The time course of the facilitation of the acoustic startle reflex induced by anticipation of electric shocks was measured in 20 normal volunteers. Shocks could be administered during the last 10 s of 45-s threat conditions but not during 50-s no-threat conditions, each condition being signaled by a different light. Consistent with previous data, overall eyeblink startle levels were higher during the threat than during the no-threat conditions. However, the magnitude of this fear-potentiated… CONTINUE READING
