“…to be significantly higher in 20 patients suffering from anxiety states (17 of them showing "free floating" anxiety all the time), as compared to 20 matched normal controls. An elevated level of tonic EDA during resting conditions in anxiety patients, mostly confirmed by later studies (e.g., Chattopadhyay & Biswas, 1983;Raskin, 1975), had been interpreted as being due to a general "overarousal" in these patients, as already postulated by Malmo (1957).…”

A quartercentury later the scientific study of psychology also originated in Germany. Over time, however, the focus of psychological research, including the then new field of psychophysiology, shifted to the United States and Great Britain. This trend to the dominance of the United States and Great Britain was prolonged by the devastation of World War II and its aftermath in Germany (and elsewhere in continental Europe). Slowly at first and then more rapidly, German psychological science, including psychophysiology, recovered. For several decades German psychophysiologists have been a major force in psychophysiology. With the publication of the first English edition of this book in 1992, it became essential for electrodermal researchers worldwide again to learn from our German colleagues.When I came into psychophysiology in the mid-1960s, electrodermal activity was the most common system studied. Because of its popularity, a large literature had emerged on the physiological mechanisms producing these changes in the electrical properties of the skin and on the best methodology for recording them. Major reviews and/or chapters had been published or soon were to be published by Peter Venables and Irene Martin, Robert Edelberg, and David Lykken. Later reviews and articles were published by Venables and Margaret Christie, and by me. A chapter in 1990 by Michael Dawson, Anne Schell, and Diane Filion was especially noteworthy for its coverage of the psychological applications of electrodermal measures.Note that all these publications were journal articles and chapters and that most of them focused almost entirely on mechanisms and methodology. The publication of this book, first in German and then in English, provided the first book on electrodermal activity, and one that extensively covers psychological applications as well as mechanisms and methodology. Again to quote David Lykken back in 1992, "The return of German scholarship to what I shall loftily call the high table of psychophysiology is exemplified by this fine book, the most comprehensive treatise on the electrodermal system to appear in any language . . ." I completely agree with v that evaluation. Professor Boucsein's outstanding scholarship has produced a book of such breadth of coverage ...

“…In addition, the fact that most of the diagnostic groups tested in this study show quite similar associations of the habituation rate supports the validity of this index and confirms that EDR-HR comprises a noteworthy idiosyncratic element [19]. Furthermore, the important contribution o f'state' anxiety and depersonal ization to the overall EDR-HR variance in the total number of patients is a finding that keeps pace with pre vious reports in clinical populations [4,6,9,18]. It is of interest to note that separate analyses across diagnostic groups indicate that such contributions to the EDR-HR variance may coincide with some long-standing views concerning the psychopathology of these groups.…”

“…With respect to the first research direction, it has been consistently found that anxious patients are slow habituators [4,6,9]. However, slow ness of habituation is not an exclusive characteristic of anxious patients, frequently being observed in other pa tient groups as well as in normal subjects under certain conditions [10,11].…”

As far as the second research direc tion is concerned, it has been suggested that the relation of EDR-HR to the level of arousal could be utilized as an index in order to taxonomically evaluate different diag nostic groups [4], However, the clinical meaningfulness of such a categorization is also questionable due to the fact that first, the habituation/arousal relations may be influenced by cognitive ('threat appraisal') factors [9] and second, diverse disorders may show quite similar habituation/arousal patterning [12].…”

Clinical Significance of the Electrodermal Habituation Rate in Anxiety Disorders

1989

Neuropsychobiology

The electrodermal response habituation rate (EDR-HR) is examined in relation to clinical, personality and electrodermal measures in patients with generalized anxiety, phobic, obsessive-compulsive, dysthymic and conversion disorders by means of a stepwise regression analysis procedure. The results in the entire sample suggest that EDR-HR depends on the phasic component (amplitude and spontaneous activity) of the electrodermal response as well as on state anxiety, extraversion and depersonalization. When tested separately, most of the diagnostic groups demonstrated main trends similar to those found in total patients. A noteworthy correspondence between the importance of the contribution of certain clinical symptoms to the EDR-HR variance and some long-standing views of psychopathology was also found during the separate analysis of the groups. Although these findings question the diagnostic specificity of EDR-HR, the importance of this index as an objective measure of change following a therapeutic intervention as well as its potential usefulness in high-risk studies of anxiety disorders is put forward.

“…Within the affective literature, there has been a particular emphasis on understanding deficits in habituating to aversive stimuli. A slower rate (or lack) of response reduction to a non-threatening stimulus has been considered to be maladaptive and an index of heightened vigilance (Oken et al, 2006), difficulty in flexibly responding to environmental challenges (Raskin, 1975; Siddle, 1991), and/or deficits in inhibitory learning (Craske et al, 2008). …”

Association between respiratory sinus arrhythmia and reductions in startle responding in three independent samples

Evidence suggests that respiratory sinus arrhythmia (RSA) may be an important indicator of physiological flexibility. However, few studies have examined the relation between RSA and defensive habituation, a process contingent on physiological flexibility. In three independent samples, habituation was defined as the time course of 9 startle responses. In Sample one and two, startle was recorded (1) while shock electrodes were attached to participants’ and (2) before a threat-of-shock task. In Sample three, startle was recorded without these two components. In the first two samples, startle magnitude significantly decreased over time but in Sample three, startle only decreased at a trend level. Further, low RSA was associated with less of a reduction in startle magnitude over time within the first two samples, but was unrelated to startle reduction in the third. This suggests that low RSA is associated with less habituation to contextual anxiety, which may reflect difficulties regulating anxiety.
