On determining ERP components}, issn = {0018-9294}, year = {2004}, abstract = {In most experiments using event-related brain potentials (ERPs), there is a straightforward way to define-on theoretical grounds-which of the conditions tested is the experimental condition and which is the control condition. It, however, theoretical assumptions do not give sufficient and unambiguous information to decide this question, then the interpretation of an ERP effect becomes difficult, especially if one takes into account that certain effects can be both a positivity or a negativity on the basis of the morphology of the pattern as well as with respect to peak latency (regard for example, N400 and P345). Exemplified with an ERP experiment on language processing, we present such a critical case and offer a possible solution on the basis of nonlinear data analysis. We show that a generalized polarity histogram, the word statistics of symbolic dynamics, is in principle able to distinguish negative going ERP components from positive ones when an appropriate encoding strategy, the half wave encoding is employed. We propose statistical criteria which allow to determine ERP components on purely methodological grounds}, language = {en} } @article{SaddyDrenhausFrisch2004, author = {Saddy, Douglas and Drenhaus, Heiner and Frisch, Stefan}, title = {Processing polarity items : Contrastive licensing costs}, issn = {0093-934X}, year = {2004}, abstract = {We describe an experiment that investigated the failure to license polarity items in German using event-related brain potentials (ERPs). The results reveal distinct processing reflexes associated with failure to license positive polarity items in comparison to failure to license negative polarity items. Failure to license both negative and positive polarity items elicited an N400 component reflecting semantic integration cost. Failure to license positive polarity items, however, also elicited a P600 component. The additional P600 in the positive polarity violations may reflect higher processing complexity associated with a negative operator. This difference between the two types of violation suggests that the processing of negative and positive polarity items does not involve identical mechanisms. (C) 2003 Elsevier Inc.

This paper investigates what role morphological case information plays during the parser's detection of an ungrammaticality or its recognition that a reanalysis is necessary. First, we compare double nominative with double accusative ungrammaticalities in a word by word, speeded grammaticality task and in this way show that only double nominatives lead to a so-called "illusion of grammaticality" (a low rate of ungrammaticality detection). This illusion was found to disappear when the second argument was realized by a pronoun rather than by a full definite determiner phrase, i.e. when the saliency of the second argument was increased. Thus, the accuracy in recognizing an ungrammaticality induced by the case feature of the second argument is dependent on the type of this argument. Furthermore, we found that the accuracy in detecting such case ungrammaticalities is distance sensitive insofar as a shorter distance leads to a higher accuracy. The results are taken as support for an "expectationdriven" parse strategy in which the way the parser uses the information of a current input item depends on the expectation resulting from the parse carried out so far. By contrast, "input-driven" parse strategies, such as the diagnosis model (Fodor \& Inoue, 1999) are unable to explain the data presented here.}, language = {en} } @article{SchlesewskyFrisch2003, author = {Schlesewsky, Matthias and Frisch, Stefan}, title = {Nominative case as a multidimensional default}, series = {Linguistics in Potsdam}, journal = {Linguistics in Potsdam}, number = {21}, issn = {1616-7392}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-32447}, pages = {61 -- 72}, year = {2003}, abstract = {The present paper addresses a current view in the psycholinguistic literature that case exhibits processing properties distinct from those of other morphological features such as number (cf.

In a speeded-acceptability judgement experiment, we show that the low performance previously found for case in contrast to number violations is limited to nominative case, whereas violations involving accusative and dative are judged more accurately. The data thus do not support the proposal that case per se is associated with special properties (in contrast to other features such as number) in reanalysis processes. Rather, there are significant judgement differences between the object cases accusative and dative on the one hand and the subject nominative case on the other. This may be explained by the fact that nominative has a specific status in German (and many other languages) as a default case.}, language = {en} } @article{VogelFrisch2003, author = {Vogel, Ralf and Frisch, Stefan}, title = {The resolution of case conflicts}, series = {Linguistics in Potsdam}, volume = {21}, journal = {Linguistics in Potsdam}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, issn = {1616-7392}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-32466}, pages = {91 -- 103}, year = {2003}, abstract = {This paper reports the results of a pilot study on the resolution of case conflicts in German free relative constructions.

The synchronization analysis shows an effect of global desynchronization in the theta band around 288ms after stimulus presentation for the semantic incongruity, while the physical mismatch elicits an increase of global synchronization in the alpha band around 204ms.
