The present study investigated cortical and autonomic responses of aware participants using an instructed fear conditioning design. Steady-state visual evoked fields (ssVEF) and heart rate change were recorded to assess sensory processing and activation of the fear system by reinforced (CS+) and nonreinforced stimuli (CS-). Participants who showed heart rate acceleration demonstrated increased ssVEFs in visual and parietal cortex during CS+ in acquisition trials. Heart rate decelerators did not show enhanced cortical activation with respect to the CS+. Participants in both groups reported awareness of CS US contingencies. Awareness of stimulus contingency in fear conditioning seems not to be sufficient to elicit enhanced visual cortical processing.</dcterms:abstract> <dcterms:issued>2006-03</dcterms:issued> <dc:creator>Miller, Gregory</dc:creator> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103416863-3868037-7"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-07-04T12:26:15Z</dc:date> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/381"/> </rdf:Description> </rdf:RDF>
