hemispheres are sensitive to message-level context information.Further evidence that the RH is capable of message-level processing was obtained in an ERP study (Coulson, Federmeier, Van Petten, & Kutas, 2005) that varied sentence congruity and lexical association independently, equating cloze probability across associated versus nonassociated conditions in sentence contexts similar to those used in Faust, Bar-lev, & Chiarello (2003).

The cerebral hemispheres have been shown to be differentially sensitive to sentence-level information; in particular, it has been suggested that only the left hemisphere (LH) makes predictions about upcoming items, while the right (RH) processes words in a more integrative fashion. The current study used event-related potentials to jointly examine the effects of expectancy and sentential constraint on word processing. Expected and unexpected but plausible words matched for contextual fit were inserted into strongly and weakly constraining sentence frames and presented to the left and right visual fields (LVF and RVF). Consistent with the prediction/integration view, the P2 was sensitive to constraint: words in strongly constraining contexts elicited larger P2s than those in less predictive contexts, for RVF/lh presentation only. N400 responses for both VFs departed from the typical pattern of amplitudes graded by cloze probability. Expected endings in strongly and weakly constraining contexts were facilitated to a similar degree with RVF/lh presentation, and expected endings in weakly constraining contexts were not facilitated compared to unexpected endings in those contexts for LVF/rh presentation. These data suggest that responses seen for central presentation reflect contributions from both hemispheres. Finally, a late positivity, larger for unexpected endings in strongly constraining contexts, observed for these stimuli with central presentation was not seen here for either VF. Thus, some phenomena observed with central presentation may be an emergent property of mechanisms that require interhemispheric cooperation. These data highlight the importance of understanding hemispheric asymmetries and their implications for normal language processing.For over a century, language processing has been recognized as one of the most prominent examples of hemispheric asymmetry in cerebral function. The fact that language function can be severely disrupted after damage to the left hemisphere (LH), whereas language deficits after right hemisphere (RH) damage are often much more subtle, led to the initial inference that most or all language processing arises from LH functions. More recently, an extensive body of evidence from behavioral, neuropsychological, electrophysiological, and hemodynamic neuroimaging studies has demonstrated not only that language comprehension is composed of bilateral processes, but also that the two hemispheres make qualitatively different contributions to comprehension (see, e.g., . Such findings underscore the necessity of uncovering the nature of, and the differences between, the processing computations Corresponding author: Edward W.

Although associative recognition tasks are traditionally viewed as requiring recollection, recent research suggests a role for familiarity if to-be-remembered stimuli are perceived as unitized. Here we use Event-Related Potentials (ERPs) to examine the relationship between stimulus properties and encoding strategy on the engagement of familiarity during associative recognition. Participants studied word-pairs containing an association (e.g. traffic-jam) or an unassociated semantic relationship (e.g. violin-guitar), using either item or interactive imagery. At test, participants were required to recognize if word-pairs were presented in the same pairing as study, were rearranged, or new. We hypothesized that adopting a strategy of interactive imagery during encoding (i.e. encouraging unitization) would enhance familiarity for unassociated word-pairs, but would have no effect on association pairs because they are already perceived as unitized. As expected, overall recognition performance was better for word-pairs encoded with interactive imagery, and for association than semantic word-pairs. ERPs recorded at test revealed an interaction between encoding strategy and stimulus properties. Association word-pairs elicited similar bilateral frontal (familiarity) and left parietal (recollection) old/new effects following item and interactive imagery. By contrast, for semantic word-pairs, the left parietal effect was equivalent across conditions, but the bilateral frontal effect was enhanced for the interactive imagery condition. The ERP results suggest that an encoding strategy of interactive imagery can enhance familiarity during associative recognition, but this effect is ultimately dependent on the properties of the stimuli to-be-remembered and the nature of the representations that underlie them.

“…If, instead, syntactic structures are closely bound to specific lexical entries and syntactic structures are accessed and activated via specific words, only the repeated condition should lead to a reduction in the amplitude of the P600 at the word by in the target sentences. N400 modulations as a function of semantic facilitation may occur at the repeated past participle (e.g., Besson & Kutas, 1993;Ledoux et al, 2007) but may not be present for the synonymous participles, because semantic priming effects are not always observed when the preceding sentence or discourse context is highly constraining (e.g., Camblin, Gordon, & Swaab, 2007;Coulson, Federmeier, Van Petten, & Kutas, 2005;Van Petten, Weckerly, McIsaac, & Kutas, 1997). Alternatively, if facilitative effects in processing target sentences are not related to priming of the syntactic structure per se but instead result from priming as a function of the semantic match between the prime and the target sentences because the past participles are repeated or synonymous, we would not predict a reduced P600 on by in either of the conditions.…”

Event-related potentials and eye tracking were used to investigate the nature of priming effects in sentence comprehension. Participants read 2 sentences (a prime sentence and a target sentence), both of which had a difficult and ambiguous sentence structure. The prime and target sentences contained either the same verb or verbs that were very close in meaning. Priming effects were robust when the verb was repeated. In the event-related potential experiment, the amplitude of the P600 was reduced in target sentences that followed prime sentences with the same verb but not in prime sentences with a synonymous verb. In the eye-tracking experiment, total reading times on the disambiguating region were reduced when the targets followed prime sentences with the same verb but not when targets followed prime sentences with a synonymous verb. The fact that verb overlap greatly boosted priming effects in reduced relative sentences may indicate that verb argument structures play an important role in online parsing.
