This study presents results from a sentence completion test that examines the production of finite main clauses and non-finite relative clauses in Turkish agrammatic speech. In main clauses, the verb is finite and all its constituents are in their base positions. In relative clauses, the verb is a participle and the NP undergoes overt movement to an A-bar position. The results show that non-fin...

In this article, the authors test one of the central claims of the Dual-Mechanism Model (Pinker and Prince, 1994), that is, that regular inflection equals default inflection. Based on results from an elicitation task with eight agrammatic Broca's aphasics and a lexical decision task with unimpaired subjects, the authors show that this assumption is not borne out. Their data on German plural inf...

Topographical evaluation of aphasic brain lesions can enhance our knowledge of cognitive physiology and plasticity. This prospective study was conducted on 100 stroke-afflicted patients with aphasia admitted in Valie-Asr Hospital (Khorasan, Iran) in 2003. Topography of infarct lesions was detected by a neurologist based on the map of brain vascular territories in CT-scan. Aphasic lesions catego...

We address short-term memory development and the role of covert verbal rehearsal (CVR), the imagined pronunciation of items from a list to be recalled. We suggest insights based on studies of serial and free recall. The research in adults has taken two tacks. (1) Overt rehearsal responses have been elicited to study what CVR strategies may occur, and (2) conditions have been imposed impeding th...

We used event-related functional magnetic resonance imaging (erfMRI) to investigate the neural basis of biological and syntactic gender integration during pronoun processing in German sentences about persons or things. German allows for separating both processes experimentally. Overall, syntactic processing activated areas adjacent to Broca's area (BA 44), whereas processing of the biological s...

Current views on the neurobiological underpinnings of language are discussed that deviate in a number of ways from the classical Wernicke-Lichtheim-Geschwind model. More areas than Broca's and Wernicke's region are involved in language. Moreover, a division along the axis of language production and language comprehension does not seem to be warranted. Instead, for central aspects of language pr...

Language processing is supported by different regions located in separate parts of the brain. A crucial condition for these regions to function as a network is the information transfer between them. This is guaranteed by dorsal and ventral pathways connecting prefrontal and temporal language-relevant regions. Based on functional brain imaging studies, these pathways' language functions can be a...

Dual tasking or action cascading is essential in everyday life and often investigated using tasks presenting stimuli in different sensory modalities. Findings obtained with multimodal tasks are often broadly generalized, but until today, it has remained unclear whether multimodal integration affects performance in action cascading or the underlying neurophysiology. To bridge this gap, we asked ...

The Generalized Minimality approach to comprehension difficulties with non-local dependencies (Grillo 2005, 2008) predicts that in non-local dependencies (e.g. object relatives) a partial match in internal structure between the moved and the intervening DP can generate a minimality effect and lead to comprehension difficulties in several populations, including children and agrammatic Broca's ap...
