2020, Brain ResearchCitation Excerpt :Visual N1 and selection negativity. With the split-visual field presentation, laterally presented stimuli are expected to elicit larger N1 responses and a sustained selection negativity over the hemisphere contralateral to the visual field of presentation (Federmeier et al., 2005; Federmeier & Kutas, 2002; Neville et al., 1982). Fig. 3 plots the responses recorded over representative electrode sites.
Unique N170 signatures to words and faces in deaf ASL signers reflect experience-specific adaptations during early visual processing
2020, NeuropsychologiaCitation Excerpt :Traditionally, in hearing readers, increased RH recruitment has been associated with poorer reading skill (Emmorey et al., 2017; Laszlo and Sacchi, 2015; Shaywitz and Shaywitz, 2005) and regarded as maladaptive, perhaps related to the fact that the right occipito-temporal regions might be responsible for coarser level processing or might process words as visual objects, which could consequently lead to less efficient or less precise orthographic representations (Laszlo and Sacchi, 2015). Neville and colleagues (Neville et al., 1982a, 1984; Neville et al., 1982b) also reported reduced N170 asymmetry to visually presented words in deaf individuals and originally attributed the outcome to the possibility that their deaf participants may have not had full mastery of English grammar because English was acquired as a second language. Given that our participants rated themselves as proficient in written English (mean 6 on a 1–7 scale; 7 = “like native”), this explanation for our results is unlikely.
Hemispheric differences and similarities in comprehending more and less predictable sentences
2016, NeuropsychologiaCitation Excerpt :The factors of VF and Hemisphere interacted [F(1, 31)=72.33, p<.0001] as expected, with enhanced N1 amplitude over LH scalp sites for RVF presentation, and the opposite pattern for LVF presentation (Fig. 1). We also examined a contralateral selection negativity—an ERP response that has similarly been observed in several prior studies using lateralized language stimuli (e.g., Federmeier and Kutas, 1999b, 2002; Coulson et al., 2005; Federmeier et al., 2005; Neville et al., 1982). To characterize this effect, which manifests as a sustained negativity effect over lateral posterior electrode sites, we performed the same ANOVA as for the N1, but used a 300–1000 ms time window.
Sublexical ambiguity effect in reading Chinese disyllabic compounds
2011, Brain and LanguageCitation Excerpt :The amplitude of the N1 was larger over the right than the left hemisphere (−1.1 vs. 1.9 μV) when stimuli appeared in the LVF/RH, and it showed reverse asymmetry (2.4 vs. −1.6 μV) when stimuli appeared in the RVF/LH [VF × laterality, F(1, 20) = 53.5, p < .001]. The reversed asymmetries of the visual N1 contingent on hemifield were as expected; it confirmed that the procedures for maintaining central gaze fixation and rejection of trials with lateral eye movements were adequate to ensure lateralized processing, at least at the level of visual processing indexed by the N1 (Hillyard & Anllo-Vento, 1998; Neville, Kutas, & Schmidt, 1982). Previous studies measuring ERPs to lateralized visual stimuli have reported a sustained late negative-going effect (has been referred to as the selection negativity) over lateral and posterior scalp sites contralateral to the visual filed of stimulus presentation (Federmeier, Mai, & Kutas, 2005; Neville et al., 1982), and we also observed a visually similar effect in this study (Fig. 3).
