Event-related brain potentials (EMS) were recorded while normal German subjects read either simple declarative sen- tences made up from real German words, or sentences that contained German pseudo-words instead of nouns and verbs. The verb (pseudo-verb) of the sentences disagreed in number with the subject noun (pseudo-noun) in 50% of the sentences. The(More)
Closed class (determiners, pronouns, conjunctions, prepositions etc. ) and open class (nouns, verbs, adjectives, adverbs) words have different linguistic functions and have been proposed to be processed by different neural systems. Here, event-related potentials (ERPs) were recorded in young German-speaking subjects while they read closed class and open(More)
One of the current issues in the investigation of language by means of event-related brain potentials (ERPs) is whether there is an ERP effect that can be specifically related to the processing of syntactic information. It has been claimed that a late positivity (P600 or SPS-syntactic positive shift) occurring to syntactic violations or ambiguities(More)
Event-related brain potentials (ERPs) were recorded from multiple scalp locations from young human subjects while they performed two different face processing tasks. The first task entailed the presentation of pairs of faces in which the second face was either a different view of the first face or a different view of a different face. The subjects had to(More)
OBJECTIVES The present investigation explored the electrophysiological correlates of working memory during sentence comprehension. METHODS Event-related brain potentials (ERP) were recorded from 29 channels in 22 subjects, while they read German sentences having subject-first (canonical) or object-first (non-canonical) word orders. RESULTS Three(More)
Ten patients suffering from post-traumatic stress disorder (PTSD) following a severe traumatic event, were assessed with event-related brain potentials (ERPs) in a modified oddball paradigm containing auditory standard, target, and novel tones. ERPs were assessed before and after a treatment session using the eye movement desensitization and reprocessing(More)
The purpose of this study was to investigate electrophysiological correlates related to the recognition of repeated faces in the intact human by means of event-related brain potentials (ERPs). A group of young healthy adults performed a continuous face recognition task, in which 240 unfamiliar faces were flashed upon a computer screen with 80 of the faces(More)
OBJECTIVE Fronto-striatal dysfunction has been discussed as underlying symptoms of Tourette syndrome (TS) with co-morbid Obsessive Compulsive Disorder (OCD). This suggests possible impairments of executive functions in this disorder, which were therefore targeted in the present study. METHODS A comprehensive series of neuropsychological tests examining(More)
In order to determine if an event-related brain potential (ERP) effect described for syntactic violations (P600/SPS) varies with the amount of reprocessing entailed by a violation, number incongruencies were presented either within simple declarative or within subordinate clauses. ERPs were recorded while 12 German subjects read the stimulus materials(More)
Twelve healthy volunteers were tested in a double-blind crossover study to assess the effects of oxazepam and an extract of kava roots (Piper methysticum) on behavior and event-related potentials (ERPs) in a recognition memory task. The subjects' task was to identify within a list of visually presented words those that were shown for the first time and(More)
