By comparing the ERP (Event related potential) responses to words, pseudowords, and other visual stimuli we have collected evidence for both serial and parallel word recognition processes as well as their temporal activation. Characters as well as other symbols can be seen to activate the visual word form area. The sequence of characters is then recognized as a word in a process that shows a frequency effect between rare and common words, characteristic of parallel recognition. We are able to show that while semantical access would be started for common words, pseudowords show a simultaneous higher activation in a previously known serial word recognition pathway. The serial control regions also show a difference between fluent and dysfluent readers, but this difference reaches statistical significance in our data only at a relatively late time point and a single type of stimulus. More data would be needed to study the dysfluent reading process in more detail. Overall, our findings can be taken to support the dual models of serial and parallel word recognition presented in the literature.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Ann-Marie Norrgrann (anlinorr) on 2014-08-31 11:47:19.485423.
