Processing Ergativity: Behavioral and Electrophysiological Evidence

Author(s):  
Adam Zawiszewski

So far ergativity has been mostly studied from a language-theoretic perspective and the evidence on how it is processed and represented is rather scarce. In this paper I provide an insight into ergativity from an experimental approach. First, I present an overview of the experimental methods used to investigate ergativity (self-paced reading, event-related potentials and functional magnetic resonance imaging) and next I review studies that examined behavioral, electrophysiological and neuroanatomical correlates of ergativity in both native and non-native speakers, as well as those focused on the universality of processing strategies in ergative languages. Finally, I also review and discuss the experimental data from works that dealt with syntactic and semantic aspects of ergativity and discuss the implication of the results for future research.

This article describes the ways in which transcranial magnetic stimulation (TMS) can be a means of studying consciousness by interfering with the physical occurrences of the brain. The focus of this article is aspects of consciousness, i.e. being aware or unaware, and their cerebral basis. TMS has been used to demonstrate regional cortical functional specialization. The reasons for the effects caused by TMS are still not fully known. Further work must be done in order to address this problem. TMS can briefly impose (or disrupt) rhythmic discharge in the underlying cortex and some of these rhythms are thought to be important for selective attention and awareness. TMS can disrupt activity in underlying brain tissue with millisecond precision but thus far it is usually used in isolation. When combined with event-related potentials and functional magnetic resonance imaging its usefulness will expand.

The field of neuroimaging has experienced a tremendous boom due to technological advances in the last ten years and this is also reflected in the electroencephalography / event-related potentials (EEG/ERP) method. This contribution provides an overview of the main EEG/ERP hardware systems and software development currently on the market and the benefits of such technology for the study of language issues. We discuss the “added-value” such technology brings to the research of language and the possibilities of combining various neuroimaging technique with emphasis on the integration of EEG/ERP and functional magnetic resonance imaging (fMRI). Our contribution ends with a look at what we think may be the methodologies that drive the field forward in the not too distant future.

The neuronal correlate of a rare explicit bidirectional synesthesia was investigated with numerical and physical size comparison tasks using both functional magnetic resonance imaging and event-related potentials. Interestingly, although participant I.S. exhibited similar congruity effects for both tasks at the behavioral level, subsequent analyses of the imaging data revealed that different brain areas were recruited for each task, and in different time windows. The results support: (1) the genuineness of bidirectional synesthesia at the neuronal level, (2) the possibility that discrepancy in the neuronal correlates of synesthesia between previous studies might be task-related, and (3) the possibility that synesthesia might not be a unitary phenomenon.
