Impaired attentional functioning, as found in patients with schizophrenic disorders, may covary with impaired SCP regulation. This hypothesis was tested using a self-regulation paradigm. Twelve medicated male schizophrenic inpatients and 12 healthy male controls received continuous feedback of their SCPs, during intervals of 8 s each, by means of a visual stimulus (a stylized rocket) moving horizontally across a TV screen. The position of the feedback stimulus was a linear function of the integrated SCP at each point in time during the feedback interval. Subjects were required to increase or reduce negative SCPs (referred to pretrial baseline) depending on the presentation of a discriminative stimulus. The correct response was indicated by the amount of forward movement of the feedback stimulus and by monetary rewards. Schizophrenics participated in 20 sessions (each comprising 110 trials), while controls participated in 5 sessions. Compared with the healthy controls, schizophrenics showed no significant differentiation between negativity increase and negativity suppression during the first sessions. However, in the last 3 sessions, patients achieved differentiation similar to controls, demonstrating the acquisition of SCP control after extensive training.</dcterms:abstract> <dc:creator>Mattes, Regina</dc:creator> <dc:contributor>Schneider, Frank</dc:contributor> <dc:creator>Heimann, Hans</dc:creator> <dc:creator>Schneider, Frank</dc:creator> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dspace:isPartOfCollection rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/43"/> <dc:contributor>Rockstroh, Brigitte</dc:contributor> <dc:creator>Bartels, Mathias</dc:creator> <dcterms:isPartOf rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/43"/> <dc:creator>Elbert, Thomas</dc:creator> <dcterms:hasPart rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/11035/1/Elbert_1992_Self_Regulation_of_slow.pdf"/> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:contributor>Bartels, Mathias</dc:contributor> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/11035"/> <dc:contributor>Birbaumer, Niels</dc:contributor> <dc:language>eng</dc:language> <dc:creator>Birbaumer, Niels</dc:creator> <dc:creator>Rockstroh, Brigitte</dc:creator> <dc:contributor>Heimann, Hans</dc:contributor> <dcterms:bibliographicCitation>First publ. in: Biofeedback and Self-Regulation 17 (1992), 4, pp. 277-292</dcterms:bibliographicCitation> <dcterms:rights rdf:resource="http://creativecommons.org/licenses/by-nc-nd/2.0/"/> <dc:contributor>Mattes, Regina</dc:contributor> <dc:creator>Lutzenberger, Werner</dc:creator> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-25T09:24:56Z</dcterms:available> <dcterms:title>Self-Regulation of Slow Cortical Potentials in Psychiatric Patients : Schizophrenia</dcterms:title> <dcterms:issued>1992</dcterms:issued> <dc:format>application/pdf</dc:format> <dc:contributor>Elbert, Thomas</dc:contributor> <dc:rights>Attribution-NonCommercial-NoDerivs 2.0 Generic</dc:rights> </rdf:Description> </rdf:RDF>
