In the first study, 20 male and 20 female volunteers were studied under threat-of-shock and no-threat conditions with respect to anxiety levels, skin conductance, EEG auditory evoked response, and alpha-blocking variables. The threat-of-shock increased anxiety levels, skin conductance level, and fluctuations. The P300 component of the AER was greater in anxious individuals and habituation of the alpha-blocking response was retarded. In the second study, 12 anxious patients were compared with 12… 
Skin Conductance Response Habituation to Nonphobic Stimuli in Anxiety Disorder Patients
Skin conductance habituation was compared between 38 patients meeting DSM-111 criteria for Panic Disorder and 29 normal controls. Approximately half of each group was randomly assigned to be given
Measuring the time course of anticipatory anxiety using the fear-potentiated startle reflex.
The time course of the facilitation of the acoustic startle reflex induced by anticipation of electric shocks was measured and the magnitude of this fear-potentiated startle effect became progressively larger in the threat condition the longer the light was on and then abruptly decreased with the onset of the light signaling the no-threat condition.
Orienting reaction habituation in chronic alcoholics
The study showed a significantly lower resistance to habituation of the orienting reaction in alcoholics than in normal control subjects and the severity of this habituation disturbance depended on the patients’ age, type of alcoholism, alcohol consumption intensity and chronicity, as well as the type of resting EEG.
Retention of orienting reaction habituation in chronic alcoholics
The study showed significant retention disturbances of orienting reaction habituation, or the “saving” of stimulations, achieved from one session to the other to obtain the habituation criterion, the savings being less in alcoholics than in control subjects.
Startle reflex modulation and autonomic responding during anxious apprehension in panic disorder patients.
The present study explored anxious apprehension in panic disorder patients and controls in two threat conditions, darkness and threat of shock, to suggest that only panic patients without depression belong to the fear disorders spectrum whereas panic patients with comorbid depression might rather belong toThe distress disorders profile.
Autonomic recovery and habituation in social anxiety.
Despite greater reports of anxiety experience in the HTSA versus the LTSA participants, autonomic measures showed comparable reactivity, habituation, and recovery in the two anxiety groups, supporting theories of social anxiety that emphasize cognitive factors.

Effects of Anticipatory Anxiety on Emotion Processing
Despite overall potentiated startle blink magnitude in threat-of-shock conditions, the startle reflex remained sensitive to hedonic picture valence, and defensive activation by physical threat operated independently from reflex modulation by picture media.
Habituation of orienting reaction in night terrors
The habituation changes found in patients with night terrors may be ascribed to the nervous disorders of functional and/or organic nature which generated also the night terror episodes.
