“…Critically, the scalp topographies were similar across all experiments and showed up as negative amplitude differences over posterior sites; the remarkable consistency of this pattern strengthens the validity of the present results and informs about the distribution of early frequency effects, which have often been considered as an index for advanced lexical processing. Accordingly, the data are in line with previous reports of frequency effects within the first 200 ms, indicating that word recognition relies on the rapid processing of the visual word form (Braun et al, 2009;Dambacher et al, 2006;Hauk et al, 2006;Hauk & Pulvermüller, 2004;Penolazzi et al, 2007;Sereno et al, 1998Sereno et al, , 2003. Yet, the results also extend existing evidence since they revealed differences between experiments:…”

Article in press in Neuropsychologia [http://dx.doi.org/10.1016/j.neuropsychologia.2012.04.011] Please note that this unproofed preprint may be subject to minor changes. [May 5, 2012] SOA and the Timeline of Word Recognition 2 AbstractThree ERP experiments examined the effect of word presentation rate (i.e., stimulus onset asynchrony, SOA) on the time course of word frequency and predictability effects in sentence reading. In Experiments 1 and 2, sentences were presented word-by-word in the screen center at an SOA of 700 and 490 ms, respectively. While these rates are typical for psycholinguistic ERP research, natural reading happens at a considerably faster pace. Accordingly, Experiment 3 employed a near-normal SOA of 280 ms, which approximated the rate of normal reading. Main results can be summarized as follows: (1) The onset latency of early frequency effects decreases gradually with increasing presentation rates. (2) An early interaction between top-down and bottom-up processing is observed only under a nearnormal SOA. (3) N400 predictability effects occur later and are smaller at a near-normal (i.e., high) presentation rate than at the lower rates commonly used in ERP experiments. (4) ERP morphology is different at the shortest compared to longer SOAs. Together, the results point to a special role of a near-normal presentation rate for visual word recognition and therefore suggest that SOA should be taken into account in research of natural reading.

“…It thus seems that the adult's brain is sensitive to the dependencies among letters and positions within word-forms (sublexical orthographic units) in a very early stage of the reading process, as early as 80-120 ms after stimulus onset. Recent studies have already suggested neurophysiological correlates of sublexical orthographic processing in similar latency ranges (Coch & Mitra, 2010;Hauk, Davis, Ford, Pulvermüller, & Marslen-Wilson, 2006;, although using other measures of orthotactic constrains like tri-/bigram frequency. Our results add to these studies indicating that orthographic typicality assessed both in terms of letter position frequency and sequential constraints can modulate early ERP responses of visual word recognition.…”

a b s t r a c tThis ERP study investigated the cognitive nature of the P1-N1 components during orthographic processing. We used an implicit reading task with various types of stimuli involving different amounts of sublexical or lexical orthographic processing (words, pseudohomophones, pseudowords, nonwords, and symbols), and tested average and dyslexic readers. An orthographic regularity effect (pseudowords-nonwords contrast) was observed in the average but not in the dyslexic group. This suggests an early sensitivity to the dependencies among letters in word-forms that reflect orthographic structure, while the dyslexic brain apparently fails to be appropriately sensitive to these complex features. Moreover, in the adults the N1-response may already reflect lexical access: (i) the N1 was sensitive to the familiar vs. less familiar orthographic sequence contrast; (ii) and early effects of the phonological form (words-pseudohomophones contrast) were also found. Finally, the later N320 component was attenuated in the dyslexics, suggesting suboptimal processing in later stages of phonological analysis.

“…Indeed, Hauk and Pulvermüller (2004) also reported word frequency effects in a very similar time window between 150 and 200 ms (see also Assadollahi and Pulvermüller, 2001;Sereno, Brewer, O'Donnell, 2003;Dambacher et al, 2006, but see Polich and Donchin, 1988;Van Petten and Kutas, 1990;Rugg, 1990;Pulvermüller et al, 2001 for later effects of word frequency). Finally, Hauk et al (2006a) reported lexical and semantic processing as early as 160 ms employing linear regression analysis on neurophysiological data from a visual lexical decision task.…”

Previous research using event-related brain potentials (ERPs) suggested that phonological processing in visual word recognition occurs rather late, typically after semantic or syntactic processing. Here we show that phonological activation in visual word recognition can be observed much earlier. Using a lexical decision task, we show that ERPs to pseudohomophones (e.g., ROZE) differed from well matched spelling controls (e.g., ROFE) as early as 150 ms (P150) after stimulus onset. The pseudohomophone effect occurred as early as the word frequency effect suggesting that phonological activation occurs early enough to influence lexical access. Low-resolution electromagnetic tomography analysis (LORETA) revealed that left temporo-parietal and right fronto-temporal areas are the likely brain regions associated with the processing of phonological information at the lexical level. Altogether, the results show that phonological processes are activated early in visual word recognition and play an important role in lexical access.
