One of two neutral pictures (CS+) either coterminated with (delay group; n=32) or was followed by the aversive unconditioned stimulus (UCS) after CS offset (trace group; n=32), while startle blink and skin conductance responses (SCR) were measured. As expected, the acquisition of conditioned startle potentiation in delay conditioning was independent of contingency awareness. In contrast, fear-potentiated startle in trace conditioning was only observed for those participants who were aware of the CS-UCS contingencies. SCR conditioning was generally only obtained for aware participants. The present results suggest a more implicit learning process in delay fear conditioning, whereas the explicit acquisition of contingency awareness might be a prerequisite for trace fear conditioning.</dcterms:abstract> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103416863-3868037-7"/> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-25T09:21:05Z</dcterms:available> <dc:rights>deposit-license</dc:rights> <dc:contributor>Hamm, Alfons O.</dc:contributor> <dc:format>application/pdf</dc:format> <dc:language>eng</dc:language> <dcterms:title>Fear acquisition requires awareness in trace but not delay conditioning</dcterms:title> <dc:contributor>Weike, Almut I.</dc:contributor> </rdf:Description> </rdf:RDF>
