Weak lead stimulation can modify the human startle reflex It is proposed that, with the aid of
physiological measures taken in the interval between lead 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 system, and the
operation of an orienting‐Attentional as apposed an Intensity dependent activational system.
