“…In a study with 21 participants, Wilcott (1963) observed a SRL decrease during an increase of the room temperature up to 65.5 C. Additional variations of the SRRs in amplitude and shape which he observed were not conclusive, as his stimulus conditions under different temperatures were not comparable. Grings (1974) reported a SRL decrease of 3%/ C; a value which had also been reported for skin temperature variations by Edelberg (1972a).…”

“…J€ anig et al (1983) reported palms and soles taking part in thermal sweating only at high ambient temperatures. Whereas Wilcott (1963) observed palmar and plantar sweat production following thermal stimulation, Schliack and Schiffter (1979) reported that palms and soles remained dry while the rest of the body was vigorously sweating, for example, when they were held out of a hot bath. In a study performed with 34 participants, Kerassidis (1994) demonstrated that in ambient temperatures up to 60 C the amount of palmar and plantar thermal sweating is negligible compared to that on the thorax and the forehead.…”

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 ...

“…This suggests that arousal sweat-ing is a protective reflex which acts to increase the resistance of the skin to mechanical injury. The presence of arousal sweating over the general body surface, such as the chest (Wilcott, 1963), seems to fit in with its role as a protective reflex. In addition, the fact that arousal sweating is the most prominent at the palmar and plantar surfaces, body areas that normally come in direct contact with the environment, and also at the axilla (Kuno, 1934), a body area vunerable to physical assult, is in agreement with the conclusion that it serves a protective function.…”

The following five experiments are reported. After palmar sweating is abolished by atropine, the skin is easier to drill with a dental burr. This suggests that arousal sweating protects the skin against mechanical injury. Intracutaneous injection of acetylcholine or mecholyl at the forearm will produce skin potential (SP) effects of both negative and positive polarity and also a reduction in skin resistance (SR). This suggests that a cholinergic substance is involved in the production of SP and SR. Intracutaneous injection of mecholyl at the forearm will either lower or raise the pain threshold to a needle prick. A lowering of the pain threshold was associated with the presence of an SP negative effect and a rise was associated with an SP positive effect. It is concluded that the adaptive value of the cholinergic substance related to SP and SR is to modulate cutaneous sensitivity. The pain threshold to an electric shock can be lowered or raised by mecholyl injection. This may show that the pain threshold can be varied by mecholyl injection independently of its effects on sweating. Lowering of the electric shock pain threshold at the palm is associated with the appearance of both SP negative and positive responses. This further demonstrates a relation between SP activity and pain sensitivity but indicates that the direction of the change in the pain threshold is not dependent on SP response polarity.

“…By comparison, thermoregulation at high temperatures involves methods of heat dispersal that are distinct from psychophysiological responding. Thermal sweating is less pronounced on the palms than on the general body surface (Machado‐Moreira, Caldwell, Mekjavic, & Taylor, ; Taylor & Machado‐Moreira, ), and this discrepancy should allow a detectable increase in palmar sweating and electrodermal activity in response to psychological stressors (Allen, Armstrong, & Roddie, ; Machado‐Moreira, Edkins, Iabushita, Maruca, & Taylor, ; Machado‐Moreira & Taylor, ; Wilcott, ). Moreover, heat‐induced vasodilation increases blood flow to the extremities (Frisancho, ; Rowell, ; Taylor et al, ), suggesting that vascular constriction should still be evident during polygraph questioning at high temperatures.…”

Temperature effects on polygraph detection of concealed information

Thermoregulatory influences on electrodermal and cardiovascular activity may interfere with the detection of concealed information using a polygraph. This possibility was assessed by means of a mock terrorism scenario. Seventy-two participants were assigned to either a guilty or an innocent role. They were given a polygraph test at one of three ambient temperatures: 10°C, 22°C, or 34°C. Among guilty participants, electrodermal and cardiovascular measures were least effective at 10°C. Electrodermal results were optimal at 22°C, whereas cardiovascular results were optimal at 34°C. Among innocent participants, the effectiveness of these same measures was not affected by ambient temperature. Temperature had no significant impact on respiration results within the guilty or the innocent groups. Taken together, these findings have implications for those who use polygraphs in uncontrolled testing environments.
