Research Interests
Brain regions involved in language selection processes in bilinguals, brain basis of diglossia in the Arabic language among Arabic-Hebrew bilinguals, clinical case studies in neuropsychology.

Current Projects
During this year, we continued in collaboration with Prof. Jean-Marie Annoni from Geneva working on the ongoing project funded by the Swiss National Science Foundation. This project addresses the issues of semantic processing and language control mechanisms in the bilingual brain using both EEG and fMRI techniques. A paper is now submitted in relation to the fMRI part on the issue of language selection and another paper is in preparation for the semantic question in the bilingual brain. Regarding the projects conducted in the Safra Brain Research center at Haifa, several projects underwent pilot studies. For the project on language selection with a special emphasis on diglossia, a group of 24 subjects were recorded with EEG and ERP analysis has already been undertaken. For the study of the Arabic language among Arabic-Hebrew bilinguals, a behavioral pilot study was conducted using a visual lexical decision task. In this study we used spoken Arabic (SA, considered by some authors as a first language, L1) and literary Arabic (LA, considered by some authors as a second language, L2) words together with Hebrew to investigate the neural basis of diglossia in Arabic by means of ERP analysis. The hypothesis is that the status of SA as an L1 and LA as an L2 might be modality-dependant. This is to say that SA might function as an L1 in the auditory modality while in the written modality LA functions as L1. The behavioral results indeed showed that LA words induced the faster reaction times and the higher accuracy. The first EEG recording with this task has already been conducted and by the end of September a group of 30 subjects will be investigated. In the other part of the project, the same experiment will be undertaken using the auditory modality. In a recently developed project, we will developmentally investigate the effects of Arabic orthography on processes of word recognition in the visual modality. In addition, we will investigate the effects of the duration of word exposure (subliminally and supraliminally) on processes of word recognition in the visual modality in normal and dyslexic readers.
