Towards this end, pleasant, neutral and unpleasant pictures were presented as a continuous stream during alternating threat-of-shock and safety periods, which were cued by colored picture frames. Orbicularis-EMG to auditory startle probes and electrodermal activity were recorded. Previous findings regarding affective picture valence and threat-of-shock modulation were replicated. Of main interest, anticipating aversive events and viewing affective pictures additively modulated defensive activation. Specifically, despite overall potentiated startle blink magnitude in threat-of-shock conditions, the startle reflex remained sensitive to hedonic picture valence. Finally, skin conductance level revealed sustained sympathetic activation throughout the entire experiment during threat- compared to safety-periods. Overall, defensive activation by physical threat appears to operate independently from reflex modulation by picture media. The present data confirms the importance of simultaneously manipulating phasic-fear and sustained-anxiety in studying both normal and abnormal anxiety.</dcterms:abstract> <dc:creator>Guerra, Pedro M.</dc:creator> <dc:contributor>Schupp, Harald T.</dc:contributor> <dc:creator>Vila, Jaime</dc:creator> <dc:creator>Bublatzky, Florian</dc:creator> <dc:contributor>Guerra, Pedro M.</dc:contributor> <dc:language>eng</dc:language> <dc:creator>Pastor, Maria Carmen</dc:creator> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2013-02-12T12:26:44Z</dc:date> <dc:creator>Schupp, Harald T.</dc:creator> <dc:rights>deposit-license</dc:rights> </rdf:Description> </rdf:RDF>
