ABSTRACT
In a sentence reading ERP study in Swedish we investigated the roles of the N400 and P600 components. By manipulating ease of lexical retrieval and discourse integration of the critical words in four conditions (contextually primed/non-primed and degree of contextual fit), we explored these components from a sentence processing perspective. The results indicate that the N400 indexes lexical retrieval and access of stored conceptual knowledge, whereas the P600 component indexes pragmatic processes, such as integration of a word into the discourse context, or the information structural status of the word. The results support single-stream models of sentence processing where lexical retrieval and integration do not take place in parallel, as in multi-stream models.
ABSTRACT
This article reports the results from an ERP study on the processing of anaphoric reference to quantifying expressions in Swedish (e.g. Many students attended the lecture and that they were present was noted). Negative quantifiers (e.g. few) differ from positive quantifiers (e.g. many), in allowing anaphoric expressions to target either the ref(erence) set ('students attending the lecture') or the comp(lement) set ('students not attending the lecture'), while positive quantifiers only allow Refset continuations. Results from the present study show that negative quantifiers give rise to an enhanced frontal negativity at the anaphoric pronoun in the negative condition, relative to positive quantifiers. At the critical word disambiguating between a Refset and Compset reading, we found P600 effects for the anomalous relative to the non-anomalous conditions. We interpret the frontal negativity found with negative quantifiers as an indication of referential ambiguity interfering in the processing of anaphoric reference.

This paper presents the results from two studies on anaphoric reference to quantifying expressions (QEs) in Swedish, contributing to the current cross-linguistic discussion on this issue. For English it has been shown that the polarity of the QE (positive vs negative) determines the anaphoric set reference (to the referens set, REFSET, or to the complement set, COMPSET), while for Spanish it has been claimed that while REFSET interpretation is the default, the relative sizes of the two sets (REFSET and COMPSET) also matters. In Experiment 1, a semantic plausibility study. The results showed that for positive QEs, anaphoric reference can only be to the REFSET, while for negative QEs, it can only be to the COMPSET. Unlike in English and Spanish, REFSET continuations were categorically ruled out for negative QEs. To investigate whether the internal differences between QEs could be explained in terms of set size, we conducted Experiment 2, an estimation task. The results from this experiment showed that the size of the REFSET relative to the COMPSET was not a determining factor.

Relative clauses are considered strong islands for extraction across languages. Swedish comprises a well-known exception, allegedly allowing extraction from relative clauses (RCE), raising the possibility that island constraints may be subject to "deep variation" between languages. One alternative is that such exceptions are only illusory and represent "surface variation" attributable to independently motivated syntactic properties. Yet, to date, no surface account has proven tenable for Swedish RCEs. The present study uses eyetracking while reading to test whether the apparent acceptability of Swedish RCEs has any processing correlates at the point of filler integration compared to uncontroversial strong island violations. Experiment 1 tests RCE against licit that-clause extraction (TCE), illicit extraction from a non-restrictive relative clause (NRCE), and an intransitive control. For this, RCE was found to pattern similarly to TCE at the point of integration in early measures, but between TCE and NRCE in total durations. Experiment 2 uses RCE and extraction from a subject NP island (SRCE) to test the hypothesis that only non-islands will show effects of implausible filler-verb dependencies. RCE showed sensitivity to the plausibility manipulation across measures at the first potential point of filler integration, whereas such effects were limited to late measures for SRCE. In addition, structural facilitation was seen across measures for RCE relative to SRCE. We propose that our results are compatible with RCEs being licit weak island extractions in Swedish, and that the overall picture speaks in favor of a surface rather than a deep variation approach to the lack of island effects in Swedish RCEs.
