The More or Less Startling Effects of Weak Prestimulation.

Weak lead stimulation can modify the human startle reflex. It is proposed that, with the aid of physiological measures taken in the interval between lend and startle stimuli, this paradigm offers a promising method of Investigating different levels of central processing, the operation of a short time-constant as opposed to a long time-constant stem, and the operation of an orienting-attentional as opposed loan intensity-dependent activational system.
