Show moreThis study examines the effect of foreign-accented speech on the predictive ability of our brain. Listeners actively anticipate upcoming linguistic information in the speech signal so as to facilitate and reduce processing load. However, it is unclear whether or not listeners also do this when they are exposed to speech from non-native speakers. In the present study, we exposed native Dutch listeners to sentences produced d non-native speakers while measuring their brain activity using electroencephalography. We found that listeners’ brain activity differed depending on whether they listened to native or non- native speech. However, participants’ overall performance as measured by word recall rate was unaffected. We discussed the results in relation to previous findings as well as the automaticity of anticipation.

Show moreThis Event-related Potential (ERP) study examines the licensing of NPIs in Dutch in a grammatical configuration where the NPI linearly precedes its licensor. It investigates how the addition of modifiers at two different structural positions in the sentence affects differently the process of actively searching for an upcoming licensor. We measured the ERPs elicited at the licensor position by comparing conditions with modifiers at two different structural positions, with a control condition where no modifier was added, where all the tested conditions were grammatical. In addition, we examined whether adding different number of modifiers at the two structural positions affects the processing of the licensor differently. Our results show that there is a central anterior negativity elicited at the licensor in conditions with modifiers at the structural position where a licensor could occur in comparison to the control condition without modifiers. Further, there is an amplitude difference shown for the central anterior negativity when these conditions differ in the number of modifiers. In comparison, an ERP component with a reduced amplitude was elicited at the licensor for conditions with modifiers at a structural position where the licensor cannot occur, when compared with the control condition. We suggest that our results show evidence that the parser is sensitive to structural relations in the on-line licensing of NPIs. Show less

Show moreTo interpret (1) a process of semantic recovery is required when we process the "elliptical" right conjunct. (1) John likes bananas, and Sally pears. In (1) the message of the right conjunct is that Sally *likes* pears; she did not - for example - steal them. Somehow we can retrieve a missing element and integrate it with the remaining elements. This dissertation investigates the processing of ellipsis, in particular the ellipsis type Gapping and its sub-type Stripping. After a thorough review of the theoretical and experimental background on Gapping (and Stripping), five electrophysiological studies are reported -- including one replication study. Using the method of event-related (brain) potentials, questions are tackled regarding the nature of syntactic, semantic and prosodic processes and how they interplay. Two mechanisms described in the experimental literature -- "Copy alpha" and "cue-based retrieval" -- are drawn upon to connect theory to processing. It is true that a mapping between existing theoretical insights and actual processing may be problematic, however, commensurate with theoretical insights, all experimental findings underscore the multidimensional nature of Gapping and Stripping. It is further argued that ellipsis resolution is sustained by a two-stage mechanism that is based on retrieval and integration processes. Show less
